I.—Notice of Producti found i the Western States and Territories, with descriptions of twelve New Species. By J. C. Norwoop and Henry Prarten, of the Illinois Geological Survey. The genus Productus, established by Mr. Sowerby, in 1814, being found so abun- dantly in the “mountain limestone,” of Europe, it was natural to suppose, that when this formation, which is so extensively developed in our Western and Southern States, came to be explored, it would yield many more species than it was known to furnish when M. de Koninck published his admirable monograph on the Producti, in 1847. This expectation has, in some degree, been realized; twelve new species being now added to the published catalogues of American and European paleontologists. The wide distribution of this formation in North America, occupying, as it does, extensive districts in the States of Kentucky, Indiana, Illinois, Missouri, Iowa, Ten- nessee, Alabama, and Arkansas, together with Nebraska territory, as well as on the Humboldt river, in Utah, we may reasonably expect that the present list will be ereatly extended, especially when the State collections of Missouri, Ilinois and Ken- tucky come to be examined and collated. It is not, however, in the “mountain limestone” alone that the Producti are so widely distributed. ‘The marine limestones and calcareous clays of the coal measures are equally, if not still more, prolific in species of this genus. Many of the species in the following list are found, exclusively, in that formation; and, with a few species of other genera, are the most reliable indicators in the exploration of our Western coal fields. VOlen Tite 2 -- — eee 6 NORWOOD AND PRATTEN ON PRODUCTI. In the Devonian limestones we have met with only two species, both of which are also found in Europe. One of them, the P. Murchisonianus, it is certain, also belongs to the upper Silurian rocks of Indiana. Several of the species described were found by Mr. Pratten in the Western part of Missouri, and on the Nemahaw river, in Ne- braska, in a limestone, the age of which has not been yet determined. In the “Report on the Geology of Wisconsin, Iowa, and Minnesota,” Dr. D. D. Owen mentions having found the P. marginalis. As we have not met with that species, it is not included in the present catalogue. He also indicates several new species from North-western localities, of which it is to be hoped he will before a publish descriptions. At the time M. de Koninck’s work was published, the whole number of species known was sixty-two. Dr. D. D. Owen added one from the U. 8. Survey. We have now added twelve, which makes the number of the species known, in all countries, up to the present time, seventy-five. It may also be seen, by consulting M. de Koninck’s work, that, at the time of publication (1847), the whole number of species known to occur in the United States and Territories amounted only to seven.. They now num- ber thirty, and the probability is, that future investigations will greatly extend the catalogue. For the beautiful and accurate drawings of the species now published, we are entirely indebted to Mr. H. A. Ulffers, of the Illinois State Survey. MOLLUSCA BRACHIOPODA. Genus Propuctus, Sowerby.

This beautiful Productus is very widely distributed in the Western States. ; P. ALTONENSIS, nob.—PI. I., fig. 1, a, 0. ¢. Shell of a medium size, dorsal valve regularly vaulted and strongly curved on itself, very much inflated, geniculated, anterior part flattened. Beak swollen, and passing beyond the cardinal border. Surface covered with a great number of slender, filiform ribs, which frequently bifurcate, while occasional new ones are implanted between the old ones. This shell appears to have been rather irregular in its growth, for, while some specimens are slightly transverse, others are a little longer than broad. The sides are flattened, so as to fall almost perpendicularly on the ears, which are small, and crossed by several undulating folds, as in the P. cora; they are, however, sharper and more numerous than in that species. Two or three ranges of small tubercles are placed on these folds. Some of the specimens show that there have been ranges of tubes across the anterior portion of the shell, somewhat similar to those on occasional specimens of the P. Flemingii. In addition to these, a few tubes are scattered over the remainder of the surface. The ventral valve is very regularly concave on the visceral portion, but becomes more abruptly bent as it approaches the other valve, so as to follow it in its anterior prolongment, which is, however, short. Its ribs are like those of the dorsal valve ; the ears have a few folds, with slender tubercles, like those of the dorsal valve. The visceral part is also crossed by several folds, which become very indistinct as they approach the centre of the shell. Dimensions.—Length, 25 millimetres; thickness, 9 millimetres. At the distance of 20 millimetres from the beak, the ribs number 18 in the space of 10 millimetres. Comparisons and Differences—This shell approaches more nearly to the P. cora, in its general appearance, than any other species of the genus we have met with. It may, however, be easily distinguished from that species by the greater regularity of its ribs, which are not bent and contorted, as they are in the P. cora; by the size of the ribs, which are larger in the P. Altonensis ; and by the greater number of small tubercles with which its surface, especially the anterior part, is furnished. It is still more distinctly marked by the lines of increment which cross the ribs on their ante- rior prolongment, and give to that portion of the shell a reticulated appearance, par- ticularly when seen through a lens. This characteristic is never met with in the P. cora. From the P. Flemingii it may be easily distinguished by the absence of a sinus, and by the non-reticulation of the visceral portion. It cannot be con- founded with any other known species than those above mentioned. Locality and Geological Position—Alton, Illinois, in the upper portion of the moun- tain limestone series. 8 NORWOOD AND PRATTEN ON PRODUCTI. Explanation of the figures.—Pl. I, fig. 1, a.

The same seen in profile. P. Paiturpsi, nob. PI. I., fig. 2, a, 8, ¢. Shell rather small, nearly as long as broad, dorsal valve slightly gibbous, its ante- rior part flattened, with a wide shallow sinus on old specimens, while young ones do not show it. The beak, although slightly enrolled on itself, does not pass the cardinal border. The ears are small, flattened and smooth, showing no trace of either folds or tubes. The surface is covered with coarse, irregularly sized ribs, which are gene- rally broader than the furrows separating them. Many of the ribs are bifurcated. The cardinal line measures four-fifths of the greatest breadth of the shell. The sides fall perpendicularly on the ears. The only traces of tubes are a few indistinct ones on the flanks. Ventral valve concave, with a very slight varix. The visceral disk has ribs similar to those on the other valve; beyond the disk they are obliterated, the surface being covered with nine or ten broad lamella, the edges of which are turned sharply upward, presenting acute wavy ridges, which are continued on to the cardinal border on each side. Dimensions.—Length, 19 millimetres. Proportions—Length 100, breadth 100, thickness .047. Ribs.—Near the anterior border there are from eight to ten in the space of ten mil- limetres, and number, altogether, about twenty-eight. Comparisons and Differences—By the coarse irregular ribs of the dorsal valve, by the visceral portion of the ventral valve possessing ribs, together with the broad, ridged lamellee around it, this species may be easily distinguished from any other. It does not appear to have possessed an anterior prolongment, as its present front is without one, and is bounded by a sharp margin. Geological Position and Locality— Mr. Pratten found this in Utah Territory, at the “ Big Caiion” of Humboldt river. It occurs in the mountain limestone, associated with P. semireticulatus of Martin, and the Spirifer tricornis of de Koninck. + Explanations of the Figures —Pl. I, fig. % a. View of the dorsal valve.

Geological Position and Localities—In Belgium this shell belongs to the mountain limestone series, while in this country we have found it only in the coal measures, and as yet at only three localities, Caseyville, Illinois, and two places in Posey county, Indiana. At Caseyville it occurs in a thick bed of limestone, overlying the five foot seam of coal. [Illinois State Collection. P. Rocrrsi.—nob. Pl. L., fig. 3, a, 0, c. Shell of medium size; slightly transverse; dorsal valve very high and strongly enrolled on itself; cardinal border equal to about four fifths of its greatest transverse diameter; beak rather large, and passing beyond the cardinal border; ears but little distinct from the dorsal vault. ‘The anterior part is flattened, and possesses a slight sinus. The surface is covered with ribs, of which twelve may be counted in the space of ten millimetres, at the distance of ten millimetres from the beak. It is also covered in its whole extent with transverse folds. Those nearest the beak are rather small, but, after passing the visceral disk they rapidly increase in size to near the middle of the shell, after which they again decrease in size to the margin. The whole anterior portion of the shell seems to have been pretty thickly covered with tubercles, especially between the transverse bands, while a few were distributed over the remainder of the surface. On the middle part of the shell there are only — transverse bands in the space of ten millimetres. Dimensions.—Length, 21 millimetres; breadth, 24 millimetres. Comparisons and Differences.— Although we have only one specimen of this species, and from this one the shell is abraded over the greater portion of its surface, still its form and characteristics are so distinct that it cannot be confounded with any other. The P. undatus comes nearest to it, but our species differs from the undatus in having larger ribs, and flattened transverse bands, while the bands of the wndatus are sharp. The P. Rogersii is further distinguished by having its anterior prolongment covered with tubercles, some of which, judging from a few remaining fragments, must have been of considerable length. Ventral valve unknown. Geological Position and Locality—This specimen was found by Mr. Pratten in the coal measures, near Huntsville, Missouri. It occurs in a bed of ferruginous limestone overlying a stratum of bituminous shale. Explanation of the Figures—Pl. I., fig. 8, a. View of the dorsal valve. H. Pratten’s collection.

This species is dedicated to our friend, Prof. Henry D. Rogers, as a slight testimony of our high appreciation of his labors in American geology. Section III. PRODUCTI PROBOSCIDEI. Propuctus cLAvuS, nob.—PIl. I., fig. 4, a, 6, ¢. This very singular shell is the only one of the class we have met with, and it is in so imperfect a state of preservation that for some time we hesitated about including it in the present notice. Like its Kuropean congeners, however, it is so rare, and so remarkable in form, that we have concluded to figure it, and give such a description as the mutilated specimen before us will admit of, in the hope of being able to furnish a more complete one when we shall be so fortunate as to secure more perfect speci- mens. This species is small, longer than broad, the dorsal valve is divided into two very distinctly marked parts, distinguished especially by the direction of the bands and ribs. The visceral portion is slightly arched, and covered with well defined trans- verse bands, separated by somewhat deep furrows, the furrows being ornamented by delicate strize, having the same direction as the bands. The bands are about twenty in number, and appear to reach, all of them, up to the cardinal border on both sides. They are narrower towards the beak, and increase in width, although not regularly, as they approach the front, some of them being more prominent than others. The beak is small; pointed; shows no evidence of a median sinus; and appears to pass little, if any, beyond the cardinal border. The prolongment is cylindrical, and slightly contracted at its junction with the visceral portion ; straight, and in the direction of the axis of the shell. It is covered with broad, regular ribs, numbering about twenty in the space of ten millimetres. The ribs of the prolongment can be traced on to the last fold of the visceral part, giving it a reticulated appearance. Whether the prolongment was closed all round, as in the P. proboscideus, or open on the ventral side, as in the P. genuinus, cannot be decided from the imperfect specimen before us. Dimensions.—Length of the visceral part, 11 millimetres; breadth the same. Diameter of the prolongment, 7 millimetres; length of the part preserved equal to that of the visceral portion. Comparisons and Differences.—It differs from the P. proboscideus of Mr. de Verneuil with which alone it can be confounded, in the longitudinal ribs not extending over the visceral portion, and in the prolongment not showing the numerous and well- marked transverse folds of that species. The longitudinal ribs of the proboscideus are also much finer, numbering about fifty in the space of ten millimetres at the anterior border of the visceral part. Our species shows no trace of a sinus. NORWOOD AND PRATTEN ON PRODUCTI. 11 Geological Position and Locality—This specimen was found by Mr. H. A.

Shell small, transverse, the cardinal edge being the widest part ; somewhat inflated ; but with its visceral and anterior parts rather flattened. Ears very much extended, each bearing, generally, two thick tubes, and are a little enrolled. The surface is 12 NORWOOD AND PRATTEN ON PRODUCTI. — furnished with about thirty tolerably thick ribs. It is difficult to count them, how- ever, in consequence of the shell, which is very thick, being formed of several layers, which exfoliate easily. The beak is small, hardly passing the cardinal border. The visceral part is reticulated by wide, shallow, concentric folds. The dorsal valve is divided by a deep sinus. There are, generally, from six to eight thick tubes seattered over the surface, three or four of which range across the shell in a tolerably straight line, about half way between the visceral portion and the front line of the ventral valve. Ventral valve concave; ribs like those of the other valve, broad and but little raised, while the shallowness of the furrows which separate them rendersit as difficult to number them as those of the opposite valve. The visceral part is crossed by irregular concentric lines. Although the ventral valve is concave over most of its extent, yet, a little before it reaches the opposite one, it suddenly flattens, presenting the appearance of a flat band, which passes around its anterior and lateral borders, This band is a little over one millimetre in width, and is divided from the concavity of the shell by a slightly raised ridge on its interior border. On the visceral portion of the interior of the dorsal valve there is a strong middle projection, on each side of which are the hepatic apophyses, deeply hollowed out in the substance of the shell ; they are triangular, with their anterior part very much ramified. The remainder of the fossil is covered with granular points, which leave corresponding hollows on the internal mould when the shell is taken off. Dimensions.—Length, 18 millimetres; width, measured along the cardinal border, 26 millimetres. The angle formed between the lateral and cardinal borders is 62°. The whole number of ribs is thirty-two. Comparisons and Differences—This species approaches, in many respects, to the P. expansus of De Koninck. It may be easily distinguished from that species, how- ever, by the following characters: the ears of the splendens are rounded, while, according to de Koninck, those of the ezpansus are flattened,—it has several thick tubes on the anterior prolongment, the ezpansus has none,—it has a very thick shell, while that of the ezpansus is thin. When a detached ventral valve can be obtained, the flat border around it will at once distinguish the splendens. Geological Position and Locahties—This beautiful species occurs at Galatia, Illinois, in the coal measures; six miles West of Richmond, Missouri, and near Big Creek, Posey county, Indiana, in a black limestone belonging to the coal measures.

Shell small, transverse ; dorsal valve gibbous, enrolled on itself; beak small, pointed, and not passing the cardinal border. This valve is divided in its middle by a wide, ‘deep sinus. The surface is covered by about forty ribs, some of which, however, after leaving the visceral part, unite, so as to form by their junction one thicker rib; but this character is not constant, as some specimens possess it while others do not. The ears are thin and enrolled; no tubes have yet been discovered on them. The car- dinal border is of about the same breadth as the greatest transverse diameter of the shell. On the surface of the shell itself there are, generally, from six to eight tubes, very thick and long for the size of the shell, one, still attached, being over seven millimetres long. The transverse folds on the visceral disk are wide and shallow, so as to be hardly apparent. The ventral valve is very concave, following nearly the movement of the opposite valve; ribs like those of the dorsal, but it has neither tubes nor hollows. It is furnished with a very decided varix, corresponding to the sinus of the dorsal valve. Dimensions.—Length, 13 millimetres; breadth, 16 mm.; thickness, 6 mm. Ribs.—Forty on the entire surface. Comparisons and Differences—When this shell is entirely disengaged from the rock, it cannot be mistaken for any other species; but when the dorsal valve only is exposed, it may be confounded with the P. splendens ; but even then it may be easily recognized by its much shorter cardinal border. If the specimen has lost its shell, the ribs are still shown on the mould in this species, with a series of rounded hollows along each furrow, between the ribs, while in the splendens the hollows are irregularly distributed over the entire surface of the mould, without any appearance of ribs being shown. The nacre of the shell is still very brilliant. Geological Position and Locality—As yet this species has only been found near New Harmony, Indiana, in the middle part of the Coal Measures.

Cardinal line shorter than the greatest breadth of the shell. ars small, and covered with a great number of small, slender tubercles. ‘The surface of the shell is covered with rather large rounded ribs, which regularly increase in size from the beak to the front in most specimens, while 4 14 NORWOOD AND PRATTEN ON PRODUCTI. on others they are found bifurcating, or with new ribs implanted between the old ores. On the flanks of the shell the ribs are nearly obliterated, but a great number of small spines are seen. A few small spines are, also, scattered over the remainder of the surface. The visceral part is crossed by irregular folds, not so decided as the ribs, but sufficiently well marked to give it a reticulated appearance. The remainder of the surface is covered with fine undulating lines of growth. When the shell is removed, a broad irregular furrow is seen passing round from the front to the ears on each side, and separating the upper portion of the dorsal valve from its anterior pro- longment. Ventral valve very concave ; ribs like those on the dorsal valve, and crossed on the visceral part by shallow concentric folds, a little better marked than those on the opposite valve. ‘The visceral portion is distinctly limited by a large imbricated fold. The ears and flanks are covered with tubercles, similar to those of the other valve. Dimensions.—Length, 20 millimetres. Proportions.—Length, 1.00; breadth, 0.75; thickness, 0.30. Ribs.—On the margin of the transverse furrow, twelve may be counted in the space of ten millimetres. Comparisons and Differences.—This species resembles somewhat the P. fleaistria, but may be distinguished from it by the visceral disk being reticulated, and by the great number of small tubercles with which the surface, especially the flanks, are garnished. Geological Position and Localities. This species occurs abundantly in the Mountain limestone at Chester, and at Kaskaskia, Illinois, and in Missouri, near Hat Island. Explanation of the Figures.—P1.

I., fig. 8, a, b, c. d, e. Shell small; transverse; dorsal valve tolerably regularly vaulted; surface covered with ribs which are rather thick in comparison with the size of the shell. Cardinal border nearly as long as the greatest width of the shell. ars thin and flattened, with six tubes on each. Beak small; not passing the cardinal border. ‘The whole surface is irregularly covered with spines, which project at right angles from the surface of the shell. Visceral disk somewhat flattened and reticulated, the transverse folds being more decided than the ribs themselves, which gives to that portion of the fossil a rugose appearance. Ventral valve concave; its ribs are mostly obliterated by the concentric folds on the visceral portion, beyond which, however, they appear like those on the dorsal valve. On the interior it has a bifid tooth, supported by a median ridge, which NORWOOD AND PRATTEN ON PRODUCTI. 15 extends inwards to the centre of the valve. On each side of this are the hepatic apophyses, small and triangular; by the sides of these are two depressions, and pro- jecting forwards and laterally from these are two large callosities, bounded, anteriorly, by a prominent ridge. On the anterior portion of the visceral disk are several long, obtuse points, inclining forwards, posterior to which the surface is covered by other shorter ones. In front, and along the sides of the visceral disk, are a great number of points imbedded in the shell and looking forwards, but few of which rise above its surface. From near the extremity of the tooth, at a short distance from the cardinal border, proceeds, on each side, a strong and rather sharp ridge, running towards the lateral angles of the shell, but increasing its distance from it as it recedes from the tooth. Just before reaching the lateral edges it changes its direction, bends around with them, and becomes lost, being absorbed by the shell. This ridge, with the front of the shell, presents an oval outline. Dimensions.—Length, 14 millimetres; breadth, 19 mil. Proportions.—Length, 100; breadth, 135; thickness, 0.42. Ribs.—The whole number is from 22 to 24. Comparisons and Differences—By the small number of ribs, the rugose appearance of the visceral disk, and the great number of slender spines, with which its entire surface is garnished, this Productus may be easily distinguished from any other known species. Geological Position and Locahties.—This fossil belongs to the coal measures, and is found in the calcareous clays of that formation. It occurs at Fish-hook creek, Pike county, Illinois, and six miles north-west of Richmond, Missouri. Explanation of the Figures—P\. I., fig. 8, a. View of the dorsal valve of an adult individual.

Shell of a medium size; transverse; dorsal valve gibbous, much enrolled on itself, and divided by a wide deep sinus, originating at a short distance from the beak, and extending to the anterior border. Beak thick and short, not passing the cardinal border. Cardinal border longer than the transverse diameter of the shell. Ears rather long, rounded; follow, in a great degree, the vaulting of the dorsal valve; covered with thick transverse folds; two or three tubes on each.

Surface covered with large ribs, some of which bifurcate near the visceral part; on the anterior portion they unite, two, three, and sometimes four, uniting to form a broad flat surface; but after proceeding in this manner for a short distance, they again separate. On these flat surfaces the striee of growth are well marked. A few thick tubercles are scattered over the surface. Ventral valve un- known. Dimensions.—Length, 24 millimetres. Proportions.—Length, 1.00; breadth, 1.25. Ribs.—On the anterior part, where the ribs are joined together, there are only five in the space of ten millimetres; after they divide again there are ten in the same space. On the visceral disk there are twelve in the same interval, crossed by six of the transverse folds. Comparisons and Differences.—This species approaches very nearly to the P. costatus, but differs from it in several important particulars. The ears of the costatus are sharply detached from the sides of the shell, while in the P. Portlockianus the sides slope gradually down to the cardinal border, and follow in their contour the vault of the dorsal valve. The cardinal border is also longer in our species; and the angle formed by that portion of the shell and the lateral edges is only 85°, while in the costatus it is 100°. It also differs in its ribs, none of which project beyond the others, as they do in that species, but are all flattened alike on the anterior portion. The transverse folds on the visceral portion are also broader than they are in the costatus. Again, the sinus of the Portlockianus is much deeper and narrower than that of the costatus. There is only one other species with which it could be con- founded, the P. Boliviensts ; but it may be at once distinguished from that fossil by the shape of its ears, which are, in the Boliviensis, more abruptly separated from the sides than in any other known species of the genus; and by its beak passing far over the cardinal border, while in the Portlockianus it scarcely overlooks it. Geological Position and Localities.—We have only met with two specimens of this species; one at Grayville, White county, Illinois, and the other at Charboniere, St. Louis county, Missouri. They both occur in the coal measures. Explanation of the Figures.—PIl. I1., fig. 9, a. View of the dorsal valve. Fig. 9, 6.

When placed on its ventral valve, presents a rectangular form. Cardinal line equal to the greatest breadth of the shell. The ears are much extended, and garnished with a double row of tubes, very large in propor- tion to the size of the shell; those nearest the cardinal border being directed back- wards, and projecting far beyond the edge, while those in the second rank point 1m- mediately upwards. The ears are covered with large folds. On the visceral portion a few irregular undulations occur, none of which traverse it entirely. Dorsal valve tolerably regularly arched; its anterior part flattened, sometimes depressed in the middle, and then showing a wide, shallow sinus. The sides slope very gradually down to the ears. The beak is small, rather pointed, and passes the cardinal border. The surface is covered with a great number of longitudinal ribs, regular in form, and increasing by the implantation of new ones. From twenty to thirty tubes are scattered over the surface; the remains of which show them to have been very long in proportion to the size of the shell. They all project from the shell at nearly right . angles to their attachment, but, after proceeding a short distance, bend downwards. The anterior prolongment is broken off on every specimen in our possession, with the exception of a small fragment on the flank of one. This fragment passes about ten millimetres beyond the visceral disk of the ventral valve. Ventral valve concave, the visceral disk being divided from the ears by a very large fold, with a deep hollow between this fold and the cardinal border. On this valve there are neither tubercles nor hollows; its ribs are like those of the dorsal valve. Outside of the visceral disk the shell is traversed by three or four wide imbricated folds. On the interior of the ventral valve there is a small bifid tooth, with a rounded hollow at its base, from which projects a very slender ridge, which crosses about one third of the valve. Dimensions.—Length, 20 millimetres. Comparison.—Length, 100; breadth, 130; thickness, 0.35. 5 18 NORWOOD AND PRATTEN ON PRODUCTI. Ribs.—At the distance of ten millimetres from the beak there are eighteen in -the space of ten millimetres. Relations and Differences.—This shell may be readily distinguished from the P. Villiersi, to which it bears resemblance, by its visceral part being less enrolled ; in having a more depressed form; in the great extent of its ears; in its beak being smaller and more pointed; and in its tubes projecting more directly out from the shell, instead of proceeding downwards in their attachment, as they do in the P. Villierst. Geological Position and Locality—This species is supposed to belong to the coal measures; it is not, however, absolutely determined. It was obtained by Mr. H. Pratten at the crossing of the Big Nemahaw river, about 85 miles a little North of West from St. Joseph, Missouri. Explanation of the figures.—Pl. L., fig. 10, a.

Note.—It affords me great pleasure to be able to dedicate this new and beautiful species to my friend and fellow laborer, Mr. H. Pratten; to whose quiet but fruitful labors, for many years, several branches of science, besides geology, are largely indebted. J.G.N. P. HILpRETHIANUS, nob.—PI. L., fig. 11, a, 6, e. Shell of medium size; depressed; transverse; subtriangular. Surface covered with moderately-sized, rounded ribs, the furrows between which are wider than the ribs themselves. The ribs are increased both by bifurcation and the implantation of new ones. The front is flattened, with a very wide but shallow sinus. Beak small, - pointed, passing beyond the cardinal border, which appears to have been short; in the only specimen found, however, the cardinal border is unfortunately broken off, on both sides, at about six millimetres from the beak, so that we have little of the ears remaining. The sides fall almost perpendicularly on to the ears. The ears and flanks are covered with a great number of small, slender tubercles. The whole sur- face of the shell appears to have been covered with tubercles, which have fallen off, in the specimen before us, leaving scarcely a mark of their place of attachment. We infer, from this, that they fell off during the life of the animal, as it is difficult to see the cicatrices without the aid of a good lens. There are no concentric folds; but the entire surface is covered with fine undulating strize of growth. Anterior prolongment, if any, unknown. NORWOOD AND PRATTEN ON PRODUCTI. 19 On the ventral valve, the ribs appear to radiate from the beak. In the first part of their course they frequently bifurcate ; afterwards few of them do so. ‘They go on, however, regularly increasing in size, down to the margin; and are covered with a great number of elongated tubes, lying closely down on the shell. This valve is a little concave, with a slightly raised varix opposite the sinus of the dorsal valve. Dimensions.—Length, 28 millimetres. Comparison.—Length, 100; breadth, 111; thickness, 0.40. Ribs.—At twenty millimetres from the beak there are ten in the space of ten mil- limetres. Comparison and Differences—We know of no Productus that can be confounded with this species. Its flattened and triangular form, the greatest breadth being near the front margin, from which it regularly decreases to the beak, as well as the great number of spines on the ventral valve, will at once distinguish it from all others. Geological Position and Locality.—It occurs in nodules of black limestone, imbedded in a coal seam, at Charboniere, Missouri. Explanation of the figures.—Pl. I., fig. 11, a. Dorsal aspect.

Shell of medium size; length and breadth about the same. In young specimens the dorsal valve is tolerably regularly arched, but is flattened on its anterior part, without showing, however, any anterior prolongment; when old, it has a decided anterior prolongment, proceeding at right angles from the visceral portion. The old specimens have, also, a wide but shallow sinus. The surface is covered with wide, flattened, transverse bands, placed one above the other, like tiles on a roof. These bands are covered with spines, of which every eighth one reaches from the lower edge of the band above to the lower edge of its own band. Midway between these are other spines, which only reach half way up the band; and, between these again, are others, which are only half the length of those last mentioned ; and, finally, between the latter come out small tubes or. points, which are planted immediately on the lower edge of the band. Some of these tubes are from five to eight millimetres in length, and project downwards close tothe shell, forming a fringe around the lower edge of each band. Beak small and passing beyond the cardinal border. Lars small and a little enrolled. Ventral valve almost unknown. We have only one specimen which shows any portion of it, and that exhibits only a fraction of the internal surface. It is never- theless, sufficient to show that this valve possessed bands like those of the dorsal valve, that it followed all its movements, and that its visceral disk approached very near to that of the other valve, there not being a distance of four millimetres between them. Its internal surface is pitted with small hollows, corresponding to the tubes of the dorsal valve. Dimensions.—Length, 28 millimetres. Comparison.—lLength, 100; breadth, 100; thickness, 0.14. Bands.—On an old specimen the whole number of bands are fifteen. At ten mil- limetres from the beak there are three bands in the space of ten millimetres. Comparisons and Differences—This shell differs from the P. punctatus in being smaller : in its broader and more regular bands; in the arrangement of the spines on the bands; in its flattened anterior prolongment; and, especially, by the close approximation of the two valves. Geological Position and Locality.—Found in the mountain limestone, at Rocky run, Hancock county, Illinois. Rare. Explanation of the Figures.— Pl. IL., fig. 1, a.

Il.—WNotice of the genus CHONETES, as found in the Western States and Territories with descriptions of eleven new species. By JoserpH G. Norwoop and Henry PRATTEN, of the Hlinois Geological Survey. This genus was established by FiscuEr in 1837, to separate from the genus Lepteena such shells, having the same general form with those of DALMAN’S genus, as possess a row of spines of the margin of the dorsal valve along the cardinal area. At that time there were six species known. Up to the year 1843, other species were added by European Geologists; and, in that year, our most distinguished paleontologist, Professor HAut, described two from this country, C. cornuta and C. setigera, which he united to the genus Strophomena of RArinEsquE. In 1847 M. pe Konincx published his excellent Monograph on the genus, in which he not only enumerated, but described every known species, amounting, in all, to twenty-three, including all those known in this country. Since then, in 1852, Dr. D. D. Owen described a new species from Missouri, making all the known published species, up to the present time, amount to twenty-four. The two species already mentioned as described by Prof. Haut, belong to New York; the third one, described by M. pe Konincx, the C. Shumardiana, is from Kentucky, and named by him in honor of the zealous geologist and paleeontologist who discovered it. We now make known eleven new species from our Western States and Territories, and announce the discovery of two others of the known species of Hurope in our western formations, viz: C. armata, of M. BoucHarp, and C. Sarcinulata, of ScunorHEnt. Six of these species were found at a single locality, the “Devils Backbone,” in Tllinois, in limestone belonging to the Devonian period; one, two miles west of Jones- boro, Illinois, in limestone of the same age; two, in the Mountain limestone of Burlington, lowa; four are from the coal measures; and one, the Flemingii, is from a formation, the age of which has not yet been determined, but which, probably, belongs to the Coal period. It was found by Mr. Pratten ten miles northwest of Richmond, Missouri. The whole number of species known to M. pr Konincx, in 1847, 23 Added by Dr. D. D. Own, (U.S. Geological Survey,) 1 Addition made now, el: Making the present number known, 30 Seventeen of these species occur in the Western Sites of oes yh Re To these add the two species found in New York, and we have nineteen species found in 24 > NORWOOD AND PRATTEN ON CHONETES. our country, four of which are common to the United States and Europe; and fifteen, as at present known, peculiar to this continent. We must say, however, that there is still another species, brought from the Humboldt river, in Utah, the markings of which are too much obliterated to admit of its being described. It belongs to the Mountain limestone, and is, from its form, evidently distinct from any other one of our species. It was found by Mr. Pratten. Genus CHONETES, [ischer. C.

The entire surface is covered with small pits or hollows, as if from the falling off of tubes or spines; these pits are tolerably regularly disposed in quincunx; they are always on the summit of the ribs, and are larger and altogether different in shape from the hollows at the bottom of the furrows between the ribs; these latter being merely fine lines as if drawn by the most delicate graver. It has a wide shallow sinus, which originates at the beak, and goes on increasing in breadth to the front. The area is very large and formed by both valves ; the portion belonging to the dorsal valve being hollowed, while that of the ventral valve is flattened. The deltoid aperture is wide but nearly filled by the tooth of the ventral valve. Lars distinctly separated from the dorsal vault by a wide depression. The cardinal edge has ten tubes on each side of the beak. The ornaments of the ventral valve are like those of the opposite one. On the internal surface of the ventral valve there is a bifid median tooth resting in a socket, and supported by five ridges projecting into the shell, the two largest of which are nearly parallel to the cardinal border; at a small distance from it, the cen- tral ridge projects about two fifths across the valve; on each side of this are two others supporting a series of points. All the interior surface, but particularly towards the front, is covered with small points. NORWOOD AND PRATTEN ON CHONETES. , 25 Dimensions.—Leneth, 15 millimetres; breadth, 22.

Shell of medium size; transverse, having its greatest breadth at about one third the distance between the cardinal border and the front margin. Dorsal valve slightly but regularly convex. ars not separated by a depression from the dorsal vault. It has no ribs, properly so called, but in place of them the surface is covered with an innu- merable quantity of extremely fine strie, which radiate from the beak. These striz are crossed by concentric ones equally fine, giving it the appearance of fine net work. There are five long thick tubes on each side of the beak, which project in nearly straight lines backwards from the shell. Area and ventral valve unknown.

Shell rather small; depressed; transverse, having its greatest breadth on the car- dinal border. Dorsal valve covered with a great number of slender, filiform ribs, which frequently bifurcate and amount, when they reach the free borders of the shell, to about 150. It is provided with a tolerably deep and wide sinus. The area is formed at the expense of both valves. Deltoid aperture rather wide. LHars some- what flattened, and separated from the dorsal vault by a very decided depression. Cardinal edge ornamented by seven tubes on each side of the beak, which are directed obliquely. In the furrows between the ribs are numerous shallow depressions, as represented in the magnified view of a portion of the shell, Pl. IL, fig. 6,¢. The ventral valve is furnished with a varix, corresponding to the sinus of the opposite one. Its ribs are like those of the other valve, but become obliterated on the ears. Internal part of the dorsal valve—There is a strong ridge projecting from the beak towards the middle of the shell; on each side of which there is a large and deep depression. Most of the remaining surface is covered with large granulations, which, however, stop short of the free margin of the shell. Around this may be seen a series of ribs corresponding to the furrows between the exterior ribs, and showing a series of fine granulations, which answer to the small depressions of the exterior. , Dimensions.—Length, 10 millimetres ; breadth, 17. Geological Position and Locality—It is found in beds of shale, ten miles North West of Richmond, Missouri. The age of the beds has not yet been determined. Explanation of the Figures.—P1.

It is small, transverse, having its greatest breadth on the cardinal border. Its beak is much larger and higher than that of any of our other Chonetes. An extremely deep sinus extends from the beak, bordered on each side by a high ridge; outside of which there is another sinus separating the ridges from the ears, which are a little rounded and much extended. Its surface is covered with about 100 ribs, very fine and dichoto- mous. Area tolerably large, and formed at the expense of both valves. Deltoid aperture very wide. Cardinal edge with four tubes on each ear, directed obliquely. The ventral valve is furnished with a very decided varix, corresponding to the sinus of the opposite valve. Its ribs are like those of the dorsal valve. . Dimensions.—Length, 7 millimetres; breadth, 12. bo ~I NORWOOD AND PRATTEN ON CHONETES. Comparisons and Differences—The depth of the sinus and the height of the ridges alongside of it, will at once distinguish it from all other species. It is true that, while young, it may be mistaken for the C. Flemingii; but even then its sinus is deeper than in that species, and it has only four spines on the cardinal edge on each side of the beak, while the Flemingti has seven. Geological Position and Locality—This species occurs at Charboniere, Missouri, in the calcareous clays of the coal measures. We dedicate this species to M. de Verneuil. It will at once recall to every one the Productus, which bears his name, as they are both possessed of a remarkably deep sinus. Illinois State Collection. Explanation of the Figures.—P1.

Shell small; transverse, sub-rectangular. Dorsal valve covered with extremely fine ribs, which, on the margin, number 150. They are everywhere crossed by equally fine concentric stris. This valve is furnished with a very wide median sinus, ~ originating near the beak, from which it goes on increasing in width to the front margin. From the bottom of this sinus rises a rounded fold of the same shape as the sinus itself; that is, it is pomted towards the beak, widening from thence to the front, so that its outline is triangular, the base being at the front of the shell. ars small, and separated from the dorsal vault by a well marked depression, giving to the front of the shell the appearance of being formed of three lobes, separated from one another by the median sinus. Area rather large, and formed from both valves. Deltoid aperture nearly closed by the tooth of the ventral valve. The cardinal edge bears seven oblique spines on each side of the beak. Ventral Valve——Its ribs are like those of the other valve. It has a well defined middle sinus corresponding to the raised fold of the dorsal valve. On each side of this sinus it has a sharp fold opposite to the bottom of the sinus of that valve. Dimensions.—Length, 8 millimetres ; breadth, 11. Comparisons and Differences.—At present there is no species of Chonetes known, with which this one can be confounded ; no other one having a medial fold rising from the bottom of the sinus of the dorsal valve. .

Shell somewhat large ; depressed; transverse, having its greatest breadth near its middle. At five millimetres from the beak the ribs number about thirty ; at one third of the distance from the beak to the margin, most of them bifurcate. Between this and the margin several of them divide again, and when they reach it, they number about one hundred. The furrows between the ribs are of the same size as the ribs themselves. On the internal mould of the dorsal valve, the central furrow is larger than those on the right and left of it, evidently caused by a median tooth, which, commencing at the cardinal edge, traverses more than two-thirds of the length of the shell. On each side of the beak there are eight spines, directed obliquely. The ven- tral valve is slightly concave. Its surface is similar to that of the opposite one. Dimensions.—Length, 22 millimetres; breadth, 32. ; Geological Position and Locality.—This species was found at the “ Devil’s Backbone,” Illinois, in limestones of the Devonian period.

Shell of medium size; depressed ; transverse ; sub-quadrangular ; the cardinal border being, in a slight degree, the broadest portion of the shell. Dorsal valve somewhat convex, and covered with tolerably large ribs, which bifurcate two or three times before attaining the margin, where the whole number amounts to eighty. It has a wide but shallow sinus, which originates near the beak, and gradually widens as it proceeds towards the front. Lars flattened. Areaunknown. The cardinal edge has eight thick blunt tubes on each side of the beak. The ribs of the ventral valve are like those of the opposite one. On its internal surface it has a cardinal tooth supported on four plates, which project inwardly, and appear to be formed by the union of several ribs. The two plates nearest the cardinal edge are much the largest. The internal ribs, which correspond to the external fur- rows, show a series of granulations, but they are farther apart than in most of the species of the genus. Dimensions.—Length, 22 millimetres; breadth, 25. Ftibs.—There are, on the margin, eleven in the space of five millimetres. Comparisons and Differences.—This species differs from the C. Maclurea in its more quadrangular shape, in the smaller number of its ribs, and in the possession of a sinus, (that species having none.) From the Zuomyi it differs in its sinus, in the greater number of its ribs, and in having eight tubes on each side of the beak, while the Tuomyt has but six.

Remarks.—This serpent has the general characters of coronella, but the nos- trils open between the anterior frontal and nasal plates, instead of the nasal and in- ternasal, the two being fused into one plate.

This specimen was recently brought from Honduras by my friend Dr. Samuel Woodhouse. One is at once struck with the beauty of this serpent. In its general appearance it resembles somewhat the Zamenis viridi-flavus, of which we have a very fine specimen in the Academy, found by me in the Pyrenees,—but their great dissimilarity is readily observed on placing the animals in juxtaposition. The markings of the head and sides are altogether different ; in viridi-flavus the eye rests upon the fourth and fifth labials, and not upon the fifth and sixth, but the number of plates about the head is nearly the same, and there is no great variation in the form. * Proceed, Acad.

Folia subamplexicaulia, elongato-cordata, valde repando-sinuata undulata. Flores in apicibus 3-4 conferti, breviter divaricateque pedunculati. Calyx 3-sepalus caducus setosus, quoque sepalo cornuto, cornu in aculeum validum desinente. Corolla 6-petala maxima, 5-4’ diametro; petalis cuneato-obovatis, mar- gine denticulatis, albis recte venosis. Germen lanceolato-cylindricum, aculeis rectis dense obtectum. Capsula adhuc ignota. Stem branching, about 22 feet high. The whole plant very glaucous and, chiefly on the stems and margins of the leaves, densely covered with strong and slightly retrorse prickles. Leaves subclasping, elongate-cordate, deeply repando-sinuate and undulate. Flowers in clusters of 3-4 on short divaricate peduncles. Calyx 3-sepa- lous, prickly, each sepal bearing a horn terminating in a strong prickle. Corolla 3—4’’ in diameter ; petals six, white, veined, with slightly denticulate margins. Germ lan- ceolate, cylindrical, densely covered with erect prickles. Capsule unknown. The specimens submitted to our examination are incomplete and not sufficiently advanced to determine the shape of the mature capsule and seeds. We have com- pared it with various forms of A. mexicana and with the figure of Lindley’s A. gran- diflora in Bot. Reg. T. 1264. If the latter and our plant are but varieties of A. meai- cana, as Prof. Asa Gray thinks, they are two extreme forms of this very variable species, the one being almost unarmed and the other densely prickly. Both Lindley’s and our plant bear large and beautiful white flowers; but-in ours the texture is more delicate than in the mexicana, and the habitus of the leaves and branches is less acute, more rounded and undulating; the peduncles are shorter, stouter and more divaricate. It grows in large patches at Williamson’s Pass and was in full bloom in August and September. * Tc be republished, with figures, in Lieut. R. S. Williamson’s Report. 10 38 PLANT/E HEERMANNIAN &.

They gradually grow to four times the primitive size, and as they grow, the narrower ex- tremity lengthens into a kind of beak, or rostrum, which bears the two flagels. This rostrum is always transparent, empty, and is incapable of any kind of motion. Fig. 7. The whole cell has a pyriform appearance. It has, from the first period of its existence, secreted an external transparent delicate membrane, which widens and expands every hour, Fig 8. This outer covering seems to be of a gelatinous or semifluid amorphous nature (probably gelatinous gelin). As this outer membrane developes itself it gradually encloses the flagelliform appendages, and proportionately slackens their motions, so as at last to stop these altogether, Fig. 9. These cells are the gonidia of some botanists, the macrogonidia of Braun. By degrees the red matter in these gonidia concentrates around their central nucleus, and the outer paler zone acquires a green color. In this green portion (gela- | tinous chlorophyll) may be seen, 2, 3, 4, 5, or 6, larger amylon grains, besides smaller specks of the same substance mixed with minute drops of oil, and still minuter par- ticles of globulinar chlorophyll. Fig. 10. These cells, if submitted to the ordinary tests, (iodine and sulphuric acid) show that the outer wide membrane is composed of gelin, the quite interior one which is closely applied to the inner surface of the latter being protoplasma (protein substance). The internal green chloryphyll remain unaltered by the tests, but the red portion seems to divide into a number of separate globules, which acquire a deeper and more intense coloring, indicating the presence of protein substance, probably mixed with some oily or waxy compound and some peculiar coloring substance. The coloring matter is soluble in rectified oil of turpentine and in ether, and is, perhaps, a mixture of Erythrophyll and Xanthophyll. These two substances have been proved by Mulder and by Kiitzing to be formed by the disoxygenation of the chlorophyll under the influence of strong light, of cold, and of other causes. The coloring matter of the Chlamidococcus differs from all other red coloring matters in plants (known to me) by its not being turned blue by the action of alkalies. The chemical structure of the outer coverings of these adult gonidia show that these cells of Chlamidococcus differ considerably from the swimming spores of many other algee, which I believe to be (as asserted by Kiitzing, Grundziige der philosophi- schen Botanik, p. 295) in nearly all cases, formed externally by an unprotected pro- tein membrane, which it is easy to distinguish from the bassorin cell membrane of the parenchym cells of many cryptogamia by boiling with nitric acid and adding ammonia. Hach of the first gonidia (cells of the first swimming generation, or cells of tertiary formation) finally becomes stationary, the outer gelin covering hindering all further motions of its flagels. These now disappear, being seemingly re-absorbed into the general coating of protoplasma. The wide outer covering remains unaltered. The OF THE STATE OF GEORGIA. 63 larger amylon grains which, until now, had been distinct, disappear. Fig. 11. Between midnight and morning a longitudinal division of the cell takes place, which divides it into two fixed, immovable cells (cells of quaternary formation.) Fig. 12,a. Very shortly after this (one or two hours after) these last formed cells are each in their turn seen to subdivide into two active gonidia furnished with flagelliform appendages. Fig. 12, 6. These last (cells of quinary formation) move actively even before leaving the envelop of the mother cell, but before dawn finally break through it. They then — live the same independent lives that the first swimming gonidia had led, and go on moving actively for two or three days. This,second generation of flagel-bearing gonidia differs from the first only in being green from the onset, each cell having at its birth and ever afterwards a small, red, central mass; whereas, be it remembered, the first generation of active gonidia were red at first, and only acquired a green color some time after their liberation from the mother cell. Figs. 13, 14. After a period of from 48 to 72 hours (and always during the hours of darkness,) the second generation of motive gonidia each separate into two immovable cells, (6th formation, Fig. 16,) each of which in their turn divide into two new motive gonidia, (gonidia of third generation, 7th cell formation. Fig. 17.) This takes place in exactly the same manner as in the preceding generation, and this multiplication goes on iden- tically and uninterruptedly for a period of about six weeks, producing in that space of time from twelve to nineteen successive generations of motive gonidia. The latter formed generations often differ somewhat from the first in having the central red spot nearly obsolete or altogether wanting; (fig. 18,) and in some cases as first seen by Von Flotow, in containing large internal hollow spaces, which displace the green lining of gelatinous chlorophyll, giving a lacunose appearance to the cell. Fig. 19. These internal vacuoles sometimes displace the central red mass, and render it parietal, so as to make it resemble an eye, and give to Chlamidococcus the appear- ance of a Chlamidomonas. Fig. 20. The green gonidia are very sensible to light, they collect in greater numbers in that part of the vase they are held in, which receives the sun’s rays. Their respiration is identical with that of other green plants, i. e., they disengage oxygen during the day and carbonic acid during the night. This fact was noticed by Ehrenberg with respect to Chlamidomonas, without his suspecting, however, its vegetable nature, as he describes it as having eggs, an eye and a testicle, which are nothing else than the grains of amylon, the red mass, and the cytoblast we have spoken of above, and which exist as well in Chlamidomonas as in Chlamido- coccus. Hach of the gonidia of the 19th or last of the motive generations, gives birth to two immovable green cells, each of which shortly after is in its turn divided into two other cells, but which, differently from what has been taking place in all the pre- ceding generations, are unproductive of a new generation of cells. 64 DEBY’S RESEARCHES ON THE CRYPTOGAMIC FLORA These last cells soon take a rounded form, become immovable, attain gradually their full size, absorb their flagelliform appendages, lose their wide outer membrane, cover themselves with a tenaceous and thick cell membrane, turn gradually to yellowish, then to red, or to a brownish-red hue, and now all organic functions seem to lie dormant in them for awhile. Fig. 21. If these red cells be submitted to the action of iodine and sulphuric acid, they again take a green color. I attribute this to the fact that the gelin coating is turned blue and the protein coating yellow by these tests, the combination of which two colors forms green, but this is only hypothetical. In some accidental cases the last generations of gonidia, instead of following the above mentioned order of phenomena, divide rapidly into 2, 4, 8, 16, 32 smaller gonidia, which are at first aggregate inside the mother cell which has produced them. (Fig. 22.) They, however, ultimately break loose and swim about freely for some time, without seeming either to grow larger or to produce new cells. These are the Micro- gonidia of Alex. Braun; they vary from ;;; to 5; of a millimetre in diameter, have two flagelliform appendages, are of a yellowish or yellowish-green color, and have the rostrum slightly reddish. Fig. 23. The larger fixed red cells formed by the last (19th) generation of gonidia remain dormant for an indefinite period if left in water. They even seem to die and decompose if left there for a great length of time. But if the water they are contained in be slowly evaporated to dryness in the sun, be it only for a few hours, and fresh water be poured over them, new life is soon manifested, and generally by the next morning fresh gonidia (of primary generation) will be found fully developed and swimming actively about. These will go through the whole series of vegetative phenomena we have above described, and prepare a future generation of fixed cells, destined in their turn to perpetuate indefinitely the existence of this species of plant. If, instead of immersing the immovable, dormant red cells in water, we simply keep them in a state of dampness for some hours, they will generally divide into two fixed cells (of secondary formation), these in turn will divide into four (of tertiary formation and corresponding with the first generation of appendiculated gonidia) fixed, globular, unappendaged cells; then again into two (quaternary), then, last, into two (quinary) others, and so on for a considerable period of time, which I have not followed out, but which is, most hkely dependant upon temperature and the quantity of water furnished. These cells rarely attain above half the size of the primitive mother cell, they are generally globular, of a reddish-brown color, and always destitute of flagelliform ap- pendages. In the same way that the last swimming gonidia return to the form and nature of the parent cell—so do the last generations of this abnormal form of Chlamidococcus also produce larger cells of a thicker and darker color, which cannot be distinguished OF THE STATE OF GEORGIA. 65 from the primitive mother cell, and which, after desiccation, are also capable of repro- ducing all the above described series of phenomena; on which account they must be considered as identical in functions and nature. In the last named form of Chlamidococcus, in which none of the cells are motive, the wide, outer membrane, which in the normal type envelopes each gonidia, is also secreted, but the divers cells being very close to one another, the consequence is that this gelatinous matter finally forms an apparently continuous amorphous crust of a pale yellowish color, in which the successive generations of cells are immersed. Chlamidococcus is now indistinguishable, by a cursory examination, from the genus Pleurococcus, Fig. 24. Braun, who has noticed these two modes of growth, noticed also that in the last described form, the production of 4, 8, 16, 32, &c., microgonidia took place occasionally just as described in the more perfect form of Chlamidococcus, but these microgonidia are globular and unappendaged, Fig. 29. I believe that in both cases the production of microgonidia must be attributed to quite accidental causes, such as a diseased state of the producing cell, a peculiar tenacity of its outer membranes, or an over-excited formative power brought on by unknown causes. If this were not the case these microgonidia would not die away without producing fur- ther generations or acquiring the ultimate dimensions of macrogonidia, which they are never known to do. CONCLUSIONS. The curious vegetation of Chlamidococcus above described may be understood in two different ways : 1. We may imagine every cell, (be it primitive mother cell or motive gonidia) as a spore, or complete individual plant, and admit that as in the lower classes of animals we have here “ alternations of generations.” By changing the word animal into the word plant, Steenstrup’s description of this singular fact would read as follows: “ Alternation of generations, or the remarkable phenomenon of a plant producing offspring, which at no time resembles its parent, but which, on the other hand, brings forth a progeny, which returns in itsform and nature to the parent, so that the maternal plant does not meet with its resemblance in its own brood, but in the descendants of the second, third, fourth or(. . . nth) degree of generation; and this always takes place in the different plants which exhibit the phenomenon, in a determinate genera- tion, or with the intervention of a determinate number of generations, &c.” (See J. J. Steenstrup, Altern. of Gener., translated by George Busk, 1845, Ray Society.) Now, in Chlamidococcus, we may suppose we have a primitive plant (first red, fixed cell) producing an offspring (motive gonidia) which at no time resembles the parent, but brings forth a progeny which returns (after several generations) im its form and nature, to the parent cell, so that the maternal Chlamidococcus does not meet its resemblance in 17 66 DEBY’S RESEARCHES ON THE CRYPTOGAMIC FLORA. its own brood, but in its descendants of the 14th or 15th compound generation. We might carry on this comparison much further, but as we believe it to be a simple analogy with the facts stated by Steenstrup as existing in the Meduse, Polypes, Corallines, &c., and no identity, we prefer not prolonging here what we consider to be useless and sterile discussion, and we shall at once pass to the second manner of in- vestigating the matter, which seems more consistent with philosophical induction as applied to Algology. 2. All plants are produced by the multiplication of a simple cell, which in the cryptogamia is called a spore. If we follow out the subsequent development of such a spore, we observe it generally to produce a succession of vegetative cells (not spores), until having at last attained maturity, (having produced a determined number of such cells) it forms one or several peculiar cells of a different nature from the antece- dent one. These last are the real spores destined to produce a new succession of vegetative cells, and after these a second generation of spores. The cells formed ante- riorly to the spores are generally connected together by cohesive or intercellular sub- stance, so as to form a parenchymatous mass, or thallus. The formation and deposi- tion of cells may take place according to three dimensions of space. It may take place in length (in a linear direction), and we have a filamentous (articulated) thallus, as in Conferva, Zygnema, &c. It may take place in length and in breadth simulta- neously, and we have a foliaceous thallus, as in the Ulvace, &c.; or, lastly, it may take place in length, breadth, and height (thickness) at the same time, and we obtain a massive parenchymatous thallus, which may be regular or irregular. In the development of Chlamidococcus in a damp place, or when kept humid, as above described, we have an exemplification of an alga produced by an ordinary spore, and consisting in an irregular foliaceous thallus, which, after growing for a determined time (by production of new vegetative cells) dies away, all but the last formed spores, which remain dormant until called into life by external circumstances. May we not consider also the development of the Chlamidococcus, immersed in water, as a growing plant, in which the ordinary vegetative cells are free (instead of being united into a so-called compact thallus) andin which the terminal or last formed cells, just as in other algze, end by giving birth to spores? I think analogy and mor- phological considerations lead to the adoption of this manner of viewing the subject. In fixed alge the cells are immovable, and united to one another in the thallus; in the form under consideration they differ only in being free and being furnished with prolongations of the inner cell membrane, which give them for a short period limited locomotive powers. In the crustaceous form of Chlamidococcus, where these flagel- liform organs would be useless, we find them to be wanting, and yet the plant is fertile that is, bears at last well-formed spores at the surface of its thallus, so that we may consider these curious appendages of very secondary importance in the organic OF THE STATE OF GEORGIA. 67 economy of this plant. According to the above expressed views I would define ,Chlamidococcus as a plant formed by a successiwely deliquescent and evanescent thallus, each vegetative cell of which is free, 1s endowed with an independent motion (produced by two lengthened flagelliform appendages) and has an independent life. Kach new gene- ration of four cells being accompanied by the destruction of the precedingly formed part of the thallus which has produced it. The terminal (or last formed) cells of this vague thallus produce globular, fixed, unappendaged red spores. These spores con- tain from two to six large grains of amylon and acentral cytoblast. The fully developed evanescent parenchym ? cells of the thallus? are green, with a red central - (not parietal) mass, in the middle of which is situated the cell nucleus. In an aberrant form this alga constitutes a continuous, non-evanescent thallus, in which the cells are globular, unappendiculated, and united by an amorphous inter- cellular substance. This discoid thallus produces at its periphery (surface), spores identical with those generated by the typical form. I believe the above definition to be consistent with the strictest laws of analogy, as applied to the morphology of the lower plants ; if I have erred, I shall be sufficiently rewarded for my labors if I should have attracted the attention of other naturalists, and induced them to take up the study of this interesting branch of natural history. Linnzus has said, “ Nullus character infallibilis est ;” but however little encouraging this maxim may seem, it must not dishearten nature’s votary, who can only describe things to the best of his abilities, in a way concordant with the present state of science, and who must ever remember that perfection is the attribute of the Creator, not of the creature, and that human science is only a very small, fragmentary, shape- less particle of Omniscience, which last is beyond his reach. oH ay fi xvi ue he ot off rine ree ve a ) sts we Nie’ Slpka lasts ok We Mew cosine OE Te yh ee ty oh ahi ve My 4 - ps ; vot at TERE ot { is ait pies sive a = ‘ ag Ae ae a zt ; ye bias - ue HS ee AY r weed i ay.

By Josepu G. Norwoop and Henry Prarren, of the Illinois Geological Survey. SPIRIFER, S. sprnosus, nob.—Plate IX. fig. 1, a, 6, 6 d. Shell rather small. Both valves very convex. The dorsal valve bears five or six rounded ribs on each side of the sinus. The ventral valve has four, and sometimes five, similar ribs on each side the central lobe. The lobe itself vesembles a large rib, being only-about double the size of those next to it on each side. The other ribs eradually diminish in size as they approach the cardinal border. They are covered with large and deep but irregular striz: of growth, which are most numerous near the margin. Besides these large imbricated striae some of the most perfect specimens are beautifully marked with finer concentric striz, visible only by the aid of a lens. The surface of the shell is irregularly covered with short, hollow spines, projecting at nearly right angles from their bases. On all the specimens yet met with the spines are broken, the longest fragments measuring about one-sixteenth of an inch. In addition to these spines, the whole shell, including the cardinal area, is covered with minute granules. Where these are rubbed off there is the appearance of small open- ings into the shell, giving it the aspect, somewhat, of being covered with a minute coral. Cardinal area, triangular; high ; a little shorter than the greatest breadth of the shell, and having sharp edges on the ventral valve only. The median slit is large and open, and occupies about one third of the space left free from the encroachment of the ribs of the dorsal valve. Dimensions.—Length, six tenths of an inch ; breadth, eight tenths. Comparisons and Differences.—This shell has nearly the form of the S. octoplicatus, of Sowerby, but differs in having fewer ribs; in the sinus of the dorsal valve being wide and rounded at its bottom; and also in all its ribs being rounded. When the epidermis is well preserved, the spines with which it is covered will readily distinguish it from all other species. . Geological Position and Localities.—This species occurs near the top of the mountain limestone, associated with Pentremites sulcatus, pyriformis, and florealis, Prodwctus 19 I bo NORWOOD AND PRATTEN, NOTICE OF FOSSILS FROM THE elegans, and Spirifer Fisherianus.

Lerpy1, nob.—Plate IX. fig. 2, a, 6, ¢. Shell of medium size; extremely variable in form, some specimens being globose, while others are rather flattened. In young specimens the cardinal border is equal to the greatest breadth of the shell; in old ones the greatest breadth is towards the middle. The dorsal valve is furnished with a sinus, having sharp borders. It reaches to the beak, and opens under an angle of 16°. ‘There is one tolerably large rib at the bottom of the sinus, and on each side of it we find another, which is rather flattened, and placed like a step about midway from the middle rib to the top of rib bordering the sinus. On either side of this the ribs number from six to eight. Sometimes there are six or eight on one side and seven on the other. The varix of the ventral valve is strongly projected above the rest of the shell, although its height is diminished by a furrow which corresponds to the rib found at the bottom of the sinus of the other valve. On the sides of the varix there are step-like projections, similar to those found on the sides of the sinus. On a few specimens, however, these ribs are wanting on one side, but are never altogether absent. On each side of the varix there are from six to eight rounded ribs, similar to those on the dorsal valve. The ribs on both valves project strongly. Some of the specimens are beautifully marked, especially toward the front margin of the shell, by imbricating lines of increment. These are disposed in such a manner as to show that the shell increased faster in length than it did in breadth. Other individuals are entirely destitute of these markings. On all well preserved specimens the surface is covered with fine strize, only to be discovered un‘ler the lens. Some of these striz are parallel to the ribs, and others to the free borders of the shell, so that they cross each other, forming a kind of net-work. Those radiating from the beak are rather more prominent than the others. The cardinal area is of moderate height and triangular, the angle being 152°. It is covered with perpendicular and transverse strize. Deltoid aperture open, and of medium size. Dimensions.—Length, eight tenths of an inch; breadth, one inch. Comparisons and Differences——This species comes nearest to the 8. acuticostatus of De Koninck, but differs in its ribs, which are rounded, while those of the acuticostatus are sharp. The supplementary ribs on the sinus and varix will, however, at once distinguish it from that species. It is also a larger shell.

Shell of medium size; its greatest breadth being along the cardinal line. Dorsal valve rather more gibbous than the ventral, and furnished with a very shallow sinus, hardly amounting to a depression, but which is well defined by a large rib on each side. The sinus is formed of five ribs, the central one being large, with a smaller one on each side, which last spring, a short distance below the beak, from the large ones, which limit the sinus. On either side of the sinus there are from sixteen to twenty-two simple ribs, marked by undulating lines of growth. On the ventral valve the varix is not raised, but is limited by two furrows, wider and deeper than any others on the valve, except the central one of the varix, which corresponds to the large rib in the centre of the sinus of the opposite valve. The varix is formed by two ribs, which originate at the beak and bifurcate after proceeding a short distance, so that it is made up of two pairs of ribs, divided by the large central furrow. The remainder of the ribs on this valve are like those on the opposite one. Cardinal area unknown. Dimensions.—Length, nine tenths of an inch; breadth, two inches. Comparisons and Dijerences.—This species differs from the S. attenuatus of Sowerby, which it most nearly resembles, in having fewer ribs on the sinus, and a much less number on the whole extent of the shell; and also in the ribs being simple, while in the attenuatus they are dichotomous. It cannot be confounded with any other species known to us. Geological Position and Locality.—It occurs in the middle of the Mountain Lime- stone series, at Burlington, Iowa. We have not been able, so far, to obtain specimens from any other locality, nor have we found the two valves united. It is rare. Explanation of the Figures.—P\. IX. fig. 3,a.

It is rather small, with the exception of the last whorl, the mouth part of which is enormously expanded, both in length and breadth. The shell is crossed from side to side by a series of large, wavy ridges, which are cut through in their centre by a deep longitudinal furrow. The ridges and furrow become obsolete on the expansion of the mouth. The entire surface is covered with fine longitudinal ribs, so numerous that it is almost impossible to number them. The mouth is, apparently, without a notch; exterior lip semicircular ; inner lip very much thickened, and, with the central parts, projects so far forwards as to form with the sides of the shell two semicircles. Geological Position and Localities—This is another most beautiful species belonging to the coal measures, and is found associated with the B. percarinatus and B.

GRAYVILLENSIS, nob.—PI. IX. fig. 7, a, b. Shell small, being about half an inch in breadth and the same in length. Whorls five, flattened above; the body whorl rounded ,below. Spiral angle 102°. Shell covered with longitudinal lines, crossed by lines of growth, giving it the appearance of being garnished with small tubercles. The upper line of tubercles on each whorl, near the suture, is much more prominent than the others, forming a raised ornamental band. The band of the sinus is large, and separated from the inferior part by a fur- row. Mouth sub-quadrangular; exterior lip sharp; columella lip thickened, the columella terminating below in a point. Geological Position and Localities.—This species occurs in the coal measures, and is quite common in the shales near the mouth of Rush creek, Posey county, Indiana, and Grayville, Illinois. It is also found near Shawneetown, and in the neighborhood of Galatia, Saline county, Illinois. Explanation of the Figures.—Pl. IX. fig. 7, a.

Fusus(?) inHaBitis, Morton.“ American Journal of Science and Art,” Ist Series, Vol. xxix., p. 150, fig. 14, plate 3. This species, which was found in 1834, by Dr. S. P. Hitpreru, of Marietta, Ohio, occupying the same position it does further west, was referred by Dr. 8S. G. Morton to the genus “ Fusus?” and published without any adequate description. Its occurrence in the same geological horizon over so large a district of country, gives it an impor- tance which renders it desirable to supply the deficiency. Shell nearly globular; spire short, forming an angle of 105°. Whorls five; the body whorl very large and inflated, while the remainder are comparatively small, and occupy only one seventh of the total length of the shell. Aperture semi-elliptical ; much longer than wide. Columella rather long, and furnished with a distinct fold. The length of a large specimen is 1 8-10th inches. This species resembles somewhat the M. Michotianus of De Koninck, but differs from it in its greater size, and in having but five whorls; that species having six. Geological Position and Locality.—This species is found in the middle of the coal measures at Grayville and Galatia, Illinois, and rather more abundantly, but of smaller size, in the shales of the same formation in Posey county, Indiana. It also occurs, according to Dr. Hitpret# in the same part of the coal series of Ohio. Illinois State Collection. Explanation of the Figures.—P\. TX. fig. 9, a. Front view of a large individual.

By Exias Duranp. This collection, which was placed in my hands by the Philadelphia Academy of Natural Sciences in the latter part of last year, is composed of about two hundred specimens, many of which, unfortunately, are in a very incomplete state. It was made during the spring and summer of 1851, in the vicinity of Nevada, a place situated on Deer Creek, one of the affluents of the Sacramento river, and occupying an intermediate position between the mountains of the Sacramento and those of Calaveras county. Nevada stands at an elevation of about three thousand feet above the level of the Pacific Ocean, near the junction of the granitic and schistose rocks. To the soil of the former, as well as to that of the porphyritic lavas, are confined the large pines, firs and arbor-vitee, while the nut pines and acacias thrive only on the schistose rocks. I am informed by Mr. Pratten that many of his plants belong, ex- clusively, either to the granitic or to the schistose formations, whilst others grow indif- ferently on both. Before entering upon a serious investigation of these specimens, I put aside all those that were new to me, with the view of submitting them to my friends, Profs. Torrey and Gray, who have had under examination several large collections of Cali- fornia plants. To the great experience and friendly assistance of these léarned botanists Iam highly indebted. They have been good enough to point out the species which they had already described in manuscript, and to procure for me Bentham’s Plante Hartwegiane, or descriptions of new plants collected by Hartweg in the moun- tains of the Sacramento river—a publication extremely rare in this country, and in which I found descriptions of many of the plants I had before me. All the new species of Mr. Pratten’s collection, described either by Profs. Torrey, Gray, Mr. Bentham, or by myself, amounting together to about forty, have been united in this essay, and may be considered as new matter, not having been published as yet in any American work. Whenever I have failed to obtain Professors Torrey and Gray’s notes, (their manuscript being in the hands of the printer,) I have endeavored to supply this want by giving my own diagnosis. 21 80 PLANTA PRATTENIANA CALIFORNIC.

Smaller than C. pratensis, but same habit and inflorescence. Radical leaves long- petiolate, sometimes entire, limb 12.15” broad, truncate at base, margin obscurely sinuate ; but oftener, above the middle of the petiole, with 2, or more seldom, 3—4 lateral segments, similar to the terminal one, only smaller and long petiolulate. Cauline leaves few and small, generally 3-partite, with narrow segments much smaller than the terminal one.”* * T have specimens of a cardamine, collected by Dr. Heermann on the bars of the river Calaveras, which I con- sider as a form of C. paucisecta, although somewhat differing from Hartweg and Pratten’s plant. ‘ As is frequently the case with California specimens, the radical leaves are wanting ; but towards the middle of the stem the first cauline leaves begin to appear. These are 5=-7 pinnately divided, and answering pretty well to PLANTA PRATTENIANA CALIFORNICA. §1 ERYSIMUM Arxansanvm, Nutt. in Torr. and Gr. Fl. Am. vol.i. p. 95. With orange colored flowers. In my opinion Z. asperum, D.C., Arkansanwm and elatum, Nutt., might be considered as different forms of one species. £. asperum is somewhat canescent, but they are all more or less scabrous, with appressed medio-fixed hairs; the lower leaves are runcinate-dentate, those of the stem dentate or entire; the flowers are large, varying from light yellow to orange, the petals have very long claws and obovate limbs ; style short and thick, with a bilobed stigma. . elatwm (Nuttall’s specimen) is a lank and elongated form about 3 feet high. Hilly sides of Deer Creek. August. POLYGALACE A. POLYGALA cucutiatra, Benth., Pl. Hartw. p. 299. “ Diffusa, puberula, foliis ovalibus vel oblongo-ellipticis, obtusis retusisve ; racemis brevibus plurifloris, sepalo infimo basi gibbo, alis oblongis, carina imberbi apice in cucullum oblongum producta. Stems branching, prostrate, the lowest part perennial and almost woody ; branches herbaceous, slender, 4—6” high, pubescent; leaves with very short petioles, the lowest small ovate, the upper 6—8” long, rounded at tip or often emarginate, cuneate at base, with margins slightly recurved, green on both sides and not punctate, pube- rulent above, almost glabrous underneath. Flower (rose colored?) 4” long. The exterior sepal concave at base, saccate, oblong ; the two superior a little smaller and one-half narrower. They are all membranaceous and colored, the two lateral (wings) twice longer and more slender, obliquely subovate-oblong, equalling the wings of the corolla, and a little shorter than the keel. Lateral petals, or wings, lanceolate and slightly adhering to the base of the keel. Keel split in front, dilated above the base and contracted towards the middle, then abruptly dilated, subrhom- boid and terminating in an erect obovate-oblong and obtuse hood. The stamens do not reach the base of the hood ; the filaments are fixed to the keel as far as the rent, where they become free. The style is flexuose, tubular, dilated at top and truncate, the stigma resting on the margin. Ovary stipitate, capsule subsessile, orbicular, emarginate. There are also, at the base of the leafy branches, short fructiferous branchlets, bearing capsules rather smaller than those of the upper branches, and perhaps produced by apetalous flowers.” The few small specimens I find in Mr. Pratten’s collection differ only from the above description in having the hood conspicuously mucronate; but Dr. Torrey informs me that, in the specimens of Col. Fremont, some have the mucro, whilst others have it not. Bentham’s description of the radical leaves of C. yaucisecta, The upper leaves are ternate, and the leaflets of all the leaves are rhombic-ovate, petiolulate and repand-dentate; each axil is furnished with a few-flowered stipitate raceme, provided with a leaf-like 3-parted or dentate bract. The terminal raceme is 12—15 flowered; the sepals are ovate, with a whitish margin, 4 the length of the petals, which are white slightly tinged with pink. The root appears to be tuberous, and the stem and petioles are succulent. 82 PLANTA PRATTENIANA CALIFORNICA. VIOLACE A. VIOLA Becxwiruu, Torr.’s MSS. for Beckwith’s report, “subcaulescens, ad- scendens, caule abbreviato; foliis caulinaribus biternatis vel palmati-sectis, decur- rentibus, lobis vel segmentis oblonge-linearibus, hirsutis, pubescentibus; stipulis minutis, scariosis, integris; sepalis linearibus obtusis, ciliolatis, petalo infimo ad basim remisse saccato, purpureo, ad unguiculum luteo, 2 superioribus brevioribus dense violaceis.” Pratten’s plant, although evidently the same as V. Beckwithii, differs slightly from the above description. It has but a few pentagonal reniform leaves on long margined petioles; these leaves are 3-divided, or pedately parted with cuneiform 2—3 cleft elliptico-linear segments ; stipules small, membranaceous, fimbriate ; two very minute bracts about the middle of the peduncle; flowers rather small, on peduncles shorter than the petioles; sepals linear-lanceolate, spur scarcely any ; stigma orbicular oblique, fringed with short hairs.

Sepalis lanceolatis acutis, corollee calcare brevi sacciforme.” “Rhizoma short, ascending. Stems half a foot high. Inferior stipules two lines wide and auriculate at the base, the superior ones narrower acute. The lower leaves are more wide than long, on long petioles, with lobes ovate or oblong, obtuse or acute, and mostly divided above the middle of the lamina; the upper leaves are generally trifid, with the middle lobe larger than the others, on peduncles about two inches long, pro- vided, above the middle, with two small approximate or distant bracteoles. Flowers yellow? petals beardless. The appendices of the anthers very unequal; the superior a little shorter than the anther itself, the inferior very short. Style clavate, incurved, with an oblique stigma, and ciliate with retrorse hairs under the stigmatose part.” In my specimens the stems are striate, branching, eight inches long. The leaves are strongly veined, the inferior glabrous, cordate, palmately divided from about the middle, with lanceolate lobes; the upper are pubescent-scabrous, ovate-rhomboid, with lateral dentiform lobes. The stipules are foliaceous, broadly-oblong, mucronate- dentate, or entire and lobed, attaining towards the middle of the stem twice the length of the petioles. The flowers are numerous, on rather short peduncles, each having two small bracts, distant or approximate, above the middle. Petals apparently bluish in-my specimens, obovate, twice the length of the sepals; lateral ones some- what bearded at the claw; spur wide and saccate; style incurved, ciliate with retrorse hairs under the oblique stigma.

Caulis subramosus, debilis, pubescens, foliis caulinaribus oblongo-lanceolatis, integris, ciliatis, fere semiamplexicaulibus ; cymis trifloris; calyce ample elliptice-cylindrico, obscure striato, pubescente, dentibus late ovatis, margine membranaceo ciliato ; petalis purpureis magnis quadrifidis, lobis mediis amplis, pro- funde partitis, obtusis, lateralibus minoribus acutis, unguiculis latis, ciliatis ; staminibus tubo exsertis. This plant, of which I have several other specimens collected at Calaveras by Dr. Heermann, may be the 8. Virginica of Benth. Pl. Hartw.; but its characters are so constant that I feel justified in separating it from that species, which it resembles at first sight. It is more pubescent, the stem and calyx less striate than in the latter, and I have not seen more than three flowers in each cyme, whilst S. Virginica has generally more, and SS. rotundifolia, with which it has likewise some affinity, has them solitary or in twos. Its habits are also very different from those of S. regia and S. Greggti, which are robust and erect plants, with thickish oval or obovate leaves. In S. regia the petals are entire, in 8. Greggit they are 4-fid with linear lobes, in 22 84 PLANTA PRATTENIANA CALIFORNICA. S. Californica the middle lobes are considerably larger than the lateral. Internodes 2—4 inches long. The calyx is not clavate, but uniformly expanded and perfectly . cylindrical, with delicate strize. The lamine of the petals are always four-lobed, two large obtuse lobes in the centre and two smaller and acute on the sides. Flowers deep scarlet. Hills of Deer Creek. May. S. CALIFORNICA, var. miniata, var. nov. Caulis erectus, simplex, 6—8 pollicaris, foliis ovato-lanceolatis acutis, basi attenuatis, sessilibus; internodiis 1—13 pollicaribus; cymis 3-floris; calyce omnino conformi S. Californice ; petalis miniatis, bilobatis cum dentibus lateralibus duobus. The most striking characters of 8. Californica are the tubular form of the calyx and the four-lobed petals; in the variety miniata the petals are not exactly four-lobed, the lateral teeth are too small to be accounted lobes, but the calyx and the claws of the petals are exactly the same. The latter might, however, prove to be a new species, if the minium color of its flowers is constant. Its leaves differ in being oval- lanceolate and more attenuate at base than S. Californica; it is also a smaller plant, with comparatively short internodes. Dr. Heermann brought it from Calaveras, mixed with specimens of S. Californica. S. MULTICAULE, Nutt. in Torr. and Gr. Fl.

Po eee , oe ae ATOMIC HEAT TO CRYSTALLINE FORM. 129 increased capacity for heat is about one-tenth, the increase in expasion amounts to one-hundredth. But we cannot conceive of this expansion taking place without the atoms being moved farther apart, thus increasing the volume. Coincidently with this change, and as a proof of its reality, we find the specific gravity of the metal diminish- ed. Hence it is, that the capacity for heat of any body increases with the temperature ; - for the arrangement of the atoms at greater distances from each other must necessarily afford more space for the accumulation of caloric around the particles. Thus the specific heat of copper is reduced, by violent hammering, from 0-095 to 0-935; but raised again by ignition, to 0.0949. Lead and tin, on the contrary, which do not in- crease in specific gravity under the die, likewise suffer no diminution of specific heat by pressure. The specific heat of soft bell-metal, (Cus) Sn) which has a density of 86843 is 0:0862, while the same metal hardened, in which state its density is 8:5797, has a specific heat of 00858. (Regnault.) The more dense a body is, the ereater is its specific gravity and the less its specific heat. A beautiful example is given by Regnault in the case of precipitated silver. The specific heat of this sub- stance varies with the degree of condensation, as shown by the following results de- termined by the method of cooling :— 20° to 15° 15° to 10° 10° to 5° Very little pressed, 5 : : 0:08535 0:08441 0-08519 More strongly ‘“ F : ; 0-05844 0-05772 - 0-05781 Still more t s : : 0:05749 0 05718 0-05749 Strongly hammered and rubbed, _.. 0-05634 0-05671 0-05654 More strongly <“ Mt : 0:05616 0-:05624 0:05650 Peroxide of iron and peroxide of nickel when strongly ignited, increase in density and diminish in specific heat. The varieties of carbon present the same result. The interesting experiments of Messrs. Hopkins, Fairbairn and Joule, upon the effects of extreme pressure, demonstrate that the temperature of fusion increases in proportion to the pressure to which the fused mass is subjected. In employing a pressure of about 13,000 lbs. to the square inch, on bleached wax, they found that increase in the temperature of fusion was not less than 30° F., about one-fifth of the whole temperature at which it melts, under the pressure of the atmosphere.* Such facts, I may say in passing, militate strongly against the generally received, though probably erroneous theory of the exalted calorific condition of the centre of our planet. But the active agency of caloric in affecting specific gravity, is seen by comparing compound bodies with the elements of which they are composed. Thus hydrogen and chlorine unite, without condensation, to form hydrochloric acid gas. The specific gravity of one volume of hydrogen is 69:26; of one volume of chlorine, 2421-6; and of one volume of hydrochloric acid gas, 1247-4 ; the mean of the two former numbers. The specific gravity of hydrogen is about 36 times less than that of chlorine; its * President Hopkins’ Address befure the 23d Annual meeting of the British Association. 130 M#IGS ON THE RELATION OF elastic force, on the contrary, is exceedingly great; while cold alone, or a pressure of but four atmospheres is sufficient to condense chlorine. The expansive power of hydrochloric acid gas, is equal to the pressure of 40 atmospheres, at the temperature of 50°. Now the atomic heat of H is 21:2064; of Cl, 14-4627; and of HCl, 28-9263. Four volumes of HCl must contain as many atoms as two volumes of H, or of Cl; or, two volumes of HCl contain as many atoms as one volume of H or Cl. But one volume of H contains half an atom, hence one volume of HCl must contain one-fourth of an atom, which must therefore be surrounded by twice as large a heat-sphere as the half-atom of H. Such facts authorize us to conclude, that chlorine in combining with hydrogen has its specific gravity reduced, in consequence of abstracting from the latter gas an additional quantity of caloric, by which its particles are separated further from each other and made to occupy a larger bulk. This supposition will also account for the change in elasticity. The union of iodine, bromine, cyanogen, &c., with hydro- gen is accompanied by a similar reduction in specific gravity, and alteration in physi- cal and chemical properties. When hydrogen unites with sulphur, phosphorus, and arsenic-vapors, and with carbon, in different proportions to form, respectively, sul- phuretted, phosphuretted, arseniuretted, and light and heavy carburetted hydrogen gases; with oxygen to form aqueous vapor, and with nitrogen to produce ammonia, the resulting specific gravities of these respective compounds is very much less than the sum of those of their constituent elements, The volume and elastic force of these gases are also altered in a remarkable manner. According to Graham, the more nearly bodies agree in composition, they are the more likely to act as solvents of each other, or to be miscible in the liquid form.* But we have seen that in both compound and elementary bodies of the same atomic con- stitution and of like chemical constitution, the specific heats are in the inverse pro- portion to the atomic weights. In this connection, I may refer to those numerous and interesting examples of change in the solubility of bodies after being heated, although their composition remains the same. Alumina, binoxide of tin, sesquloxide of chromium, and other metallic peroxides, and certain salts, such as silicates, tung- states, phosphates, antimoniates, &c., after exposure to a temperature just below red- ness, lose their solubility in acids. In its cubic form, the bisulphuret of iron resists the action of both air and water; but in its right rhombic form, when exposed to moist air, it absorbs oxygen with great avidity, and is converted into a crystalline mass of copperas.; Spontaneous ignition often accompanies those changes in solubility, and generally just as the body is passing from the soluble to the insoluble state. “Je crois méme que ce changement de chaleur spécifique correspondant 4 un changement d’ agrégation, donne l’explication d’une phénomeéne bien connu des chimistes et des physiciens, je veux parler de l'incandescence qui se manifeste subitement dans certains * Hlements, p. 142. + Kane.

Kn effet, la substance qui etait facilement soluble dans les acides, avant son incandescence, est devenue trés difficilement soluble, quelquefois méme insoluble aprés. L’incandescence s’explique facilement par une diminution subite dans la capacité calorifique du corps, qui dégage instantanément de la substance une quantite considérable de chaleur qui auparavant était latente; cette chaleur, au moment ou elle devient libre produit nécessairement une élévation thermométrique qui porte pendant quelques instants la substance 4 l’in- candescence, quand elle n’ était encore portée qu’ au rouge sombre par la chaleur ex- tenmeures, = In the Annales de Chimie et de Physique, (ler ser. t. 70, p. 407,) Gay-Lussac has published some observations upon certain bodies whose solubility he shows to be deter- mined by temperature alone. These observations lead, moreover, to the supposition that all spontaneous precipitations are due to differences in temperature. Many elementary bodies in uniting to form compounds, suffer a contraction in volume. Now, M. Filhol has shown, that in those compounds whose chemical properties are very analogous, the co-efficients of contraction are sensibly the same.+ Analogous properties seem to be associated with analogies in calorific condition. It would be superfluous to adduce other examples of the active character of caloric. From the laborious and carefully conducted experiments of many eminent physi- cists, we may infer that in the most, if not all bodies, the combined heat varies to a greater or less extent in different specimens. Examples of this we find in carbon, sulphur, &c. Accompanying this variation, and in all probability caused by it, we find a change in form, condition, physical and chemical properties and the like. Indeed it is difficult to conceive how any change, even the slightest, in the heat of a body, could be unaccompanied by some alteration in the ponderable matter. The extreme sensitiveness of heat or caloric is evinced in every chapter of its endless history. It is very rational to suppose, therefore, that the influence of caloric in moulding ponderable matter into definite forms, must in a certain measure vary with the degree of aggregation of the body, which state of aggregation is indeed in great measure contingent upon the amount of caloric itself. Increased aggregation is gene- rally an indication of diminished calorific capacity. In colcothar and the diamond we have beautiful examples of this fact. In condensing very strongly, a body often completely loses its most characteristic chemical properties. Heat acting upon two dissimilar pieces of metal soldered together, gives rise to electrical phenomena; acting upon water, produces motor effects. From such conspicuous examples we are forced * Regnault, Ann. de Chim. et de Phys. 3me Sér. i. 188--9. + Annales de Chim. et dle Phys., 3™° sér. t. xxi., p- 415. 34 132 MEIGS ON THE RELATION OF to conclude that any variation in the ponderable substratum or medium upon which a definite amount of caloric is made to act, or im the attending circumstances by which the body is surrounded, must necessarily produce a variation in calorific effects. Hence the want of absolute identity in the crystalline form of many bodies which are really isomorphous. Hence, too, the discrepancies occasionally met with between the atomic volume of a body and that of the other members of the group to which it belongs. For atomic volume is calculated from relative weight and specific gravity ; as the latter two vary, so must the former. Now the specific gravity of a body may vary according as it is adulterated or not with matters lighter or heavier than itself, and having naturally different quantities of heat; or the body itself may, in different states, possess different quantities of combined heat. This view will explain the fortuitous coincidences in form accompanying dissimilarity of properties and compo- sition; and, also, why certain elements manifest isomorphism in their analogous compounds, and yet cannot be shown to be isomorphous in their elementary state. For the mathematico-chemical investigations of Kopp lead us to suppose that the primitive atomic volume of an element suffers a considerable change in its different combinations,—the combining volume bearing in most instances a simple or multiple relation to the primitive. Hence a body may have two or more atomic volumes as well as crystalline forms, which, indeed, we should infer a priori. _ We know very well that a certain elevation of temperature may so affect the molecular structure of a body as to destroy its identity or individuality,—changing its form, color, properties, &. This molecular change is nearly always accompanied by a simple multiple change in the equivalent of a body, and of course in the atomic volume. It seems very probable, therefore, that the different forms which certain elementary bodies are known to assume, are intimately connected with diversity of equivalent volume. We may suppose that sulphur has a larger and more intricate volume when it takes the complex form of bisulphate of potassa, than in its ordinary simple form. So, likewise, we may suppose that when one equivalent of chlorine replaces one of cyanogen, or two of manganese in combination, it must have a varying volume, and consequently a varying form, in compound bodies. According to Graham, the tendency of discovery is to bring all the elements into one class, either as isomorphous, atom to atom, or with the relation to the others which sodium, chlorine and arsenic exhibit. In this connection, the sameness of atomic heat of the elements, the similarity of many of the atomic volumes, and the simple relationship of the others, as shown in the table, are significant facts. If we ignore the materiality of heat, and deny that it is as essential to the compo- sition of bodies as ponderable matter itself, the changes in form, properties, &., which these bodies undergo, are without explanation. If, on the contrary, we follow the evidence of our senses, and acknowledge the substantiality of caloric and the extent ATOMIC HEAT TO CRYSTALLINE FORM. 133 and dignity of its influence upon the self-inert bases with which it is combined, we open a channel for the hopeful investigation of cause and effect. Changes in the properties of things must be preceded by compositional and structural changes, either of their ponderable or imponderable element, or of both, just as in the animate world organic derangement is the invariable antecedent to functional disturbance. If caloric be merely a property or quality of matter, it cannot possess that self-active and causative power which a careful analysis of its history warrants us in assigning to it. If it be a substantive entity, we can readily understand the remarkable constancy and mathematical precision of its effects; and we can understand, furthermore, how its presence or absence in certain quantities can produce those structural or molecular alterations which manifest themselves externally in variations of form, specific gravity, color, solubility, &. The estimation of the absolute amount of heat combined with bodies in their different states of aggregation, is one of the most difficult problems in physical science ;—and one of the most important, since upon its solution depends the explanation of many unexplained and apparently inexplicable phenomena. However, if we bring together the few reliable observations that have been made in this channel, (especially those concerning the relation between the calorific condition and refractive power of substances,) and the numerous collateral facts which are scattered throughout the literature of physics, we will have material sufficient to begin already the work of cautious and satisfactory generalization. The following conclusions, as being more or less probable, seem to flow naturally from the foregoing facts and arguments :— 1. That no invariable connection exists between the form and ponderable atomic constitution of a body. 2. That form is immediately dependent upon peculiar axial proportions, which are themselves the results of a certain molecular arrangement. 3. That the arrangement and disarrangement of atoms implies a motor agent; while the definite and constant relation between changes in aggregation and variations in form, implies the materiality of this agent and its continued presence, whether in the same or varying quantities. 4, That this agent has periods of action and periods of rest. 5. That caloric is a positive material entity—an essential element in all bodies, always present in different proportions. 6. That caloric is selfrepellant and endowed with great physical power. 7. That crystalline form is the visible representative of atomic volume. 8. That isomorphous bodies have sensibly the same atomic heat and the same atomic volume. 9. That in elementary and compound isomorphous groups, the numbers indicating atomic heat and volume are simply related. 134 RELATION OF ATOMIC HEAT TO CRYSTALLINE FORM. 10. That two or more atoms of one element may replace one of another, and retain the same figure; and vice versa; hence, equal numbers of atoms are not essential to isomorphism. 11. That similarity of constitution is- generally, though not always, accompanied by sameness of combined heat. 12. That at certain temperatures, the elements may all be made to assume the same form. 13. That variation in the atomic heat of a body is accompanied by variation in its form. 14. That atomic heat is the cause of isomorphism and polymorphism,—consequently of crystalline form in general. Is caloric, through its affinity for, and active influence upon ponderable matter, the primary physical cause of all crystallization ? et = [135] ART.

Quite abundant at Point Judith, adhering to corallines, and other fuci, mytili, &c., below low tide, Gertner,* Van Beneden,t+ Hassal,{ and Johnston§ represent Coryne as haying the tentacule terminating in globular extremities and irregularly distributed, while Eudendrium is represented as possessing only a circle of filiform tentacule. Such being the case, the polype, above described, would characterise a genus intermediate to Coryne and Eudendrium. Gosse|| has, however, represented two polypes, which he calls Coryne cerberus and Coryne stauridiai, each having a circle of simply filiform tentacule, and a second of those with globular tips. As an examination of Hucoryne elegans shows the two kinds of tentaculz to have a different arrangement in structure, the two species just named either do not belong to the genus Coryne, or all the species of the latter possess filiform tentaculz, and others with globular tips, which I suspect actually to be the case, when the genus Hucoryne would cease to exist. Eucoryne elegans is an exceedingly beautiful object, on account of the profuseness of its developement, its graceful branching, and varied coloring. lI observed many bunches four inches in length, but the main branches do not measure more than three inches; the addition of length in the branches, being due to the successive origin of the latter from stems of corallines, or other elevated objects of attachment. The root of the polypidom is a coarse, tortuous, black fibre, reticulated upon the ob- ject of attachment. Sometimes an ascidia is imprisoned by the net-work, but more frequently it embraces the stems of corallines, or entangles masses of minute mytili. * Pallas, Spicilegia Zoologica. + Rech. sur l’embryol. des Tubulaires. { Ann. and Mag. of Nat.

The trunks are black, and are annulated at their commencement, for a short distance after giving off the branches, and at their termination. The branches have the same color and character of annulation as the parent trunks. The branchlets are ochre-yellow, and annulated at their commencement and termination, or occasionally throughout ; and frequently they give off secondary branchlets. The polypes have the familiar form of the nine-pin, and are translucent white, with two purplish red bands encircling the body at the base of the first two circles of tentacule. The stomach of the animal is pink, and is visible through the trans- lucent parietes of the body, between the red bands. ‘The head of the polypes is conical, but in the expansion of the mouth is frequently observed to assume a cup shape. At the base of the polypes there is situated a radiating circle of twelve narrow, cylindrical tentacule, about one line in length, and capable of retraction, inflection, or complete reflection. The neck of the polypes is surrounded by two circles, each of six, comparatively short, cylindrical tentacule, with large globular tips. The long tentaculee of Hucoryne elegans are composed of an axis of large, nucleated cells, surrounded with a delicate muscular sheath, and enveloped in a thin, ciliated epithelium. Beneath these tentacule, extending their entire length, and enveloping the tips, there is a stratum of nettling cells. The short tentacule have the same structure as the others, except that the nettling cells are accumulated entirely at their extremities, and thus give to these their characteristic globular form. The nettling cells of Hucoryne vary in size, and present the same structure as the principal ones of the fresh water Hydra. When the cells are entire they appear as oval capsules containing at their fundus a hemispherical. mass of matter, which in some instances has appeared to me to consist of a coiled thread, as represented in figure 6, plate X. Above this mass or coil is a narrow oval capsule, within which is a style, the point of which slightly projects from the summit of the nettling cell. When the latter has emitted its thread, it appears partially collapsed, and from its summit projects an irregular cone with four barb-like processes at the sides, and the thread protruded from the apex, as represented in figures 5, 7. As in other compound polypes the soft structure of the animals is continued as an axis throughout the polypidom. This axis contains numerous nettling cells, as large and as well developed as those of the tentacule. What can be their office in this position ? Hucoryne elegans produces medusa-like buds, in numbers of one to four, situated just above the position of the first circle of tentacule. Very frequently a pair of these buds become fully developed at the same time, and then appear larger than the parent. 138 LEIDY ON THE MARINE INVERTEBRATE FAUNA OF They are attached by a narrow pedicle, are oval in form, and white in color, with four longitudinal bands of purplish red. They have four short, conical tentaculz and measure about half a line in length by one-third of a line in breadth. In one instance, I found a small bunch of Hucoryne elegans, in which the polypes had only two circles of tentaculz: the long cylindrical ones and a circle of the short ones. Since writing the foregoing, Mr. Ashmead has given to me several dried specimens of Eucoryne elegans, from Great Egg Harbor. The bunches are not so profuse as those of Point Judith, but one of them has a branch six inches in length. 6. LAOMEDEA GELATINOSA, Lamouroux.

Polypidom very much branched; branches alternate, annulated at their commencement, the larger ones brown, the smaller ones light-yellow; branchlets annulated throughout, or at their commencement and termination, from one to three times the length of the polype cells ; the latter campanulate, with an even margin. Ovarian cells axillary, pedicled, two or three times the length of the polype cells, urn-shaped, with the pedicles an- nulated. Found abundantly, growing in profuse bunches, three inches in length, attached to a submerged wreck on Absecom Beach. Specimens obtained by Mr. Ashmead. The nettling cells of the tentacule of Laomedea are numerous, and are arranged in circles. They are elliptical in form, often curved, and minute; measuring from -0067 mm. to ‘0089 mm. long by :0022 mm. broad; and they contain a central style ex- tending from one pole of the cell half through its length. These cells, of which two are represented in figure 8, plate X, I saw at no time emitting threads. 8. CAMPANULARIA VOLUBILIS, Lamarck. Point Judith. 9. CAMPANULARIA DUMOSA, Flemming. Point Judith.

Coral masses up to two inches in diameter. Point Judith. Found attached to rocks just below low tide. / The polypidom of Astrangia ustreformis was first described by Milne Edwards and Haime, in the Annales des Sciences Naturelles for 1849. The living coral was first discovered by Agassiz who dredged it from a depth of nine fathoms off Gay Head in Martha’s Vineyard Sound.* At Point Judith I observed it in position attached to the rocks a little distance below the lowest tide mark. It is especially interesting from the fact that it is the only coral which has been discovered on the eastern shore of the United States. Dead specimens have long been known, and the cabinet of our Academy contains a number of them, among which is one attached to a fragment of a Fulgur, from ihe coast of South Carolina. Finding the living A. astreeformis afforded me an opportunity of examining its fili- ferous capsules. These are especially abundant in the tentacule, and in certain white cords of the interior of the body. The function of the cords just mentioned is yet unknown. I frequently observed them extruded from wounds of the body of A. astreformis. Wien detached they will spontaneously roll into a close coil; and are composed of filiferous capsules arranged in a radiant manner around a central cellular axis, enveloped in a delicate, actively vibrating ciliated epithelium. The filiferous capsules of A. astreformis are of two principal varieties. The first variety consists of oval, or ovoidal cells, about .05 mm. long by .0155 mm. broad, containing a spirally wound thread, as represented in figures 11, 12, plate X. The second variety consists of smaller cells; those of the tentacule measuring about .045 min. by .0067 mm., and those of the white cords .03 mm. by ‘0112 mm.; and they contain besides a spirally wound thread, a style extending from one pole to about the centre of the cells, as represented in figures 9, 10. Both kinds of filiferous capsules, under certain circumstances not readily explained, eject their contained threads with an astonishing degree of rapidity, and in so doing the threads are absolutely turned inside out, as was first noticed by Agassiz,; and sub- * Proc.

Assoc. 1850. 36 140 LEIDY ON THE MARINE INVERTEBRATE FAUNA OF sequently by Gosse,* and remain attached to the emptied cells as long extended tubes, From the smaller cells the style is also extruded, and then appears as a more expanded portion of the thread, with which it is continuous at one end and with the capsule at the other, as seen in figures 15, 16. An attentive examination of the extruded thread exhibits a more complicated structure than would have been suspected, and as remarked by Agassiz, who first detected the peculiar arrangement, its exact character is exceed- ingly difficult to ascertain and requires the utmost power of the microscope to analyze. In the case of the larger capsules a spiral arrangement is readily distinguishable, ex- tending the entire length of the extruded thread. This arrangement in some instances appeared to me to depend upon minute cilise, which project at right angles from the thread, and apparently pursue a spiral course, as described by Agassiz, and as repre- sented in figure 15; but in other instances, it appeared to me as if the thread during its eversion from the capsule, assumed a spiral course within the portion preceding it, and that the thread externally was encircled at regular intervals with non-vibrating cilia, as represented in figure 14. In the ease of the smaller capsules the extruded style appears as a tube much dilated beyond its original calibre, narrowed at the extremities, and longer than the cell which contained it, so that it appears to have been folded within itself. From the distal extremity of the stylous tube projects the everted thread, which at times appeared simple, but at other times appeared to possess a spiral arrangement, like the coarser thread of the larger capsules. The tube derived from the style also presents a spiral arrangement, apparently dependent upon long cilize pursuing a spiral course as repre- sented in figure 16, or upon a twisting in the tube as represented in figure 15. 13. AcrrniA MARGINATA, Lesueur. Body when contracted, in the form of the segment of a large sphere; when expanded, cylindrical; brown in color with longitudinal bands of brighter brown. Tentacular disk deeply folded, translucent brown.

Mouth nearly circular, surrounded with an irregularly lobate, bright orange or reddish brown lip. This species is abundant at Point Judith. In one position, beneath an overhanging rock, a short distance from Mr. Hazard’s residence, I observed a group in the highest state of development. Some of the individuals measured four inches across the ten- tacular disk. Var. ambrea. Attached to fuci I frequently observed small specimens of an Actinia, two or three lines in diameter, and of a translucent ambreous appearance, which I suspected to be the young of A. marginata. * The Devonshire Coast. ¢ THE COASTS OF RHODE ISLAND AND NEW JERSEY. 141 Var. salmonea. I found two specimens of an anemone of the same form as that of Actinia marginata, about an inch in diameter, and of a bright salmon color, which I suppose to be only a variety of the latter species. It was attached to large mytili, appeared to be more active than the undoubted A. marginata, and when irritated ejected jets of water from large pores of the body, a phenomenon I did not observe in the more ordinary variety. . The filiferous capsules of Actinia marginata are numerous in the tentacule, but especially so in the white cords of the interior of the body. (PI. X, figs. 17, 18). They are elliptical in form, and measure about the .06 mm. in length by the .004 mm. in breadth; and they contain a spirally coiled thread and a style extending from one pole about two-thirds through the centre. The ejected contents of the capsules present two different forms. In the one case the style assumes the appearance of a spindle-shaped tube, several times its original length, apparently having the extrud- ed thread of the capsule coiled within it and having on its exterior long ciliary ap- pendages, as represented in figure 21. In the other case the extruded style assumes the appearance of a long narrow tube, apparently with the projected thread partly coiled within it and partly everted from its distal extremity as represented in figures 19, 20. 14.

The stellate variety is very abundant at Point Judith, encrusting the ruffled borders of Laminaria saccharina. It is also found encrusting Chondrus crispus, the shells of Mytilus edulis, etc. Tn all the specimens I observed, the cells possessed four lateral spines and a posterior spine, and this in no case was developed to the dimensions which would give it the name of a bristle. 16.

This species of Escharina may have been already described under half a dozen names, but I found it no easy task to determine which they are. The Célleporide are subject to great variety of form, and require much study before the true species can be ascertained. 19. CrLnuLaria FASTIGIATA, Blumenb. Polypidom branching dichotomously.

Point Judith. This curious worm lives in tubes within the dead portions of Astrangea astreformis. It protrudes the anterior portion of its body with the orange colored antennz. The latter are contractile, from one to four lines long, and with the exception of the third or most robust one on each side, are tipped with black, as if to be subservient to the impressions of light. Its setee are quite simple, as represented in figure 47, and are about the fifth of a line in length. The podal spines consist of a long style ending in a bowl, like that of a spoon, as represented in figure 48. For the new genus, of which the worm just described is the type, I have adopted the Indian name Narragansett, being that of the bay, on the shores of which the animal was first discovered. 34.

Head prominent, provided with a pair of large oval disks situated posteriorly. Mouth minute, at the summit of a trilobate papilla. Antenne very small and indis- tinct. Divisions of the thorax posteriorly strongly costate. Feet in seven pairs, curved forward and downward, ending in a short recurved, abortive hooklet. Abdo- men deeply segmented.

External antenne long, seven jointed ; the first two joints spinous, the others bristled. First joint of the thorax transversely oblong, the remainder depressed, pyriform in outline. Feet in seven pairs, the ante- penultimate joint spinous, the penultimate joint broad and with the claw recurved. Abdominal segments depressed, pyriform in outline, each provided with a pair of pe- culiar ventral appendages, and, except the fifth one, with a lateral irregular pigment cell. Caudal segment round, with a pair of divergent appendages. Length of female four lines, breadth three lines; length of male one and a quarter lines. Found in the branchial cavity of Gelassimus pugilator, at Atlantic City. THE COASTS OF RHODE ISLAND AND NEW JERSEY. Toi The genus Cepon was first described by Duvernoy, in the fifteenth volume of the An. des Sciences Naturelles, but the individual he indicates as being the male of Cepon typus is evidently the female of another species. Cepon distortus is not a very abundant parasite, for after having accidentally found a specimen, in searching for others, I destroyed fifty fidler crabs without obtaining a second. The parasite produces no deformity, visible externally, of the animal it infests. The male was found in the embrace of the female, as commonly observed in the isopodous crustacea. In making out the foregoing list of crustacea, I have availed myself of the aid of Dr. Bridges’ knowledge of this class of animals. CIRRIPEDIA. 83. ANATIFA STRIATA, Brug. 84.

This species considerably resembles C. awtwmnalis, (Linn.) but is invariably smaller and has no yellow markings on the face. The bill is clear yellowish white, with no tinge of brown or horn color, as in that species. The extent of the space on the head occupied by both the crimson and bluish ash colors, varies much in different specimens, and in one the latter color is nearly invisible. 3.

XIII.—Descriptions of some remains of fishes from the Carboniferous and Devonian Formations of the United States. By Josern Lerpy, M. D. EDESTUS, Leidy. Generic Characters.—Maxillary bones segmented ; segments beveled anteriorly and excavated posteriorly for coadaption. Teeth in general form resembling those of Charchavodon ; one coossified with each maxillary segment. ‘Epestus vorax, Leidy. Proc. Acad. Nat. Sci., vii, 414. The subject of the present description is a fossil fragment of the jaw of a remarkable and gigantic fish, which was presented to the Academy by William S. Vaux, Esq., who obtained it from an itinerant showman. The latter informed Mr. Vaux, that the specimen was discovered at Frozen Rock, Arkansas river, twenty miles below Fort Gibson, in the Indian Territory. The specimen is dense, heavy, and jet-black ; and when it was first received the crevices about its surfaces were filled with carbonaceous matter. It was probably derived from a coal bed; but the geological features of the locality from which it was obtained I have been unable to learn. The fragment of jaw is six inches in length ; and it measures three inches in depth from the dental border. ‘The sides are symmetrical, and slope divergently from the latter position towards the base, which is convex and moderately keeled in the median line. At the dental border the jaw is about seven eighths of an inch in thickness, and and at the thickest part cf its base measures one inch and four-fifths. Longitudinally the base of the jaw is slightly concave and furrowed. The surface of the bone is covered with fine vermicular, reticulating, broken ridges, assuming a striking resem- blance to arabic writing. The most remarkable peculiarity of the jaw is its segmented character; and of the segments the fossil retains two very nearly perfect ones with portions of two others. Each segment in outline forms an irregular pentahedron ; and each: possesses a single coossified tooth, whose broad surfaces abruptly increase the acclivity of the sides of the jaw. From its general form the fossil might readily be taken for a portion of the lower jaw, but from the fact that no vertebrated animal, neither living nor extinct, has jet been discovered in which the dental branches of the inferior maxilla are segmented, while several genera are known, as he Peele among living fishes, and the 160 LEIDY’S DESCRIPTIONS OF REMAINS OF FISHES FROM Dendrodus of the Old Red Sandstone,* in which the superior maxille@ are segmented, therefore it is a fair inference that the fossil in question is a portion of an upper jaw. The maxillary segments of the fossil are beveled off on each side anteriorly to a nearly acute edge, and are excavated posteriorly, so that the succeeding segments shall fit into those in advance. Lach segment contributes to the sides of the jaw a band- like surface curving from the dental border as far back as the position of the second succeeding tooth, and then turning forward at a nearly right angle to the base of the jaw, so that when the segments are conjoined they appear separated on each side by > like grooves. Near the middle of the anterior margin of the beveled portion of the segments, on both sides there exists an oval foramen, the apparent continuation of a dental canal. The teeth of the fossil are so closely set upon the jaw that the anterior basal angle of those behind passes the contiguous angle of those in advance. Of the portions of four teeth retained in the fossil, two are sufficiently well preserved to obtain some idea of their form when perfect, as represented in the outlines of figure 1, plate 15. In general form they appear to be like those of Charcharodon, but differ in a number of impor- tant characters. They are compressed, conical, with coarsely dentated, trenchant edges. Their two broad sides are symmetrical ; and they curve forward, so that in the restored condition their anterior margin appears to be convex and the posterior margin concave. Their base presents on each side a lobe-like expansion which ex- tends upon the sides of the jaw, so that they look asif they were excavated and fitted upon the dental border of the maxillary segments. The width of the teeth at base is one inch and nine tenths, the thickness in the same position four fifths of an inch, and the probable length is about two inches. The denticles are slightly compressed conical, with trenchant edges, and are nearly two lines long and over one line broad. In structure the teeth are solid and consist of hard dentine. which is however of looser texture toward the centre; and they are invested with smooth, shining enamel, about the one sixth of a line in thickness. The teeth are firmly coossified with the maxillary segments, and indeed their dentinal structure is absolutely continuous with, and undistinguishable by the naked eye from the nearly equally dense ossific structure of the jaw. A careless inspection of the fossil, at its posterior broken border would mislead one to suppose the teeth were inserted by long fangs into the jaw, an appearance which arises from the narrow portion of one fragment, continuous with its tooth, being received into the excavation of the segment in advance.

Dorsal rays very large, compressed conical, with a large interior cavity ; the external surface furnished with oblique and longitudinal rows of tubercles or tuberculated ridges; without posterior rows of denticles. ORACANTHUS veTUSTUS, Leidy. Proc. Acad. Nat. Sci., vii. 414. This species is proposed upon an ichthyodorulite or dorsal ray, from the collection of Mr. Timothy Conrad, now forming part of the cabinet of the Academy. The specimen is from Missouri Territory, but the exact locality from which it was obtained is unknown. It is dense, jet black, and heavy; and it has its apex and base broken away. On one side towards the base it is crushed inwardly, and in this position there is a portion of adherent iron gray limestone, with a partially imbedded segment of a crinoidal stem, which Mr. Conrad views as an evi- dence that the dorsal ray was derived from the carboniferous limestone. In several places the ray is fissured ; but the parts appear to have retained their original relation- ship, and the form of the ray is nearly perfect. In its present condition the specimen is five inches long and two and two-thirds of an inch wide at the base ; and its thickest portion is about eight lines. Its form is flattened pyramidal and is curved a little backward and slightly also to one side. The broad sides and posterior margin are thickly covered with mammillary tubercles but the anterior margin is smooth. Between the tubercles the surface is slightly striated. On the right side the tubercles are arranged in rows, irregularly longitudinal, and irregularly oblique in the transverse direction. On the left side they are arranged more regularly in longitudinal rows, and they evince a tendency to become confluent in short transverse rows, which pursue an irregular waving course across the ray. On the posterior margin, which is obtuse, there are several longitudinal rows. The anterior margin of the ray is more obtuse than the posterior; and it narrows towards the base. The thickness of the walls of this ichthyodorulite is not easy to ascertain. The apex of the specimen exhibits a solid bony structure, but the base appears to present thin lateral walls and a thick wall to the anterior border.

It was presented to the latter gentleman by Townsend Ward, Esq., who, in a note, observes, it was given to him “ by the engineer of the stationary engine at the head of inclined plane number 3 of the old portage railroad,’ which crossed the Alleghany Mountains from Hollidaysburg, in Blair County, Pennsylvania. Mr. Ward further states, “it was obtained from a stratum about one foot thick, black, carboni- ferous, and calcareous, which was exposed by the excavation for the buildings to accommodate the stationary engine.” He then adds, “I obtained quite a number of other fossils there, and from the same stratum near Freeport, above Pittsburg, and I think on the Conemaugh, seventeen miles west of Johnston. I found the stratum distinctly marked at these different localities, and have understood it is alsoto be seen in Ohio, where it is as distinctly marked by its appearance and fossils. It is in the bituminous coal series, and has a coal seam beneath it.” The tooth is of an iron gray color, hard, well preserved, and perfect, except that the basal angles of the crown and the end of the fang are broken away. The crown has the form of one half of a broad, compressed cone. Its outer side is smooth, and transversely convex, but slopes in a nearly even plane from the tren- chant margins. The inner side is also smooth, and forms a vertical plane from the latter position, and is transversely concave. The trenchant edges, except at the basal angles, are nearly straight, and are minutely serrulated, or rather simply striated. The basal cingulum surrounding the crown is bow-shaped on each of the broad sides; and it is composed of about nine imbricating, parallel folds. Externally it slopes inwardly beneath the crown; and internally it forms a thick convex ridge de- scending much below its position externally. The fang is an osseous plate, thick at the middle and towards the broken end, but thinning towards the lateral borders, which are slightly bent, scroll-like, from within outwardly. The inner surface is transversely concave ; thé outer one is convex, and presents a wide groove following the course of the basal cingulum. The mvasurements of the specimen are as follows: Breadth of the crown (not en- tire) 14 lines; height, including the basal cingulum, internally 112 lines, externally 9 lines. Breadth of the fang 10% lines; length (not entire) internally 42 lines, ex- ternally 7 lines. Plate i6, figs. 4, 5, 6.—Outer, inner, and lateral views of a tooth of Petalodus alleghaniensis.

Holoptychius nobilissimus, Ag., Hall, Geol. of New York, pt. IV, 281, fig. 130. By this name I propose to distinguish the remains of the genus which have been discovered to the present time in Pennsylvania, although it may possibly include two species. Remains of Holoptychius are stated to be quite abundant in certain localities of the Old Red Sandstone Formation of Tioga county; but such as they are, consist- ing of isolated scales, cranial bones, and teeth, they are so exceedingly friable and the matrix so hard, or so soft and brittle that it is difficult to obtain specimens suf- ficiently perfect to be characterized. Among numerous specimens, for the most part consisting only of impressions left by the disintegration of the remains, presented to the Academy, by Timothy Conrad, Hsq. and Charles E. Smith, Esq., there are a few which I have ventured to describe, and which are represented in figures 9, 10 of plate 16, and figures 1-4 of plate 17.: One of the specimens, represented in figure 9, plate 16, is a portion of a large scale, with an impression of a portion of the remainder. It measures nearly 23 inches in length, and apparently has been ovally rhomboidal in its perfect condition. The covered portion of the scale constitutes nearly one half, and is smooth. The exposed surface of the scales, as indicated by the impress of the matrix, was furnished with coarse, longitudinal, flexuose, and somewhat ramifying ridges. A smaller scale, represented in figure 10, plate 16, of which specimens are more frequent than of the preceding, is 14 lines long and 12 lines broad, and is a rounded square. A little more than half its surface has been covered by the scale in advance ; ‘and the exposed portion of the surface is covered with coarse longitudinal ridges. This scale resembles an isolated specimen of one from Holoptychius nobilissimus, repre- sented in figure 26, plate 31 a, of Agassiz’ Poissons Fossiles, but is not at all like those represented in plate 23 of the same work. The impression of a tooth, left in a portion of matrix by the destruction of the original, from which a clay cast was taken, gives the form characteristic of the large teeth of Holoptychius, as represented in figure 1, plate 17. The tooth has been ten lines long and four lines in diameter at the base. It is conical, circular in transverse section, as represented in figure 2, plate 17, and is folded two thirds of its length from the base. A very imperfect fragment of a maxillary bone, consisting indeed of little more than the thin internal surface adhering to a portion of matrix, represented in figure 3, plate. 17, exhibits at the anterior extremity the remains of a large tooth, partially consisting only of its impression ; and further back at the margin of the bone it presents two conical denticles about one line long. 42 164 LEIDY’S DESCRIPTIONS OF REMAINS OF FISHES FROM A bone, the most perfect specimen preserved of the remains of Holoptychius amert- canus, represented in figure 4, plate 17, appears to be one of the branchiostegal plates. Itis trilateral, is sixteen lines wide, and appears to have been about twenty-two lines long. Its surface exhibits numerous short flexuose ridges, and tubercles, characteristic of the cranial bones of the genus. Plate 16, figs. 9, 10.—Scales of Holoptychius americanus.

Dorsal spine long, narrow, straight, compressed conical, hollow, longitudinally striated, furnished posteriorly with marginal rows of oblique denticles. STENACANTHUS NiTIDUS, Leidy. Proc. Acad. Nat. Sci., viii, 11. This genus and species are indicated by the specimen of an ichthyodorulite, imbedded in a fragment of rock of the Old Red Sandstone For- mation of Tioga County, Pennsylvania, and discovered by Charles E. Smith, Esq., who presented it to the Academy of Natural Sciences. In the same fragment of rock with the spine, there are also small portions of bones, and the impression of a tooth, apparently of Holoptychius. The specimen has its apex broken off, and also a portion of its left wall, exposing a large interior cavity, filled with the sandstone matrix. _ It appears to have been per- fectly straight in its length, and is long, narrow, compressed conical. The anterior border is convex ; the sides are longitudinally striated or grooved; and the posterior border is denticulated. There appears to be a pair of close rows of denticles, though the specimen only exhibits one. The denticles are triangular, directed obliquely down- ward and backward, and seven of them are equal to the space of half an inch. About half an inch below the broken summit of the specimen, a zigzag fissure or perhaps a suture crosses the spine, as represented in figure 7 of plate 16. From the two lower angles of the fissure, two others proceed longitudinally downward to the broken margin of the specimen. ‘These appear like real sutures, though they are most probably mere cracks, the result of fracture. The length of the ichthyodorulite in its present condition is two inches and two thirds, and its width at base about half an inch.

Opercular bones, thick, covered with hard and finely granulated enamel. Teeth large, compressed conical, with trenchant margins and a grooved base. THE CARBONIFEROUS AND DEVONIAN FORMATIONS. 165 APEDODUS pPRISCUS, Leidy. This species is founded upon specimens of a tooth and a fragment of bone, from the Old Red Sandstone Formation of Columbia County, Pennsylvania, which were sent for my inspection by Prof. Baird, from the cabinet of the Smithsonian Institution. The tooth is seven lines in length, compressed conical, with trenchant edges, and is slightly curved. The two broad sides are very nearly symmetrical; the transverse section being elliptical and rather abruptly narrowed towards the acute poles. The trenchant margins are entire, and the surfaces are smooth, except at their lower half, where the tooth is grooved as in Lepidosteus and Holoptychius. 'The base of the tooth is four lines and a quarter in breadth, and two lines and a half in thickness. The tooth appears to be solid, and is invested with thin enamel. The fragment of bone mentioned, which I have considered as having belonged to the same fish as the tooth, for no other reason than that they were found in association, appears to be a portion of an opercular, or perhaps a sub-opercular bone. It is thick and dense, and on the exposed surface is invested with thin, shining, and minutely eranulated enamel. Viewing the specimen as an opercular bone, it has been over two inches in length, and about an inch anda half at its widest part. Its anterior margin is thin, and beveled off for the fourth of an inch for adaptation to the preopercular bone. ‘The posterior margin is convex; the lower extremity is a little prolonged ; and the upper broken margin of the specimen reaches one line in thickness.

By Josepu Leipy, M. D. CamELops Kansanus, Leidy. Proc. Acad. Nat. Sci., vii, 172. This genus and species are established upon a fragment of the anterior extremity of an upper jaw of an animal of the camel family, discovered by Mr. Henry Pratten, of New Harmony, Indiana, in the gravel drift of Kansas Territory. : The specimen consists of portions of the left maxillary and intermaxillary bones, — the latter of which contains the fang of a transformed incisor or functional canine. tooth, as in the lama. The intermaxillary bone is of very much more robust proportions than in the lama or camel. Its upper part and outer surface form the segment of a slightly flattened. cylinder, and from the nasal side to the outer side of the aperture of its alveolus it is an inch in breadth, while in the lama in the same position it measures only the third of an inch, and in the camel about half an inch. The inclination of its nasal border approaches more the horizon than in the lama or camel, apparently indicating the animal to have possessed a lower and perhaps a longer face than in either of the latter genera. The gingeval border is rugged as in its congeners, and it presents two irregular pits, apparently the alveoli of incisive germs. The fang of the functional canine contained in the intermaxillary bone is laterally compressed conical, and is an inch and a half in length. From the orifice of its alveolus it is strongly curved upward and backward, nearly on a line parallel with the curved palatal margin of the bone. The crown of the tooth was directed downward and outward; and at the base it is ovate in section, with the narrow end posteriorly ; and it measures six lines and three fourths wide, and three lines and three fourths transversely. A small portion of remaining enamel indicates this to have been thin and smooth. The small remaining fragment of the maxillary bone attached in the fossil exhibits at its broken margin the portion of an alveolus, situated an inch and three fourths behind the tooth contained in the intermaxillary bone. It has been about four lines in transverse diameter, apparently had a direction curving downward, forward, and outward from its bottom, and probably accommodated a true canine tooth, although the position is unusually far back, a necessary condition however in the Oumelops, from the distance to which the fang of the functional canine tooth extended backward. The margin of the hiatus between the alveoli indicated is subacute and concave ; and it measures one and three fourths of an inch in length. It is divided about the ia ial eat Rt a LEIDY’S DESCRIPTION OF REMAINS OF EXTINCT MAMMALIA. 167 middle of its course by the maxillo-intermaxillary suture, which descends at the side of the jaw parallel with the nasal border, and on the palate curves inward and advanees as far as the position of the posterior third of the orifice of the intermax- illary alveolus.

Canis primavus, Leidy. Proc. Acad. Nat. Sci., vii, 200. This name is proposed for an extinct species of wolf supposed to be indicated by a fragment of a skuil, discovered by Mr. Francis A. Lincke, in association with remains of Megalonyx Jeffersonii, Bison americanus, Cervus virginianus, Equus americanus, and Tapirus Hays, in the banks of the Ohio River, near the mouth of Pigeon Creek, a short distance below Evansville, Indiana. The specimen, which with others were kindly borrowed for my inspection by Dr. J. G. Norwood, of New Harmony, consists of the left upper maxillary bone containing the back five molar teeth, which are nearly entire except the penultimate. tooth. The fragment on comparison with the corresponding portion of the skull of the common wolf of HKurope, and its american congeners, differs only in being larger and in present- ing slight variations in the teeth, not however. greater than those found among different varieties, or perhaps even individuals of recent wolves. Certain naturalists may regard the fossil as indicative of a variety only of the Canis lupus, and of the correctness of such a view, an attempt will not be made here to decide. Naturalists have not yet systematized that knowledge through which they practically estimate the value of characters determining a species. What may be viewed as distinct subgenera by one will be considered as only distinct species by another, and a third may view both as varieties or races. In the use of these words, or rather in the attempt to define them, we go too far when we associate them with the nature of the origin of the beings in question. We know nothing whatever in relation to the origin of living beings, and even we cannot positively deny that life connected with some form was not co-eternal with time, space, and matter, and that all living beings have not successively and divergingly ascended from the lowest types. To return to a consideration of the fossil: the maxilla has the same form as the corresponding bone of recent wolves with which I have had the opportunity of cor- paring it. The infra orbital foramen, is vertically oval, directed forward, and is on a line vertical to the interval of the third and fourth molar teeth. The crown of the penultimate molar tooth is rather less concave posteriorly than in any recent specimens under inspection; and its antero-posterior diameter internally is greater in relation with the same diameter externally; or in other words the tcoth 43 168 LEIDY’S DESCRIPTION OF REMAINS OF EXTINCT MAMMALIA. internally is less narrowed than in recent wolves. It is also broader in the antero- posterior diameter when compared with its transverse diameter; and its basal ridge externally is a little more abrupt and is slightly crenated at the border. | The second and third molar teeth have their basal ridge internally a little better developed, which is also the case with the internal oblique ridge, descending towards the cusp anteriorly. : The principal measurements of the fossil, in comparison with those of the corres- ponding part in recent wolves, are given in the following table. ey a 2 Bl ctl aaduliie eras a Bo lege ee |e MEASUREMENTS. eS | SS sgh Noein cae g2| 22/28 | es | #8 | 2a 5 anes =e | * ar fs | esis [Fe | 22 [ge wi | O20 oO Eiiey ah ‘ f lines From base of crown of third molar to upper margin of maxilla, . é 25 | 24 | 213) 24 | 26) 31 From base of crown of fourth molar to upper margin of maxilla, . : 84 | 86 | 30 | 34 | 36 | 41 From back of last molar to canine alveolus, 5 eae aes A : 38 | 48 | 414] 422) 46 | 58 Antero-posterior diameter of first molar alveolus, 5 : ; ; 3 34, 33) 4 4 4 Do. do. of second molar tooth, . : c 6 : Male et OS ot 7 Do. do. of third molar, . : 6 ; : : Bel oye gs oak SB 5 Do. do. of fourth molar, . - 93] 13 | 124) 123) 13 | 16 Do. do. of fifth molar, . ; 5 : : UB Werte eel ah enews) theo) Transverse do. do. : : : 6 , 0 8 | 103) 11 | 103) 103) 113 Antero-posterior diameter of last molar, . 2 4 F 4 4. 43) 4 #| 423 ‘Transverse do. do. 4 Balt 7 re ail a 7 Plate 17, fig. 11.—Outer view of the fragment of the upper Jaw of Canis primevus. fig. 12.—Lower view of the same specimen. Ursus AMPLIDENS, Leidy. Proc. Acad. Nat. Sci., vi, 303. This species is founded upon a fragment of lower jaw and an upper molar tooth, which were discovered in association with remains of Megalonyx, Mylodon, Ereptodon, Equus americanus, Cervus virginianus fossilis, and Mastodon, ina ravine in the neigh- borhood of Natchez, Mississippi. The fragment of the jaw is of the left side; and it contains the last molar tooth, It has about the same size as the corresponding portion of the jaw of the common black bear (Ursus americanus), or of that of the grizzly bear (Ursus ferow) at an age when the permanent teeth have all protruded but are not yet worn by attrition. Its form also does not vary from what itis in the latter animals, except that it is more convex externally. The last molar tooth is intermediate in size to that of the black and the grizzly bear, but the form of the crown is more like that of the former than that of the latter. The specimen of an upper molar is the penultimate one of the left side. It has very nearly the same form as in the grizzly bear, except that the small cone in front of the outer pair of principal cones is almost as well developed as that behind them. LEIDY’S DESCRIPTION OF REMAINS OF EXTINCT MAMMALIA. 169 The slight variations indicated in the fossils might be considered as insufficient to characterise them as having belonged to a distinct species from the grizzly bear, but when we reflect upon the equally slight variations which exist in the homologous parts to the fossils in certain recent species of the genus, and recollect that the fossils in question were found in association with remains of the Megalonyx, &c., im a country never known to have been inhabited by the grizzly bear, we cannot help inclining to the belief that they belonged to a species distinct from the recent ones.

URSUS AMERICANUS FOSSILIS. Remains of the common black bear ( Ursus americanus) have on several occasions been discovered in association with those of extinct animals. Dr. Harlan* mentions an inferior maxilla, which was found in Big-bone Cave, Tennessee, in association with remains of the Megalonyx. The specimen, which is preserved in the collection of the Academy, contains none of the teeth, and it is unchanged from the original texture, except that it has lost a small portion of its gelatin. It is not improbable that the specimen may be of much later date than the Megalonyx remains with which it was found. Another specimen preserved in the cabinet of the Academy, consists of the left half of the lower jaw containing the canine and anterior two molar teeth of a species of bear, discovered in a ravine in the vicinity of Natchez, Mississippi, in association with remains of Megalonyx, Mylodon, Ursus amplidens, Equus americanus, Bison lati- frons, Cervus, &e. The specimen corresponds closely in its anatomical characters with its homologue of the common black bear. The bone is exceedingly friable, and is enveloped in a thick layer of compact peroxide of iron, in the same manner as the specimen upon which was established the Felis atrox,; and which was found in the same locality.

Besides several phalanges, the fossil specimens alluded to consist of several fragments of jaws and teeth. } A small fragment of the upper jaw (figure 17, plate 17) of the left side contains the fourth and fifth molars, which have the same form as the corresponding teeth of Procyon lotor, but are about one sixth larger. A specimen of a right upper canine tooth has the same size as in the recent raccoon, but is rather less compressed towards the subacute borders of the crown. (Figure 24, plate 17.) ia A small fragment of the right side of a lower jaw, (fig. 19,) rather larger than the corresponding portion of the same bone in the recent raccoon, contains the canine and the fourth molar tooth. The former has the same form, as in the recent raccoon, and is only a little larger. The latter‘tooth is not only larger than its representative in the recent raccoon ; but it has the inner posterior ridge of the crown continuous with the principal cusp and not terminating in a small cusp, and the tubercle at the outer posterior part of the base of the principal cusp is hardly developed in comparison with its condition in the recent raccoon. (Figs..19, 20, 21.) An apparent, isolated, inferior, third molar tooth (figs. 22, 23) of the left side has more nearly the form of the fourth one than of its homologue in the recent raccoon, and. it is also relatively larger in comparison with its associated succeeding tooth than:in the latter species. ‘The principal cusp and that developed from its base postero-externally are more distinctly separated than in the corresponding points of the fourth molar of the recent raccoon. The anterior heel also is less developed and that posteriorly is less exeavated than in the succeeding tooth of the recent raccoon, with which it is com- pared in preference to the corresponding one of the latter species. The size and form of the two fangs of the fossil tooth correspond with the same characters of the two alveoli for the third molar in the fragment of a lower jaw above indicated. In con- clusion it must be admitted that had this last, described tooth been found alone it would without hesitation have been viewed as a third inferior molar of Procyon lotor.

Am. Journ. of Science and Arts, 2d ser. v, 106. In association with the remains of Procyon priscus, just described, there was found a curious tooth, which Dr. Le Conte has supposed to be the left superior canine of a large ‘insectivorous animal. It is quite peculiar in form; and its affinities I am at present unable to determine. The tooth is compressed to a remarkable degree, and on the inner side for the greater part of its length is depressed, so that a transverse section except near the apex of the crown would be reniform. The crown is curved conical, and is most convex ex- ternally. Posteriorly its outer and inner surfaces are separated by a feeble ridge; and internally about half way towards the base it is furnished with an anterior and a posterior tubercle, of which the former is lower than the other. The fang at the broken border of the specimen is nearly half an inch broad and is less than two lines thick. In consequence of the deyeeysion of its inner wall, the pulp cavity has a curved linear form, thus c In its perfect condition the tooth has apparently been in theneighborhood of an inch and a half long, and the base of the crown measures five lines broad and one and three quarter lines thick.

XV.—On the Sandstone Fossils of Connecticut River. By JAmes Deane, M. D. Prior to the year 1839, the indications of organic life, co-existing with the sandstone deposition of Connecticut River, were exclusively confined to a few genera of hetero- cercal fishes. This rock was formerly supposed to be so destitute of animal remains, that when in this year I opened a new chapter of its organic history, my discoveries were treated with incredulity and neglect. But, after the investigations of twenty years that have resulted, itis known to be exceedingly rich in the imperishable materials of geological history. Very few indeed have any conception of the marvellous perfection of these fossil inscriptions, or of the multitudes of once living creatures whose existence they commemorate. During the vast sandstone deposition, it is presumed that animals whose instincts and organizations attracted them to littoral margins, were as numerous as their living representatives. The immense groups of birds embraced countless individuals who have inscribed upon the shores whereon they congregated their unmistakeable and instructive history. Most of the finest im- pressions have never been described, and the rich discoveries of late years, render a thorough revision of these fossils indispensable to a clear comprehension of the sublime truths they teach. Other inferior creatures existed in astonishing profusion during the sandstone period, and like the birds, have left the imprints of their feet vivid as upon the day they were made. The presumption is that they embraced as a class, animals no higher in the scale of organization than vertebrated reptiles. They were quadrupedal, and were grouped into several orders; Saurians, Batrachians and Chelonians. Of the saurian and batrachian orders I am acquainted with twenty species at least, and shall present herewith a notice of ten of that number. In one essential feature all these impressions concur, and that is, in the difference in magnitude between the anterior and posterior feet, the latter being about four times greater than the former. This distinctive character, and the diminutive size of the animals they indicate, appear to distinguish them into species, having their affinities in existing salamandrian or tailed Batrachians. The indications of Tortoises prove them to have been very numerous, but it is nearly impossible to detect specific differences. Their movements over soft mud re- sulted in ploughing up a trace or furrow by the solid armor of their bodies. In some instances the swinging movements of their feet are well preserved, and in rare cases the pedal imprints are also visible. | 174 DEANE ON THE SANDSTONE FOSSILS OF CONNECTICUT RIVER. Descending in the scale of organization, this rock has retained the foot-print of in- sects and crustacea with surprizing fidelity. Nothing in the strange history of the sandstone fossils, is more astonishing than the unrivalled perfection of the vestiges of these frail creatures. In this brief memoir I shall endeavor to portray some of these interesting hiero- elyphics of extinct existences. Fig. c, pl. 18,is an unimpeachable footprint of a bird, no other animal could impress it. Its analogies are unmistakeable. It is a left foot, the inner toe has two, the middle three, and outer four phalanges, exclusive of the nail, which is in exact correspondence with the feet of existing trydactylous birds. The triple-headed, or distal extremity of the tarso-metatarsal bone, is also unequivocally impressed. Naturalists may, if they prefer it, explain the origin of these impressions upon the hypothetical existence of such monsters as biped reptiles, but by the unerring laws of comparison, I have never hesitated for a moment to ascribe these footprints to birds. In this opinion I am sustained by a distinguished comparative anatomist, who, in relation to fig. c, remarks, “that some naturalists would call it reptilian, be- cause, according to their idea of cosgomony, birds did not exist in the new red sand- stone period, and there are some very distinguished naturalists who maintain this doctrine, but I call it the footprint of a bird, cosmogony or no cosmogony.” Fig. @ is quadrupedal, and is Batrachian. Each foot has four toes radiating forward, and the anterior foot is considerably more advanced than is usual. This is a very beautiful specimen of these delicate footprints. Fig. d has four toes, two diverging outward and two inward. They are thick and somewhat massive, and blunt at their extremity. Both the anterior and posterior feet are analogous as to form. Fig. e is an elegant and interesting example of the quadrupedal impressions, and the most diminutive ever seen. It is very perfect, yet it is difficult to comprehend the place to which the amimal who made them should be assigned. All the other quadrupeds move by alternate steps, but in this example both right and left feet fall simultaneously. There is no impression of a fore foot, but this is a common defect in delicate quadrupedal impressions, the impression of the fore foot not always being retained. It may be that the imprint of the anterior foot is obliterated by that of the posterior foot. The dragging of the foot from one step to another is distinctly pre- served. There were probably four toes. The surface upon which the creature moved is smooth as if polished, and no other would retain the imprints with such extraordinary fidelity. Fig. b is probably Saurian. It is exceedingly perfect. It is a hind foot with five heavy toes, if the appendage upon the left be considered asa toe. It has a Chirotherian aspect, but as it is a solitary example, and is separated from the fore foot, its true relations cannot be exactly determined. The fine preservation of its massive heel and toes renders it a very beautiful example of foot prints. DEANE ON THE SANDSTONE FOSSILS OF CONNECTICUT RIVER. 175 Fig. a, diagram A, pl. 20, isan undescribed species of quadrupedal imprints. The foot- prints are defective, being impressed when the mud was too soft to retain forms, but this condition was favorable to receive the trail of the animal’s tail, which is exquisitely preserved. This is a raré feature. Fig. 6, diagram A, pl. 20, is likewise new and undescribed, and is remarkable for the disparity of the anterior and posterior feet. The fore feet are very perfect, four thick but pointed toes radiate outward and somewhat backward. The posterior feet are comprised of four long, slender toes, lying nearly parallel, and the feet are divergent. Right and left feet widely separated. The foregoing species of quadrupedal imprints have never been figured or described. Those which follow are copied from drawings made by myself and published in the Journal of the American Academy of Arts and Sciences a few years since. They are inserted here for comparison, although a simple outline of a foot can convey no adequate idea of its organization. Fig. a, diagram B, pl. 20, is remarkable for its peculiar symmetry. Four thick, tapering toes radiate forward, and in the hind foot the impression of the heel is pro- longed backward to a considerable distance, and is broad and flattened. The fore foot - is planted a little in advance and a little outward of the hind foot. Fig. }, diagram B, pl. 20. The hind foot consists of three thick, pointed toes, widely spread, and a short toe pointing inward. The heel is projected backward, and termi- nates in a rounded extremity. The anterior foot is not conformable to the posterior. Four toes, two pointing forward and outward, and two outward and backward. In birds the foot points inward without exception ; in quadrupedal impressions it diverges outward in every instance I have ever seen except this. The hind foot inclines slightly inward. Both examples upon diagram B are exquisitely beautiful and perfect. Fig. a, diagram C, pl. 20, is a series of very delicate foot-prints. Toes four, long and slender, and drag from one step to another. Impression of anterior feet not retained. Fig. 6, diagram C, pl. 20,is probably Saurian. Toes have a chirotherian look, thick and massive. Feet divergent. The fore foot planted near the hind, sometimes partially obliterated by it. Stride very great. Fig. d, diagram C, is probably analogous, and both, with the exception of the appendage upon the side opposite the thumb, have a striking resemblance to fig. 0, pl. 18. The remaining fig. c, diagram C, pl. 20, is probably Batrachian ; toes four, feet divergent, impressions of anterior feet not retained. The impressions upon pl. 19 are of recent discovery, and the obscurity of their origin is in proportion to their beauty and extraordinary preservation. Nothing of the kind has hitherto been described or even discovered. Fig. a of this plate is remarkable for the geometrical symmetry and perfection of the dotted impressions, which are arranged in ON each a reproduction of the other. ~ 176 DEANE ON THE SANDSTONE FOSSILS OF CONNECTICUT RIVER. I think in the present state of science it is impossible to explain the origin of this elegant fossil. If the accuminated bodies that constitute the various lines of impressions be not due to the deciduous fronds of plants, they must be taken for the dermoid pro- tuberances of some animal. ‘There is not the slightest evidence of a compressed stem of a coniferous or other plant, which should certainly be the case in so perfect a specimen; and moreover, upon the superior or superincumbent stratum, the imprint is reversed ; it is a cast, and this, it appears to me, is conclusive evidence against a vegetable origin. Ihave drawn this beautiful fossil with excessive care, for it is the most difficult puzzle I have ever encountered, and I must leave it to others more com- petent than myself 10 determine its origin. The reader who will take the trouble to analyze the various line of impressions, wili find a corresponding number in each repe- tition. Thus in the unbroken row running obliquely upward from left to right, there are invariably fourteen of the protuberant points, and in each other line, when re- peated, is consistent, both as to number and arrangement of the geometrical lines of elevations. The remaining figures upon this plate are probably foot-prints of a class of creatures not higher in the scale of organization than the articalated division of animals, and a few observations perhaps may assist in deciding upon their origin. I rely more upon the fidelity of the drawing than upon any descriptions to convey exact ideas. : Fig. 7, pl. 19, is the simplest form of these linear imprints. It is a single set of straight, slender, parallel feet, planted in regular succession. Fig. f. The set is also single, feet slightly divergent, and terminate in an enlarge- ment or depression, caused apparently by the momentum by whicli the creature moved. Fig. c. The two rows upon the left are identical with those of fig. f but there is also an additional row of impressions upon the right, the terminations of which are not excavated. In fig. 6 the impressions are identical with fig. c¢, except that the order is reversed. In fig. h two sets of feet are exquisitely preserved. The irregular or odd number of feet may perhaps be explained upon the hypotheis that the creature was moving upon the bottom of the water, and by floating used a part only of its organs of locomotion. This conjecture is sustained by the fact that the rows of impressions sometimes appear and disappear abruptly upon the surface, and are both preceded and succeeded by delicate prolonged lines, caused by dragging of the feet. Fig. g displays two rows of linear feet, and are very fine indeed. The entire length of the original impressions is fifteen inches. Fig. & shows a row of parallel linear feet, and corresponding rows of lateral bulbous impressions. Fig. d also shows the central or parallel rows, and two corresponding lateral rows of curved feet. Ree te a =e ee ean, is ; t DEANE ON THE SANDSTONE FOSSILS OF CONNECTICUT RIVER. 177 Fig. ¢ exhibits the trail of the body, with lateral feet. These extraordinary fossils occur upon surfaces as smooth as polished marble; no other would receive, much less retain such delicate impressions with such fidelity. To explain their obscure meaning I have sought the assistance of several gentlemen distinguished for their scientific attainments, and it gives me pleasure to subjoin their opinions to these meagre descriptions of my own. Prof. Leidy considers the impressions &;, d, 7, /, c, and 6, to be the tracks of insects and crustacea; g and e those of worms; and a, from its remarkable uniformity, to be rather a vegetable than an animal impression. Prof. Gray is of opinion that fig. a represents leaf scars of some plant like a tree fern. Prof. Wyman is of opinion that fig. a is a vegetable impression, and that the other impressions upon this plate are due to articulate animals, insects or Crustaceans. Prof. W. B. Rogers is of a similar opinion as regards fig. a, yet he remarks that this is but conjecture, and that we are without any guide as to MD might be esteemed a probable interpretation of this mysterious inscription. Prof. Dana can refer fig. @ to nothing but a plant, the prominence being the traces of leaves, probably coniferous; still it is not like any known coniferous plant, ancient or modern. Upon the remaining figures of pl. 19 he offers the following valuable re- marks: “The delicate linear tracks must be made by an articulate animal. They can hardly have been made by annelids (excepting e and g of which there is doubt), and may have been made by Crustaceans or insects, perhaps water insects. I should incline to say Crustaceans. Among the tribe of this class they may have been either Entomostracans, Isopods, Macrourans, or small species of Anomourans. Isopods have too small legs and pointed claws to make so large a track as 4, and they would not make the two distinct series of this figure, or a track with three impressions as in ¢, The legs spread from the longitudinal axis, and do not point forward asin 7. Still it is possible that d and & might have been made by an Isopod, the bent form of the track in this case being due to the fact that three joints of the leg, pressed on the mud in the progress of the animal. There is a small tribe of Crustaceans near the Isopods, which I have called Anisopods, in which the two anterior feet often have large claws, and are projected forward in front of the head, and such an animal might make marks with these claws like J, but I should think they would be likely to be less regularly, or even continuous lines.” “The Entomostracans may have been tracking the mud ; but so small species of that group have usually very thin or slender feet, commonly more or less foliaceous for swimming.” “T should therefore be inclined to refer the triple and quadruple track to small Anomourans. The two more central tracks, where there are four, being made by the 178 DEANE ON THE SANDSTONE FOSSILS OF CONNECTICUT RIVER. anterior claws; and the one where there are three to the claw of one side, for it is very common for one claw to be larger than the other, and sometimes the difference of size is exceedingly great.” “T cannot say that g and e are Crustaceans, as some large Isopods have legs that would make as strong impressions. But in Isopods the three anterior of the seven pairs of legs are directed obliquely forward, and the four posterior pairs obliquely backward, so that there would hardly be with such animals the exact uniformity of direction these tracks present.” In bringing this paper to a conclusion, I must here express my acknowledgements to the gentlemen who have so politely responded to my request for information. I am also under peculiar obligations to Roswell Field, Ksq., who is the discoverer of all the original specimens of the two plates and those of the diagram A, and who kindly loaned the specimen. The estate of Mr. Field is situated at Turner’s Falls, and by his sagacity and activity he has been very successful in developing the history of these sandstone fossils. He has made many very splendid discoveries. ‘The fossils that constitute the originals of the plates and diagrams are exclusively from Turner's Falls.

Kane, U.SN., in his first and second expeditions to the Polar Regions, with descriptions and remarks. By Eras Duranp. I have brought together in the following enumeration all the plants collected by Dr- Kane at the stations of his two voyages, the whole belonging to the western coast of Greenland, and nearly to the same geographical zone. These stations were, for the first voyage, (1850 and 1851,) Sukkertoppen, Holstein- ' borg, Egedesminde, Disko, Upernavik, and Wolstenholm, between the 64th and 76th north parallels; and for the second, Fiske Fiord, Sukkertoppen, N. Proven, Uper- navik and the different stations of Smith’s Sound as far as 81° N. latitude. The first collection was in pretty good order, but the second had suffered much from the peculiar hardships attending the last period of this eventful expedition, in which Dr. Kane’s fortitude and devotion to science were so signally manifested. Surrounded with difficulties of every sort, and threatened by the impending danger of starvation and death, amid the drifts, disruptions and other impediments of a hyperborean cli- mate, he did not hesitate sacrificing the useful articles of comfort and self-preservation, to make room in his luggage boxes for as many of his scientific collections as he could pack in them. Thus was the best portion of his botanical specimens preserved to science, after suf- fering much, as it may be imagined, from the inclemency of the weather, and the hardships of a long and perilous voyage back to the United States. But for the zeal and self-denial of his comrades, and especially of his surgeon, Dr. I. I. Hayes, his co- laborer in the scientific field, Dr. Kane is pleased to acknowledge that he could never have undertaken their transportation. Under these circumstances I have experienced great difficulty in determining seve- ral specimens,—difficulty arising not only from their damaged state, but also from their occasional incompleteness, some being just blooming, others in a fruiting condi- tion, others again wanting some of the essential characters. To these disadvantages I must add the want, in several instances, of books of reference, and of authentic spe- cimens for comparison. . When I attempted the task of determining these collections, I relied much, I con- fess, on the assistance of a learned and more experienced friend, Professor Asa Gray ; but, owing to the pressure of his occupations, I have not been able to secure his val- uable services to the extent of my anticipations. I am, however, greatly indebted to him for hints and remarks that have been very useful to me. I am under peculiar 180 PLANTA KANEANZ GRONLANDICA. obligations to Professor Torrey for the determination of the Gramineae, and hisassist- ance in some of the most perplexing genera; and also to my friend Thomas P. James, Hsq., for the entire enumeration of mosses, Hepaticee and Lichens. Iam most happy to take this opportunity to render to these three gentlemen my sincere acknowledg- ments for their great kindness. Laying aside the consideration of the lost packages, Dr. Kane’s collections are yet among the richest and most interesting ever brought by Arctic and Polar explorers. They not only afford a considerable accession to our previous knowledge of the vegeta- tion of Northern Greenland, but they develop facts of some importance in a physico- geographical point of view :— First—By exhibiting, throughout the range of coasts between the Arctic and Polar circles, no perceptible change in the number and identity of the species therein col- lected ; thus establishing, as far at least as Greenland is concerned, that the third or Polar zone of Sir John Richardson* might as well begin at the 67th as at the 73d N. latitude. Secondly.—By the reappearance, beyond the limits of Smith’s Sound, of Hesperis Pallasti and Vesicaria arctica, in a perfect fruiting state—two plants belonging rather to the milder regions of the Arctic zone, and which have never been found yet, I be- lieve, in the higher intervening points. Both these plants belonged to a scanty collec- tion of eight or ten species, made late in the season, on the newly discovered lands of Washington and Humboldt, on the very verge of that mysterious Polar sea which Dr. Kane’s expedition had the good fortune to espy and see free of ice as far as the eye could reach. Such a fact indeed, although limited to two species, seems to indicate peculiar isothermal influences, depending either on warm currents, greater depth of water, or actual depression of our globe at its poles. Another remarkable feature of Dr. Kane’s collections is, that, dividing into two equal parts the whole extent of coasts visited by him, and each section presenting about the same number of stations at which herborizations were made, the northern section, from Upernavik to Washington Land, has yielded more dicotyledonous plants than the southern, from Fiske Fiord to 73°; and Smith’s Sound alone, only three de- grees in length, has proved nearly as rich. (See Table No. 1.) ; These unexpected results show that the Polar zone cannot properly be compared with the Alpine regions of the more temperate climates. The uninterrupted action — of light and heat, during the whole period between the rising and setting of the sun which marks the day or summer season of the poles,—a purer and damper atmosphere, aided, perhaps, by a greater accumulation of electric fluid, &c.—must necessarily and more promptly (in the lowest levels) actuate and perfect the vegetation, not only of “See Appendix to Searching Expedition, London, 1851, p, 319 and following, PLANTA KANEANA GRGENLANDIC. 181 plants inured to those climates, but also of those the seeds of which have been trans- ported hither from milder regions by currents, migration of birds, or other causes. Unlike the snow-capped and barren summits of the Alpine regions, at all times des- titute of verdure, itis probable that vegetation is permitted toextend to the very pole itself, wherever it meets with proper soil, favorable solar exposure, and protection from the blasts of winds. | The southern extremity of Greenland, from Cape Farewell to Sukkertoppen, has been well explored, and found to possess nearly the same climate as Labrador, with an almost identical vegetation. E. Meyer, in his Plante Labradorice, (1830,) enume- rates 224 phzenogamous species, the greater part of which are indigenous both to Lab- rador and to Greenland. Professor Giesecke, who resided several years in Greenland, for the express purpose of studying its Natural History, published in Brewster's Ed- inburgh Encyclopedia (1832) an enumeration of 171 phzenogamous species, with a long list of Cryptogams, amounting to no less than 231 species, all indigenous to that island. From the two above works, and from all the other sources to which I have had access,—De Candolle, Torrey and Gray, Hooker, Brown, Richardson, Hornemann, Steudel,—for Cyperaceze and Graminez, &c., I have compiled the following Table No. 2, which presents an amount of 264 phzenogamous species, belonging to 109 genera and 36 families. This apparent richness of the Greenland flora is, however, confined to the extreme southern point of the island; for, from Sukkertoppen to a few degrees higher, it is found to have lost already eight or ten families; and from Upernavik, 73°, to the out- let of Smith’s Sound, it is reduced to twenty families, by the entire disappearance of Violacee, Oxalidacee, Holoragee, Umbelliferee, Cornacee, Lentibulacee, Primulacee, Gentianacee, Boraginacee, Labiate, Plumbaginacee, Plantaginacee, Betulacee, Coni- Sere, Orchidacee, and Melanthacee. Notwithstanding this prodigious decrease, the column headed North Greenland from 73°, in Sir John Richardson’s Statistical Tables, will be found, by the accession of 27 other species from Dr. Kane’s collections, now to be raised—from 49 phzenogamous species allotted to that region by the eminent English botanist—to 76; which is a gain of fifty per cent. . The following species are to be added to Richardson’s column of North Greenland from 73° :— Ranunculus Sabinii? | Dryas octopetala. Hieracium vulgatum. 1 Salix. Hesperis Pallasii. Alchemilla vulgaris. Vaccinium uliginosum 2 Eriophorum. Vesicaria arctica. Potentilla frigida. Pyrola chlorantha. Agrostis canina. 3 Draba. Sedum rhodiola. Diapensia Lapponica.

XVIL—A Commentary on the Synopsis Fungorum in America Boreali media degentium, by L. D. de Schweinitz. Bythe Rev. M. J. Berxerry, M. A., F.L.S., and the Rev. M. A. Curtis, F. A. A. A. S. With a view to place the Mycology of the United States on a firm and stable foundation, a careful examination of most of the species which still exist in the Herbarium of Schweinitz has been instituted by the authors of the present Memoir. Free access has been also had to the numerous authentic specimens in the Herbarium of Sir Wm. Hooker, and Prof. Torrey has kindly presented us the collection given him by Schweinitz. About a fourth of the species have passed under review, and as the examination of the remainder must necessarily be a work of time, we think it best to publish the present by way of instalment. When the whole has been reviewed, we hope to be in a position to give a complete Mycology of the United States, for which we have immense materials. As Schweinitz did not possess types of the greater part of the Kuropean species, it was impossible that he should not have made many mistakes in the determination of species; but though we have been compelled to differ frequently from him in his diagnoses, the species which he has published as new, with few exceptions, still hold their place in science, and present numberless points of interest as regards structure and affinity. He was, however, very far from exhausting the treasures of the American forests. We have in our possession a host of new species, equal in interest to those which first gave so high a character to American Fungi; and a review of these authentic specimens has, in only a very few instances, compelled us to change our nomenclature. There will be no longer delay in the publication of the remainder of our commentary, than unavoidable circumstances may necessitate. ** When our paper upon the Exotic Fungi of the Schweinitzian Herbarium (see Journ. Acad. 11. p. 277) was written, we had not ascertained from whom the Surinam species were procured, there being no recognition of the collector upon the tickets. We have since learned that the collection was made by Dr. Hering, now a distin- guished Homoeopathic Physician of Philadelphia. Dr. Schweinitz had evidently intended to commemorate this gentleman’s services in Natural History by naming for him the genus since published by Berkeley under the name of Hyporyssus. (See _Kxot. Fung. No. 15.) Herrera is now devoted by Agardh to a genus of Algz. 206 BERKELEY AND CURTIS'S COMMENTARY 100. AGaricus siccus, Schwein.! This resembles very closely Marasmiws hama- tocephalus, Mont., but the upper half of the stem has a transparent appearance, and there is a cottony tuft at the base.

Perhaps this may be a sexual character. D. punctatorugosa Blanch. having the front transversely elevated, must belong to this group. Blanchard, however, describes it as “breviter ovata,” while according to Burmeister, who does not mention the form, the anterior tibize are acute- ly 3-toothed. IV. 8.

On comparison, however, several differences may be found : the thorax is not so short, and the posterior angles are less obtuse ; the clypeus is rounded in an arc of a circle, and more strongly margined; the upper tooth of the anterior tibie is almost entirely obliterated. 15. D. truncatula, oblongo-ovata, convexa, picea, capite confertim punctato, hemihexagono, clypeo tenuiter marginato, antice truncato, sutura frontali profunda, thorace sat dense punctato, lateribus ob- lique zqualiter rotundatis, angulis posticis obtusis rotundatis, elytris grossius punctatis, tricostatis, tibiis anticis tridentatis.

This species is by its sculpture related to D. punctata, but the thorax is more coarsely punctured, and the costz of the elytra are marked with a very strong row of punctures, which with the punctures between the geminate rows are furnished with short but stout suberect hairs: the punctures of the thorax and those near the frontal suture also emit hairs. The la- brum is more deeply emarginate than in the other species, but the under part of the claws is as long as the upper, the thorax has a narrow apical membrane, and all the other characters are of this genus. 22.

Long. -28. A dead specimen found at Vallecitas, San Diego County, California. Resembles in its proportions D. angularis, and probably belongs to Div. IV., but differs greatly in the sculpture of the elytra; the punctures of the first interstice are confused, those of the other intervals between the coste, are represented by rows of punctures equal in size to those of the regular rows but more distant; the coste are without punc- tures. The terminal tooth of the anterior tibize as usual is long, the others are almost obsolete : the lower part of the ungues is acute, and hardly shorter than the upper; the posterior tibiz have more long hairs than in D. angularis. 272 LE CONTH.—SYNOPSIS OF THE B.

Long. ‘44, One specimen, Fort. Yuma, Colorado River, California. This insect has the appear- ance of a large Aphodius. The spaces of the elytra which represent the cost are marked each with a row of small punctures. The under surface is very coarsely punctured, and the punctures have short yellowish hairs. The pygidium is very coarsely and the propygidium densely punctured, the latter is transversely elevated, or rather broadly sulcate near the apex. The posterior tibie at the outer apical angle are armed with three longer spines. 26.

The form is that of most Diplo- taxis, but the spiracles of the propygidium are prominent as in the last species. The mandibles are less prominent than usual, and in fact hardly visible. The propygi- dium and pygidium are sculptured as in the preceding; the tooth of the claws is per- pendicular, and not large. C. Spurie. 27.

The mandibles are more prominent than usual, and bent downwards, so that the ligula is covered by them. The pygidium and propygidium are very coarsely punctured, and the latter has the usual transverse impression near the apex. The apical fovese of the thorax are half way between the middle line and the angles, the others are near the side, and at the greatest breadth. 28. D.

The under surface is coarsely punctured, more sparsely at the middle of the metosternum ; the punctures support very short hairs. 5. SERIC A. This group is readily known from all the others by the labrum being connate with the clypeus, and very frequently indistinct ; in addition, the anterior coxe are conical and prominent ; the abdominal segments are hardly connate, the penultimate dorsal and ventral are separated by a straight suture, and the stigma is concealed in the anterior angle. ; The genus Serica M’Leay, the only one found in our territory, belongs to the divi- sion of genuine Serice, having the posterior coxe dilated, and the ligula corneous and connate with the mentum ; it may be thus separated into two groups: | A.

Herbst in the description insists so strongly on the “ flachliegenden Harchen,” that I have considered the species as known to him. The characters given by Burmeister are relative, except that he states the anus to be tes- taceous. It is so in all the specimens before me, but sometimes too the whole abdo- men is of the same color. The abdomen of the female is large and- convex, with a few bristles at the middle of the four anterior joints; that of the male is more com- pressed, with numerous spine-like bristles arranged in rows each side of the middle. 7. DICHELONYCH &. A small group, confined to the American continent, and of which the well known genus from which it derives its name is the sole representative within our territory. As a group, it is distinguished from foreign groups among the Melolonthide with prominent conical anterior coxe, free labrum and abdominal segments, by the ligula being connate with the mentum, the labrum large, vertical and deeply emarginate, and by the sternum not being protuberant. ‘The thorax as in Diplotaxes has a nar- row apical membranous margin. With regard to the position of the group, Lacordaire forms with it the passage from the Sericoides to the Macrodactylides ; from the latter of which it differs according to his classification by the fifth ventral segment not being larger than the others. I find, however, in Macrodactylus that the difference in size of the segments is byno means obvious, and I am inclined, therefore, with Burmeister to rank the present as a sub-group of Macrodactylide, verging indeed by the freely moving and prehensile claws to the Hoplide.

Middle States and Lake Superior. When the hair of the thorax has been removed, as is sometimes the case, this species may be known by the very dense, but not fine punctures of the thorax, the base of which is wider than the apex, and the-sides angu- lated at the middle. There appears to be a variation in the form of the basal angles, sometimes they are subacute and moderately prominent, sometimes rectangular, and sometimes obtuse ; they are never very acute and prominent as in D. elongata. It is possible that by comparing specimens from different localities several closely allied species here confounded together may be separated. One female from Maryland has the posterior angles more prominent, and the elytra of a dull brownish bronze color. The thorax appears more coarsely punctured, but it is unsafe to propose a new species upon this single specimen. 5.

Burmeister places this as synonymous with D. linearis ; my specimens are however clearly different, not only by the dark colored antenne, but by the more strongly margined clypeus, and by the more coarsely and less densely punctured thorax; on each side of the disc anteriorly, near the lateral fovea is an indistinct space which is less punctured; the sides are less angulated, and not at all sinuate behind. The specimens were found floating in the lake, and had lost nearly all the pubescence; from the appearance of what remains on the side of the thorax, I believe that the hair was coarse and probably dense as in D. linearis. Kirby does not mention this character, but it may have been lost in the alcohol in which the specimens were preserved; the hair of the under surface, being better protected, has been preserved in both his specimens and mine.

In this group I have comprised two genera, containing species of small size, living upon flowers. Although differing remarkably in appearance and characters, not less from each other than from all other genera of the tribe known to me, I have been induced to associate them together on account of the following characters, which they have in common. The anterior coxse are large, conical and protuberant ; the abdomen is very small, -and the sutures between the anterior segments are nearly effaced; the last segment is conical, free, and larger than usual. The parapleurse are narrow. ‘The claws are diverging, with a very short bisetose onychium; the posterior tibia: are armed with two spurs, but the anterior tibiz have no spur. Lastopus Lec. Clypeus rotundatus, valde concavus, ad apicem subemarginatus ; mentum parvum lineare; pedes postici incrassati ; ungues simplices elongati. Body oval, elongate convex, fringed at the sides and beneath, and on the legs with very long hairs. Head small, eyes large, hardly emarginate, clypeus rounded, deeply concave, slightly emarginate at tip, separated from the head by a deep transverse concave line. Mouth small, labrum and mandibles invisible ; mentum small, narrow, not larger than the base of the maxilla. Palpi slender. Antennz 9-jointed ; first and second joints thick, hairy ; four following small ; club three jointed, small. Thorax rounded on the sides, convex, narrower in front. EHlytra elongate, convex, partly covering the pygidium. Legs strong, hairy; anterior tibize subtridentate; middle tibize conical, with a crown of spines externally at the middle, and two terminal EN en | ee MELOLONTHIDA OF THE UNITED STATES. 283 spurs; posterior thighs very large, posterior tibie like the middle ones, but much thicker. Tarsi twice as long as the tibia, slender, with verticillate hairs at the articu- lations ; last joint with two long terminal hairs above; ungues long, slender, diverging onychium hardly visible, bisetose. I have given to this genus an unpublished name proposed by Dejean for Aclopus Erichson, to which genus this seems to bear a remarkable resemblance in form. The labrum and mandibles are however entirely invisible. I regret that I cannot give the position of the abdominal stigmata, but conclude that they must be very much as in the next genus. 1. L. ferrugineus, valde elongatus ovalis, nitidus ferrugineus, capite punctato, clypeo parce punctato, thorace minus dense inzequaliter punctato, ad basin levi, antice subcanaliculato, lateribus longe fimbriatis, elytris parce punctatis, punctis subseriatis extrorsum confusis, breviter parce pilosis, margine fimbriatis ; subtus et pedibus parce longe pilosis. Long. -19. Ringgold Barracks, Texas. We owe this most interesting addition to our fauna to the scientific industry of Mr. H. Haldeman. The genus will be readily recognized by the narrow oval body, fringed with long hairs, and by the long hairs of the legs, and the thickness of the posterior femora and tibize. Oncervus Lec. Clypeus duplex ; mentum trapezoideum barbatum ; pedes postici incrassati ; ungues fissi. The only species of this genus known to me is the smallest of the tribe that I have seen, and presents such a curious assemblage of characters that I am at a loss which to select. The form might be compared to a Hoplia, oblong and more narrowed in front ; the. body is shining, sparsely hairy, especially beneath. The head is narrow with convex prominent eyes, the clypeus prolonged, flattened, parallel on the sides, rounded slightly at the apex and incised each side, with a deep transverse concave suture between the incisions; the frontal suture is straight and deep, running between the antenne. which are short; the first and second joints are thick and hairy; then follow four small joints, and then a small three-jointed club concave outwards; the mentum is large, flat, trapezoidal, wider in front, with long scattered hairs; the bases of the maxille are long, slender and prominent each side of the mentum ; the maxil- lary palpi are slender, penultimate joint small, last joint elongate, slightly oval; labial with the last joint longer than the preceding, slightly oval. Thorax wider than the _ head, rounded on the sides, and gradually narrowed in front, Llytra a little wider than the base of the thorax, oblong, slightly flattened on the disc, with the sutural stria fine. Pygidium slightly exposed. Legs strong, hairy, anterior tibize subbiden- tate; middle tibize conical, moderately thick, with a crown of short spines at the _middle externally, and two apical spurs. Posterior thighs very large, tibie thick conical, with a crown of spines externally about one-third from the tip, and two apical 284 LE CONTE.—SYNOPSIS OF THE spurs. ‘Tarsi slender, longer than the tibize, with verticellate hairs; ungues diverging, armed with a tooth so long that they appear cleft; onychium short bisetose. | 1.

Long. -13—-16. Found at Vallecitas, San Diego Co., California in April, on flowers of a composite plant. I can find no sexual characters in the specimens collected. By examination I find the abdominal stigmata situated in the dorsal inflexed portion of the ventral segments; the last pair I cannot detect, since the margins of the ventral segments are thin and reflexed above the dorsal surface, so as to produce a concave surface, in which the posterior pairs are concealed. 9. HOPLLAL. © This division is known among those having prominent conical anterior cox by the ventral segments being connate, the sixth indistinct or even invisible; by the large parapleure ; the tibize without terminal spurs or at most with a single very small one, and by the ungues being chelate (7. e. capable of being folded against the last joint of the tarsi,) not divergent, unequal and without any onychium. In this division, though not in any American form, is found a modification of ligula not seen or only exceptionally in any of the preceding tribes; the ligula is membra- nous, and not connate with the mentum : by this character, found in Pachycnemis and allied genera, the passage to the following group is most naturally made. The only genus found in our country, and in fact the only one found outside of Southern Africa, is Horta Illiger. A. Unguis minor anticus et medius duplo vel plus duplo brevior. 1.

The posterior tarsi are broken, so that I do not know whether the claw is simple or bifid. I have excluded H. helvola, as asynonym, since the description mentions linear scales on the elytra; it seems to me rather to be the variety of H. trifasciatawith almost uniformly colored elytra, and this view accords with the measurements given. H. monticola, Mels. Proc. Acad. Nat. Se. Phila. 2, 141, I have failed to identify. The dimen- sions given are 32 lines by 13, which are the proportions of H. mucorea. From notes sent me by Dr. Melsheimer, it would seem to differ from both that species and H. modesta. The color is brownish testa- ceous, the head and thorax are darker, the latter clothed with short rufous hairs and sprinkled towards the sides with whitish scales, ‘the sides are somewhat dilated beyond the middle, slightly incurved posteriorly, sub- rectilinear from its widest portion to the tip; elytra hardly wider at the base than the base of thorax’, more than twice as long as the thorax, clothed with short rufous hairs, two obsolete longitudinal raised lines near the middle, pygidium clothed like the elytra, venter covered with small whitish scaly hairs. ‘ Anterior tibie bidentate ; inner middle claw less than one half the size of the outer one: posterior claw entire.’ Pennsylvania, in Adams County. Should the last character be erroneous, it might be referred to the light colored specimens mentioned under H. modesta. 10. GLAPHYRI. A group placed by Erichson among the laparostict Scarabaeidae, but in which, as Burmeister has shewn, the position of the abdominal stigmata ceases to be of value as a primary character. As a group of Melolonthidex, this may be readily recognized by the labrum being at the end of the clypeus, and in the same plane ; by the projecting mandibles, the wide parapleurze, and the not connate six-jointed abdomen. The ungues are slender, equal and diverging. . The only genus found in the United States is Lichnanthe, which differs from Amphicoma chiefly by the deeply emarginate labrum. LiconantuEe Burm. 1.

In outline it is close to U. superbus, (nobis,) but is more rotund. It is more shallow in the cavity, much thicker in the anterior portion, and in the teeth they differ much. The cardinal teeth of U. swperbus are long and lamellar, while in Hainesianus they are short, thick and conical. The nacre is not so pearly in the latter.

Shell with two wings, connate before and behind, smooth, triangular, compressed, very inequilateral, rounded before and obtusely angular behind; substance of the shell rather thick; beaks rather prominent, with a few very small undulations; ligament rather long and concealed; epidermis greenish brown with two lines in the posterior slope, obscurely rayed, smooth and shining; umbonial slope obtusely angular; marks of growth distant and indistinct; cardinal teeth long, lamellar, oblique and double in both valves, but more defined in the right; lateral teeth long, very lamellar, slightly curved and joined to the cardinal tooth; anterior cicatrices distinct, the larger one having a deep sinus on the superior part ; posterior cicatrices very indistinctly marked, confluent; dorsal cicatrices well marked in the cavity of the beaks; cavity of the shell very shallow; cavity of the beaks very shallow and obtusely angular; nacre delicately salmon colored and iridescent. Remarks.—This belongs to a natural group of symphynote species of which U. delphinus may be considered the type. It is, however, not so wide, nor has it so high a wing posteriorly. It differs also in the teeth, the cardinal teeth being more lamel- lar and divided into two or more parts, while those in the delphinus are flattened and erenulate or granose. The lamellar teeth of delphinus are nearly straight, or entirely so, while those of Howsei are more or less curved. The specimens were all more or less injured, and particularly in the wings. I owe this, with many other species from Siam, to the kindness of Mr. W. A. Haines, who obtained them from Dr. House, now a resident of the city of Bangkok, and to the latter gentleman I dedicate this fine species with pleasure. Unio turevs.* PI. 24, fig. 4.

It may be distinguished from it by the gravidus being more inflated, by its yellow epidermis and bluish white nacre. The swperbus is a thicker shell, and the teeth are less lamellar and the cardinal teeth are rather shorter. All I have seen are delicately salmon colored, while the ten or twelve specimens of gravidus before me are allwhite. The greater transverse diameter is much nearer the centre of the shell, and the outline approaches more to the rotund. The three rays on the posterior slope are very distinct and beautiful in the young specimens. The lunule is in several of the specimens remarkably large. The cardinal teeth in right valve are disposed to curve upwards. Mr. Haines received this species, with many interesting ones, from Dr. House, of Bangkok, Siam. Unio inornatus. Pl. 24, fig. 6.

Remarks.—There were about a dozen of this species submitted to my examination by Mr. Haines, differing very much from each other. Some of them are tuberculate nearly over the whole surface, while others are almost entirely without tubercles. In this it agrees with U. corrugatus, Retz, and U. Tavoyensis, Gould. In outline it closely approaches U. Javanus, (nobis,) but is a rougher shell and the folds on the posterior slope are coarser. In some specimens the tubercles about the beaks resemble those of U.

Remarks.—In outline and general appearance this interesting species resembles the young of Unio alatus, Say. It may at once be recognised to be different by the numerous small folds—which are visible in the interior as well as the exterior—as well also by the peculiar number and place of the lateral and cardinal teeth. It would naturally follow, as a plicate shell, U. Micklinianus, (nobis.) The most remarkable feature in this species is the possession of three lateral teeth in the left valve. In the eight specimens before me the three teeth are recognised. In all of them the upper division is smaller than the two lower ones, and the upper one of the two of the right valve is also always smaller. The cardinal teeth are remarkable for being double in the right _and single in the left valve. Some of the specimeus are enlarged over the umbonial slope, immediately behind which there is a slight emargination at base. The enlarge- ment is owing probably to sexual difference. Unio tumiputus.

The folds are small and numerous, and may be seen on the inside of the valves in the region of the beaks and the posterior slope. ‘The size of hwmilis is about that of U. acutissimus, (nobis,) but is not so angular on the posterior margin, and the folds are smaller and more numerous.

In outline it very much assimilates to crispatus, but it differs very much in having few folds, in being highly polished, less angular at the posterior margin, and more rounded and inflated on the posterior slope. ‘The younger specimens have a strong resemblance to humilis, but are more polished, have fewer folds and are thicker. On the umbonial slope near the 76 298 LEA’S DESCRIPTIONS OF EXOTIC GENERA apex, there are three or four granules ina line. There are five specimens before me; two adult, both of which I suspect are females, and three about half grown.

Remarks.—There were two specimens and an odd valve only of this species among the Siamese shells brought by Dr. House. In general form and characteristics, it is exceedingly like U. Cailliauduw, Fer., from Kgypt, and might at first sight be taken for that species. It is, however, entirely different in the cardinal teeth as to form, size and condition. Our shell has lamellar teeth, double in the right and single in the left valve, while the Cailliaudu has short, thick teeth, double in both valves. Both my specimens of Cailliaudiw have minute rays over the whole disk, while sagittarius seems to be entirely without them. It must be remarked, however, that the speci- mens are by no means perfect. Neither of them have the beaks perfect enough to ascertain if they have been plicate. In outline this species has also some affinity to U.

Reemarks.—This very beautiful Siamese little species was first sent to me by Dr. Ingalls, of Greenwich, N. Y. Several specimens of different sizes have since been put into my possession by Mr. Haines, to whom I am indebted for so many new species from this part of Asia. On receipt of Dr. Ingalls’ specimens I had some doubts of their being a variety only of Dr. Gould’s crispatus, but this doubt was dispelled on receipt of Mr. Haines’ specimens. It belongs to that group of which gratiosus, Phili., may be con- sidered the type. It certainly is nearest allied to crispatus, but may be distinguished by its being smaller, more transverse, having larger folds, and these thickly covering the whole disk, except on the last growth of old individuals ; also in being compressed over the middle, and emarginate at base and in the duplex form of the lateral teeth. The crispatus is disposed to be yellowish in the cavity of the beaks, while scobinatus is pearly white. In outline scobinatus approaches phaselus herein described, which is rather smaller, and is a polished shell with few folds. They both have the duplex 300 LEA’S DESCRIPTIONS OF EXOTIC GENERA lateral tooth in both valves. Like nwclews herein described the transverse close strize are very remarkable, and in both, the folds are beautifully developed on the inside In some specimens the strize are nearly obliterated.

Remarks.—Two opposed valves of nearly the same size were all which Mr. Haines received among his Siamese shells. In form and general character this species is nearly allied to U. imornatus herein described. It differs in being a little more transverse, and in being thicker and smaller. It resembles in outline U. c@ruleus, (nobis,) but has no bluish tint in the epidermis, and is entirely without rays, and is smaller. It is a very small species, not larger than a middle sized U. parvus, Barnes. It might be mistaken fora young U.

Remarks.—This species was procured by Mr. HE. Verreaux while in South Africa, and given to me while in Paris, in 1853. Subsequently Mr. Haines submitted specimens to me from the same habitat. The anterior muscular cicatrices present an unusual character in the three, being remarkably distinct. The undulations of the beaks are beautifully distinct, numerous and regular, and are delicately arranged also on the posterior slope as well as over a large portion of the beaks. In outline and general! character it is allied to U. Batavus, Lam., and more particularly to that variety named U. Carynthiacus by Ziegler. In outline and general form Africanus approaches Verreawianus, herein described, but it differs entirely in size and in the surface, being smooth and polished, while Verreawianus belongs to the sulcate division, and is usually twice the size; they therefore cannot be confounded. It approaches also to U. Caffer, Krauss, but differs much from the figure given by him, (Sudafrik Moll., p- 18.) It much more resembles a specimen given to me by the late Prof. E.

Femarks.—I owe the possession of several specimens of this interesting species to Mr. Verreaux, naturalist, of Paris, whose researches for many years in South Africa, &c., has added so much to various branches of natural history. It belongs to that group which I have called swlcate, from the transverse furrows which exist in the substance of the exterior of the shell. It is not so sulcate as Scamnatus, Morelet, nor is it so much compressed. In outline and general form, it is nearly allied to U. confertus, (nobis,) but is not so ventricose as that species, nor is it so angular behind. It cannot be confounded with U. Caffer, Krauss, as that species is much smaller, more compressed, the form more elliptical, the teeth more tuberculose and the nacre purple. I dedicate the species to that persevering traveller, Mr. Edward Verreaux. Unio Saurtierrianus. Pl. 27, fig. 17.

Remarks.—Several specimens of this shell are before me. Two of them are odd, young valves. The specimen figured has been in my possession some years, but being very closely allied to U. gratiosus, Phili., I feared it might prove a variety only of that species. The young specimens and other adults since received, satisfy me that they are distinct. The specimens of gratiosus which I have in my cabinent are much less transverse and much smaller. They are precisely the same in outline and folds with Dr. Philippi’s figure, (Conchylien, v. 1, t. 1, f. 5.) The Shurilefianus is more cylindrical and the basal margin is disposed to be emarginate. The folds are beautifully disposed over the upper part of the disk up to the tip of the beaks. They are remarkably minute, and so divergent and re-entering, as to make zigzag lines. In outline and size the Shurtlefianus is very near to cceruleus, (nobis,) also from India, but it may easily be distinguished from that species by being devoid of that bluish color, by the posterior margin being less angular, by the beaks being more medial and the nacre being salmon colored. The teeth are also less lamellar and the folds more numerous. It differs from crispatus, Gould, in having coarser folds, in color of nacre, as well as in having the teeth more lamellar, and the posterior margin being less acute. I have dedicated this species to Dr. Shurtieff, to whose kindness I owe specimens of several ages. Unio nrruterns. PI. 28, fig. 18.

Remarks.—A single specimen of this species only was submitted to me by Dr. Budd, but it differs so much from any described shell I am acquainted with that I have not hesitated to giveit a name. In general aspect it resembles U. ellipticus, (Diplodon ellipticum, Spix), but it is not transverse, seems to be without folds and has more marked transverse strie; the lateral teeth are more curved and the epidermis is more highly polished. The beaks of the specimen above described are eroded, and more perfect ones may be found to have undulations at the tips. Unto Suurrieworran. Pl. 28, fig. 19.

Remarks.—But a single specimen of this shell is before me; interesting from the fact, as an Australian species, it should so closely resemble an American one, as, at first sight, it might be considered to be merely a variety. It has very nearly the exact outline of Hopetonensis, (nobis,) from Georgia, and is nearly of the same color in the epidermis. It differs in having transverse furrows nearly over the whole disk, which in the Georgian are but slightly developed. It has smaller teeth, and in the left valve the cardinal tooth is single, in the right scarcely bifid. The color of the nacre of the specimen before me is of a darker purple than any of the Georgian species which I have seen. ‘The color of the nacre may differ in other specimens, as it does in the Hopetonensis, which is sometimes white and sometimes slightly salmon colored. The beaks of the specimen of Shuttleworthw before me are eroded, and therefore it is impossible to say if they be undulate; but I suspect that in perfect specimens they will be found to be so, as on the posterior slope very indistinct undulations may be perceived, decussating an obscure furrow running from the beaks to the posterior margin. If in other specimens these folds are found more numerous and more pro- nounced, then we ought to remove the species from the furrowed to the plicate group. The carina is so much elevated that it might almost be considered to belong to the alate division. Unio Dunxertanus. Pl. 28, fig. 20.

Remarks.—I1 owe the possession of this beautiful species to my friend Prof. Dtinker, of Cassel, to whom I dedicate it. Subsequently I procured a specimen from Mr. Verreaux, of Paris. When Prof. Diinker presented me with the specimen, he was under the impression that it was D’Orbigny’s rhuocoica, but that is quite a distinct species, being less transverse, of a lighter brown and with smaller and shorter coste at the beaks. The costee of Diinkerianus extend, in the two specimens before me, somuch longer over the disk, and particularly near the umbonial slope, that it must be entitled to be placed among the folded species.

Remarks.—This species is very remarkable for its diminutive size. There were only two specimens submitted to me by Mr. Haines, and I believe they are all he received. They are nearly of the same size ; and if they be of normal dimensions, the species is certainly the smallest I am acquainted with. It is nearest to U. crispatus, Gould, in general appearance, being covered over with nearly the same kind of folds, which are green like crispatus. In outline, however, it differs very much as well as in size, not being more than one-third the breadth. The umbonial slope is also much more angular. It might be suspected that it had been mistaken for a young crispatus, but on comparison with a young crispatus before me, I find it flatter, less robust, with smaller folds and more yellow. The minute strie over the disk are close and lamellate, and are of a brownish color. The folds over the whole disk are strongly marked, are green and disposed to run into angles, while the intermediate spaces are yellowish. On the inside the folds are distinctly visible. Unio Brownu.

Remarks.—The specimen above described is probably quite a young one, and I have great doubt of its really being a native of Arabia. Among many fine shells brought by Captain Brown, from nearly all parts of the world where he carried on his commercial affairs, were many rare and fine specimens from the rivers of South America. This specimen was marked in one valve “ Mocha ;” in the other, “ Red Sea ;” brought there by trading vessels from South America, having some of the characters so that he most probably purchased it in Arabia; and still it may have been of that habitat, particularly the diverging costz on the beaks; which character so peculiarly belongs to most of the species of that quarter of the globe. It seems to be more nearly allied to U. Paranensis, (nobis,) than to any species Iam acquainted with, but it is not so rotund, nor is it so much inflated along the umbonial slope. The coste of the beaks are smaller, and the epidermis is green and not brown as in Paranensis. It is also somewhat like U. Burroughianus, (nobis,) from South America, but is not so transverse as that species, and is not so high on the umbonial slope. On the posterior slope there are two distinct rays from the beak to the margin, one being yellow and the other dark green. 1 name this in honor of the late Captain Brown, of Beverly, Mass., to whose kindness I owe the possession of the specimen.

Remarks.—A. young shell, apparently not one-fourth grown, was sent tome some time since by Mr. C. M. Wheatley, who procured it from the Rio Negro, at the distance of 1200 miles from the mouth of the Amazon. After comparing this young individual carefully with all my South American specimens, and with the descriptions of Spix and Von Martius, as well as those of D’Orbigny, I am satisfied that it can only be as- similated to a specimen which that distinguished traveller and zoologist, Mr. D’Orbigny, sent to me with several other specimens as U. lacteolus, (nobis,) (delodontus, Lam.) I have always doubted that specimen being the same species with those which it' accom- panied, and now connect it with this young specimen under the name of my friend Mr. Wheatley. Iam not prepared to say, when we shall find mature specimens from the Rio Negro, that it may not prove distinct from the shell from Monte Video. The form of the former is more triangular, and it varies in being flesh colored. The species above described may be distinguished from delodontus, Lam., by being less transverse, and having longer and larger diverging ribs at the beaks, which in both specimens before me converge a short distance below the tip of the beak so as to form re-entering angles. It differs from Burroughianus, (nobis,) and Paranensis, (nobis,) in being less transverse than the former, and being less rotund than the latter. It is also less rotund than membranaceus, Maton.

Remarks—Among a number of interesting land and fresh water shells which I procured from Mr. E. Verreaux, in Paris, was a single small specimen of this species, evidently quite young. I should suppose about one-fourth grown. ‘The above diagnosis therefore may be found to be, in many respects incorrect, when mature individuals shall be examined. ‘The oblong outline of this shell is remarkably regular. The costz of the beaks are smaller on the posterior and anterior slopes and several of them form re-entering angles on the posterior slope and on thesides. This species has some affinity to Charruanus, D’Orb., but differs in being more oblong, in having smaller costee on the beaks, and in having the posterior slope more elevated. Unio Nurranuianus.

Remarks.—I owe to the kindness of Prof. Nuttall, two specimens of this pretty little species, which he gave me on my last visit to England, in 1853. In outline it approaches U. olivaceus, (nobis,) from Calcutta, but is a little more angular on the posterior margin. It is by no means so thin in the substance of the shell, and differs in the teeth, they being in the Nuttal/ianus thicker and less lamellar. The color is very different, the olwaceus being pale blue, while both the specimens before me of ‘Nuttallianus are salmon colored within and olive without, and with transverse bands. There is a group of Uniones in India, which are disposed to be bluish, and the ceruleus, (nobis,) may be considered decidedly the type. The Nuttallianus has an epidermis of rather a bluish green olive, and the nacreous matter deposited in the interior of the beaks of both specimens is decidedly blue. The tips of the beaks being eroded in both specimens, it is impossible to say if there be undulations, but the blue hue of the nacre in the beaks is very observable there. The outline of U. Keraudreni, Hydoux, is nearly the same with this species; but they are evidently distinct. I dedicate this pretty little species to my old friend Prof. Nuttall, who has done so much to elucidate the natural history and botany of the United States. Unto umsBrosus. PI. 30, fig. 26.

Remarks.—W hen I described Unio Tampicoensis, m 1835, (Trans. Am. Phil. Soc. Vol. 6, p. 24,) I was in possession of the above described shell also by the kindness of the late Dr. Burrough. In the remarks, I then mentioned that in the younger specimens the epidermis was of a yellow brown, and that indistinct rays might be observed. Having had access to other specimens all of the same size, and particularly a fine one from Mr. Anthony, of Cincinnati, who also obtained it from Dr. Burrough’s collection, I am satisfied that, although nearly allied to Yampicoensis, it must be considered to be distinct. It differs in being not quite so oblique, in the beaks not being so prominent, the epidermis not being blackish but of a fine dark brown. It also has obsolete rays, while the other seems to have none, and the nacre is disposed to be more rose color and purple. All the specimens before me are more or less thus colored, while Zampicoensis, is usually white with pinkish lateral teeth. There is rather a remarkable feature in the three specimens before me, about the centre of the cavity of the interior of the disk, all of which are granulose with small irregular pearls.

Remarks.—Among the Uniones of Lake Nicaragua, this species, taken by Dr. New- comb, has not, I believe, heretofore been observed. It is a very remarkable species, as well from its outline, as from its singular corrugate and furrowed disk. It differs from all the species which I know, in this character. We have some species of Naiades with wrinkled epidermis,* but not so much so as this, nor are they accompanied by furrows like this. It differs from U. aratus, (nobis,) also from Lake Nicaragua, in being round and in having wrinkles as well as furrows. ‘T'wo of the three specimens before me are adult, and in these there is apparently, in the left valve, a disposition to form a third division of tooth. The largest of the three specimens is probably a female, as there is an enlargement at the posterior basal margin, which indicates that sex. It causes the outline to present a subtriangular form, which is not the case with the other two. T owe to Dr. Newcomb the possession of this beautiful little species, as well as many other fresh water and land shells, and with pleasure dedicate it to him, who has proved so industrious and successful an investigator in this branch of Zoology.

It has that character of the cardinal teeth, being single and double on the reversed sides, so common with the species from the East of Asia. The tips of the beaks being eroded, the character of the undulations cannot be given, but it is evident from those which may be yet seen on the posterior slope of this specimen, that they must be numerous, regular and close. In outline and in color it is near to U. crocatus, (nobis,) from Georgia ; but is a much smaller species and rather more transverse. Unio Cotorapornsis. PI. 31, fig. 29.

It is nearly allied to purpuratus, Lam., on one side, and to alatus, Say, on the other; it is less inflated Or AND SPECIES OF THE FAMILY UNIONIDA, 31 than the first, and more inflated than the latter, and the posterior slope is nearly raised into a wing. It is not obovate like purpuratus. Young and perfect specimens will probably be found to be quite alate. The purple color of the specimen before me is not quite so dark as the alatus and purpuratus. In my specimen there is in each valve an imperfect cicatrix, situated nearly in the centre of the interior of the disk, and such may be the case with Dr. Budd’s. If this should be found to be developed in the species, it will resemble in this character the trapezoides, (nobis,) the only Unio I know to possess the additional muscle (ventral muscle). The beaks of the specimen before me are too much eroded to give the character of the tips, but they are evidently slightly undulate. It differs from Yampicoensis, (nobis,) to which it is allied, by being a larger species, being higher in the carina of the posterior slope, in having a brown radiated epidermis instead of a blackish rayless one, and in the purple color of the nacre.

Remarks.—I owe to the kindness of Professor Poey the possession of two specimens of this interesting species, and I dedicate it to him. In its outline it is nearly like 316 LEA’S DECRIPTIONS OF EXOTIC GENERA that of Unio cylindricus, Say, but it is a much thinner shell and entirely without tubercles, which are so remarkable on the umbonial slope of that species. It is closely allied to U. Fopew, (nobis,) but is not so much compressed, is different in color, more cyclindrical as well being furnished with granules. The epidermis of Poeyanusis very remarkable. It is very thin and firmly attached to the calcareous matter, and when examined witha good lens very minute granules may be seen over the surface ; at the anterior part the strie are imbricate. The two specimens differ in color. The younger, being half grown, is of a straw yellow, while the older one is an olive yellow to that point of growth, and straw yellow beyond that to the margin. The younger is entirely without rays, while the older has obsolete rays on the posterior portion. AnopontaA Hortonis. Pl. 52, fig 31.

Remarks.—This species, of which I have but a single specimen before me, was brought by the Rey. Mr. Holton from the upper Cauca, interior of New Granada, where they are found in abundance, in “a pond, like the Illinois Prairie Ponds, an acre in extent, with muddy shores, being 6 to 15 feet deep in the centre, without inlet or outlet, and not surrounded by marshy ground, the distance from the Cauca River being 5 miles. This pond is within half a mile of Cartago.” AND SPECIES OF THE FAMILY UNIONIDA. of The above described species is more like Anodon radiatus, Spix, (Test. Fluv. Bras. pl. 23, fig. 1,) than any other South American species. It is about the same size, but in outline it differs by being more oblong and less elliptical. It differs also in not being rayed. It is very nearly of the same outline with Anodonta fluviatilis of our rivers, but it cannot be confounded with that species, as it has the peculiarly formed fosset at the posterior end of the ligament, which is so remarkable in the South ‘American Anodontg. The singular crimpled rays in the epidermis are very remarkable, but it may not be a permanent character of the species. It is to be regretted that a single specimen only has come under my view. I owe this one to the kindness of the Rey. Mr. Holton, who mentions in his travels that they were in abundance near Cartago, and to him I dedicate it. Family NALADES. Subgenus PLAGIODON.* Testa zquivalvis, inzequilatera, obliqué trigona, valdé inflata ; dentibus cardinalibus crenulatis, compressis, transversis, curtis, in utroqué valvulo duplicibus; dentibus lateralibus nullius; ligamentum vix ex- trorsum ; impressio. muscularis anticé composita. Proc. Acad. Nat. Sci. Vol. 8, p. 79. Shell equivalve, inequilateral, obliquely trigonal, very much inflated; cardinal teeth crenulate, compressed, transverse, short, double in each valve ; no lateral teeth ; muscular impression composite before. This subgenus is proposed for a fluviatile shell, which is nearer to Monocondylea, DOrbigny, than to Margaritana, Schumacher, and may be considered properly, as so interposed as a link to connect them. It has the epidermis of Monocondylea, being of a dull cloth-like texture, and not polished and smooth, like the Unio generally is. The point in which it chiefly differs is the peculiar structure of the teeth. As in Monocondylea there is no lateral tooth, the part of the dorsal margin where that exists in the Unio forming a plate, is here simply a line, forming a margin over a deep cavity, on which line is placed a thin delicate ligament. The cardinal tooth is large, but unlike the Margaritana it is transversely compressed, and the upper division is longer and begins immediately over the lower one, between it and the beak. In Monocondyleca the cardinal teeth consist of one smooth rather large lobe or callus, in each valve, passing each other, and fitting into a corresponding depression in the opposed valve. If we may judge from a single specimen of Playiodon I should conclude that the substance of the valves was never so thick as that of Monocondylea. It is much more inflated, the three diameters being nearly the same, that through the axis being rather smaller. Being a very light shell, and having so peculiar a form, it cannot be very locomotive. From its rotundity, and having the beaks nearly * maaypios, transversus and édsc, dens. $1 318 LEA’S DESCRIPTIONS OF EXOTIC GENERA terminal, incurved and recurved, it at once reminds one of Jsocardia cor, Lam., or rather of Jsocardia Moltkiana, Lam., having a notable angle on the umbonial slope and presenting a perfectly cordate form on the anterior view. The posterior cicatrices are confluent like Monocondyleea, and but slightly impressed. ‘The inferior anterior cicatrices are deeply impressed, and so closely united as scarcely to be distinguishable. The superior anterior cicatrix is placed on the inner side of the cardinal tooth, and higher up than on that of the Monocondylea. The dorsal cicatrices are placed so far into the deep cavity of beaks, as to be but partly and faintly visible. The absence of the soft parts of this shell is greatly to be regretted. From the clobular form, the epidermis and the teeth, we would be led to expect to find some- thing different in the structure of some of its organs, as it is very likely to be in its habits, from Monocondylea or Unio. Judging from avery imperfect left valve of Monocondylea Guarayana, D’Orb., all that I have seen, I should not be surprised if it would prove to belong properly to this genus. Certainly the form of tooth is different from that of the other Monocondylea. It is, however, very much compressed, and is much thicker in the substance of the shell. / The epidermis of Plagiodon is of that texture and color, which reminds one of some of the estuary genera, Cyrena, Clathrodon, &., but its pearly nacre and form of teeth place it among the Naiades without doubt.

Remarks.—I procured this very remarkable shell in Paris, from Mr, HE. Verreaux, whose researches and collections in South America, Africa, &c., have been so extensive. It has the general aspect of a very much inflated Monocondylea Paraguayana, D’Orb., but the form of the teeth is totally different, and the shell thinner and more vesicular. The anterior slope is almost as cordate as kocardia Moltkiana, Lam., the beaks presenting an incurved form somewhat like that shell. The angle on the umbonial slope is also somewhat similar and it has a like flattened side. The anterior lanule is very wide, and immediately under the point of the beaks there are three transverse impressed lines, very unusual in the Naiades, which may not be constant even in this species.

Remarks.—This very remarkable species of the TZriquetra, of Klein, (Hyria, of Lamarck,) was first placed in my hand by Tho. R. Ingalls, M. D., to whose kindness I am indebted for many new species from rare and distant habitats. This specimen consists only of the right valve, and was among shells received by Mr. Asa Fitch, of Salem, New York, in a box from China, with Anodonta magnifica, Dipsas plicatus, and other well known Chinese species. This is certainly the most remarkable form of any of the genus TJriquetra yet observed. Its remarkable transverseness at once removes it from subviridis, Klein, (avicularis, Lam.) In outline it approaches Spatha celestis, (nobis.) It is the first time that this genus has been observed out’ of South America, where it has heretofore been considered to be peculiar. The great posterior cicatrix is of an unusual form, being irregularly elongate and but slightly oblique to the tooth above it. The minor superior cicatrix is unusually distant from the posterior terminal point of the lateral tooth, where it is usually placed in all the family Naiades. In this shell itis removed quite half an inch from the point, and placed rather below the tooth itself and nearly perpendicular to the end of the great cicatrix, which here is obliquely directed towards the anterior instead of the posterior margin. The three anterior cicatrices are remarkably distinct, the superior one being placed on the end of the cardinal tooth. There is an appearance of a row of cicatrices under the dorsal line, anterior to the great cicatriz, which is situated anteriorly to the cardinal tooth. The whole interior of the valve is covered with beautiful minute papille. The beak is so much eroded that it is impossible to say if the tips in a perfect state be undu- late or not. In the short diagnosis which I made of this new species of Triquetra, (Proceedings, vol. vill. p. 79,) I had but a single valve, which had the appearance of being twisted like Arca tortuosa, Lin. This extraordinary form, which had never been suspected to exist in any member of the family Naiades, excited great interest with the Zoologists who saw it; but it was still a matter of doubt whether the curve, although exceedingly regular and presenting no appearance of constraint or injury, might not be abnormal, This doubt has now, however, been put entirely at rest, for the curve AND SPECIES OF THE FAMILY UNIONIDA. 321 of the two specimens now before me, are so precisely the same, that when the odd right valve is placed against the left of the other, they fit perfectly, proving that the curve is a mathematical law belonging to the species. The specimen now figured belongs to H. Cuming, Esq., of London, and is nearly perfect. My single valve was recognized by Mr. Cuming at once, on his recent visit to this country, to be the same as that in his cabinet, and he promptly and liberally offered to place this unique specimen in my hands, for a more perfect description and figure than could be given of the single immature valve I already had. Mr. Cuming’s specimen is nearly six inches along the dorsal line to the angle of the posterior margin, and this line deflects quite two inches in the course of the six inches from a straight line, and it is so twisted that the basal margin at the posterior end turns up to be on a plane with the dorsal line at the beaks. ‘This remarkable curve causes the long lateral teeth to have a curve of double curvature. The greatest distance from the dorsal to the basal margin is one inch and three-tenths. The greatest diameter is nine-tenths of an inch, which gives it a sub-cylindrical form, and it is not unlike a twisted banana, (Musa sapientum.) This perfect specimen presents the superior portion of the valves covered with small, regular tubercles, which was not suspected in the original, somewhat imperfect single valve, there being on it only a few irregular undulate markings. Mr. Cuming’s specimen settles the doubt as to habitat. He received his from Shanghai, and therefore Mr. Fitch and Dr. Ingalls, to whom I owe the possession of the single valve, were right in assigning it to China. Doubts arose of this from the fact that, heretofore, Zriquetra has been considered to be confined to South America. I propose the name should be changed from that I originally gave it, (7. lanceolata,) as inappropriate to the complete mature shell, to that of contorta, which is very descriptive, and can never be mistaken. . itv Bc? ite. ae yf Oe ti (5% i iat 5 nus FS oH A. ie ore SAU Ta ks a enue sho ea we SU AR aul Cue Ta ifohuty diab eae ) (ue, Sen ae Oe Le UH OF ae ; et Tht ay aby che 5 tm * ’ f a ‘ ‘ sive 7, . ‘ + ty be ) , # ’ ea f pf a ft ' 5 T AS ‘ ‘ .

XX.— Observations on a yroup of Cretaceous Fossil Shells, found in Vippah County, Miss., with descriptions of fifty-six new species. By T. A. Conran. The Cretaceous strata of Mississippi have long since been observed and partially noticed by geologists, and the lamented Professor Tuomey has described a number of their fossil contents. I now introduce quite a distinct group of shells, which are imbedded in a different matrix compared with the prevalent cretaceous marls, green sand and limestones. The discovery of these beautiful organic remains is due to the indefatigable exertions of Dr. W. Spillman, of Columbus, who has forwarded a collection of specimens more or less perfect, consisting of nearly sixty species, all of which appear to be unpublished except Scaphites Conradi. The appearance of these shells is like that of eocene species which have merely lost their animal matter, and in this respect are very unlike the condition of similar genera in the contiguous rocks of the same era. The fossils are imbedded in a sandy marl of a dark gray color, the principal constituents of which are fine scales of mica and grains of quartz mixed with fragments of small shells; and though some of the very thin species are distorted, the stronger retain their original shapes and are generally very perfect. Species of CRASSATELLA, NucuLA and Muretrix have the valves united as in life, as well as a few of the extremely thin InoczrAmt, though the latter have been more or less distorted by pressure. The numerical proportion of species of Cephala and Acephala is nearly equal. The external sculpture of all is as sharply defined as in existing species. Besides ScApHitEs and Bacutirss, there is only one shell in the collection which resembles a species of the green sand or limestone, and itis quite distinct. The rare genus Putyintrss is herein for the first time introduced as an American form. The analogous species, as well as that of GERVILLIA, occurs in the Baculite limestone of France and Normandy, which I believe is referred by D’Orbigny to his Senonien Stage, the same in which he includes the Cretaceous fossils of North America. It is interesting to find bivalves of so remote an era in sufficient preservation to exhibit generic characters as clearly defined as they are in living shells. In this condition are the hinges of Grrvyinn1a, Putyinites, Crenomes and Carpium. ‘There are also specimens of BacuLites and Scapuites which exhibit the interior divested of all extraneous matter, and delight the eye with exquisite curves of the foliated septa, whilst the shells glow with brilliant iridescent tints. 524 CONRAD’S DESCRIPTIONS OF This beautiful series of cretaceous forms seems to be very limited in geographical distribution, so far as our present knowledge extends. It is probably unknown as yet beyond the limits of Tippah County, which borders on Tennessee. No account has been given of such a group by the State Geologists of Tennessee or Alabama. Dr. Spillman informs me, “ The fossils you have now under examination were found in the bluffs of Owl creek, three miles north of the town of Ripley,” and he concurs in opinion with me that they might properly be named the “ Ripley group.” He also remarks that Ammonites placenta occurs in it with the shell preserved, and that in connection with the Ripley group, or in the same locality, are “ Hxogyra costata, *Gryphea mutabilis, Ostrea plumosa, Natica petrosa, Nautilus Dekayi, dc., with the shell more or less preserved, in/an argillo-caleareous marl,” but none of these species are contained in his collection sent me from Tippah County. Professor Harper, in his report for 1857, describes some of the Teenies of the above group near Ripley, and names many of the genera of its contained fossils. It would perhaps be convenient to designate these strata Upper Cretaceous, in contradistinction to the limestones and marls beneath, which are palzeontologically so distinct. ACHPHALA.

Suboval, very thin and fragile, ventricose ; radii angular, promi- nent, about 30 in number, towards the extremities minutely tuberculated ; ribs obso- lete near the buccal end; basal margin somewhat salient opposite the umbo; trun- cated posteriorly ; anal end truncated, nearly direct. This species is proportionally shorter than the elegantulwm or protextwm. The largest specimen in Dr. Spillman’s collection is not so large as those species usually are. Received since the plates were finished. There are two other species of this genus in the inferior Cretaceous marls. Papyridea (Cardiwm) elegantulum, Roemer, and P. (Cardiwm) proteatum, Con. CARDIUM, Lin. 1. Carprum tippanum. PI. 34, fig. 8 6. Cordate, profoundly ventricose, rather thick ; umbo and summit prominent; ribs flattened, little prominent, tricarinate, armed with - prominent erect spines; in the intercostal space is a row of minute tubercles, except on the posterior side, where a prominent intercostal line appears. A mere fragment, so well marked, however, that the description and figure will characterize the species. 7 2. CARDIUM RIPLEYENSE. A small cordate species, with minute equal radii, between each of which is a series of comparatively long hair-like spines. Subgenus LAXVICARDIUM, Swainson. 3. Carprum SprLiMANI. Pl. 34, fig.3. Oblong or profoundly elevated, inequilateral, profoundly ventricose ; umbo and summit elevated; beaks nearly contiguous; surface with distant irregular grooves on the anterior side, and 3 to 5 radiating slightly impressed furrows on the umbonal slope. Length 2g inch. Height 42 inch. A large and remarkably elevated species with a very thick hinge and profound teeth. The surface is smooth and only ribbed about the umbonal slope, and on the posterior side of the umbo where in one specimen are about 18 radii; those behind — the umbonal slope fine and indistinct without the aid ofa glass. Named in honor of Dr. W. Spillman. NEW CRETACEOUS FOSSILS. [Se) bo —{ OPIS, Defrance. 1. Opts BicARINATA. A small orbiculato-trapezoidal, ventricose species, smooth ; umbonal slope and posterior submargin carinated, postal area concave. 2. OPIS BELLA. ‘Triangular, convex, polished, with regular and elegant concentric lines, or minute flat ribs, separated by linear grooves; posterior side cuneiform. About the size of the following species of Tellina, but a little longer and more pointed posteriorly. TELLINA. TELLINA RIPLEYANA. Ovato-triangular, equilateral, compressed, polished ; concen- trically lineated towards anterior extremity. Length nearly 4 inch; height nearly $ inch. This and the two preceding species of Opis were discovered after the plates were finished. They will be figured in a future number of this Journal. CRASSATELLA, Lam. CRASATELLA RIPLEYANA. Pl. 35, fig. 3. Triangular, very inequilateral, thick, flexuous or plicate posteriorly ; umbonal slope angulated, subcarinated ; disk covered with numerous irregular concentric furrows or coarse prominent lines; posterior side cuneiform, extremity obtusely rounded ; margin above obliquely truncated; posterior margin opposite the umbo angulated; inferiorly concave; margin densely crenu- lated within. This, from the number of specimens sent, I judge to be an abundant species, very distinct from all others of this country which have hitherto been described. The cardinal plate is very broad, and the teeth thick and prominent. Its state of preservation is equal to that of any Tertiary bivalve. NUCULA, Lam. NUCULA PERCRASSA. PI. 35, fig.4. Triangular, very thick, ventricose, inequila- teral, densely radiated with minute impressed lines; anterior end subnasute, margin obliquely truncated; posterior side cuneiform, extremity slightly salient, rounded, situated much above the line of the base; basal margin rounded, sometimes slightly contracted anteriorly; within crenulated on the margin; submargin thickened ; cicatrices deeply impressed ; cardinal teeth thick, fosset oblique. This species appears to be abundant and in excellent preservation; one specimen has the valves united. The interior is silvery; the pallial impression very distinct, and. an irregular line of five small cicatrices runs over the upper part of the valves in the direction of the shell’s length. The form of this NucuLAis very unlike any other American species. 328 CONRAD’S DESCRIPTIONS OF CIBOTA, Browne.—BYSSOARCA, Swainson. CrsorA LINTEA. PI. 34, fig. 11. Rhomboidal, very inequilateral ; sides flattened or slightly contracted, radii minute, close, reticulated, except on anal side, where the radii are wider and smooth; hinge and basal margins parallel, the latter slightly contracted; anal margin very obliquely truncated. This genus has been named NaAvicuta by Blainville, and Byssoarca by Swainson. CUCULLAA, Lam. CUCULLHA CAPAX. PI. 35, fig. 2. Obliquely triangular, inequilateral, profoundly capacious, elevated ; posterior slope flattened, very broad, forming nearly a right angle with the terminal umbonal slope which is abruptly rounded ; valves slightly contracted ; umbo profoundly prominent, beaks distant; surface reticulated with fine lines, the radii in pairs, most conspicuous posteriorly, largest on the left valve. 2. CucULLHA TIPPANA. PI. 35 fig. 1. Short trapezoidal, inequivalved, inequila- teral, ventricose ; radiating lines numerous, reticulated, most conspicuous on the left valve; umbo prominent; beaks rather distant; cardinal area profound, with three angular impressed lines; umbonal slope acutely rounded. In the specimen figured, the margin of the larger valve is thick, abruptly grooved within, in which groove the margin of the opposite valve is inserted. Allied to C. Shumardi, Meek. DREISSENA, Van Beneden. DREISSENA TIPPANA. PI. 34, fig. 14. Falcate, with distinct lines of growth; front excavated, the margin acutely angular; the dorsal and posterior margin form a regular curve ; base rounded ; beaks acute. This shell somwhat resembles Dreissena polymorpha. The hinge is not accessible in the only specimen in the collection. The valves are united and are remarkably perfect. The form is not unlike that of Mytilus falcatus, D’Orbigny. PINNA, Lin. PINNA LAQUEATA. A fragment—ventricose, with eleven prominent, slender ribs} interstices concave. GERVILLIA, Defrance. GERVILLIA ENSIFoRMIS. PI. 34, fig. 10. Ensiform or falcate, profoundly compressed, iridescent ; hinge with about twenty-seven radiating prominent teeth; cavity very shallow, with an irregular surface, the upper margin angular; within pearly and iridescent. Two valves of this species are in Dr. Spillman’s collection, which are both broken NEW CRETACEOUS FOSSILS. 329 off as represented in the figures, but the remainder perfectly preserved, and the hinge is as entire as that of a recent bivalve. It differs from G. solenoides, in having an anterior wing with a truncated margin; in being much more compressed, and in having an uninterrupted series of prominent cardinal teeth, &c. CTENOIDES, Klein.—LIMA, Brug. CTENOIDES ACUTILINEATA. PI. 34, fig. 2. Oblong, oblique, very thin ; posterior side radiated with acute, prominent lines, thirteen to fifteen in number; anterior side with minute, close, radiating lines ; surface concentrically wrinkled ; posterior margin sub- rectilinear. This somewhat resembles L. Wacoensis, Roemer, in outline, but it is less ventricose, and has radiating lines, whilst the other is costate. Klein founded this genus on the shell known as Lima glacialis, and the L. scabra is the type of his genus Raputa. INOCERAMUS, Parkinson. 1. INOcCERAMUS ARGENTEUS. PI. 34, fig. 16. Obliquely suboval, very thin, smooth, inflated anteriorly; umbo prominent; summit elevated ; lines of growth towards the posterior margin assume the form of squamose striz ; anterior side very short; mar- gin obtusely rounded. 2. INOCERAMUS COSTELLATUS. PI. 34, fig.12. Obliquely subovate, ventricose ; radii slightly prominent, rounded, close, disappearing posteriorly, obsolete towards the anterior margin; concentric acute lines ornament the surface; anterior side very short, obtuse; umbo and beak of larger valve very prominent. This species is marked exteriorly like a PHoLapomya, but is inequivalve, with the hinge of an InoczrAmus. ‘The specimen is distorted. Species of this genus were figured by Klein in 1770, under the generic names of SponpIoLitHos, Muscuites and PHoLADIS. OSTREA, Lin. OsTREA PECULIARIS. PI. 34, fig. 7. Oblong or elliptical, thin, ventricose along the middle and depressed on the sides; surface with radiating wrinkles ; margins towards the apex denticulated. A thin and abundant species remarkable by the tuberculated or denticulated mar- gins and elongated trilobe shape. 2. OSTREA CONFRAGOSA. PI. 34, fig. 4. Very irregular; rather thin ; lower valve profoundly ventricose, with deep irregular cavities or depressions. The lower valve only is known,.and is very unlike any other Cretaceous species in the United States. 84 330 CONRAD’S DESCRIPTIONS OF 4, OSTREA DENTICULIFERA. Pl. 34, figs. 1 and 8. Irregular, moderately thick, indented, but not plicated; upper valve flattened ; hinge area wide, with a transverse ridge at, the base of the fosset; lower valve moderately capacious ; upper margins denticulated ; muscular impressions large. EXOGYRA, Say. EXOGYRA INTERRUPTA, PI. 34, fig. 15. Adhering, thin ; lower valve with inter- rupted radiating costae; upper valve entire, with a thickened margin. A small species. The lower valves in all the specimens adhere to other shells and nearly conceal the exterior character. PULVINITKES, Defrance. PULVINITES ARGENTEA. PI. 34, fig. 5. Transversely subovate, compressed ; per- forated valve slightly concave; foramen oval, from its upper margin a channel extends to the apex; substance of shell silvery, thin; cardinal plate broad, with about thirteen radii or teeth ; the lower valve presents within the appearance of two muscular impressions, the one above the other, the former striated. The present species of this rare genus is allied to P. Adansonw, but differs from the figures of that species in having a broader hinge plate, and much less curvature of the posterior margin. It closely resembles an AnomiA exteriorly. P. Adansonii characterises the Upper Cretaceous rocks of Hurope. ANOMIA, Lin. ANOMIA SELL&ForMIS. Pl. 34, fig. 6. Suborbicular, with a short fold anteriorly towards the hinge line; posterior side with a profound plication. Length # inch. There is but one valve of this species in Dr. Spillman’s collection, and _per- haps other specimens may exhibit a considerable variation from the saddle-shape character. GASTEROPODA. STROMBUS, Lin. Srrompus DENsATUS. PI. 35, fig. 14. Lip expanded, very thick; coste disap- pearing on the middle of the volution; labrum suddenly thickened, with a groove behind the raised margin; a calcareous deposit sometimes coats the whole shell, rising into an oblique, thick, prominent ridge, the upper margin of which is on a line with the apex. APORRHAIS, Petiver. APORRHAIS DECEMLIRATA. PI. 30, fig. 11.

The beak is broken as well as the rostrum of the outer lip, but otherwise the only specimen in the collection is very well preserved. HARPAGO, Klein.—PTEROCERA, Lam. HARPAGO TIPPANUS. PI. 35, fig. 25. A fragment, with smooth subangulated volu- tions, a carinated line revolving at the base of each; rostrum of the labrum pro- foundly extended, trilobate, the central and upper lobe profoundly carinated in the middle; substance of the shell thin. The labrum has evidently been extended above the apex, but only a slight trace of it remains near the upper part of the spire. The specimen is evidently a young or immature shell. RIMELLA ? Agass. RIMELLA CURVILIRATUS. PI. 35, fig. 9. Fusiform, ribbed longitudinally; ribs somewhat curved, slightly sinuous, about twenty-three in number on the body volu- tion; interstices transversely striated ; beak produced ? CONUS, Lin. Conus CANALIS. PI. 35, fig. 22. Spire prominent, volutions profoundly angular in consequence of a deep channel revolving at the suture. A very remarkable species, in its profoundly channelled suture presenting a strong contrast to more modern fossil or recent cones. DRILLIA, Gray. 1. Driniia NovemcostaTA. PI. 35, fig. 13. Subfusiform, spire elevated ; volutions scalariform, having distant, wide, prominent, rounded slightly oblique costa, termi- nating above at a crenulated line which borders the suture ; body volution with short, _ very prominent, tuberculiform, thick ribs; revolving lines obsolete above, prominent and alternated inferiorly. 2. DrILuiA? TIPPANA. PI. 36, fig. 5. Subfusiform, with thick, rounded, smooth, longitudinal ribs on the body volution, each tuberculiform at the summit; ribs of the spire tuberculiform at base, or interrupted in the middle; base with thick, prominent revolving lines.

Elongated, slender; spire subequal in length to body volution and beak; volutions ribbed longitudinally; ribs slight and somewhat curved above, where they are interrupted by a deep revolving furrow, which causes the appearance of a prominent line bordering the suture ; surface of shell with revolving lines distinct on the body whorl and beak. FUSUS, Klein. FUSUS NOVEMLIRATUS. PI. 35, fig. 18. Elongated ; spire elevated, acute; volutions seven ; longitudinally costate and transversely striated, ribs thick, prominent, rounded ; suture margined by crenulated line; body volutions having about nine distant, very large rounded costz which become obsolete about the middle of the volution ; inferiorly marked with longitudinal lines or furrows ; beak slender, elongated, sinuous. Subgenus AFER. FUSUS BELLALIRATUS. PI. 30, fig. 17. Fusiform, spire prominent, acute; volutions of spire seven, subscalariform ; tuberculated inferiorly and ornamented with revolving lines ; body volution ribbed longitudinally, and having prominent transverse, robust lines, which on the ribs assume a tubercular aspect ; beak elongated. This shell is referred to a subgeneric division of which Fusus afer, Lam., may be regarded as the type. PYRIFUSUS, Conrad. Pyriform ; columella broad, thick, flattened; body volution transversely oval. PYRIFUSUS SUBDENSATUS. PI1.35, fig. 12. Subpyriform ; spire short, subscalariform, volutions four ? longitudinally ribbed and spirally lineated, lines minute ; body whorl wide, contracted above where there are longitudinal wrinkles and revolving lines ; below are prominent ribs becoming obsolete about the middle, and prominent, revolving lines over the whole surface below the shoulder. FICUS, lew. Ficus octotrratus. Pl. 35, fig. 6. Pyriform; spire conical ; costae of body volution about eight in number, inclined to be square, distant; beak long and slender. RAPA, Klein. RAPA SUPRAPLICATA. PI. 35, fig.20. Pyriform ; spire depressed, volutions flattened above ; summits ornamented with oblique, curved strie or grooves. A very much broken specimen, but the fragment exhibits marked characters. It is a very ventricose, smooth species, easily recognised by its flattened volutions and curved lines. + aie al Dn vo (SU) (a NEW CRETACEOUS FOSSILS. VOLUTILITHES, Swainson. VOLUTILITHES CRETACEA.

Length of fragment 23 inches. } Another less perfect specimen has been a much larger shell. This species bears some resemblance to Voluta Lamberti, of the British Miocene. A young specimen which is figured in outline has a very acute spire and minute revolving lines. The columella being imperfect, the plaits have not been observed. The base is narrow, produced and but slightly emarginate. CHEMNITZIA, D’ Orbigny. 1. CHEMNITZIA INTERRUPTA. PI. 35, fig. 15. Spire prominent, scalariform, pro- foundly costate longitudinally ; ribs interrupted below the suture by a deep furrow; base with rather distant, revolving lines. Columella and base imperfect; therefore this and the following shell are only pro- visionally referred to CHEMNITZIA. : 2. CHEMNITZIA DISTANS. PI. 35, fig. 30. Short—subfusiform; spire prominent, subscalariform ; volutions four, reticulated ; body volution with longitudinal, distant ribs intersected by distant, prominent, revolving lines; columella profoundly curved near the middle.

Acutely subovate ; volutions five ; spire subscalariform ; body whorl ventricose ; longitudinal ribs narrow, prominent, distant ; revolving lines prominent, distant, with an occasional minute intermediate line; columella profoundly incurved ; labium reflected ; base subumbilicated; shoulder of body volution with minute revolving lines, and one larger than the others. TURRITELLA, Lam. 1. TURRITELLA TIPPANA. Pl. 35, fig. 19. Subulate . sides straight; volutions carinated with revolving lines, two on each volution larger than the others, remote, one nearly equal in size, nearly medial, and three other fine lines; whorls of spire slightly cari-_ nated at base. 2. 'TURRITELLA ALTILIS. Broad at the base, rapidly narrowing, apex very acute ; volutions about eighteen, sides straight, coste four, in pairs, two upper pair more approximate, and smaller than the inferior pair; three on the lower part of body volution ; shell marked with minute revolving lines, the central one between the costz largest. i Length 3 inches; width of body volution 1 inch. 86 334 CONRAD’S DESCRIPTIONS OF NATICA, Lam. Subgenus LUNATIA, Gray. .N. LUNATIA RECTILABRUM. PI. 35, fig. 28. Subglobose; spire conical, subscalariform ; labrum straight in the middle; umbilicus moderate in diameter, profound. The specimen figured is to the eye as perfect as when first entombed in the Cretaceous ocean’s bed. SOLIDULUS, Fischer. SOLIDULUS LINTEUS. Pl. 35, fig. 10. Elliptical, with very numerous close revolving lines, most distinct on the inferior half; interstices regularly and elegantly striated transversely. | A beautiful species, but the specimen much distorted, which I have endeavored in the figure to restore to something of its original shape. The above genus is identical with Actzon, Montfort, and TorNATELLA, Lam. BULLOPSIS, Conrad. Subglobose ; spire depressed ; aperture wide; columella biplicate. The spire in this shell is sunk like that of Butta. I have seen no other shell resembling this. BULLOPSIS CRETACEA. Sculpture resembling that of SoLipuLus, consisting of minute impressed lines; aperture wide in the middle; plaits prominent. 1 Length 4 inch; width 4 inch. CEP Fd ASO OWS BACULITES, Lam. BACULITES TIPPAENSIS. PI. 35, fig. 27. Acutely ovate, smooth, with profoundly sinuous lines of growth, which rise on the sides, and curve downwards on the back and front; shell splendidly iridescent ; back regularly rounded ; front slightly con- tracted, or with depressed lines on the sub-margin. This species can be readily distinguished from B. ovata, Say, by its acutely ovate outline viewed in a tranverse section. The substance of the shell appears to be in perfect preservation, beautifully iridescent, and the lines of growth run profoundly oblique downwards to the front, which they cross in nearly straight lines. 7 Specimens show the interior free from sand, with the foliated septa as perfect as when the animal inhabitant was alive. In most specimens the front is obtusely carinated as in the following species : NEW CRETACEOUS FOSSILS. 335 Bacuuites Sprimant. Pl. 35, fig. 24. Obtusely ovate; back flattened, front a little raised or obtusely carinated; sides with distant, very thick, obtuse, curved, remote ridges. This is a beautiful species, even more highly iridescent than the preceding. ‘The lines of growth are similar in form to those of the former species but more strongly defined. The septa are too imperfectly exhibited to be defined by a drawing. The substance of shell thin. Dedicated to its discoverer Dr. W. Spillman. SCAPHITES, Parkinson. ScAPHITES IRIS. Pl. 35, fig. 23. Substance of shell very thin, highly irides- cent; whole surface ornamented with pyramidal, distant tubercles, the inter- vening spaces smooth; back rounded, with two rows of tubercles, another row runs along the junction of the lateral with the dorsal margin; sides flattened. A fragment of this beautiful species exhibits the extremely thin septa, in perfect preservation and free from sand. The form of the septa is very unlike that in S. Conradi, to which species I referred it in my introductory remarks. Pl. 30, fig. 31. Outlines of a species of CyTHERInA, Lam., somewhat enlarged. Symmetrical, smooth, subrostrated at each end.

Habitat—Tangier, Andalusia, neighborhood of Chiclana, S. Spain. One adult specimen in Mus. Acad. Nat. Se. and two young (Bradybates poireti and Triton nycthemerus) Dr. Wilson, Bonap. Collection. Gen. Remarks.—Pleurodeles is related to the Tritons, but differs from them in its large flattened head, its lengthened ribs, its long tail; the nares are more widely separated than in the Tritons, the eyes more elliptical, the upper eyelid more de- veloped, according to Micheelles. (Isis, 1830, p.191.) The parotids are also wanting in the Tritons. P. Watli is found abundantly in cisterns near Cadiz, in the south of Spain. We have in the collection of the Academy a single specimen, labelled Triton nycthemerus, belonging to the Bonap. Collection, which is without doubt the young of Pleurodeles Watli. Gray observes that it is, perhaps, the young of 7. marmoratus or Triton cristatus, but the teeth are arranged as in Plewrodeles and not as in Triton, and the tongue is alsothat of Plewrodeles, which is quite different from the tongue of Triton: BRADYBATHS, Zsch. Char.—Head round, occiput swollen, but the forehead depressed ; eyes small and far apart; feet very short, toes small, but free throughout; body short, broad, the the sides, as in Plewrodeles pierced by the ribs; tail shorter than the body, broad at the base, roundish, towards the end more angular, differing remarkably from Pleuro- deles, inasmuch as the latter has a very long sword-like tail; tongue small, rounded like a firmly attached wart; no parotids; at the root of each foot two tolerably large swellings.

Char.—Dark brownish yellow, with dark colored spots, and thickly covered with fine warts. Length Habitat.—Spain. Gen. Remarks.—Dumeril and Bibron are inclined to the opinion that this genus may be only the young of Pleurodeles, coming from the same localities and possessing many of its characters. “ We have inthe Bonaparte Collection, now belonging to the Academy of Nat. Sciences, a single specimen marked Bradybates powretr, which is evidently a young Pleurodeles, but the tail is longer than the body.” ‘Tschudi says “Zahne ganz Plethodon,” but this is probably an error.

Remarks.—The coloration varies somewhat in different specimens. Of 25, now before me, recently captured at Altoona, Pa., about 225 miles from Philadelphia, by Dr. Wilson, Dr. Leidy and Mr. Conrad, I find that the young are much more thickly spotted than the adults, which above present the confluent appearance of the spots upon the sides; the abdomen and under part of the tail are bluish, sometimes very minutely spotted with white, that part of the tail usually so; the upper part of the head is generally free from spots, but a large one may often be seen upon the skin; palms of soles of feet brick-dust red. Some of these specimens have a decidedly granulated appearance, and are covered all over upon the back with very minute white spots interspersed between the larger ones. The specimens from South Caro- lina and Georgia present no differences in the coloration ; but among those of the former is a marked variety noticed by Dr. Holbrook, entirely black above without spots; chin and throat yellowish; abdomen dark brown, sometimes minutely white spotted.

Char.—“ Skin granulated, of a brownish green, often very deep upon the back and sides; with large black spots, and small white salient spots, especially upon the sides; under part of the body of an orange yellow, with black irregular spots; inferior portion of the tail most often of a golden yellow, without spots; throat brown, with some yellow marks, without large black spots, but small brown lines, and minutely punctated with white. The male carries upon the back, especially at the period of fecundation, a large brown membranous denticulated crest, which commences upon the anterior part of the body, and is continued along the spine as far as the pelvis, where it disappears; the tail, which is much compressed and large in the middle, presents also, above and even beneath, a crest, the superior one of which is also - slightly denticulated or festooned ; the crest of the female is not so much developed, CADUCIBRANCHIATE URODELE BATRACHIANS. 359 and the underpart of the tail presents constantly a line or vitta of a yellow color, more or less marked.”—Dum. et Bib. Duméril and Bibron, who have had frequent opportunities of observing these animals alive, describe three varieties—l. Very large, of the size of Salamandra maculosa; blackish above, yellow spots under the jaw in the male, and under part of tail in the female yellow, without spots. Var. 2. A little more than half the size of the first. Brownish above, or greyish in the males, yellow color of abdomen less deep; these varieties perhaps the affect of age. Var. 3. Triton carnifex; females of small size; no dorsal crest, replaced for the most part by a yellow line prolonged upon the tail. What distinguishes most, however, this variety is the pale yellow or whitish color of the abdomen, with large black rounded spots; but rarely spotted in the middle region. Length 4% inches long, (Fr.) Habitat—Common in Europe, (abundant in N. of France,) found in the coldest regions, (N. Africa, Schlegel.) 77 specimens in Mus. Acad. Nat. Sci., Bonap. col., presented by Dr. Wilson; one specimen without name or locality. TRITON MARMORATUS, JLatreille. Char.—Body rough or warty, sometimes of a light green, or more or less deep with marbled black spots, more or less confluent, or with spots of a brownish red upon a ground of deeper brown; for the most part a yellow line, or band, or of a beautiful carmine red, extending the whole length of the back from the nucha as far as the middle portion of the tail; the under part of the body varies, sometimes it is black or of 2 venous red, with white points, more or less sparse, and grouped together; some- times it is very pale.’—Dum. et Bib. Duméril and Bibron, who have especially observed this Triton, living and of dif ferent ages, describe three varieties: 1. A line of a beautiful red, almost carmine, extends all along the middle line of the back and tail, changing sometimes into orange yellow ; throat and abdomen reddish venous brown, with small white points ; under part of the tail of the same red color. 2. Brown above, with avery pale yellow dorsal line; no spots upon the under part of the abdomen; under part of the tail red or orange yellow. 3. One fourth the size of the first, perhaps the young; light grey above, with a dorsal yellow line; rounded spots and black markings upon the sides; sides of a uniform brown color; under part of the body reddish, without any spot, or very distinct white spots. “ Most authors,” observe Duméril and Bibron, “regard Triton marmoratus as a variety of Triton cristatus.” Habitat Whole of France, especially the southern portion. Remarks.—We have in the Bonaparte collection a single specimen marked Triton ae a kates) Bt pais eh aca a hoe re 360 HALLOWELL ON THE marmoratus, which corresponds precisely with the figure of the same in the Fauna Italica, of which it is, most probably, the original, which differs from the above des- cription.: It is extremely rugose, of a uniform dark ash color; the markings upon the sides very indistinct; an orange line under the tail; abdomen light orange, with numerous irregularly shaped black spots of different sizes; more or less confluent. It resembles very much some of the specimens of Triton cristatus, but there are no round black spots upon the sides; and the dorsal line is absent. According to Kauf, Triton marmoratus is found 6 inches in length, and exists also in the south of Spain. According to A. Dugis, the tail is round in the winter, flattened at the nuptial season. According to Duméril and Bibron, Triton nycthymerus is Triton carnifex, the young of Triton marmoratus, but the specimen in the collection of the Academy, marked Triton nycthymerus, is very different from carnifec and marmoratus. The tongue is small and free behind, asin Pleurodeles. Triton nycthymerus is found in the Tyrol and Picardy. Schlegel remarks that Zriton marmoratus is sometimes perfectly smooth, without the slightest trace of tubercles. It is found, also, according to him at Tunis. Two fine specimens in Mus. Acad. N. S., presented by the Garden of Plants, corres- ponding in every respect with the description of Duméril and Bibron. TRITON PALMATUS. Char.—“ Skin slightly granular, of a yellowish brown above, with two salient dorsal lines, parallel to the salient line of the spine; the under part of the body of a beautiful deep orange color, more yellow towards the sides; the posterior extremities of the male, in the commencement of spring, of a darkish brown, with the five toes almost entirely palmated; the females of a lighter color, with the tail almost round, especially after having been a long time out of the water.’—Dum. et Bib.

Duméril & Bibron describe three varieties of the males and as many of the females of this species: 1, with a very distinct crest, with the toes sometimes palmated or semi-palmated, then becoming simple or not lobed; teniatus, Wolf, Gravenhorst, Schneider ; punctatus, Latreille, Merrem ; palmipes, Daudin in Latreille. 2, crest scarcely distinct, with the toes simple; punctatus, Daudin. 3, males in which the crest of the back and tail are more apparent, as well as the membranes bordering the toes. Of the females, the first variety are brown above, with two longitudinal lines of a deeper color upon the back, and spotted with black beneath ; beneath small black spots in the intervals between the large rounded spots, likewise upon the borders of the lower jaw; tail yellow beneath. Length 2 inches 6 lines. Habitat.—Very common in the neighborhood of Paris, and other parts of the north of France; aquatic, oviparous. 62 specimens in Mus. Acad., Bonap. collection, presented by Dr. Wilson, labelled Triton lobatus ; two or three of them labelled Nillson appear to be cristatus. According to Dugis the exigwis is a young palmatus, and abdominalis, Latreille, the young of the female of punctatus. TRITON VITTATUS, Gray. Sp. Char.—“ Body smooth, of a greyish white color, with large black points or. spots arranged in longitudinal lines; a large yellow or reddish band, bordered with black, above and below, extending upon the flanks, from the axillee and two-thirds or more of the side of the tail; under part of the belly yellow or red, marked with black points more or less abundant.’—D, & B. t.ix. p. 144. Habitat.—France and England. One specimen in Mus. Acad. Nat. Sci., presented by the Garden of Plants, another larger, with the lateral stripe on both sides broad and well developed, by Dr. Bache, forming part of the Green collection. Length of largest specimen 3 inches 10 lines ; of tail 1 inch 9 lines. Gen. Remarks.—According to Duméril and Bibron this is a doubtful species, being intermediate in its characters between 7. alpestris and 7. punctatus. It is the Lisso- triton palmipes of Bell, (British Reptiles,) the Molge and Ommatotriton vitiatus of Gray. TRITON PYRENazUS, Dum. & Bib. Char.—Body warty or very rough, with salient points, brown upon the head and sides, with a large yellow colored or safron dorsal ray, continued almost from the 92 362 HALLOWELL ON THE nucha to the end of the tail, but denticulated irregularly with brown upon the edges, and marked with isolated salient black points, few in number, upon the dorsal region.

(Gen. Cynops, T'schudi.)—D. & B. Habitat. Japan. Gen. Remarks—Dumeéril and Bibron say that Tschudi has separated this animal from the Tiritons, giving it a name indicative of no character, supposing that the tongue was adherent throughout, but in the account of this genus in the German of Tschudi, the only mention I find made of the tongue is that it is “ sehr klein,” very small. The generic characters are based upon the differences in the osteology of the skull, which, he says, is quite different from that of Triton. Not having the specimens, we cannot determine this point. Gray mentions the tongue as adherent, scarcely free on the edges.—Cat. Br. Mus., p. 24. Duméril and Bibron consider it as allied to Huproctus, Bonaparte and Gené. Du- méril and Bibron, besides the above, describe five species from the Pyrenees, collected by Bibron, viz. : rugosus, cinereus, repandus, punctulatus and Bibroni, which according to A. Dugis and M. Gervais, as stated by them, are varieties of Huproctus ruscont. For description of them, see their work, p. 150—154, t. ix. DIEMYCTYLUS, Raf. Char.—Tongue small, ovoid, adherent in front and superiorly, somewhat less at the sides; no transverse palatine teeth ; two longitudinal series of palatine teeth in contact in front, diverging posteriorly ; posterior nares quite large ; two longitudinal ridges upon the cranium in contact in front, diverging posteriorly ; a bony bridge above the orbit, as in Cynops and Huproctus ; spinous processes of vertebrae quadrangular, com- pressed, laterally well developed; three foramina on the sides of the head, not com- municating with the mouth; first and fifth toes rudimentary. Gen. Remarks.—Diemyctylus, as observed by Prof. Baird, appears to be closely related to Cynops, Tschudi, Molye pyrrohogastra, Boié.

In Cynops there are altogether 40 vertebrze and 16 dorsal,* the pelvis attached to the 15th and 16th. The ribs are larger and stouter than in the European Salamanders ; the spinous processes very strong and broad, arranged like a comb; vertebree of the tail much compressed, with strong processes below. See Tschudi, Batrachier, p. 60. DIEMYCTYLUS VIRIDESCENS, Raf. Ohar.—Olive colored above, with ordinarily from three to eight small circular spots, bordered with black, upon each side of the dorsal line; abdomen olive, dotted with black ; tail more or less compressed, longer than head, neck and body; no parotids. _ Length 3 inches 9 lines.

Char.—Skin granulated, of an orange color, deeper above; on each side of the back a row of small, subrotund, crimson spots, bordered with black ; tail compressed, of same length as body. Total length 2 inches 8 lines. Syn. Salamadra symmetricus, Holbrook, North American Herpetology, vol. v. p- 07, Pl. xvii. Habitat.—Pennsyivania and Delaware. Gen. Remarks.—This animal, as Dr. Holbrook remarks, appears to be distinct from viridescens and Triton dorsalis, Holbrook, the latter living in the water, the other being an inhabitant of the land. Triton dorsalis,t (Notopthalmus miniatus, Raf.,) and Diemyctylus viridescens, (2. symmetrica,) appear to be the same, the difference in their form and color being attributable, in all probability, to differences of habitat and sexual pecu- liarities. We have some specimens without any spots, others with only one, and others with from three to eight on each side; the spots in all the specimens are small, round, and bordered with a margin of black, and the body and abdomen more or less minutely dotted with black. In some specimens, however, the upper surface is orange, without spots. There may be described the following varieties—Ilst. Orange- colored above, lighter upon the head, with three or four small, round spots, bordered with black, on each side; underparts orange, sparsely dotted with black; a few black * 14 according to Schlegel and 16 in Triton cristatus. + From the longitudinal stripe alone the middle line of the back. 364 HALLOWELL ON THE dots upon the tail, (Zriton symmetricus, Holb.) It is to be observed, however, that these spots are not always symmetrically disposed, but in the specimen before me, the first on the right side is about two lines in advance of the same on the left, and the number of spots is not always the same on each side; sometimes two spots on the right side, four on the left, much smaller than the others and granulated. 2d. var. Same distinction of spots, skin almost smooth, abdomen more thickly dotted with black; under parts orange, (millepunctatus, Storer, punctatissimus, Wood,) or with a row of small circular spots, five in number, on each side, not very regularly disposed ; probably an advanced age of No. 1. 4th. Tail more or less crested above and below; four or five or eight circular spots bordered with black on each side, the two first on each side of the occiput, as in some of the other varieties; body above and below very minutely dotted with black ; sides © of tail black spotted; spots large upon the root, nearly as large as those of Triton eristatus. Inu some of them the circular spots are quite indistinct, or united to each other forming longitudinal bands; in others there are no circular spots whatever, the back being covered with brownish irregular lines; a longitudinal band of black run- ning from the throat along the side of the head, neck and abdomen, and continued along the tail; two black longitudinal lines on each side of the salient dorsal line, and a longitudinal line on each side; the sides of the body, as well as the tail, are spotted with black, the spots much larger upon the tail; under parts yellow, very minutely punctated with black, (m¢llepunctatus, Storer.) We are informed by Prof. Leidy, the vermillion colored specimens were found invariably upon land, and the olive colored ones always in the water, or in marshy places, so that it would appear that these, as stated by Prof. Holbrook, are really distinct species. It is to be regretted, however, that we do not know more of the habits and mode of life of each. We have received to-day, through Dr. Wilson, Prof. Leidy and Mr. Conrad, who have been spending several weeks at Cresson, at the top of the Alleghanies, about 225 miles west of Philadelphia, at a height of 2300 feet, a considerable number of specimens of .Diemyctylus miniatus, Raf., (iS. symmetrica, Holb.,) and Diemyctylus viridescens, Raf., (Triton dorsalis, Holb.) The former present nothing remarkable, and have been sufficiently well described. The latter present the following appear- ances: These 13 specimens of Diemyctylus viridescens resemble each other very closely. They are of an olive color above, deeper in some specimens than in others, with a vertical yellow line extending from the occiput some distance upon the tail; on each side is a row of vermillion spots bordered with black, varying in number, but usually five or six on each side; sometimes.a few smaller ones may be observed irregularly disposed.

Toul wo on =I — ART. XXIIL—On Trigonophrys rugiceps. By How. HaAttoweEny, M. D. Gen. TRIGONOPHRYS, nob. Ohar.—Head very large, depressed; upper eyelid triangular; tongue large, sub- circular, notched in front and posteriorly, more deeply behind, attached anteriorly, free laterally, and in its posterior half; upper maxillary teeth large, conical, recurved, sharp pointed ; two groups of vomerine teeth on a line with the anterior margin of the posterior nares, nearer to these than to each other; posterior nares large, sub- circular; eustachian foramina of moderate size; no vocal vesicles either internal or external; tympanum indistinct; four fingers completely free; toes palmate at their base only ; first cuneiform bone presenting a prominence externally, with a well defined projecting edge; transverse processes of the sacral vertebre not dilated. TRIGONOPHRYS RUGICEPS. Plate 36. Sp. Char.—Vomerine teeth in two small patches at the inner edge of the internal nares ; dental apophyses very distinct ; toes pointed, palmate at the base only; fourth toe much longer than the others ; head presenting numerous asperities upon its upper surface; body pustulated above and upon the sides; abdomen smooth; two glands, triangular in shape, upon the upper surface of each thigh, and two larger ones upon the breast ; color olive or violet above with numerous large dark colored ovoid spots margined with white; the interspaces in the young and middle aged of a beautiful rose color ; extremities olive colored above, with large and broad bands of black, margined with white, the interspaces more or less tinged with rosy red; abdomen white, black spotted. Description.—The head is very large, broader than long, flattened or very slightly convex above, depressed, the inclination in front not very abrupt; the nostrils, which are two crescentic openings, are situated about midway between the margin of the upper jaw and the inferior border of the orbit, nearer to the former, four lines apart; eighty-two teeth may be counted in the upper jaw, the anterior and middle ones Jonger than the posterior, concave posteriorly ; their convexity presenting forward, very much enveloped at the base ; two movable bucklers beneath the skin, posterior 368 HALLOWELL ON to the occiput, suboval in shape, their upper surface, as well as that of the head and its sides, rough, from the numerous asperities with which it is covered ; body more or less covered with rounded tubercles above ; thighs granulate posteriorly ; two well marked glands, triangular in shape, upon the upper surface of each thigh near the groin; two others, much larger, are seen upon the breast, between the anterior ex- tremities; abdomen, throat and under surface of extremities smooth; tubercles beneath the fingers and toes ; those at base of thumbs and upon palms much larger ; projection of the cuneiform bone much developed, with a well defined edge. Coloration.—The ground color above is violet or olive; the body and sides pre- senting numerous large dark colored ovoid spots, with a very narrow margin of white ; the interspaces between these spots, in the young and middle aged specimens, are of a beautiful rose color ; extremities olive colored above, with large and broad bands of black, margined with white ; the interspaces more or less tinged with rosy red; under parts white, mingled with yellow; chin and throat with numerous black spots; abdomen also black spotted, but much less thickly than the chin and throat, sometimes without spots. Dimensions of the largest specimen.—Length of head 1 inch 4 tines; greatest breadth 2 inches 34 lines; breadth of bucklers 1 inch 72 lines; length of body 3 inches; breadth 3 inches 2 lines; length of anterior extremities 24 inches; of arm Linch 2 lines; of forearm 1 inch; of palm and longest finger 11 lines; of thigh 1 inch 4 lines; of leg 1 inch 1 line; of sole and longest toe 2 inches; of posterior extremity 4 inches. Anatomy.—The structure of the skull in this genus resembles that of Ceratophrys, but it is comparatively longer, and the teeth are much more highly developed. The orbitar foramina are widely apart in Ceratophrys. The skull in Trigonephrys is covered all over with well marked rugosities, the temporal fossee are much larger in the latter; the skull itself is triangular in shape, depressed in front, hollowed between the orbits, consisting of a solid bony case, with traces of sutures only in front of the latter ; the orbitar foramina are subcircular in shape, measuring 42 lines transversely, and are three lines apart; the occipital foramina are large and oval; upwards of fifty recurved conical teeth may be counted in the upper jaw, the anterior much the larger; the openings of the internal nares are oblong and quite large; two small ’ bunches of palatine teeth are situated at their inner extremities on a line with their anterior margin; the nostrils are small, three lines apart, about four lines from the anterior extremities of the cranium. ‘There are eight vertebra, exclusive of the atlas and sacrum; the spinal processes of the first are much more developed than those which follow; the transverse processes are seven in number, of these the second and the third are the longest, the former measuring five lines in length; the TRIGONOPHRYS RUGICEPS. 369 transverse processes of the sacral vertebree measure three lines in length and are thicker at their external extremity ; the os coccygis is depressed, nine lines in length; the iliac bones and those of the extremities present nothing remarkable; the sternum does not differ materially from that of Ceratophrys. The difference in the structure of the skeleton in this anima] and Rana pipiens, or common bull-frog, is very striking ; indeed, it could hardly be greater in two genera belonging to the same family. The orbitar foramina are more than double the size; the nasal openings very large; the scapula remarkable for their great breadth, and the ribs are of nearly equal length. Viscera.—The skin is very loosely attached to the thin and semi-transparent fascia covering the muscles, its inner surface presenting numerous inosculating small vessels distributed over its surface; immediately beneath this fascia two muscles shew them- selves on each side, broad at their base and fanlike, the anterior inserted into the upper surface of the humerus near its proximal extremity, the inferior into the symphisis pubis. On cutting into the peritoneum ; the /iver consists of three lobes occupying the right and a portion of the left side of ‘the abdominal cavity, the right lobe trefoil in shape, the middle somewhat pyriform, and the left more or less quadrangular in shape, its anterior margin presenting a waved outline; the gall bladder is quite distinct ; the heart lies immediately above the liver, enclosed in its pericardium, and consists of a ventrical and two auricles, the left comparatively empty, the right much distended with clots of coagulated blood; the ventricle measures six lines in length by five in breadth ; the esophagus communicates with the stomach by a large opening; the latter is a large membranous sac, two inches five lines in length, by an inch and a half in breadth at its greater extremity ; it occupies, when extended, nearly the whole of the left portion of the abdominal cavity; on cutting into it, it was found to contain numerous Coleop- tera, (Trox,) a portion of vegetable matter and the half digested skeleton of a hyla. The intestine measures 14% inches (Fr.) in length from the pyloric orifice to the commencement of the cloaca, the diameter of which, as usual, is larger than that of the intestine, and measures in length about 53 inches. The ovaries are of a black color, and contain a great many eggs of a yellow color, of the size of a pin’s head ; the Jungs lie posterior to the other viscera, and, when somewhat distended, reach nearly the whole length of the abdominal cavity ; the cells, as usual in the frogs, are quite large, and divided by membranous septa ; the fatty bodies are much developed, and present numerous subdivisions, thirteen on the right and seven on the left side ; there is a very small triangular spleen ; the hidneys are one inch in length by three in breadth. Ina specimen of Ceratophrys, about half the size of Vrigonophrys, the liver presented three lobes deeply cleft, but the right lobe was destitute of the trefoil arrangement of the former, the anterior margin being nearly straight, the lobe itself triangular in shape; the specimen having been immersed in strong alcohol, the 4 370 HALLOWELL ON TRIGONOPHRYS RUGICEPS, viscera are shrunken, but making allowance for this and its smaller size, the stomach appears considerably less, being not more than an inch and a half in length, and the intestine is much shorter, measuring but four inches three lines in length ; the fatty bodies are much foliated, the kidneys measuring eight lines, the testes four in length. Gen. Remarks.—The general shape of the head in this genus, resembles very much that of Ceratophrys, along side of which it should be placed in anatural arrangement, but it differs from Ceratophrys in the form of the eye-lids, which do not terminate in the latter, and the form of the body has no resemblance to that of Trigonophrys. The teeth also are different. In Megalophrys, a genus inhabiting Java, and comprising but one species, (JZ. mon- tana,) the first cuneiform bone presents no external prominence, which in Trigon- ophrys is remarkably large. We, therefore, although not having in our collection any of the allied genera, with the exception of Ceratophrys, venture to propose for this singular and beautifully colored frog a new name. ‘The maxillary teeth form one of its most striking characters, being larger than those of any species of frog with which we are acquainted, those of the largest bull frog being considerably smaller, as well as those of the large Surinam frogs in our collection. In Cystignathus ocellatus, however, the vomerine teeth are much more developed.
