VOL. I. NEW YORK, NOVEMBER, 1907. No. 1. 



NOTE. This number of the Bulletin comprises papers read before 

 the Club in May, June and September, 1907. With us the word 



conchology is not limited in meaning to the study of shells only, but 

 extends to the study of mollusks in general, both recent and fossil ; 



and the word shell is often used as as synonym of mollusk. 



Abnormal Shells 



BY S. C. WHEAT. 



A specimen of Pyramidula alternata Say (fig. 5) found near Ithaca, 

 N. Y., is turreted, the suture being placed far below the carina of the 

 preceding whorl. The carina is unusually sharp. The animal was in 

 all outward respects normal. 



Another specimen (fig. 4) found in the same vicinity was flat, the 

 suture being above the carina and deeply impressed. 



A dead shell of Polygyra thyr aides Say (fig. 6) found on the 

 Palisades near Creskill, N. J., has a deep notch in the lip. The notch 

 begins at the periphery of the body whorl and extends downward to 

 the base. It is 3 mm. deep and 4 mm. wide. The glaze within the 

 lip and the lines of growth in the epidermis behind it are normal. The 

 denticle is in the usual position. 



Another specimen found alive at Summit, N. J., had formed a lip, 

 then carried the shell forward 5 mm. and formed a second lip. This 

 specimen has no denticle on the pilar lip. The shell between the two 

 lips has no epidermis, and has coarse wrinkles of growth that look like 

 attempts at forming lips. A similar specimen of P. tridentata is figured 

 in "Manual of Amer. Land Shells, Binney," p. 291. 




A dead shell of Polygyra tridentata Say (fig. /), found under the 

 Palisades near Fort Lee, N. J., had formed the lip and denticles, and 

 afterwards had lost three-fourths of the body whorl. The shell was 

 then carried forward about 3 mm. and a new lip and denticles were 

 formed. Mr. F. H. Ames has shown me a similar specimen from 

 Wyoming Co., N. Y. 



The cause of this injury is a puzzle to me. If a mouse gnawed the 

 shell why did he not persevere and secure the dainty morsel? Was 

 he interrupted by a hawk or a snake? Did water find its way into 

 the shell in winter, freeze and burst the frail vessel? Or did a fall 

 from the rocks cause the fracture? 



I have found several specimens of Polygyra albolabris at the foot 

 of a ledge with fractured shells. In some instances ihe evidence of 

 a fall was conclusive. Beside the patient lay the fragment of a mush- 

 room on which the unfortunate mollusk had been feeding. The rest 

 of the fungus was clinging to its stem ten or twelve feet up the steep 

 bank. The break in this shell was exactly opposite the aperture. The 

 next morning the snail was crawling about with its head thrust 

 through the fracture. For four days the foot and head were not 

 entirely withdrawn into the shell. On the fifth morning the head was 1 

 thrust from the natural aperture, and in one week the large break was 

 closed by a rude patch of epidermis and shell. This shell is now in 

 my collection.

A New Varietel Form of Turbo Petholatus, Linn 



BY MAXWELL SMITH. 



In the American Museum of Natural History of New York is a 



series of Turbo petholatus which seems worthy of note. Specimens 

 are represented in the Haines, Jay, Crooke and Stuart collections. 



Out of fifty-two specimens eleven are heavily shouldered (fig. 2), 

 seven show a tendency toward shouldering and the remainder are 

 typical (fig. i). This extreme form justifies a varietal name and to 

 recognize its character I would suggest var. liuuierosus. 



5 




A number of varieties have been recorded by Tryon and others 

 based on the coloration and marking, but many of these are not strong. 

 In works that I have examined no figures show this extreme form. In 

 the variety the aperture is less rounded than those of the typical shell. 

 The radulas were not preserved with the shells, and science must wait 

 for new specimens to ascertain what difference, if an}', extends to the 

 dentition. 



Fig. i represents the typical and fig. 2 the variety hurnerosus, natural 

 size. All of the individuals are labeled Philippines. 



I am indebted to Mr. Enoch Bolles for the drawings which accom- 

 pany this article. 



Shells in City Gardens and Ponds 



BY S. C. WHEAT. 



In my garden in the heart of Brooklyn are innumerable Vallonia 

 pulcJiclla Miillcr. I have taken fifty good specimens from a space four 



inches square. In midwinter sixteen were found packed in a bit of 

 hollow stem of a plant, the shells fitting snugly in the orifice, and all 



occupying a little more than an inch in length. In November I have 

 found them active under a half-inch of frozen earth and snow. One 

 of these beautiful creatures took its winter nap from October to March 

 on the stem of a tropical tree in my window, where the sun blazed 

 upon it for three hours every bright morning without once moving. 



These specimens are all of the smooth variety. Twelve shells placed 

 side by side cover a line one inch in length. They are more abundant 

 near houses than in large fields. 



In a foundation from which a house was burned several years ago 

 a prosperous colony of Vitrea ccllaria M filler were found; also many 

 fine specimens in a heap of coal ashes in the back yard of a tenement 

 in a crowded part of Manhattan. This beautiful creature in its pure 

 glistening shell has a liking for the dark corner of the cellar where 

 the cask of Burgundy is stored. 



Under stones in a vacant lot were several fine Zonltoidcs arborcus 



Say. Eight years before, the last forest trees had been removed from 

 this block and for fifteen years it had been surrounded by paved streets 

 and blocks of brick houses. 



Where forest trees still shade a vacant lot Polygyi'a tJiyroidcs Say 

 is still found. 



I have fine specimens of Liuinaca anricnlaria Linnaeus, Planorbis 

 trirolris Say and a Physa from an artificial lily-pond in Prospect Park, 

 Brooklyn. The same shells have been found in private grounds in 

 the vicinity. 



Anodonta implicata Say is found in the large lake in Prospect Park.

Phorus, fXenophora) Gonchyliophora, Born 



BY F. W. WEAVER. 



Shell trochiform, usually thin and brittle, except where other objects 

 are fastened to it. Whorls flattened, upon which are fastened bits of 

 stone, coral or shells. Umbilicus narrow, sometimes covered. 



In the Phorus the Conchologist has a rival, for this interesting- 

 species is also a collector of shells with which it adorns its habitation. 

 Usually they pick up an indiscriminate variety of bits of stone, coral 

 or shells, using care that no sharp edges are turned downwards, to 

 impede its movements. A specimen in my collection seems, in its young 

 state to have had a liking for bits of black stone. As it grew larger 

 it selected only a certain species of bivalve shell, which, owing to their 

 smooth convex surfaces, could not be fastened securely, and a number 

 had dropped off, leaving an indentation. The animal, apparently taking 

 notice of the fact, began using Cerithiums, fastening them by the apex, 

 and embedding them so securely that they could not be removed with- 

 out breaking its own shell. 



A fine specimen in the British Museum has adorned its shell almost 

 exclusively with Cerithiums. To select these from among the many 

 varieties with which it came in contact must have required some 

 intelligence. They are deep water shells and are most numerous in the 

 seas of China and Java. 



Owing probably to the mass of objects which the creature places 

 upon its shell its movements are very clumsy and when crawling about 

 it staggers and rolls as if overburdened with its heavy load. 



List of Long Island Shells 



BY S. C. WHEAT. 



The shells named in this list were found by the writer or by a mem- 

 ber of the club working with him, except where some authority is 

 mentioned. Staten Island is included in the area examined. Most of 

 the collecting was done in August, 1903, in the vicinity of Centre 

 Island, lying between Oyster Bay, Cold Spring Harbor and Long Island 

 Sound. No deep-water dredging was done. Only a small part of Long 

 Island has been w r orked by members of the club.

TO 




Shall We Have an American Concholo^ical Society ? 



For half a century tlic Conchologists and shell collectors of Brook- 

 lyn have held frequent meetings to compare notes and view collections. 

 For several years they formed a Section in the Department of Natural 

 History of the Brooklyn Institute of Arts and Sciences, hut withdrew 

 from that hody four years since and organized the Brooklyn Concho- 

 logical Club. 



Letters of inquiry about the Club were received from time to time 

 and it seemed that all parties would be mutually benefitted if students 

 of the Mollusca in all parts of the country were united in one organ- 

 ization and provided with a means of communication and exchange of 

 opinions. 



At the regular meeting of the Club in May, 1907, it was resolved to 

 receive members from all parts of North America, to adopt for the 

 name of the larger body "The American Conchological Society/' and 

 to cail the first annual meeting in October, 1907. 



On motion the following were appointed a committee to organize 

 the society, elect officers and make rules to govern it until the first 

 annual meeting and to report to said meeting : Silas C. Wheat, C. 

 Dayton Gwyer, Maxwell Smith, Frank H. Ames, Fred W. Weaver, 

 A. di Costa Gomez, Charles A. Dayton, D. W. Ferguson, W. H. 

 Weeks, A. W. Lawrence, and J. W. Judd. 



The committee arranged for an official organ (a monthly publica- 

 tion), and for one or more bulletins each year, enrolled members, 

 secured a room for the annual meeting in the American Museum of 

 Natural History, prepared a prospectus of the new society to be cir- 

 culated as soon as people should return from their vacations, and 

 elected the following officers : President, Dr. H. A. Pilsbry, Curator 

 of Dep. Mollusca, Academy Natural Sciences, Philadelphia ; Vice- 

 President, Louis A. Gratacap, Curator American Museum Natural 

 History; Treasurer, Silas C. Wheat, of Brooklyn; Secretary, Maxwell 

 Smith, of the Amer. Museum Nat. History. 



An independent movement with the same end in view took place in 

 Boston during the recent session ,of the International Congress of 

 Zoology, August 19-24, resulting in the appointment of the following 

 Committee: Dr. William II. Ball, of Washington; Dr. H. A. Pilsbry, 

 of Philadelphia; Elizabeth J. Letson, of Buffalo; Silas C. Wheat, of 

 Brooklyn ; and John Ritchie, Jr., of Boston. 



The slow pace of the correspondence that followed between the 

 scattered members of the two committees caused a delay in issuing 

 the prospectus and made it necessary to abandon the plan for a general 

 meeting in October. 



Both committees desire harmony and the establishment of the 

 society upon a secure foundation. In place of the prospectus by the 



1 1 




Brooklyn committee, the "suggestions" by Dr. Dall are presented. All 

 persons interested in the formation of an American Conchological 

 Society are requested to address the Secretary, Maxwell Smith, 265 

 West 72nd Street, New York, N. Y., stating intention to join the 

 society, request for further information, or criticism of the suggestions, 

 and address of persons to whom this paper should be sent. We invite 

 a free expression of opinions. 



The members of the Brooklyn Club prefer that the dues should not 

 exceed two dollars per annum, and life membership forty dollars. Mr. 

 C. W. Johnson, of the Boston Society of Natural History, writes : "I 

 would make it $2, certainly not over $3, and the life membership $50." 



Memorandum of Suggestions for the Organization of a National 

 Conchological Association or Society, by Win. H. Dall, Oct. 15, '07 



NAME. The AMERICAN Conchological Society would be better than 

 '\ATIOXAL,'" as Mexican, Cuban, or Canadian members, whom it would 

 be desirable to include, might object to the term "National" as exclud- 

 ing them. 



OFFICE. To promote intercourse between the students of Mollusca, 

 recent or fossil, in North America, the Antilles and Hawaii; to en- 

 courage the study of Mollusks by meetings and publications, or other 

 means suitable for the purpose; and to interest the general public in 

 the study of shells. 



OFFICERS. The officers shall comprise a president, a vice-president 

 for each section, a general secretary and a treasurer, and an executive 

 council consisting of nine members. 



MEMBERS. The membership of the Society shall be divided into 

 the following classes : Patrons, life members, active annual members, 

 associates, and corresponding members. A limited number of honorary 

 corresponding members may be authorized by the council if deemed 

 desirable. 



QUALIFICATIONS. A patron shall be a donor to the Society of any 

 sum exceeding the total of two life membership fees, and shall be en- 

 titled to all publications of the Society and to receive gratis any 

 periodical which may be distributed, as its organ, to the members by 

 the Society. A life membership may be secured by the payment to the 

 Society's treasurer of the sum of one hundred dollars ; active member- 

 ship by the annual payment in advance of the sum of five dollars; asso- 

 ciate membership by the annual payment in advance of one dollar and 

 a half by American associates and two dollars by foreign associates or 

 corresponding members. Honorary members may be relieved of pay- 

 ment at the time of election, by the vote of the executive council. 



12 




All members sball be nominated in ilie council, by the application 

 of any three members nr assneiates in good standing through the secre- 

 tary, and sball be eleeted by a majority vote of the council, but no 

 election sball be deemed effective until the treasurer lias received the 

 lirst annual subscription from the nominee, and the publications of the 

 Society shall not be sent to any member subsequently, more than two 

 months in arrears. All membership fees shall be clue and payable at 

 the beginning of the year and no subscription, for the benefit of any 

 member or associate, to the organ of the society shall be made by the 

 treasurer, until this annual fee shall have been paid. 



SECTIONS. To facilitate local intercourse by meetings or otherwise, 

 the Society may establish sections for the members of the Atlantic 

 coast, Pacific coast and Mississippi valley (or other) regions. Meet- 

 ings within each sectional area may be arranged by the local sectional 

 vice-president, and the members of the section may elect temporary 

 officers, except the vice-president when present, and by a majority vote 

 assess such local subscriptions as may be needed to carry on local 

 work, in addition to the regular annual fees. 



NOMINATIONS AND ELECTIONS. Owing to the scattered distribution 

 of the membership, voting may be by ballot mailed to the secretary, 

 who shall announce the result through the organ of the Society, in the 

 number next following the limit fixed for counting the vote, but no 

 votes by proxy shall be accepted. 



Nominations for officers may be made by any three members or 

 associates, so as to be announced at least one month before the annual 

 election in the Society's organ. Nominations for membership may be 

 made at any time, but at least one month before they are to be acted upon. 



The secretary, treasurer and members of the executive council shall 

 be active or life members, and shall serve until the election of their 

 successors. Elections shall be annual. The president, vice-presidents, 

 secretary and treasurer shall be ex-officio members of the Council. 

 The term of office for the members of the Council (not ex-officio) 

 shall be three years, but three members shall retire each year, and of 

 the nine members elected to the Council at the first election three shall 

 serve one year, three two years, and three the full term, the individuals 

 to be determined by lot ; after which three members shall be elected 

 annually. 



THE COUNCIL. The Council shall conduct the business of the 

 Society, elect members, control expenditures, audit the treasurer's ac- 

 counts, prescribe the duties of Secretary and Treasurer, make rules or 

 by-laws to carry out the details of the organization of the Society, and 

 shall annually report to the Society at least one month before the an- 

 nual election. All new members or associates shall be elected 

 by a majority vote of the Council, not less than five members consti- 

 tuting a quorum. 



13 




ACTIVE MEMBERS. Active members shall be elected from those per- 

 sons actively engaged in research, the collection, or the study of the 

 Mollusca ; and their qualifications shall be stated in the nomination 

 papers. Associates may be any one of good character interested in the 

 general subject or the study of natural history. Corresponding mem- 

 bers shall be residents of foreign countries. 



OFFICIAL ORGAN. The Council may select a periodical, not issued 

 by the Society, as its official organ, and may from the annual fees pay 

 such subscription for the several members and associates as may be 

 arranged for with the proprietors of such periodical. 



AMENDMENTS TO THE CONSTITUTION AND BY-LAWS. The constitu- 

 tion may be amended by a majority vote of the life and active members 

 at any annual meeting, provided notice of the proposed amendment 

 shall have been given in the official organ at least three months pre- 

 viously. Amendments to the by-laws may be made at any meeting of 

 the Council called for the purpose, at least one month's notice having 

 been given to the members of the Council. 



PERMANENT FUNDS AND EXPENDITURES. The sums paid in by 

 patrons and life members shall be invested and constitute a permanent 

 fund, of which the interest only shrill be available for expenses as 

 directed by the Council. All expenditures must be authorized and all 

 investments approved by a vote of the Council, which shall have the 

 Treasurer's accounts annually audited, the result to be included in the 

 annual report to the Society. 



Loss OF MEMBERSHIP. Any member or associate tw r o months in de- 

 fault in his annual subscription shall be notified by the Secretary, and 

 any member or associate who shall be over one year in arrears shall, 

 ipse facto, lose membership; provided that, on a majority vote of the 

 Council and payment of all arrearages, such member or associate may 

 be reinstated without a formal re-election.
