 others. The Association has enough of trained specialists to answer 

 almost any questions relating to conchology. 



The collection of American shells being made by the members of 

 the Association is already a wonderful success. The Academy of 

 Natural Sciences of Philadelphia has given us every facility for 

 caring for the specimens and there are already eight large nmseum 

 cases almost filled by specimens sent by the members. There are 

 about 1000 species already mounted and labelled and the specimens 

 in most instances are superb, the senders generally taking a pride 

 in sending only the finest shells that can-be obained. The placing 

 of fossil species along with the recent ones adds especial value to 

 the collection and makes it, so far as we know, the only zoological 

 collection of the mollusca in America. It is already one of the 

 finest special exhibits of natural history in America, and with the 

 continued zeal and enthusiasm of the members, it is certain to be 

 in a few years, the finest special exhibit in the world. 



In sending shells for the collection, members should bear in mind. 

 1st. That none but members of the Association can contribute spec- 

 imens. 2nd. None but fine specimens from definite localities will 

 be accepted. 3rd. The exhibit is kept separate and apart from the 

 general collection of the Academy of Natural Sciences. 4th, 

 Every species is labelled with the name and locality of the shells, 

 the name and exact address of the member sending it and the date 

 when it is placed in the collection. 5th. Send all sjiecimens 

 intended for the collection addressed to the president of the Associ- 

 ation, care of Academy of Natural Sciences, 19th and Race Sts.,
