THE MOLLUSCAN FAUNA OF WESTERN NEW YORK.* 

 Frank Collins Baker. 



The mollusks enumerated in the following pages were col- 

 lected by the writer while ou his vacation from July 5th to 

 July 29th, 1897. During that time about seventy-five species 

 were obtained, represented by over 1,500 specimens. To 

 make the list of more value the writer has incorporated sev- 

 eral local lists with his own,t and the paper may be con- 

 sidered, therefore, a pretty complete catalogue of the land 

 and fresh water shells of the western part of the State of 

 New York. Species not found by the writer are marked by 

 an asterisk. 



Local lists are seldom accompanied by a list of the exact 

 stations (and also a somewhat detailed description of the 

 same) and the writer believes that the present contribution 

 will be of some value on this account, as great care has been 

 taken in examining and recording every locality. 



The western part of New York is an especially good region 

 for animals of this class ; there are a large number of streams 

 in which the fresh water forms thrive, and moist woodlands

These are all the papers relating to the Mollusca of Western New York, 

 which the writer has been able to find. There are a number of good lists 

 of Mollusca from Eastern New York, besides those of the whole State^, 

 several of them by the veteran collector, Dr. James Lewis.
