THE NAUTILUS. 29 



C. carinata Hinds, as given by M. Cossmann; the type of Am- 

 phissa is corrugala Reeve, not A. versicolor; the type of Mela is 

 dnpontii Kiener, not phiUppmarum Reeve; Fischer's name for 

 Strombina bicanalifera is Bifurdiim, not Bifurdna, as per Coss- 

 mann; Conidea Swainson, 1840, is a synonym of Pyrene Bolten, 

 1798, but its type is Buccinum punctatum Bruguiere, 1789, not 

 Columbetta punctata of Lamarck, Sowerby and others; the type 

 of Anachis H. & A. Adams, 1853, is scalarina Sowerby, which 

 is quite distinct from rugosa Sowerby, cited by Cossman; the 

 type of Atilia is sitffktsa Sowerby, not minor Scacchi; these cor- 

 rections have already been indicated by Mr. Pace, for the most 

 part, and point clearly to the advisability of consulting original 

 sources rather than relying on quotations by other authors. 



FEESHWATEK SHELLS FROM CENTRAL AND WESTERN NEW YORK. 



BY CARLOTTA JOAQUINA MAUKY, PH. D. 



Some years ago the writer made extensive collections of 

 molluscs from the lakes of Central and Western New York. 

 The preliminary determinations of the species were verified by 

 comparisons with specimens in the Say and Lea collections at 

 Philadelphia and Washington ; and doubtful cases were referred 

 to Dr. Pilsbry, Dr. Dall, or Mr. Charles T. Simpson, who kindly 

 passed judgment upon them. Thus every effort was made to 

 make the identifications correct. Large numbers of individuals 

 were obtained to observe the ranges of variation among the 

 different species. 



The writer presented the collection to the Museum of Cornell 

 University where it is on exhibition. 



From many of these lakes the mollusca have never been 

 before recorded, nor have dredgings for deep-water forms been 

 made except ours in Cayuga Lake. 



It is also interesting historically that Say obtained several 

 types from this region. 



The mollusca were found to be most abundant in sheltered 

 coves where the water is shallow and sun-warmed ; and in the 

 inlets and outlets of the lakes.
