[SMITHSONIAN MISCELLANEOUS COLLECTIONS.] 



CHECK LIST 



SHELLS OF NORTH AMERICA 



FLUYIATILE GASTEROPODA. 



W. G. BINNEY. 



The species whose range is confined to Eastern North America are not 

 indicated by any peculiar marls. The letter W. distinguishes those confined 

 to the Pacific coast ; the letters W. E. are affixed to the names of those 

 found in both the Eastern and Western sections, while the Greenland and 

 Mexican species are also respectively designated by the letters G. and M. 



This list has been compiled from all American publications and the few 

 European monographs treating of this branch of the Mollusca. I have 

 preferred giving the name of many doubtful species rather than omit that 

 of any which my own limited knowledge of the subject does not lead me 

 to consider a synonym. The list, therefore, is not offered as a complete 

 elimination of the synonymy, but rather as a temporary guide to the 

 arrangement of this portion of the collection. It should not be quoted as 

 authority.
