CATALOGUE OF THE MOLLUSCA OF GEAND 

 RAPIDS, MICHIGAN. 



BY A. 0. CUEEIER. 



The following list of Mollusca, inhabiting the vicinity of 

 Grand Rapids, Michigan, is offered preparatory to a more ex- 

 tended paper on their local characteristics, etc., and is intended 

 to invite criticism, in view of making it more complete. 



It will be observed that the number of species* of Ano- 

 donta is somewhat large for a territory embracing less than a 

 single county. Michigan abounds in small lakes, but few of 

 which have been explored for Mollnsca. An efibrt is being 

 made the present season, by my friends, J. A. McNiel, Esq., 

 Dr. William H. DeCamp, and myself, to more fully explore 

 these localities within convenient distance — which will probably 

 add — when referred to competent authority, other species to 

 the list. Several new species have been described (this Jour., 

 part 2, 1865,) as the result of somewhat hasty collections at a 

 feio localities, and rich results may be anticipated when the 

 thousands of our small lakes have been fully explored.
