REPORT ON THE CRUSTACEA AND MOLLUSCA. 



By Walter Faxon. 



Very valuable contributions to the Museum's collection of 

 Mollusca have been received during the past year from the Rev. 

 R. K. Smith and Mr. W. F. Clapp. These gifts include a lot 

 of marine shells from Buzzard's Bay and another from Cape 

 Cod Bay, together with an assemblage of the land and fresh- 

 water Mollusca of the basin of Lake Champlain. Mr. Clapp 

 has also presented a collection of shells secured by him on the 

 west coast of Florida, with fossil shells from the Caloosahatchie 

 River, Fla. 



Mr. Clapp has contrived by ingenious devices, known only to 

 the skillful collector, to secure many species in considerable 

 numbers that have heretofore been deemed excessively rare by 

 collectors, and he has also by persistent labor increased the 

 knowledge of the geographical distribution of many of our native 

 species of Mollusca. 



Other donors whose favors should be acknowledged are Messrs. 

 Thomas Barbour, S. S. Berry, Hiram Bingham, R. T. Jackson, and 

 S. B. Warner.
