Report of the Department of Mollusca. 



The growth of the collection during the year has been normal, 

 accessions having been received from ninety persons and institu- 

 tions. Considerable collections of local mollusks have been made 

 by Mr. Bayard Long, who also contributed a large and valuable 

 series from the Magdalen and Prince Edwards Islands. A large 

 quantity of Canadian material from Lake Huron was presented 

 by Mr. A. D. Robertson. A good deal of foreign material has 

 come in from the Hawaiian Islands, Mexico, South Africa, etc. 



Twenty new storage cases have been purchased, each holding six- 

 teen large trays, adding almost 1,000 square feet to our storage 

 -pace. 



Work during the year has been chiefly devoted to the study of 

 Hawaiian snails, but considerable time has been spent in working 

 •up material from Florida, the Rocky Mountains, and Mexico. 

 In collaboration with Dr. Amos P. Brown, Eocene mollusks from 

 North Carolina, and Oligocene material from the Canal zone have 

 been studied. Papers have been published or prepared for publi- 

 cation on all of these topics. 



Mr. E. G. Vanatta has assorted and determined a large amount 

 of local and other American material. His work has been seriously 

 retarded by illness. Acknowledgments are due Miss Winchester, 

 artist of the department, for helpful services throughout the year.
