placed under the corresponding genera contained in the table 

 cases. It is proposed tt> appropriately letter the fronts of these 

 drawers, and then unlock them so that they may be opened by the 

 public. The Swift Collection is rich in West Indian shells, and 

 particularly so in terrestrial species: it comprises 7058 trays, con- 

 taining 30,384 specimens. Mr. W. G. Binuey has frequently 

 favored us with specimens of rare American terrestrial mollusks 

 during the year, so as to nearly complete our series of these shells. 

 Dr. W. D. Hartman, of Westchester, who is preparing for publi- 

 cation a revision of the Partulidae, has carefully examined our 

 collection of these perplexing shells, and added a number of spe- 

 cies. We are indebted to Dr. J. J. Brown for a good collection 

 of marine shells from the Bahama Islands, and to Mr. Henry 

 Yendiyes for a fine series of Jamaica Miocene shells. A typical 

 suite of the land shells collected by the late Wm. M. Gabb in, 

 Costa Rica is among the important additions to our Museum dur-? 

 ing the year. A detailed list of donations is annexed to this 

 report. 



The Section is again greatly indebted to Mr. Charles F. Parker 

 for valuable assistance in preparing specimens for exhibition, the 

 whole of the additions to the cabinet during the year having been 

 mounted on tablets, and placed on appropriate paper trays by 

 him. We are also much indebted to Mr. John Ford for preparing 

 sections of shells for the purpose of showing their internal form. 

 It is proposed to exhibit a section of a characteristic form in each 

 genus, and Mr. Ford has kindly undertaken to prepare them 

 for us.
