REPORT OF THE CONCHOLOGICAL SECTION. 



The growth of the collection of mollusks during the year has 

 been satisfactory. The total number of accessions, 2,705, although 

 less than in several years, comprises a large amount of material 

 preserved in alcohol aud also more species new to the collection 

 than has'e been added in any year since the A. D. Brown Collec- 

 tion was received. 



The chief accessions are as follows: Over 800 species of Japanese 

 mollusks received from Mr. Y. Hirase, of Kyoto, Japan; a large 

 lot of South Sea shells collected by C. D. Voy in 1872-3, and 

 presented by Mrs. Annie P. Cope; a small series of shells from 

 Hawaii and Torres Strait, sent to our Treasurer, Mr. Roberts, by 

 Mr. D. Thaanum, consisting largely of species new to the collec- 

 tion, aud a second collection from British East Africa from Dr. 

 A. Donaldson Smith. The series of American mollusks has been 

 increased by about 200 species from the Galapagos and Cocos 

 Islands, collected by an expedition from Leland Stanford, Jr. 

 University; a selected series from the Gulf of California from 

 Mr. J. G. Malone, and a small series of C. B. Adams' Panama 

 shells; while Messrs. E. H. Ashmun, A. C. Billups, G. H. Clapp, 

 T. D. A. Cockerell, M. J. Elrod, J. H. Ferriss, Dr. Henry 

 Skinuer, Bi-yant Walker, aud many others have added valuable 

 material to the collection of United States mollusks, both dry and 

 in alcohol. A portion of this material has been worked up by Mr. 

 Vanatta and the Conservator in special papers. 



The Academy purchased 328 species of air-breathing proso- 

 branch snails new to the collection. Progress has been made in the 

 rearrangemcmt of the Pelecypoda and the alcoholic collection.

 revised in the progress of monographs of these groups.
