PROCEEDINGS OF THE ACADEMY OF 
[Dec., 
REPORT OF THE CONCHOLOGIOAL 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 and also more species new to the collection 
than have 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, and 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 
Skinner, Bryant Walker, and 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. 
Yanatta 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 
rearrangement of the Pelecypoda and the alcoholic collection. 
The remainder of the Bulimulidoe and the genus Cerion have been 
revised in the progress of monographs of these groups.
