PROCEEDINGS OF THE ACADEMY OF 
[Dec. 
Report of the Department of Mollusca. 
The rearrangement of the general collection in exhibition cases has 
been almost completed, table-cases of gastropods having been worked 
over during the year. Considerable time has been given by Mr. 
Vanatta to the determination and description of Hawaiian mollusks 
sent by Mr. D. Thaanum, of Hilo, Hawaii, and to the work of picking 
out and assorting upwards of 500 trays of shells from material gathered 
by the Curator last year in the Florida Keys. Large quantities of 
leaves and forest debris, gathered by Mr. C. B. Moore, have also been 
picked over, and much valuable material, especially of very small 
mollusks, obtained. 
Mr. Y. Hirase has continued to send Japanese and Formosan mater- 
ial; his latest sendings contain Korean mollusks, which hitherto have 
been almost unknown. About 100 new species have been described 
from this source during the year. 
Other valuable accessions are a series of marine shells from the Great 
Barrier Reef, Australia, including cotypes of 19 new species, from 
Charles Hedley. A collection from northeastern Mexico, from A. A. 
Hinkley. A series of Irish slugs from Dr. R. F. Scharff, and many 
smaller accessions from numerous donors. A large part of this material 
has been worked up, and papers published thereon. The time of the 
special Curator has been largely occupied in the preparation of the 
Manual of Conchology, in which the families Oleaciniclce and Ferus- 
sacidce have been described.
