CONCHOLOGICAL SECTION. 
The growth of the collection of mollusks during the year has been 
satisfactory, although no single large accession has been received. 
A list of those giving specimens will be fouud in connection with 
the Additions to the Museum. The chief gifts in point of extent 
were the series of Japanese mollusks sent by Mr. Y. Hirase, 
Zanzibar species from Sir Charles Eliot, and Carolinian land snails 
from Mr. J. H. Ferriss. The greater portion of the material has 
been studied and the work on a large part of it is embodied in 
papers published in the Proceedings of the Academy. 
The completion of the monograph on Bulimulidse has rendered 
possible the arrangement of that group in the Museum, where two 
double table-cases now contain the exhibition series. The work of 
identifying and monographing the Urocoptidse is in progress. The 
Manual of Conchology has been issued during the year, as hitherto.
