114 PROCEEDINGS: BOSTON SOCIETY NATURAL HISTORY. 
Mollusca. 
The Curator reluctantly announced in the last annual report the 
enforced absence of Mr. Edward W. Roper, who was obliged to 
leave his work upon this department unfinished on account of his 
continued ill health. This gentleman returned for a short time and 
succeeded in placing the results of his labor in more satisfactory 
condition. He also deposited his collection of shells, and gave a 
considerable part of them to the Society. These will be noticed at 
some future time when they can be incorporated with the Society’s 
collections. The Curator did considerable work on the Pelecvpoda 
in general in preparation of a paper on “ Terminology proposed for 
description of the shell in Pelecypoda,” an abstract of which was 
published in the Proceedings of the American association for the 
advancement of science. He has been also engaged for a consider¬ 
able time upon the study and description of Achatinellidae of the 
islands of the Hawaiian group outside of Oahu, and has done some 
work also upon the Pectenidae. Miss Martin has rearranged and 
completed the preliminary work on the specimens stored in trays 
under the exhibition cases in the Mollusca room, the gallery adjoin¬ 
ing, and the Fish room, and has also done considerable work upon 
odd lots of shells that have never been worked over. Mrs. Boyd 
has done considerable work upon our duplicate shells. Mrs. Flint 
has catalogued a collection of Pectens, containing a number of rare 
species purchased from Mr. Sowerby, and has also unpacked and 
placed in safe condition the residual lots of the Mayo collection 
which still remained unattended to. Miss Boardman has continued 
her work upon the Curator’s collection from Lawlor’s Lake. 
Mammalia. 
Mr. Charles F. Batchelder, as announced in the last annual report, 
having consented to accept the charge of both birds and mammals, 
has worked upon the identification of the smaller species of Mam¬ 
malia, and has superintended the making of some much needed 
cases for storage, and the work of Mr. Clark in restoring a natural 
aspect to the limbs of our largest stuffed elephant. A large case 
has been ordered for the reception of the giraffe and other large 
specimens at present exhibited in the main hall.
