REPORT ON THE INVERTEBRATA. 
By J. WALTER FEWKES. 
DurRiInG the past year much time has been occupied in the 
examination of the additional collections lately placed under my 
charge. I have especially devoted myself to the Mollusca, and 
have become more familiar with the material in the collection. 
A new collection of wax models, illustrating the embryology 
of common types, has been added to those already on exhibition 
in the gallery of the Synoptic Room. 
As in former years, the Crustacea have been in charge of 
Dr. Faxon, who has put illustrative genera on exhibition in the 
Atlantic and Europeo-Siberian rooms. He has also sent material 
for special research to Prof. A. Giard and to Prof. J. E. V. Boas. 
A series of Mollusks has been added to the Australian Room. 
By far the larger part of my Museum work has been on the 
Atlantic and Pacific Rooms, preparing a varied collection, illus- 
trating these faunz, and a good beginning has been made as far 
as the Sponges, Medusz, Corals, Echinoderms, and Mollusks 
are concerned. 
We have received from Professor Ward, of Rochester, a few 
Australian Bryozoa, and a beautiful new siliceous sponge of the 
genus Rosella, taken in shallow water near MRED California, 
has been added to our collections. 
The types of the Invertebrata under my charge have been 
used by several specialists; one or two special students of the 
University have also consulted them. As in past years, some 
time has been taken up in the identification of specimens brought 
to me for that purpose. 
One or two students have applied for instruction in the depart- 
ment under my charge, and there were several applicants to 
make up a dredging party on the coast of New England, as in 
former years.
