Sponges. 
Miss Martin has spent some time in continuation of the work 
done last year, but has been principally occupied in verifying the 
measurements of the skeletal threads of the Keratosa and re- 
cording them on the slides. 
Mollusca. 
Good progress has been made by Mr. Henshaw and Miss Mar- 
tin in the work of sorting and arranging the miscellaneous speci- 
mens which had accumulated in this department. 
The New England collection has been enlarged by the addition 
of about fifty species and varieties. 
The arrangement of the exhibition collection of Lamellibranchs 
is nearly completed and will be reported upon next year. 
Mr. E. W. Roper has donated a number of desirable species to 
the New England collection, and a small lot has been received 
from Mr. H. C. Bradlee. 
Crustacea. 
The arrangement of the general collection has been completed 
by Mr. Henshaw, and it is found to contain about 450 species. 
Two-thirds of this number are identified. 
Insects. 
The New England and general collections of Arachnida have 
been sorted into families by Mr. Henshaw assisted by Miss Martin. 
There are about 1,000 lots. 
The general collection of Neuroptera has been identified and 
labelled by Mr. Henshaw. 
The slides of parasitic forms received with the Burnett collec- 
tion have been sorted and in part identified. 
The general collection of Diptera has been sorted into families, 
and the Harris, the New England and general collections of Hy- 
menoptera have been worked out, and about two-thirds of the 
whole identified and labelled by Mr. Henshaw. 
The Harris collection contains quite a number of Thomas Say’s 
types which will be more fully reported upon at some future time. 
Birds. 
Early in the winter Mr. William Brewster resigned the charge 
of this department, in consequence of inability to give the time 
necessary for the care of the collection.
