the same, but the collections of special homologies of the limbs and 
systems of organs, etc., among Vertebrates, now occupy room F. 
Dr. W. F. Whitney has entirely rearranged these last and also 
assisted in other parts of the work. 
The collection of Paleontology, which was fully reported on last 
year, has received a small but notable accession in the shape of a 
few very fine specimens of Crinoids purchased by the Laboratory 
Fund. 
Mr. Van Vleck, assisted by Miss Washburn, has arranged and 
mounted the Corals and the Echinoderms. 
The labelling and cataloguing of the Mollusca has been com- 
pleted by Mr. Van Vleck, 'assisted by Miss Washburn. 
A notable addition to this collection has been made in the 
purchase of the Blaschka Models. These are made of glass and 
represent very closely the living animal. There are 74 specimens 
in all, representing 17 genera and 44 species of the soft-bodied 
Cephalopoda and naked Gasteropoda. These have been mounted, 
catalogued, and labelled by Miss Washburn. The entire collection 
of Mollusca can now be reported upon as finished, in so far as all 
but a few families of minute forms were' named by Dr. Carpenter, 
and all of these have been mounted, labelled, and catalogued. 
700 genera, 5500 species, and 35,000 specimens. 
Of these there are on exhibition, 650 genera, and 2600 species 
in the systematic collection, and in the New England collection 
about 125 species. The Pratt collection numbers about 8780 spec- 
imens and the Binney collection, 5920. The mode of exhibi- 
tion of the types and other matters of interest has been so often 
treated of in these reports that it is unnecessary to repeat any 
remarks on this subject. Mr. Henshaw has devoted some of his 
time to the work of rearranging the duplicates. 
The specimens for the formation of the Synoptical collection of 
Insects have been picked out by Mr. Henshaw and progress has 
been made by him in the work of identifying and arranging the 
species of the general systematic collection. 
The collection of fishes has been worked over by Mr. Van 
Vleck. The identification and labelling of the New England col- 
lection of fishes has also been begun by the same assistants. Quite 
a number of species were added by the collections made at Anni
