REPORT ON MAMMALS AND BIRDS. 
By J. A. ALLEN. 
THESE departments remain nearly as indicated in the last 
Report, there having been comparatively few additions or other 
changes during the last year. 
To the collection of Mammals have been added nineteen 
mounted specimens, three skins, and one mounted and eight 
unmounted skeletons. Of noteworthy pieces are a female go- 
rilla and a black-tailed deer (Cariacus columbianus), the latter 
contributed by Professor Baird; also, a skeleton of a whale. 
The collection of Birds has been increased by the addition 
of sixty-eight mounted specimens (fifty-eight species) and one 
hundred and seven skins (sixty-one species) ; the latter mainly 
to fill deficiencies in the North American collection. There 
have also been added three mounted and three unmounted 
skeletons. The Birds in the Systematic, South American, and 
Australian Rooms have been labelled, and considerable progress 
has been made in the preparation of the systematic or index 
catalogue of the skins.
