report. 
The Department of Taxidermy has not been obstructed in the 
performance of its work as have the others. The removal of the 
mammals from the lower hall made it requisite that many should 
receive some attention previous to being stored temporarily, and 
172 were thus treated. The Indian Rhinoceros (formerly a special 
attraction in the menagerie of Central Park) is almost ready to 
be placed on exhibition. 
The total number of groups now on exhibition amounts to forty- 
two ; of this number two are mammals and forty are birds. The 
production of these groups has involved an expenditure of nearly 
$21,000, exclusive of the cases, and it can justly be claimed that 
no other museum in the world possesses a similar exhibit equal 
in interest. Two mammal and two bird groups are nearly ready 
for exhibition. After these four groups and the Bison and Moose 
groups are finished, the work of the department will be the mount- 
ing of specimens for the general collection. 
The report of the Entomological Department shows that the 
greater portion of the year has been devoted to the gathering and 
preparation of the material for the " Jesup Collection of Economic 
Entomology," the remainder of the time having been spent in 
making additions to the Study and Exhibition Collections. Thirty- 
six groups have been added during the past year, of which 
number five large and twelve small ones are displayed, while 
forty-four more are nearly completed, among which are included 
six collected during 1889. 
The insect groups above referred to are a feature as yet unat- 
tempted by any other institution, and they have evoked the con- 
stant praise of visitors. A full description of these groups is 
appended in the departmental report. Mrs. S. Lowell Elliot has 
enriched this department by the gift of the fine collection of 
butterflies, moths, etc., gathered by the late Dr. S. L. Elliot. This 
collection contains about 6600 specimens of butterflies and moths, 
and four hundred specimens of wasps, dragonflies and grass- 
hoppers. 
The rooms in use for the library have been in a very confused 
state for a large portion of the year, and are at the present time
