IT. ZOOLOGY.
Arrangements have been made for the construction of a
new case in the south-west corner of the zoilogical gallery.
The entire collection of Birds has been rearranged and
relabelled, so that the visitor can now read both the scientific
and popular names of the species. The labels are supported
by a new device which seens to be very effective.
The rearrangement and relabeling of the land and freshwater univalves has been completed; and the visitor can now
read distinctly the name of each species. Many marine shells
and other specimens have for the first time been arranged and
placed on exiibition. Among these are the last deposite of
shells from the Smithsonian Institution; and the specimens
fiom the coast of Maine, received some years since from Dr.
J. DeLaski. A collection of forty species, (400 specimens) of
duplicate shells-mostly marine-has been brought fioml the
attic, where they had lain since the life-time of Dr. Houghton,
and worked over and packed away. The zoological specimens
of the Foote collection, 40 in number, so far as received, have
been worked up.* The Cicadas have been investigated and
arranged; and the diurnal Lepidoptera further studied and
catalogued.
Mr. Harrington, assisted, to some extent, by T. C. Chamberlain, and Messrs. Mark, Markham and Montrose, has collected the following fiesh specimens: Mammals, 14; Birds,
350; Reptiles, 15; Articulates, 1250; Molluscs, 350; total
1979 specimens. Most of these have been identified and
labeled.
Mrs. S. E. Becraft, a lady of Ann Arbor, has been occupied nearly four months as taxidermist to the University, and
has given good satisfaction. She is still on duty. She has
been principally engaged in renewing the illustration of our
common species of birds and quadrupeds. Something over
200 specimens of birds have been mounted, and numerous
skins preserved for exchanges. Mr. J. Hobson, the taxidermist of the Audubon Club, of Detroit, was employed to mount
a fine panther and a Boa constrictor.
* The Insects reported last year were subsequently taken by Dr. Foote,
and sent to Philadelphia for determination; since which none have been
returned.
