hoofed mammals — game animals from all parts of the world. 
In the north end is a large habitat group of Alaska Moose 
and thence southward are various representatives of the deer 
family, the antelopes, gazelles, wild sheep, goats, and oxen, 
terminating at the south end of the hall with the Bison and 
Musk Ox. 
Hall 15: Mammals-Systematic. — This hall is at the right 
of the main north entrance to the Museum and is entered 
by passing through the north end of Pullman Hall. With 
the exception of those represented in Pullman Hall, it con- 
tains members of the principal groups of mammals of the 
world arranged so far as practicable according to their rela- 
tionships. Beginning with the lower forms, the monotremes 
or egg-laying mammals of Australia and the pouched mam- 
mals or marsupials, it successively shows various groups, as 
the horse family, the tapirs, sea-cows, rodents, cat family, 
dog family, and terminates with the highest mammals, the 
monkeys and manlike apes. 
In the northwest corner of the hall is a large habitat 
group of American beavers. 
Hall 16: American Mammals — Habitat Groups. — Hall 16, 
next on the south from Hall 15, contains ten habitat groups 
of North American large mammals. From east to west, 
these are as follows: Virginia Deer in the four seasons. 
Spring, Summer, Autumn, and Winter; Stone’s Mountain 
Sheep; Polar Bear; Musk Ox; Prongbuck; Sonora Grizzly 
Bear; American Bison. 
Hall 17 : Osteology-Skeletons. — Contains skeletons of the 
principal vertebrates or backboned animals. These include 
fishes, frogs and their relatives, birds, and mammals. At 
the right of the east entrance are the lower forms, fishes, 
etc., and at the left are the higher apes and man. In the 
center toward the west end is the huge skeleton of a right 
whale. 
Hall 18: Fishes, Reptiles, Marine Fauna. — The east half 
of this hall is devoted to fishes and reptiles and the v/est 
half to marine invertebrates. The fishes are arranged in two 
series, one showing representatives of the principal orders 
and families of fishes and another showing habitat groups 
and special collections of Atlantic and Pacific food and game 
fishes and Chicago market fishes. 
The invertebrates include many of the myriad forms of 
life found in the sea, corals, crinoids, sponges, sea urchins, 
star fishes, crustaceans, and many others.
