and subsist on roots and grain. The Kangaroos are grass-eat- 
ing animals. The Dasyures are devourers of flesh. All the 
other animals belong to the sub-class Eutheria. 
Case 2. — Contains Edentates, including Armadillos, the 
strangely armored Pichiciago from the Argentine Republic, two 
species of Sloth, several species of Ant-eaters and two species 
of Scaly Ant-eaters or Pangolins, from Africa. The Armadillos 
have most of the skin converted into an armor of bony plates. 
They live on roots, insects, reptiles and carrion. They are able 
to burrow with astonishing rapidity. The Great Ant-eater lives 
on white ants, whose dwelling it tears open with its strong claws. 
The Pangolins have the body covered with overlapping horny 
plates. They subsist on ants. 
This case also contains two representatives of the Sirenia. 
These are aquatic herbivorous animals which, in external form, 
resemble the whales. They have, however, no close relation- 
ship with the latter animals. The left-hand specimen is the 
American Manatee, or Sea-cow, a resident of Florida. The 
right-hand specimen is the Dugong from Australia. 
Case 3. — Hogs and Peccaries. The Peccaries here shown 
go in small herds of eight or ten, and are not as pugnacious as 
is another species found in South America. 
Case 4. — Female Wapiti ; the male of this species is in the 
South Court. 
Case 5. — Reindeer and its close relative, the Caribou, from 
Maine. These are the only deer the females of which have well 
developed horns. 
This case also contains the female Moose. 
Case 6. — The male Moose. 
Case 7. — A large male specimen of Stone’s Caribou from 
Alaska, and several species of small and peculiar Old World 
Deer, including the Musk Deer, Water Deer, Muntjac, Tufted 
Deer and the tiny Mouse Deer.

a Fallow Deer and a Philippine Deer.
