from the Argentine Republic, two species of Sloth, several spe- 
cies of Ant-eaters and two species of Scaly Ant-eaters or Pan- 
golins, 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 Pichiciago is a very rare burrowing 
animal. The Great Ant-eater lives on white ants, whose dwel- 
ling 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 uppermost specimen is the 
American Manatee, or Sea-cow, a resident of Florida. The lower 
specimen is the Dugong from Australia. 
Case 3. — Hogs and Peccaries. The Peccaries here shown 
go in small herds of eight to ten, and are not as pugnacious as is 
another species found in South America. This case also con- 
tains three interesting species of deer, the Muntjac; the little 
deer, Cervus steerii, the type of its species; and the Sambur 
of India. 
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. 
Hall 20. 
Case 7. — Several species of deer, including the Pronghorn 
or American Antelope. 
Case 8. — Two species of Antelope from British East Africa 
— Lichtenstein’s Hartebeest, and Cooke’s Hartebeest. 
Case 9. — The Sassabye. 
Case 10. — Two species of Gnus, the White-tailed Gnu and 
the White-bearded Gnu. 
Case ii. — Salt’s Dik-dik, Eastern Abyssinia; Kirk’s Dwarf 
Antelope, British East Africa, a very small species of antelope, 
remarkable for its projecting and distensible snout, and for the
