Humming-birds, which occur also in North America, are found in great abundance in the southern continent. The condor is found on the higher slopes throughout the Andes; the os- trich, toucan, and parrot are also characteristic. Among the Mammalia, the ant-eaters and sloths peculiarly characterize the continent. The tapir and peccary are the only representatives of the elephant, rhinoceros, and hippopotamus of the Eastern continents. The lama, puma, and the. prehensile-tailed monkeys are also characteristic of the region. The South American district of fur-bearing animals ex- tends through parts of Chili and the Argentine Republic. The marsh beaver is the principal animal. 353. Asiatic Fauna.—F rom the great mass of land within the tropics, the fauna of Asia, besides its numerous arctic and temperate species, contains a great variety of tropical forms. Taken in connection with Northern Africa, Asia is essentially the region of extensive dry plains and arid tracts. The vegetation through- .

Fore- - plumage abound. most among these are the man-like monkeys, the orang-outang, the elephant, the royal tiger, and others. Fur-bearing animals are also numerous. Among birds, those with bright, gay-colored Reptiles also are repre- sented, though not to such an extent as in South America. When we bear in mind that in Asia, the horse, ass, goat, sheep, camel, swine, elephant, buffalo, and ox are found in great numbers, it will be seen that Asia, the home of primitive man, is also peculiarly the home of domesticated animals ; that is, of the animals which man has trained to labor for him. The Asiatic district of fur-bearing animals includes Si- beria, Kamtchatka, and the basin of the Amoor River in Mantchooria. The following animals are characteristic: the brown bear, badger, weasel, ermine, sable, otter, marten, and many others. The furs of the sable, black fox, otter, and the ermine, are considered the most valuable. 854. African Fauna.—The peculiarities of the northern portion of the continent have been al- ready pointed out in connection with Asia. It is a fact worthy of notice, that the great deserts of the world, like the Sahara, though nearly desti- tute of any vegetation, are able to sustain many of the highest species of animals. Over these tracts are found the lordly lion, the leopard, and the panther, and the numerous ani- mals on which they prey, such as the antelope, the zebra, the quagga, and others. All these possess powers of rapid locomotion, which pe- culiarly fit them for the arid plains over which they roam. In the remaining portions of Africa, the luxu- riant vegetation is capable of sustaining animals of a larger growth. Here occur the largest of the Mammalia, such as the elephant, rhinoceros, and hippopotamus ; here also is found the giraffe, the largest of the ruminantia; man-like monkeys are also characteristic. 355. Australian Fauna.—The more nearly per- fect isolation of Australia than any of the other continents, together with the peculiar distribu- tion of its heat and moisture, causes its fauna and flora to-differ markedly from those of all the other continents. Australia is essentially the home of the marsu- pials. These are both carnivorous and herbivor- ous. The kangaroo is, perhaps, the most cha- racteristic of the marsupials. Large and power- ful animals are entirely absent; in this respect the continent offers a sharp contrast to Africa.
