The llama tribe (comprehending, besides the llama, the alpaca, vicuna, and others), is peculiar to South America. Its members are found throughout the prolonged cordilleras of the western side of that continent, from Chili to New Granada, dwelling always at considerable heights above the level of the sea. The llama belongs to the same order (Ruminantia) as the camel of the Old World, and supplies some of the uses of that animal as a beast of burden. Prior to the Spanish conquest, the llama was, indeed, the only beast of burden which the natives of South America possessed. The tapir of the same continent (an animal about the size of a small cow, and readily distinguished by the downward bend of its snout) belongs to the order of pachyderms. Two species of tapir, both of them peculiar to that region, inhabit South America: a third species is native to the island of Sumatra, and the adjacent Malay peninsula, in Southeastern Asia. The paca and cutia (or agouti) both of a family which is peculiar to South America, take the place of the hare and rabbit of the Old World, and belong, like those animals, to the order of rodents. Both are used as food. The capybara and the common guinea-pig belong to the same order. The chinchilla, another of the South American rodents, valued for its delicate fur, is confined to the southern portions of the Andes. The sloth, ant-eater, and armadillo (all belonging to the order of Edentata), are natives of South America. Monkeys are exceedingly numerous all over that continent, especially in the forests of Brazil. These, however, are different in species from the monkeys of the Eastern Hemisphere; they are of smaller size, and (with the exception of one nearly tailless species, found within the forests of the Upper Amazons, within a very limited area) all possess tails, mostly prehensile. None of the apes of the New World makes the same approach to the human form which is found either in the chimpanzee and gorilla of Western Africa or the orang of Southeastern Asia. Toward the close of the day the howling monkeys of Brazil make the woods resound with the most frightful cries; but they are neither of large size nor of formidable powers. The family of lemurs, so abundant in the eastern half of the globe, has not a single representative in the New World. The marmosets, a family confined to America, are numerous within the regions of the lower Amazons. Bats are very numerous in South America--more so than in any other part of the world: among them is the large vampire-bat, to which popular rumor has assigned the most bloodthirsty propensities, though it is in reality perfectly harmless, feeding chiefly upon fruits, with a few insects. All the American bats differ in species from those of the eastern continent.
