The arid regions of South America are inhabited by four species of long-necked, long-haired, soft-footed animals, so closely related to the camels of the Old World that they are called _cameloids_. There are four species. The llama and alpaca are in a state of domestication, and are supposed to have been derived from the wild guanaco and vicunia. All of them might almost be described as small-sized, humpless camels; and their tempers and mental traits are as odd as their forms. The ordinary cameloid is a quiet and inoffensive creature; but the exception is a rogue of rogues. It will bite with the persistence of a bull-dog, and with its massive, chisel-like lower incisors inflicts ugly wounds. At times a llama or vicunia becomes actually insane, and seeks to destroy every living creature within its reach. Regardless of punishment, such creatures attack their keepers and their herd-mates, spit upon visitors, and rage up and down their corrals in most absurd fashion. Occasionally such individuals require to be completely isolated. The Llama, (_Lama glama_), is the largest and strongest member of the group. Its body is covered with a thick mass of long, wavy hair of fine texture, which may be either brown, white, white and brown, or almost black. The head and legs are short-haired like those of the guanaco. From time immemorial, this animal has been used as a beast of burden, and in the Andes has played an important part in the mineral industry by carrying silver ore and bullion from the mines. The Alpaca, (_Lama pacos_), is bred for its wool. It is smaller than the llama, but more abundantly haired on the legs, neck and head. Its fleece is long, and lies in stringy tufts. Usually its color is dark brown or black, but occasionally a white Alpaca is seen. A white specimen in the Zoological Park collection has blue eyes. The Guanaco, (_Lama guanacus_), is one of the most interesting and valuable wild animals now found in Patagonia. Unfortunately, it is so stupid and incapable that it is easily killed. The natives of Terra del Fuego, themselves almost the lowest and most ignorant of men, slaughter Guanacos for food by surrounding groups of them and clubbing them to death. In size the Guanaco is between the llama and vicunia, and its shoulder height is about 4 feet. Its hair is thick and woolly, of a pale reddish color, and there are naked patches on the legs. This species is found on the Andes, from Ecuador to Terra del Fuego, and appears to be most abundant in Patagonia. The Vicunia, (_Lama vicunia_), is the only member of the cameloid group which is not clothed with a mass of long hair. It is the smallest member of the group, comparatively short-haired, its color is a uniform light brown, its head is small, and there are no callosities on the hind legs. The Vicunia is found from southern Ecuador, through Peru to central Bolivia. NORTH AMERICAN DEER. Elk, Mule Deer, White-Tail, Caribou and Moose.
