THE LLAMA.

Llama Peruviana. Cuv.

In common with the Camels, the Llamas are distinguished from all other Ruminating animals chiefly by the absence of horns, by the structure of their feet, and by their mode of dentition, in all of which these two closely allied groups very nearly correspond with each other. In their general form there is also some similarity; but the latter are much lighter in their proportions, and far more lively and spirited in their motions. They exhibit no traces of the clumsy and unsightly humps which disfigure the backs of the former, and their necks and limbs, of greater comparative length, appear to be far less oppressed by the superincumbent weight of the head[182] and body, which are consequently maintained in a more upright and graceful position. The principal difference in their internal structure consists in the want of that extensive appendage to the first stomach, which renders the Camel so peculiarly valuable in situations where water is with difficulty procured, by enabling him to lay in at once a sufficient stock of that indispensable necessary to supply his wants for many days. But even without this appendage the Llamas are observed to be by no means so much exposed to frequent thirst as the generality of animals, and to drink but rarely and in moderate quantity.

The feet of the Camels and of the Llamas are very different in form from those of all the other Ruminants. They are, it is true, deeply divided, like those of the latter, into two apparent toes; but cannot be said, like them, to part the hoof, for they have no real hoof, and the extremities of their protruded toes are armed only with short, thick, and crooked claws. These toes are in the Camels united posteriorly by a horny process, which is wanting in the Llamas. The teeth of both are nearly similar: they consist of six incisors in the lower jaw and two in the upper; of two canines in each; and of six molars in the upper, and five in the lower, on each side. None of the other Ruminants exhibit the least appearance of cutting teeth in the upper jaw. The nostrils of both consist externally of mere fissures in the skin, which may be opened and closed at pleasure, and which are surrounded by a naked muzzle; and their upper lip is divided into two distinct portions, which are very extensible, and capable of much separate motion.

The species of the group, of which the Llama forms[183] the type, have been involved by the imperfect descriptions of naturalists in almost inextricable confusion. No less than five have been admitted; but the variations of colour and of size, and the degree of length and fineness of the wool, differences rather commercial than natural, afford almost the only positive distinctions that have yet been laid down between them; and when we consider that some of them have been for ages in a state of domestication, it will readily be allowed that such characters as these are, to say the least, trivial and uncertain. Our animals, which are nearly four feet in height at the shoulder, and somewhat more than five feet to the top of the head, have the neck, the back, the sides, and the tail, which is rather short, covered with a beautiful coat of long, bright brown, woolly hair. The long and pointed ears, and the small and attenuated head, on which the hair is short, close, and even, are of a grayish mouse-colour; the outside of the legs is of the same colour with the sides of the body; and their inside, as also the under part of the body and the throat, pure white. The hair on the limbs is short and smooth. In these respects they offer but little to distinguish them from any of the animals which have been exhibited in this country under the various names of Llamas, Pacos, and Guanacos. There is, however, at present in the Garden of the Zoological Society, an animal, which besides being of larger size, covered with longer and coarser wool, and entirely white (which latter circumstance may be purely accidental), differs remarkably in the form of the forehead, which in it is perfectly flat, while in our animals it rises in a strong curve. This character, it is probable, affords a permanent ground of[184] distinction, although we venture not at present to speak decidedly respecting it.

The Llamas congregate together in considerable herds on the sides of the Andes, and generally in the colder and more elevated regions. When the Spaniards first arrived in Peru they were the only beasts of burden employed by the natives; and even at the present day, when horses have become so excessively common, they are usually preferred for passing the mountains, on which their sureness of footing, exceeding even that of the mule, gives them a manifest superiority. Generally speaking they are quiet, docile and timid; but they occasionally exhibit much spitefulness, especially if teased or ill treated. Their mode of evincing this is very peculiar, and consists in darting their saliva through their nostrils with considerable force. Like all the other Ruminants they subsist entirely on vegetables. Those in the Tower Menagerie have a particular fondness for carrots; and if one of these is abstracted from them while they are eating, their anger is immediately roused, and they spit, as it is termed, with the greatest vehemence, covering with their saliva a surface of three or four yards in extent. One of the animals in the cut is represented in the act.
