Llamas are called the camels of the New World, and under this common name are included more than one species. They exist in large herds, and are much more sightly than the animals to which they are compared; their backs are straighter, their heads very handsome, and their fleeces are thick and equal. They will carry a load of 150 lbs., and were the only beasts of burthen found among the Peruvians, when these people were conquered by the Spaniards. Their feet differ from those of the camel, but are equally adapted to the soil which they have to traverse; they are formed of two springy toes, each of which has a rough cushion underneath, and a strong, short hoof on the tip, pointed and hooked, like a claw. These take firm hold of the rapid and precipitous ascents and descents, which they encounter in travelling to and from the mines; in which journeys they carry 100 lbs. of metal over the rugged mountain passes, and perform a distance of about twelve miles during the day. At one time 300,000 were employed by the Potosi mines alone. In one respect they imitate camels by lying down, and refusing to stir when they are overloaded, and they never go beyond their usual pace. They spit in the face of their riders when tied up, or made to lie down; which is particularly disagreeable, from the nature of their saliva. The different species are not clearly defined, and we require a more intimate knowledge of them before we can separate them from each other: the domestic animals are certainly Llamas; then there are the Guanacos, which are also called Huanacos. They live on mountains, but frequently pasture in the plains; and when the females do this, the males watch from a more elevated position; and if they see men approaching, neigh something like a horse, to warn them of their danger, then descend into the valley, and drive their charge before them. Besides these two, are the Vicuñas (spelt also Vicunhas), and Vicugnas, who are of a tawny red colour, and live in the bleak, cold parts of mountains, preferring frost and snow. They are remarkably swift and timid, and their wool is very fine and silky. To these must be added the Paco, or Alpaca, and the Taruga, who are larger, and even swifter than the Vicuñas, and wander about singly, among steep and rocky places. M. Frederic Cuvier thinks there are but three species; the Guanaco, which, in a domestic state, is the Llama; the Paco, or Alpaca; and the Vicuña. I am desirous of dwelling thus much upon these divisions, because the readers of South American travels are often much puzzled by the manner in which they are mentioned.
