Llama Peruviana. Cuv.

In common with the Camels, the Llamas are distinguished¹ from all other Ruminating² 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 allied³ groups very nearly correspond with each other. In their general form there is also some similarity; but the latter are much lighter⁴ 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 graceful⁵ position. The principal difference in their internal structure consists in the want of that extensive appendage⁶ to the first stomach, which renders the Camel so peculiarly valuable in situations where water is with difficulty procured⁸, 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 hoof⁹, for they have no real hoof, and the extremities¹⁰ of their protruded
