The tarandrus,[1833] too, of the Scythians, changes its colour, but this is the case with none of the animals which are covered with hair, except the lycaon[1834] of India, which is said to have a mane on the neck. But with respect to the thos,[1835] (which is a species of wolf, differing from the common kind in having a larger body and very short legs, leaping with great activity, living by the chase, and never attacking man); it changes its coat, and not its colour, for it is covered with hair in the winter, and goes bare in summer. The tarandrus is of the size of the ox; its head is larger than that of the stag, and not very unlike it; its horns are branched, its hoofs cloven, and its hair as long as that of the bear. Its proper colour, when it thinks proper to return to it, is like that of the ass. Its hide is of such extreme hardness, that it is used for making breast-plates. When it is frightened, this animal reflects the colour of all the trees, shrubs, and flowers, or of the spots in which it is concealed; hence it is that it is so rarely captured. It is wonderful that such various hues should be given to the body, but still more so that it should be given to the hair. CHAP. 53. (35.)—THE PORCUPINE. India and Africa produce the porcupine, the body of which is covered with prickles. It is a species of hedgehog, but the quills of the porcupine are longer, and when it stretches the skin, it discharges them like so many missiles. With these it pierces the mouths of the dogs which are pressing hard upon it, and even sends its darts to some distance further.[1836] It conceals itself during the winter months, which, indeed, is the nature of many animals, and more especially the bear.
