Of the genus thus characterized there exist two well marked and unquestionably distinct species, the Striped Hyæna, or Hyæna vulgaris of modern zoologists, which there can be no doubt is also the Hyæna of the ancients; and the Hyæna crocuta, or Spotted Hyæna, the Tiger Wolf of the colonists of the Cape of Good Hope. To these may probably be added a third species, which there is good ground for believing to be distinct, and which has lately been described by Dr. Andrew Smith, the superintendant of the South African Museum, under the name of Hyæna villosa: this is also a native of the vicinity of the Cape, and is denominated by the settlers the Strand Wolf, or Strand Jut. With the two latter we have, however, on the present occasion, no concern; the only animal of this genus in the Tower belonging to the striped race, which inhabits the greater part of Asia and of Africa, penetrating in the former as far as India, and extending over all the northern part of the latter continent. It does not appear that the striped and spotted races are ever found to occupy the same ground; but the territorial limits which separate the one from the other have not yet been distinctly ascertained.
The striped Hyæna has for its ground colour a uniform brownish gray, which is somewhat darker above than beneath. On the sides of the body it is marked by several irregular distant transverse blackish stripes or bands, which are more distinct on the lower part. Towards the shoulders and haunches these stripes become oblique, and they are continued in regular transverse lines on the outside of the legs. The front of the neck is completely black, as are also the muzzle and the outsides of the ears; the latter being broad, moderately long, and nearly destitute of hairs, especially on the inside. The hair of the body is long, particularly on the back of the neck and on the spine, where it forms a full and thick mane, which may be said to be continued even upon the tail, the latter organ being furnished with strong tufted hairs of considerable length. The mane and the tail are both marked with blackish spots or stripes variously and irregularly placed. Much variety is indeed to be met with as well in the ground colour of the whole body as in the disposition of the markings, which are extremely different in different individuals.
