This species appears to be peculiar to Southern Africa. In its wild state it is equally ferocious in its temper and disgusting in its habits with the common species of the North; but it has been found, as we have before mentioned, to be capable of domestication, and of rendering services to man equal to those which he derives from the dog. The pair which have just arrived in the Tower have been placed by Mr. Cops in one den with the Striped Hyæna and with the Hyæna-Dog; and this juxta-position affords an excellent opportunity for a comparison of their characters and disposition. They agree together tolerably well; but the new-comers are hardly as yet reconciled to their abode, and consequently appear shy and reserved. The Hyæna-Dog is the most lively of the group; and his playfulness appears occasionally to give no little annoyance to the Striped Hyæna, who generally returns his solicitations with a surly snarl, but does not seem disposed to resent them farther.

The generic characters of this well known group, comprehending not only the various races of the Dog, the Wolf, and the Jackal, but also the numerous species of Foxes, which differ from the rest only in the form of the pupils of their eyes (which are round in the former, and transversely linear in the latter) may be shortly enumerated as follows. They are all furnished in the upper jaw with six sharp incisors and two canine teeth in front, and with six molars on each side; the same number of each description is also to be found in the lower, with the addition of a seventh grinder. Their tongue is perfectly smooth, the papillæ which cover it being soft and velvety to the touch, instead of rough and pointed as in the Hyænas and Cats. They have five toes to each of the fore feet, of which only the four outermost touch the ground, the fifth being always more or less elevated. On the hind feet the number of the toes is no more than four, for although the rudiment of a fifth is distinctly visible in the skeleton, it is rarely observable in the living animal. On these toes they constantly support themselves in walking, the soles of their feet, or rather that part of the legs which corresponds to the soles of plantigrade animals, never being applied to the surface of the ground on which they tread. Their claws are blunt, strong, but little curved, and not at all retractile; and their use is evidently limited to turning up the earth. Their muzzle is more or less elongated to afford space for the ample series of lateral teeth; and the strength of their jaws, as well as the extent of opening between them, is by this means much diminished. In most of these particulars they exhibit a striking contrast with the more perfect of the carnivorous races, and afford grounds for expecting an equally manifest falling off from their ferocious and sanguinary propensities. The dogs are in fact by no
