A very beautiful antelope is the Blue buck, or Blauwboc of the Cape colonists. It is a large, bold animal, with horns ringed, and gently curving backwards. Its skin is jet black; and it is this colour reflected through the ashy-grey hair that gives the animal that purplish or blue tint, whence it derives its name. It is found in small troops on the plains north of Kurrichane; and when wounded, or in the rutting season, the males are dangerous creatures. Another similar species, but larger, is the Tah-kaitze, which is plentiful in the country of the Bechuanas. It is so ferocious in its disposition, that the native hunters fear to attack it with the asseghai; but prefer capturing it in pitfalls. The Black buck is a species of similar character and habits; and in Senegal there is one, not unlike the foregoing, known among the French as _vache-brune_, and called by the Mandingoes _white mouth_. The Pallah is another fine species of South African antelope. Its horns are of the lyrate form, and its colour a bright rufous. It is on this account known among the Dutch colonists as the Rooye-boc (Red buck). It runs in small troops, and is found in the country of the Bechuanas, who hunt it for its flesh. The Stein-boc is one of the slenderest and most graceful of antelopes. It lives upon stony plains and in mountain valleys in South Africa-- hence its name of _stein-boc_, or stone buck. It is very swift, and, when at full speed, will often spring over fifteen feet at a single leap. Its flesh is much prized, and on this account it is hunted eagerly by the natives; so that, although one of the swiftest of animals, it is now rare in most parts of the Cape colony. The Grys-boc is a closely allied species, but not so elegantly formed, nor yet so swift. It hides when closely pursued--thrusting its head into a bush, or squatting like a hare in her form. The stein-boc has a similar habit. The Bleek-boc, or Ourebi, is one of those antelopes which have the curious appendages upon the knees called brushes. It is a large animal, and its flesh is eaten by the Kaffirs, in whose country it is chiefly found. A very similar species, called the _gibari_, exists in Northern Africa--Abyssinia--and also on the western coast.
