250 CLASS MAMMALIA. 



the Cape by the accurate Le Sueur, and found the male in 

 Mr. BurchelPs magnificent donation to the British Mu- 

 seum. The animal stands high on the legs for its length, 

 which is only two feet six inches from the nose to the ru- 

 diment of tail. Of all the smaller antelopes, this appears 

 the most elegant in the delicacy of its limbs, and brilliancy 

 of colour. The Vlackte Steenbock resides in pairs on the 

 open plains, along the borders, and beyond the limits of the 

 Cape Colony, and is very rare. 



The Gry shock. (A. Grisea.) This species was first no- 

 ticed by Mr. Forster, and figured in the Banksian collection. 

 It is larger than the last, being nearly three feet long, 

 nineteen inches at the shoulder, and about twenty at the 

 croup ; the head is oval, and shorter than the former, four 

 inches and a half from the nose to the horns, and six inches 

 from the nose to the ears ; the horns are nearly four inches 

 long, round, black, smooth, vertical, sharp, slightly inclin- 

 ing forwards, one inch and a quarter asunder at base, three 

 inches at the tips ; the muzzle is small and black ; a space 

 round the eyes, and the prolongation of the inner canthus 

 forming the lachrymary slit, are black ; the ears, four inches 

 and a quarter long, are wide and open, marked on the in- 

 side with three dark streaks, and rufous on the outside ; 

 round the nose there is a little whitish ; the rest of the 

 head, neck, body, and thighs, is deep chestnut-red, inter- 

 mixed or stippled with single white hairs ; the throat, 

 breast, belly, and inside of the limbs and legs, are rufous ; 

 the tail protrudes little beyond the hair ; the hoofs are 

 small, black, and pointed ; the pasterns short, and the 

 cannon bones, or shanks, long and slender. 



The Grysbock was described by Professor Lichtenstein 

 under the name of A. Melanotis. It inhabits the mountains 

 overgrown with shrubs, and is swift and vigilant. At pre-
