ORDER RUMINANTIA. 241 



largest ; the ears are long, straight, cylindrical at the base, 

 dilated in the middle, almost pointed at the summit, white 

 inside, and furnished with additional bristly hairs. A 

 small space at their root covered with very fine hair ; the 

 tail shaped like a brush, and straight ; the legs covered 

 with close short hair; no brushes on the knees. There 

 are inguinal pores, and the hoofs are narrow and pointed ; 

 brownish-black in colour. The hair is one inch and a half 

 long, standing off the skin ; the interior brown, the longer 

 and exterior gray, their intermixture producing on the 

 back and flanks a general cream coloured or pale dun tone. 

 The belly and end of the tail are white ; the forehead, 

 top of the head, anterior face of the fore-legs and some 

 other spots are yellowish ; the hair is feathery in several 

 places on the back and behind the head. The specimen 

 was brought from the Cape of Good Hope. If we except 

 the omission of an obvious muzzle, the apparent superior 

 length of the horns and head, and their basal direction, 

 scarce a difference remains between this and the last 

 species, but what results from a different tone of colour, 

 which, however, might resemble more if the denominations 

 of teints were alike with every describer of colours. It 

 may be asked here if the female of this species or variety 

 can have been mistaken by M. Vaillant for a kind of wild 

 Equus, which he designates as an Isabella Coloured Zebra. 

 As the gallop of the preceding species is said to resemble 

 the action of a horse, the mistake may have occurred 

 when the animal was seen at a distance. 



The Met Rheebock. (A. Villosa.) This species, known 

 at the Cape by the name of Riet Rheebock, or Reed Roe- 

 buck, and noticed by Lichtenstein under the name of A. Ca- 

 preolus, forms the passage from this group towards the 

 next. M. Desmarets describes the female, and we have 

 long possessed drawings of both sexes from the collection 

 of Mr. Burchell, in part, at the British Museum. In their
