354 CLASS MAMMALIA. 



three feet, and two feet eight inches at the croup ; the fur 

 is of a deep blackish-purple brown ; the ears are asinine, 

 six inches and a half long, abundantly lined with light hair 

 within, and on the edges ; there is a lachrymary sinus 

 beneath the eyes ; the face is straight, and the nostrils sepa- 

 rated by a demi-muzzle; the colour of the face and back 

 of the ears rufous-dun, with a black streak commencing 

 between the horns, contracting between the eyes, then 

 again widening to near the nostrils ; the legs are robust 

 and rufous, with short, stout, and black hoofs; the,tail de- 

 scending to the houghs, is terminated by a tuft of long black 

 hair ; the number of mammae could not be ascertained. 



It is probable that Mr. DanielPs figure, represents a 

 young male. The adult of that sex must of course be larger 

 and the horns still more powerful than those of the female 

 we have described, and probably also more ponderous in 

 its proportions. Mr. Burchell fell in with only this one 

 specimen in the Booshwana country, where the species 

 must be rare, but probably it is more abundant on the 

 desert of the southern Sahara, beyond the Gareep : both 

 this and the Koba may possibly hereafter form a separate 

 section of this, or of the genus Antilope. 



The Boselaphine Group. 

 We circumscribe this group, originally instituted by M. 

 de Blainville, to the single species of Oreas of authors, 

 and to a supposed variety, which deserves the denomination 

 of a species. The Boselaphi are among the highest and 

 most bulky ruminants, and although the horns have a dis- 

 tant resemblance with some of the middle-sized Ante- 

 lopes, their stature and ponderous make, thin heavy dew- 

 lap and elevated shoulders, bring them more properly 

 into the present genus. In this group the horns are 

 common to both sexes, they are heavy, very robust, placed 

 on the summit of the frontals, transversely wrinkled*
