OSTEOLOGY. 



Skull. S. Africa. 



The Brindled Gnu lives to the north of the Black River or 

 Nugariep, and though herds feed almost on its banks, yet it is 

 not known to cross it. It occurs in large herds on the plains 

 north of the Orange River, and when alarmed each herd de- 

 camps in long regular files. The flesh is much sought after. The 

 Bechuana use the skins for their cloaks or mantles. And. Smith.
