 from those of the latter animals, having very narrow crowns, without any additional 

 column on the inner side. 



The wildebeests, or, as they are often called, gnus, are ungainly-looking 

 creatures, distinguished by their broad and short heads, in which the ' muzzle is of

 one another by a considerable interval. The neck is furnished with an erect mane

 by a wide space at the base covered with hair. These straight horns persist as the 

 tips of those of the adult, the curved basal portion of the latter being a subsequent 

 development. In very aged bulls the two horns approximate at their bases, so as 

 to form a helmet-shaped mass completely covering the part of the skull, as in 

 the Cape buffalo. 



There are two well-marked species of wildebeest, confined to South and East 

 Africa, both of which are represented in our illustrations. Of these the common,
