slenderer than the other Goat Antelopes; skull without any sub- 

 orbital depression, but with a lengthened fissure ; grinders without 

 supplemental lobes, cutting-teeth equal-sized and shelving. 



I. Antilocapra Americana. The Cabrit or Pronghorn. 

 Pale fulvous ; upper part of rump white. 



Antilope Americana, Ord, 1815. — A. furcifer, A. palmata, H.

 Rafin. — Antilocapra Americana, Ord; Gray, K. M. 19. 



Inhabits N. America; in the plains in summer and in the moun- 

 tains in winter. Called the Goat. Mexico {Coulter). Brit. Mus. 



Dr. Coulter brought a head from Mexico which had the face dark 

 brown, and the horns large, wide-spreading and much hooked at the 

 tip, like the A. palmata of H. Smith (Proc. Zool. Soc. 1826, 121). 

 This is probably only a larger variety in the summer fur. 



II. The Antelopes of the Desert. Nostrils bearded within 

 beneath, operculated, far apart ; horns on the frontal ridge ; nose sub- 

 cervine, with a small muffle ; legs rather stout ; tail elongate ; hoofs 

 rather large. 



4. The Equine Antelopes have a very depressed, spongy and 

 bristly muzzle. 



28. Catoblepas, Gray ; Connochcetes, Licht. ; Bos, Forster. 



Horns bent down on the sides, recurved at the tip ; nose very 

 broad, dilated, spongy, bristly ; nostrils operculated ; tail elongate, 

 bushy, hairy from the base ; hoofs compressed in front ; teats 

 four. 



This genus has been placed with the Oxen by Forster, and in the 

 Bovine group of genera by Sundevall, but it has all the characters of 

 the true Antelopes in the proportion of its leg-bone. 



* Nose with a crest of reversed hair ; chest maned. Catoblepas. 

 1. Catoblepas Gnu. The Gnu or Kokoon. 



Nose with a tuft of reversed hair; chest maned. Brown or 

 blackish ; the lower part of the mane and tail often paler or white. 

 Young : pale fulvous ; nasal, gular, and nuchal mane black.

Inhabits S. Africa. Brit. Mus. 



The A. Gnu of Burchell, H. Smith, F. Cuvier and Harris, " and 

 the Kokong of Lichtenstein," has a white tail and mane. Burchell 

 and H. Smith have given the name of A. taurina to the specimens, 

 which have those parts black. When young they are fulvous, and
