50 CATALOGUE OF UNGULATES 



directed at first either forwards and downwards or outwards, 

 with the tips pointing upwards or upwards and inwards. 

 No inguinal glands ; glands in fore-feet only. Skull broad 

 and heavy, with lower extremities of premaxillse expanded ; 

 usually two pairs of premolars. 



The genus, which is restricted to southern and eastern 

 Africa, is represented by two very distinct types, which 

 might well be accorded generic rank if they each included 

 two or more well-marked species. They may be distin- 

 guished as follows : 



A. Horns directed at first forwards and down- 



wards ; back nearly straight ; tail white ; 

 14 dorsal vertebrae ; nasals of median 

 length Connochcetes gnu. 



B. Horns directed at first outwards ; back 



higher at withers than at croup ; tail 

 black ; 13 dorsal vertebrae ; nasals elon- 

 gated Connochcetes taurinus. 



From a prehistoric deposit at Haagenstad, 30 miles north 

 of Bloemfontein, Broom has described (Ann. S. African 

 Mus., vol. xii, p. 14) an imperfect frontlet of an extinct gnu 

 (C. antiquus), stated to be intermediate between that of C. 

 gnu and that of G. taurinus. There is a prominent backward 

 process at the base of the horn-core, as in G. gnu, but the 

 horn-core itself curves more outwards than in that species, 

 and further on is less abruptly bent upwards and backwards.
