Dr. Burchell, when speaking of the Bless bock, proposed to 

 call it A. albifrons, as the name Pygarga has been used for both 

 the Springer and the Bless bock ; but it is not certain if he in- 

 tended by Bless bock this or the preceding species. Captain 

 Harris's figure shows the distinction of the two species, and he 

 applies Dr. Burchell's name to the one now described. 



A half-grown specimen of this species, when compared with a 

 similar-sized specimen of D. Pygarga in the same paddock, was 

 darker, with a pale spot between the horns, separated by a dark 

 spot from the white on the face ; the temple was white, with a 

 white spot; the legs had a brown stripe down the outer si,de of 

 the front ; and the throat and rump brown, the latter without 

 any white spot.

Bright golden brown, with several black cross-bands narrow- 

 ing at the end. Outside of the fore- and hind-legs dark brown.
