﻿E. LÖNNBERG, TWO APPARENTLY NEW ANTELOPES. 3 



markable for its very short nasals whioli only measure 12 

 mm. in length while their combined breadth amounts to 14. 

 As is seen from the following table of cranial measurements 

 in which the measurements of Rhy7ichotragus guentheri and 

 its subspecies hindei are quoted from Thomas (Proc. Zool. 

 Soc. resp. 1894 p. 326 and 1900 p. 804) the dimensions of 

 the nasals of the new species are smaller than in the two 

 others. In this respect the new species offers some likeness 

 with Rh. kirki although in the latter, as is already mentioned,

these bones reach forward so far that their anterior ends are 

 level with the front edge of the anterior premolar and there- 

 fore every further comparison between kirki and the new 

 species is unnecessary. 



Thomas' cranial measurements of Rh. guentheri are taken 

 from a female, and the females are according to the author 

 just quoted »rather larger than the males». The measure- 

 ments of Rh. g. smithi are of a male and thus directly com- 

 parable with those of the present specimen. It is evident 

 from such a comparison that Rh. g. smithi is a considerably 

 larger animal with its basicranial length about 7 7o greater 

 than that of the new species. But in spite of this the latter 

 has a, not only comparatively but even absolutely, broader 

 forehead so that the least interorbital breadth on the frontals
