﻿E. LÖNNBERG, TWO APPx\RENTLY NEW ANTELOPES. 



The preorbital portion of tlie skull is comparatively mucli 

 longer in the new species tlian in Rh. guenthcri. This is 

 proved by the following comparison. In Rh. gue7itheri tlie 

 distance between the gnathion and the anterior brim of the 

 orbit is equal to the distance from the latter place to anterior 

 margin of meatus auditorius ac- 

 cording to Thomas' figure (1. c. 

 p. 324). But in the new species 

 the former measurement is equal 

 to the distance from the anterior 

 brim of the orbit to the squamoso- 

 occipital suture. 



The general colour of the new 

 species is grizzled grey. This co- 

 lour is produced in the following 

 way. The hair on the neck is 

 dark greyish brown with dirty 

 whitish subterminal rings. This 

 colour extends all över the neck 

 to the withers and down över the 

 shoulders. Along the back the 

 colour has a somewhat sandy 

 tinge because the subterminal 

 rings of the hair are påle sandy 

 yellowish and the tips dark 

 brown. Över the flanks the yel- 

 lowish tinge becomes stronger be- 

 cause the hair of those parts is 

 grey with broad subterminal rings 

 which beginning with påle ochre 

 yellow fade to whitish towards 

 the short brown tip. Towards 

 the belly the white becomes more 

 conspicuous or dominant and the 

 brown tips disappear. The colour Fig- -• 'i'<3p- view of skull of iihyn-

The general colour of the preocular portion of the face 

 and the proboscis is påle rufous, becoming paler almost sandy 

 towards the lips but bright rufous towards the forehead in 

 a zone between the face glands. This rufous colour extends
