the hairs are most distinct ; and the predominant grey colour of the 

 rump and of the outer side of the thighs may be regarded as a pecu- 

 liarity by which this species is distinguished externally from the 

 other two species. Its size is the same as that of N. saltianus. 

 The skin of the knees of the fore legs is bare of hairs and callous, 

 which I have not observed in any of the specimens of the two other 

 species. 



The cranial characters prove unmistakably the specific distinctness 

 of the Damara-Land specimen. 



1. As in N. saltianus, the intermaxillary and lacrymal bones

 snout is narrower than in N. saltianus, which is especially striking 

 in the lower view of the snout (figs. 9 and 10).

2. iVlso with regard to the form and size of the nasal bones the 

 new species is in some measure intermediate between the two other 

 species. The suture, by which the nasals are united with the
