Description. Much smaller than (Jr. capensis; general colour dark 

 slaty with a tinge of dark brown above owing to the brown tipping 

 of the slaty fur, below the tipping is dirty white, giving a paler 

 general aspect to the fur ; no sign of white anywhere on the head, 

 which is the same colour as the body ; not entirely blind as described 

 by Brants, but with very small eyeballs about '08 in. in diameter 

 and a distinct slit measuring about the same length ; limbs and tail 

 as in the other species, but with the sole of the foot narrower and 

 more slender. 



Skull with the premaxillae extending further back than the nasals 

 and forming a suture in the middle line behind; the lachrymal bone 

 forms on either side a slight overhanging projection, rendering the 

 skull at this point much wider than it is just behind ; antorbital 

 opening elongated and upright. The upper molars are more rounded 

 than in G. capensis, and decrease in size from in front backwards, 

 the premolar being the largest. 



Dimensions (of a male in the flesh). Head and body 5'62 ; tail 

 50; hind foot '92; skull length 1*35; breadth '97; upper molars - 25. 



Distribution. This is the common Mole Eat of the eastern 

 province of the Colony and Natal, though extending as far as 

 Stellenbosch in the west, whence the South African Museum pos- 

 sesses examples ; other localities are Uitenhage (Smith), Knysna 

 (Victoria), Kalahari (Noak), Johannesberg, Grahamstown, Howick, 

 and Durban in Natal (South African Museum). 



GEORYCHUS NIMRODI, SELOUS'S MOLE EAT. 

 Gcorychus nimrodi, DE WINTON, Proc. Zool. Soc., p. 808 (1896). 



Description. About the same size as G. hottentotus; general 

 colour dark drab with no white spot on the head ; skull with the 

 premaxillae not extending posteriorly bsyond the nasals, so that tho 

 suture between these and the frontals is a simple bowed line ; ant- 

 orbital foramina small, with the outer wall thickened.
