1906.] MAMMALS OF KNYSXA, CAPE COLOI>rY. 167 



much darker. General colour of upper surface and sides dark 

 slaty grey, the hairs dark slaty with fine brown tips, the whole 

 most nearly matching Ridgway's " slate-colour " or i-ather darker ; 

 but the crown and a large area on the centre of the back are even 

 darker still, the tips of the hairs being here quite black. The 

 latter dark area extends backwards to the root of the tail. Colour 

 of sides passing gradually into the dull slaty of the belly, which is 

 near " slate-grey," the tips of the hairs dull huffy. 



Skull apparently rather narrower and more lightly built than 

 in specimens of hotientottus of corresponding age, bu.t the age- 

 question is in each case so difficult to settle that larger series will 

 be necessary before a definite statement can be made on the 

 subject. Incisors rather heavy in proportion to the skull.

 Original number 1068. Collected 2 April, 1905. 



This mole -coloured Georychus is no doubt the Knysna 

 representative of G. hottentottus, darker than its allies elsewhere, 

 as is usually the case with animals from forest-regions. 



Mr. Grant's beautiful skins of this and other Georychi biing 

 out clearly that the crown and doi'sal area are generally darker 

 than the rest of the body, a distinct lighter band, coloured like 

 the sides, passing across the back at the shoidders, and sej)arating 

 from each other the darker crown and dorsal patches.

" Fairly common on the open veldt, wherever the hill sides are 

 more or less stony. A fair number were observed, but mostly iu 

 the thick patches of scrub, where it is impossible t-o shoot them."—
