paler, greyish or yellowish, but not conspicuously contrasted. 

 Limbs and upper surface of hind feet smoke-grey." 



" Skull in its general characters like that of A. hottentottus , but 

 markedly narrower across the brain-case ; and the zygomata less 

 thickened at their posterior base. As a result, the two skulls being 

 of about the same length, the general outline was much less broadly 

 triangular. Muzzle and interorbital region narrow and delicate." 

 " Dimensions of the type, measured in the flesh : Head and body, 

 129 mm.; hind foot, 13." 



" Skull: greatest length, 28 ; basal length, 22*6; greatest breadth 

 across brain-case, 16*6; greatest height, 12-6; interorbital breadth, 

 8 ; front of i' to back of m^, 10*5 ; palate, breadth across pre- 

 molars, 8'1." 



"■ An adult female had a head and body length of 118 mm. ; 

 greatest skull length, 25-7." 



While this is undoubtedly a well-marked variety, differing in the 

 almost complete absence of brown, the resemblance to the typical 

 C. hottentota is seen in the lighter cheeks and the occasional 

 presence of the white spot over the eye as seen in C. h. iris, and 

 also in the slight flecking of white above the muzzle. In the shape 

 of the nose pad there is no apparent difference. As regards size, 

 the Knysna form is not smaller than the typical one. In fact, out 

 of a very large series of specimens from Stellenbosch, Grahamstown, 

 and St. John's, I have only seen one with a skull as large as that of 

 the type specimen of G. h. corrice. 25 to 27 mm. is the usual size, 

 exceptional specimens being found both larger and smaller. Thomas 

 states that the skull is " markedly narrower across the brain-case" 

 in G. h. corrice. But while some specimens of the typical 

 G. hottentota are relatively broader, the average relative breadth 

 is almost exactly the same as in Thomas's type. I have measured 

 at random ten skulls of the Stellenbosch form, taking them as they 

 came, and the measurements are these : (1) 1. 26, b. 15*5, (2) 1. 27'5, 

 b. 15-3, (3) 1. 26-2, b. 16-3, (4) 1. 27-7, b. 17, (5) 1. 27-2, b. 16-5, (6) 

 1. 27, b. 15-5, (7) 1. 27-8, b. 16-5, (8) 1. 27, b. 15-6, (9) 1. 26-5, b. 16-5, 

 (10) 1. 28-2, b. 17 ; the average being : length, 27-1 ; breadth, 16-1, 

 which is practically identical with that of Thomas's type, 28 and 

 16'6. As regards the zygomata being less thickened at the base, 

 I cannot observe any difference in the specimens I have examined. 



There are specimens from Knysna in the South African Museum, 

 the Albany Museum, and in the Maritzburg Museum, Natal. One 

 of the specimens in the Natal Museum is particularly interesting 

 from there being a distinct brownish tinge in the fur of both the 

 back and front. The back is very dark sooty brownish black, not
