brown. On the lips, cheeks, and above the snout the hair is yellow, 

 with a few pale brown hairs interspersed. The reddish-brown hairs 

 begin on what is the interorbital region. Light brown hairs are 

 found on both fore and hind legs. 



The front foot is rather narrower than usual, and only the 2nd and 

 3rd claws are well developed. The lengths of the claws are : 1st, 

 1-5; 2nd, 4; 3rd, 9-5; 4th, -8. 



The skull in shape closely resembles that of C. hottentota and in 

 size agrees fairly well with some of the smaller varieties of the same 

 group, and like the members of this group the lower large molariform 

 teeth have a well-developed posterior talon, but it differs from them 

 all in having 40 teeth. 



The following are the principal measurements of the type skull 

 and of a second specimen in which the skull is damaged :— •

In C. sclateri the teeth bear much resemblance to those of C. 

 hottentota. The second molar is a small tooth, smaller even than 

 the corresponding tooth in C. hottentota, while the third molar is 

 rudimentary. As the only point of difference of any importance 

 between the skulls of C. hottentota and C. sclateri other than size is 

 the presence in the latter of the rudimentary m^ it seems that there 

 is no sufficient justification for separating those species with only 9 

 teeth from those with 10 and placing them in a new genus Aiiibly- 

 somus, more especially as variations in the teeth occur even in the 

 same species. Already I have referred to one mandible of C. granti' 

 having a tooth less on one side than the other, and I have an adult 

 skull of one large Stellenbosch mole, C. hottentota, with only 8 teeth 

 in each upper jaw and 9 in each lower, making only 34 in all. 

 Another specimen from Pondoland has 9 on one side above and only 

 8 on the other, or 35 in all. 



In the type specimen, which is a female, the head and body 

 measure 96 mm., and the hind foot 11 mm. 



The type specimen belongs to the South African Museum (No. 

 3448). 



I have named the species after Mr. W. L. Sclater, the late 

 Director of the Museum, who devoted much time to the study of 

 South African mammals and birds. 



A specimen from the Nieuweveld, 20 miles north from Beaufort 

 "West, differs in colour somewhat from the Beaufort West specimens.
