large, oval with a thin covering of grey hairs ; extremities greyish 

 white, claws almost concealed by the long hairs ; the proximal tarsal 

 pad much elongated ; tail slightly shorter than the head and body, 

 dark brown above and below, rings very fine, about 50 to the inch, 

 bristles short, tail-tip in the two specimens examined white ; mammae 

 probably 3 pairs, i.e., 1-2 = 6. 



Skull with the incisive foramina barely reaching the anterior level 

 of the molars ; the front edge of the perpendicular plate of the 

 antorbital foramen with a backwardly directed slope, so that its top 

 angle is somewhat acute. 



The above account is drawn up from a specimen in the South 

 African Museum agreeing very well with the original description of 

 Sundevall. 



Dimensions (from a skin). Head and body 5*5 ; tail 5 - ; hind foot 

 90; from ear-opening to nose-tip 1-10; skull too imperfect for 

 measurement. 



Distribution. The type collected by Wahlberg, now in the Stock- 

 holm Museum, is described as coming from the interior of Kaffirland ; 

 the example in the South African Museum is from Pondoland in the 

 extreme east of the Colony ; no other localities are recorded.

Description. General colour above rich brown, rather darker along 

 the middle of the back owing to the greater admixture of black-tipped 

 hairs, becoming paler on the sides and pure white below, without 

 slaty bases, fur of the upper surface very long and soft ; tip of 

 the nose not white, a dark spot in front of the eye ; ears rather 

 large, about half an inch in length ; hands and feet somewhat slender, 

 both covered with white hairs ; proximal tarsal pad elongated ; tail 

 much longer than the head and body, bi-coloured chiefly owing to 

 the bristles being black above and white below, rings fine though 

 conspicuous, about 46 to the inch, bristles towards the tip of the tail
