Hather rich dark ferruginous above, yellowish below, with a wash of pale fer- 

 ruginous. Tail not concolorous with the body, but greyish. Shoulder streak more 

 or less rufous. Eur rather short, 0*62 inch in length, the basal portion 0*20 inch, 

 blackish, succeeded by an orange-red, a black, and an orange-red and black band, 

 the last being terminal. The longest hairs do not exceed 0-70 in length ; they are 

 banded the same as the other hairs, but the black terminal band is broad. The tail 

 hairs average 0*80, and are banded, either very pale grey, black, grey and black, or 

 black, grey-black, grey and black. The short adpressed hairs on the under surface 

 are marked in the same way. 



The snout is longer than in T. helangeri, and the species is larger.^ 



The young are even more brightly ferruginous than the adults, and have the tail 

 nearly as dark as the body. 



The teeth are larger than in T. helcmgeri, broader, more elongated, and pointed. 

 The 2nd upper premolar has a distinct process on its anterior margin near the base, 

 as in T. ellioti, and a longer pointed internal process. The internal lobe of the 3rd 

 premolar has a well-marked, second, sharp -pointed fang, like, but much smaller than, 

 the lobe itself, at the base of its posterior margin. This process in T. belangeri is 

 indicated merely by an eminence on the posterior margin of the internal lobe. In 

 the lower jaw the canine is not so erect as in T. belangeri, being directed more for- 

 wards, and the anterior and posterior lobes of the 3rd premolar are more strongly 

 developed than in that species. 



The more elongated character of the snout is seen in the skull, the facial 

 portion of wliich is more pointed and longer than in T. belangeri, and is hardly 

 perceptibly arched downwards towards the tip. The nasals, too, are slightly broader, 

 and the skull is considerably longer ; the pre-orbital foramen is not so far removed 

 from the eye, and the malar perforation is larger than in T. belangeri. On a line 

 with the posterior region of the palate and at the posterior angle of the zygomatic 

 arch T. ferruginea is not so broad as T. belangeri ; the orbito-parietal ridge is 

 but slightly or not at all developed in five skulls of this species before me; four, 

 however, have not yet gained their permanent dentition, although but little below 

 the size of the adult.

^ As the specimens before me are all prepared and mounted, I hesitate to give an}' measurements.
