A large species of a uniformi}' dark colour ahovi; and l)elow. 



Size large, though less than in S. hageni Jent., or 8. nkjripes 

 Thos. Fur soft and thick, mainly composed of the woolly under- 

 fur. Cheeks on each side, just below the posterior canthus of 

 tiie eye, with a small projecting wart bearing three or four 

 stiffish bristles ; aural region with soft hair tufts, although tliese 

 are little prominent owing to the uniformly dark colour of 

 the fur ; ears themselves small, laid forward in a spirit specimen 

 they do not reach to the posterior canthus of the eye; in out- 

 line they are much narrowed above, having a marked concavity 

 at the middle of their outer margins ; their sul)stance naked 

 terminally and internally, but the basal lobe of the outer mar- 

 gins is much thickened and provided w^ith a distinct hair tuft, 

 and the internal base is also tufted. 



Colour of whole animal , above, below, on ears, limbs, para- 

 chute and tail uniform smoky brownish black, nearest to, but 

 darker than, Ridgways " seal-brown „ . The only break to the 

 general uniformity is that some specimens have a certain number 

 of white hairs on the middle line of the chest ; these are pre- 

 sent in the male and at their maximum in the female co-type, 

 in other specimens they are wholly absent. 



Hind-feet short and unusually broad ; their soles hairy for 

 their proximal half-inch, naked terminally, with broad, low, and 

 little defined pads. Tail broad, oval in section and only indistinctly 

 distichous. 



Skull with a narrower form and more elongate muzzle than 

 usual; postorbital processes long and slender; bullae low and flat- 

 tened, just as in S. hageni, not appearing on the back of the skull. 



Cheek-teeth in structure apparently very much as in S. ge- 

 nibarbis, and, to a less extent, in S. hageni; their form ^hort 

 and broad ; p 3 present, oval in section.
