directed forwards, and on the vertex inclines to radiate. The tail has the same pro- 

 portion and characters as the tail of M. arctoides. 



The skull of the type specimen of this supposed species is nearly in the same 

 state as the skulls of those forms of 31. arctoides which have been described as M. 

 melanotus and M. hrunneus, and the skull, if the downward compression and less 

 depth of the face are left out of view, has a strong resemblance to M. arctoides. 

 In the type M. melanotus, the depth through the orbital and supra-nasal margins 

 of the frontals to the palate is 1-80 inch, and in M. rufescens 1-55 inch ; in the speci- 

 men in the British Museum referred to M. hrunneus it is 1"85, while in the adult M. 

 arctoides it is 2-25. The measurements in the table (p. 48) also show that it 

 is a shorter and narrower skull than the skull of the type of M. melanotus ; but 

 still the differences between them in these respects are so slight that were it 

 not for the vertical compression of the skull, and hence the peculiar type of 

 physiognomy of this stump-tailed monkey, I would have hesitated to have regarded 

 it as distinct from M. arctoides, of which it may ultimately prove to be only a more 

 southern race or variety.

Face and ears black. Buttocks, surrounding ischia, flesh-coloured or rosy. 

 General colour of the animal sooty black, paler on the under surface and darker 

 on the head. Tail short and stumpy. 



The face is black, nearly nude, but sparsely covered with short black hairs 

 on the upper lip. The nose is rather flat, and the nostrils slant outwards. The 

 ears are moderately sized and rounded, and only very sparsely covered with short 

 black hairs. On the side of the face the hairs extend inwards along the malar bone 

 and form a moderate whisker tuft. The hair on the cheeks, temporal region, and
