The skins adverted to are those of full grown animals, and they 

 accord very well with the description of the species furnished by Mr. 

 Martin ; but two very conspicuous characteristics of the living animal 

 might pass unnoticed in these skins, namely, the variegation of the face, 

 which is of a leaden- black, contrasting with pinkish flesh-colour on the 

 mouth and lips, extending to the lining of the nostrils, besides which 

 a large semi-circular mark of a paler and more livid tint occupies the 

 inner half of each orbit, — and secondly, a longitudinally disposed erect 

 crest upon the vertex, rising abruptly from amid the rest of the hair of 

 that part, and being analogous to that of the Sumatran 5. cristatus, 

 (Raffles,) with which I should not be surprised to find the present 

 species identical : Raffles, however, says nothing of the variegation of 

 the face, and he remarks that " the young Chingkaus are of a red- 

 dish-fawn colour, forming a singular contrast with the dark colour 

 of the adults," whereas very young examples of the present animal 

 agree in colour with full grown ones ; he also mentions that the 

 under part of the body is merely " paler," while in the Arracan 

 animal this is dull white, and purer white in the young. In adults, 

 the whole hair of the crown is much elongated, the tuft still rising up 

 among the rest; and that forming the whiskers stands far out on 

 each side, forming lateral peaks in addition to the vertical one. Five 

 examples before me (three of which are alive) exhibit scarcely any 

 difference in shade of colour, all being of a ashy dusky-black, darkest 

 on the head and extremities, a good deal silvered on the back, white 

 underneath or in front, and the tail more or less albescent either at base 

 only, or for the basal half or two- thirds, or even the entire tail ; there 

 is little trace of beard, and the shortish scanty hairs growing upon the 

 flesh-coloured lips are white. The young, besides a whining noise, to 

 express their wants, frequently emit a mewing cry that might be 

 mistaken for the mew of a cat. 



To the same group of Semnopitheci belongs my S. pileatus, J. A. S. 

 XII, 174, a species which abounds on the skirts of the Tipperah 

 hills, retiring far into the interior during the rains, (as I am in- 

 formed by F. Skipwith, Esq., Judge and Magistrate of Tipperah, 

 to whom the Society is indebted for some interesting zoological spe- 

 cimens,) and it would appear also to extend sparingly upon the Naga 

 range eastward of Upper Assam. A fine specimen of an old male has
