and becoming " drab gray " towards the flanks ; shoulders in some 

 individuals covered with long creamy white or silvery hairs. Long 

 hairs on flanks pale creamy white or yellowish, in some cases pro- 

 ducing quite a silvery effect, owing chiefly to the glossy nature of 

 the hairs. Whiskers, sides of face and neck pale creamy white. 

 Arms pale greyish liver colour, mixed with white, darkening gradu- 

 ally towards the hands, which are black or very dark brown. The 

 amount of white on the arms is evidently a very variable character ; 

 in one of the skins the entire limbs are creamy white with a brown- 

 ish wash on the hands. The hind limbs are very similar in colour, 

 the tibial portion is usually clothed with rather long white hairs 

 which extend, in some cases, as far as the metatarsal region ; in a 

 pale specimen from Nimar, 0. P., the feet are almost entirely cover- 

 ed with long dirty white hairs, the toes alone being slightly tint- 

 ed wdth brown. Entire undersurface of body creamy white or 

 yellowish ; hair on anterior portion of belly and inner sides of limbs 

 thick and long, remainder of ventral surface sparsely covered with 

 rather short hairs. Beard, in old males, fairly well developed, but 

 never to such a marked extent as it is in P. schistaceus. Tail similar 

 in colour to hind quarters, gradually paling towards the terminal 

 portion ; in some specimens the tail terminates in a creamy white 

 tip, the hairs rather longer towards the tip but not forming a con- 

 spicuous bushy termination. The general appearance of the entellus 

 tail is much slighter than that of schistaceus, where the hairs are all 

 very much longer and of nearly equal length throughout the entire 

 tail, giving it a thick cylindrical appearance. 



As regards the cranial characters we meet with considerable 

 variation in individuals of the same sex and age. As in schistaceus 

 the males possess far heavier and larger skulls than the females, 

 and any comparison between specimens of different sexes is useless 

 for systematic purposes. Before dealing with individual variation 

 it will be of interest to consider the general cranial characters of the 

 true entellus ; the following description is taken from the Bengal 

 skulls already mentioned compared with a skull of schistaceus. 

 Skull fairly large and stoutly built, but not approaching in size 

 that of schistaceus. Anderson* comparing the two skulls writes : — 

 " The skull of S. schistaceus is somewhat larger than that of 

 S. entellus ;" it is obvious that this statement is founded on im- 

 mature material. This new series of skulls shows that the skull 

 of entellus is very much smaller than that of schistaceus, the greatest 

 length of an old male entellus skull is only 130 mm., whereas the 

 same dimension in an old male schistaceus is fully 150 mm. The 

 most striking difference between the two skulls, apart from size, is 

 in the shape of the facial region, schistaceus possessing a very elong-
