The colour of the young is almost exactly the same as the mother's. 

 The skull:

 The skull is, on the whole, broad and short, so that the lower 

 jaw is but a trifle longer than the length of the skull across the zy- 

 gomatic arches. 



The nasalia are comparatively short, and do not extend forwards 

 beyond the anterior point of the intermaxillaria ; behind, each nasale 

 forms an acute angle, so that the suture with the frontalia has the 

 shape of a zig-zag line with two angles, open in front, and one (the 

 central) open to the back. 



The interorbital Space is very concave; the frontal crests con- 

 verge somewhat on the parietalia, without meeting, again diverge, and 

 at the back touch the side margins of the interparietale, without, how- 

 ever, entering inside the margin of this bone. 



The bullae osseae are but slightly inflated. The palate is per- 

 forated by a couple of quite small and round foramina, the diameter 

 of which is about equal to that of the central premolar ; besides these, 

 several punctual foramina are present at the hinder margin of pala- 

 tinum ; the bones are, on the whole, very thin. The foramina incisiva 

 are short. 



The intermaxillare is above somewhat elongated towards the back, 

 and the suture strikes the nasal suture about the middle (as in Ps. 

 herhertensis). 



The lower jaw has no external foramen as an entrance to the 

 dental canal. The teeth are, notwithstanding the short skull, not very 

 close, for both c and ii in the upper jaw are a little isolated ; other- 

 wise there is nothing abnormal in the dentition. 



In the Upper jaw the central pair of incisors are comparatively 

 small, but longer and thicker than the others. Of the other incisors, 

 »3 is the smallest and very slender; i^ has a rather broad crown. 



The canine is a little bigger than i 3 and p^ . Of the premolars 

 p 1 is small and short , about the size of * 3 . ps has only 2 cusps, 

 as the hindermost is not perceptible. The molars are, as in the other 

 PseudocJiiri,
