somewhat damaged condition, having a large portion of the 

 parieto-fi'ontal region cut away, and also lacking the nasal and 

 premaxillary bones ; it still, however, serves as a basis of com- 

 pai-ison between the present species and iV. bubcdinus. The third 

 and fourth milk-molars are still retained, the second premolar is 

 just piercing the gum, and the third molar has its summits 

 slightly abraded by wear. The animal may therefore be con- 

 sidei-ecl to have been sub-adult at the time of its death, and may 

 perhaps have not quite attained its full stature. 



As it is, the skull is fully as large as that of an aged individual 

 •of JV. bti,hali?ius, but appears to have been of a relatively broader, 

 deeper, and shorter type, although from its impei'fection I cannot 

 be sure on all these points. The palate is, however, evidently 

 wider, the interval between the bases of the second molar being 

 about a quarter of an inch more than in the Himalayan species. 

 The basioccipital and basisphenoidal rostrum is also markedly widei'" 

 and more tapering, with less prominence of the anterior tubercles 

 for muscular attachment, which are, however, much larger. 



Perhaps the most important distinctive feature of the skull of 

 the white-maned species is the much greater backward extent of 

 the nasals on to the frontal region, in consequence of which the 

 fronto-nasal suture is situated only a short distance in front of the 

 vertical line formed by the anterior border of the orbit, instead 

 of very considerably in advance of the same. The pit for the 

 face-gland also occupies nearly the whole extent of the lachrymal 

 bone, instead of leaving a large flat surface along the upper 

 border of the same. The palatine bones likewise extend much 

 fuither forward on the palate, so that the palato- maxillary 

 foramina are situated on the line of the hinder lobe of the first 

 molar instead of opposite the cleft between the two lobes of the 

 second tooth of the same sei-ies.
