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 considered 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 X. bubalinus, but appears to have been of a relatively broader, deeper, and shorter type, although from its imperfection 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 wider 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 further 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 series.
