SIWALIK AND NARBADA CARNIVORA.

broken off in front at tlie anterior border of the orbit. It is of considerable 
importance, since it shows the sutures between the frontals, nasals, and maxillse. 
The nasals {no) terminate superiorly in a broad arch ; reaching to within a very 
short distance of the point to which the nasal process of the maxilla extends ; the 
termination of the latter ( mx ) being likewise blunted, and the intervening frontal 
process very short. 
In the tiger, the extremity of the nasals is pointed, and the nasal process of the 
maxilla, which is blunt, never extends up to the level of the former ; the average 
interval between the two being about lialf-an-inch, and the intervening frontal 
process long and pointed. In the lion, the sharply pointed extremity of the maxilla 
extends up to the level of the equally acute nasal extremity ; the frontal process 
being extremely long and pointed. In the jaguar, the relations of these bones are 
nearly intermediate between the tiger and the lion ; the maxillary process being 
sharper and extending higher up than in the former, but not so far as in the latter. 
In the leopard, Prof. Owen observes 1 that the relation of these bones is the same as 
in the tiger, and this is true of many specimens. In some, however (as in a skull 
from Kashmir in the writer’s possession), the blunt maxillary process extends up to 
the level of the nasals, whose extremity is somewhat rounded ; the descending 
frontal process being comparatively short. This skull comes nearer in this respect 
to the fossil than any other which has come under the writer’s observation. 
The length of the present specimen is eight inches ; or almost exactly equivalent 
to the corresponding part of the larger of the two tigers’ skulls whose dimensions 
are given above. The specimen measures 3-3 inches across the post-orbital processes 
of the frontals : the interval between the hitter and the hinder borders of the 
occipital condyles being 6-4 inches. 
Third cranium. — In figure 2 of plate XL. there is given a lateral view of an 
imperfect cranium of another large Felis in the Siwalik collection of the British 
Museum ; which is the specimen already mentioned as having been provisionally 
named F. grandicristata by Mr. Bose, whose description may be quoted : — 
“ The specimen consists of a cranium deficient in the facial portion in front of 
the orbits. The zygomatic arches, brain-case, and its base are beautifully preserved. 
The skull belonged to an animal considerably larger than F. 
crista ta, and of about the same size as the larger varieties of the royal tiger. The 
sagittal crest (slightly damaged posteriorly) is much thicker and more prominent 
than in F. cristata , and stands vertically on the roof of the cranium. Its height 
anteriorly is six times greater than the corresponding height in , the tiger. The 
ridges which originate from behind the post-orbital processes of the frontals are 
stronger, and run obliquely to a greater distance than in any other large forms of 
Felis ; and these, instead of perfectly blending to form the sagittal crest, run parallel 
nearly as far as the occiput, forming a narrow and shallow groove along the median
