140 ON THF'-rOSSIL TIGER 



It The frontal is cc^^^sfderably shorter than in the Tiger of the same 

 size No. 3, and>it)ader; so that it has more squareness of form, at the same 

 time that^the ridges stretching from the post-orbitary processes by their 

 proprfi^ence and greater convexity inwards, give it an appearance of more 

 sharpness to the rear. These processes are more obtuse and less salient 

 than in the Tiger, and the outline of the frontal portion of the orbit is less 

 curved. The separate halves of the bone are convex across leaving a deep 

 longitudinal hollow between. 



The parietals are longer than in the Tiger. They are sunk towards 

 their commissure, giving greater appearance of saliency to the sagittal 

 crest. They bulge out, at their junction with the temporals in conjunction 

 with these bones. The sagittal crest, as noticed above, from its great pro- 

 minence, is one of the most distinctive characters about the fossil. It is 

 nearly twice as much raised, as in the largest sized Tiger. Its anterior 

 extremity for a short way divides in two, from running in continuity with 

 the post-orbitary ridges of the frontal. 



The occipital is large in all its dimensions. It greatly exceeds that of 

 the Tiger of the same size in height, and equals that of the large Tiger 

 No. 2. Its margins expand greatly, laterally, in conjunction with the ridge, 

 ascending from the petrous portion of the temporal bones. 

 ^' The temporal on the right side is mostly concealed by stony matrix. 

 On the left it is broken at the zygomatic process. The petrous is compar- 

 atively larger than in the Tiger. The zygomatic arch is elevated and its 

 lower margin is arched more decidedly than in the Tiger. (In this respect 

 it resembles the " Black Jaguar."*) The posterior angle is more acute. 



The corresponding process of the malar differs chiefly from that of the 

 Tiger in the post-orbitary apophysis being blunt and very slightly prominent. 



The nasal bones are considerably shorter than in the Tiger, and they 

 taper less upwards towards their frontal insertion.
