FROM THE SIVALIK HILLS. 199 



the occipital. The parietals swell out backwards and downwards. Tlie 

 cranial cavity appears to have expanded much laterally, towards the occiput, 

 which is broken off. The temporal fossae are of great depth and extent ; 

 the zygomatic arches on both sides are wanting ; judging from the depth of 

 the temporal fossae they must have been of great expanse. The ' malar 

 apophysis comes off low and is inches in height. The nasals are partly 

 removed by a fissure in the fossil extending across the face. They appear 

 to have been rather long and the external opening of the nostrils to have 

 been much shorter and less oblique than in the Ursus spelceus. The muzzle 

 is broad and obtuse ; being about one-fourth of the length of the head, and a 

 little wider than the interorbitary portion of the frontal. In this respect it 

 resembles the Ursus labiatus. The palate is strongly arched both longitudin- 

 ally and transversely : the greatest depth from a line across the worn molars, 

 to its surface, being 2.3 inches. The horizontal plate of the palatines, 

 hardly extends an inch beyond the rear molar ; whereas in a head of the 

 Ursus labiatus measuring a foot in length, it extends more than two inches. 

 The palatine sinus is also proportionably narrow for the size of head. 



In place of a single suborbitary foramen, there are three distinct foramina 

 nearly of the same size, placed over each other and a few lines apart. They 

 are considerably advanced on the jaw, the uppermost being 1.6 inch from 

 the margin of the orbit and placed over the carnassier. It is difficult to say 

 whether this is common to the species or merely an individual peculiarity. 

 Nothing of the sort is seen upon the heads figured in the Ossemens Fossiles. 



We only know the lower jaw by the fragment represented in Fig. 1. 

 It consists of the greater part of the body of the right side, broken off 

 where the canine protrudes. It is also deficient in the articulating and 

 coronoid processes. There is therefore little to remark about the form. 

 The lower edge has a good deal of curvature backwards, and the outer 

 surface is deeply indented by a muscular hollow towards the angle. The 

 dimensions of the fragment are thus : 



Extreme length of the fragment 10.3 iucli. 



Height of jaw over 1st false molar 2.5 



Ditto hetween the two rear molars , 3.0
