200 FOSSIL BEAR OF THE SJVALIK HILLS. 



We have not yet found out or identified any bones of the trunk or 

 extremities. The species does not appear to have been abundant, as no other 

 specimens of the head or teeth have been discovered, so far as we know, 

 among the immense collections of fossil bones got from the Sivalik Hills. 



The dimensions of the cranium, contrasted with some of the measure- 

 ments of the Ursus spelceus for comparison, are thus :

* These two measurements are incomplete in the fossil, from the mutilation at the occiput. 

 The first or extreme length is 17 inches or .434 metres, the second 7.7 inch or .197 metres. 



To conclude. It follows, that there existed along with the Mastodon, 

 Sivatherium, Fossil Camel, &c, of the Sivalik deposits, a large distinct 

 species of Bear, equalling if not exceeding the largest known of the genus. 

 Its teeth deviated widely from the type of the genus, approximating it more 

 to the higher Carnivora than to any other species ; the carnassier teeth 

 of the upper jaw connecting it with the Hy^na while the tuberculars have a 

 more remote analogy with those of the Dog. The size and extent of the 

 temporal fossie and the prominence of the sagittal crest, taken in conjunc- 

 tion with the teeth, show that it had a more strictly carnivorous than a 

 frugiverous habit. 



We have designated it Ursus Si valensis.
