remains of two species of bears : besides less differences, the coronoidal 

 apophysis is much wider in the more common of the two species than in 

 the other, the width being as 10 to 8, although the teeth are a little 

 larger in the latter species. M. Cuvier was disposed to arrange the lat- 

 ter species with the rounded skulls; but on considering that the rounded 

 skulls were most frequent, and this species of jaws most rare, he found it 

 difficult to determine on this point. 



No remains of scapulae have been found of sufficient size to allow any 

 judgment being formed respecting the animal to which they belonged. 

 Two sorts of os humeri have been found, as figured by Mr. John Hun- 

 ter, Trans. Phil. 1794, PL xx. both belonging to the bear, but the one 

 differing from the other in having a hole above the internal condyle for 

 the passage of an artery, much resembling, in this circumstance, the os 

 humeri of some animals of the genus Felis. Of the radius, the ulna, and 

 the bones of the 'pelvis, nothing particular can be ascertained. Two 

 kinds of ossa femoris, both decidedly of the genus Bear, but one much 

 shorter and thicker than the other, have been found. A tibia has also 

 been found, which, from its being thicker in proportion to that of the 

 common bear, M. Cuvier is disposed to place with the preceding os 

 femoris. With this bone he also places part of a fibula which is in the 

 Museum. 



Like the present bears, and several of the carnivorous animals, the 

 bears of the caverns have seven carpal bones; and which, with the me- 

 tacarpal bones, differ very triflingly from the bones of the existing bears. 

 A similar agreement with those of the existing bears is observable in the 

 tarsal and metatarsal bones. 



Numerous vertebrae are found in these caverns, the greatest number 

 of which appear to agree very closely with those of the existing bears. 

 The last dorsal vertebra was however found under two distinct forms : 

 one resembling that of the brown bear, and the other approaching to 

 that of the polar bear, especially as the posterior supernumerary apo- 

 physes were not so long as the articular ones. Here M. Cuvier sup-
