small and simple-fanged premolar in the interspace, or 

 diastema, between the canines and the double-fanged mo- 

 lars. Similar, but rare instances, from Continental caves, 

 of this variety in the Ursus spel&us, have been noticed 

 above. 



Amongst the bones of the trunk and extremities of the 

 Ursus spelaeus from Kent's Hole, there occur remarkable 

 examples of diseased action ; a lumbar vertebra, for ex- 

 ample, presents extensive exostosis from the under part 

 Fig. 34. and sides of the body ; the 



distal extremity of a radius 

 (fig. 34) exhibits an oblique 

 fracture of that bone, in the 

 attempt to heal which a new 

 and irregular ossific mass has 

 been deposited on the surface 

 of the bone. Several bones 

 and teeth of the Bear from 

 Kent's Hole exhibit very 

 decided marks of having 

 been gnawed, most proba- 

 bly by a hysena. One of 

 the fragments of the lower 

 jaw of a young Bear (fig. 

 36) shows the same interest- 

 ing transitional state of den- 

 tition which has been dis- 

 covered in fossils from the 

 Continental Bear-caves. The 

 Fossil, 4 nat. size. pom t o f the permanent ca- 



nine (I) has just protruded from its socket, and the crown 

 of the last molar (m) is hollow and without a fang. 



The unstratified drift and newest tertiary strata in 

 several localities of England have yielded remains of
