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 speleus, have been noticed 
above. 
Amongst the bones of the trunk and extremities of the 
Ursus speleus 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 
a! 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 haying 
been gnawed, most proba- 
bly by a hyena. One of 
the fragments of the lower 
jaw of a young Bear (jg. 
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, } nat. size. point of the permanent ca- 
nine (7) has just protruded from its socket, and the crown 
of the last molar (7) is hollow and without a fang. 
The unstratified drift and newest tertiary strata in 
several localities of England have yielded remains of
