URSUS SPELAUS. 91 
In the same bone-cave, near Torquay, has been found 
the anterior part of the lower jaw, with the canines of 
corresponding magnitude, of the Ursus speleus, in which 
the small simple-fanged 
premolar close behind the 
canines has been retained 
on each side; and its 
crown has been flattened

tional instances of this 
retention of the teeth, 
which are commonly de- 
ciduous at an early period 
in the great Cave Bear, 
have been observed in 
lower jaws from the 
German and Belgian ca- 
verns. 
The fossil humerus, or 
arm-bone (jig. 30), of a 
large bear from Kent’s 
Hole, manifests all the 
characters of that bone 
in the Ursus  speleus, 
which appear to me to be 
as well marked as those 
distinguishing the humeri 
in any other two species 
of one genus. ‘ 
Cuvier conceived that Upper canine, fossil. 
- URSUS SPELAUS. 
he had met with two 
very distinct forms of fossil humerus, belonging to equally 
gigantic extinct species of Cave Bears. He says,—
