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 spelezus, in which 

 the small simple-fanged 

 premolar close behind the 

 canines has been retained 

 on each side ; and its 

 crown has been flattened 

 by attrition. A few excep- 

 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 Jiumerus, or 

 arm-bone (fig. 30), of a 

 large bear from Rentes 

 Hole, manifests all the 

 characters of that bone 

 in the Ursus spelteus, 

 which appear to me to be 

 as well marked as those 

 distinguishing the humeri 

 in any other two species 

 of one genus.

very distinct forms of fossil humerus, belonging to equally 



gigantic extinct species of Cave Bears. He says,
