IV. COMPARISON OF THE CAVE, BROWN, AND GRIZZLY BEARS. 



The subject of the mutunl relations of the Pleistocene bears is one of very great 

 difficulty, and very varying opinions have been expressed as to the number of 

 species. Most palaeontologists have recognised three species, viz., U. spelseus, U. 

 horribilis (=ferox, = feroxfossilis, = prisons), and U. arctos. Owen, Busk, Boyd
