"The present paper is merely a review of the 

 existing state of knowledge of the grizzlies and big 

 brown bears of America and does not include 

 either the polar or the black bears. It is not in- 

 tended as a monographic revision, but aims to 

 supply a list of the species, together with descrip- 

 tions and comparisons of adult skulls, chiefly males. 

 Little is said of external characters, for the reason 

 that little is known, only a few skins with claws 

 being available for study.

 but the species appears to be impossible of identification."
