7S J-/:': : — Tiro JN'tftr Bears from Alaska. 



this I take pleasure in naming it in honor of Mr. Kidder, who 

 has brought back the first series of skins and skulls, accom- 

 panied by reliable data, of the Alaska brown bears, and who 

 has generously presented the type specimen to the Biological 

 Survey Collection of the U. S. National Museum. 



In the same connection I have examined the large Alaska 

 Peninsula bear, of which the Biological Survey Collection now 

 contains a fine series of skulls. Briefly, this bear proves to 

 differ so markedly from both the Kadiak and Takutat bears 

 that I am obliged to name it also, and have recognized it as a 

 subspecies of Ursus dalli. with which its range is probably con- 

 tinuous.

Characters. — ^Similar to VrfUi daUi but very much larger: about the 

 size of Cr**- ■ ■ " " l^^ from Kadiak Island. 



Sknll Sim _ :3d to that of daUi but much larger, heavier and

e.r.i'.T^; anterior nares very much larger, particularly higher: teeth 



larger. 



From Vn 'yrgi of Kadiak Island, with which I originally 



ccaifounded the big Alaska Peninsula Bear, it may be distinguished at 

 once by the much smaller anterior nares. The nares are much larger 

 than iQ i'iU.i but much smaller and less fiaring than in middertdorifi. It
