 "Shore of Arctic Ocean, on west side of Bathurst Inlet near 

 mouth of Hood River." (Merriam) 



Xanana Grizzly. — Ursus phcBo?iyx (Merriam). 



"Size of male large; of female small (sexual disparity great, 

 much greater than in dalli). . . . Upperparts varying 

 from creamy or buffy to dark 'grizzly color'; underparts 

 and muzzle pale brown; legs very dark brown, varying to 

 blackish brown; claws horny and smooth, usually dark but 

 sometimes marked with whitish. Last upper molar of 

 medium size or rather small." Found in "Tanana Moun- 

 tains between Tanana and Yukon Rivers." (Merriam) 



Kidder Bear. — Ursus kidderi kidderi Merriam. 



Size medium, much smaller than gyas, which is found in the 

 same region. "June specimens (in left-over winter 

 pelage) : General color yellowish brown, darkest on belly 

 and legs, legs much darker than body. Most of the Kidder 

 bears in the National Zoological Park are pale buffy yellow- 

 ish, or yellowish cream color." Found in "Alaska Penin- 

 sula for its entire length." (Merriam) 



Alexander Grizzly. — Ursus alexandrcB Merriam. 



' ' Size very large ; skull long and narrow ; rostrum exception- 

 ally broad for a grizzly; pelage very uniform in color, 

 scarcely or not grizzled ; claws enormous (second foreclaw of 

 type specimen measuring: length from upper base, 91 mm.; 

 height at base, 25; breadth, 11.5). The longest claw in a 

 specimen collected by Wilson Potter measures 120 mm. ; in a 

 male killed by Dall DeWeese, no mm. . . . Among the 

 grizzlies it stands alone in the great breadth of the rostrum, 

 which in bears of its size is only exceeded by the widely 

 different kenaiensis. Ursus alexandrce attains the largest 

 size known among the grizzly bears, the biggest skulls 

 equaling those of the huge magister of Southern California. 

 "Color. — Type, very old male, in fresh short fall pelage: 

 General color pale, almost grayish brown, becoming yellow- 

 ish brown between ears, contrasting with pale brown of 

 muzzle; legs and feet only slightly darker than back; entire 

 animal remarkably unicolor; under-fur plumbeous, crinkled, 

 and wooly. Another male, killed by Wilson Potter, of 

 Philadelphia, in May, 1912 (belonging to skull No. 181 102,
