probably due to sex and age, three of the specimens being 

 young. 



The best specimen is No. 18275, male, represented by a 

 nearly perfect skin and skull. It was killed on Baronesskorf 

 Gulf (Olutorski Bay of some maps), and purchased of the 

 natives by Mr. Bogoras. This specimen is referred to Mid- 

 dendorfTs Ursus arctus var. beringiana. The specimen he 

 describes and figures under this name, he informs us, came 

 from Great Schantar Island, which is situated in the western 

 arm of the Okhotsk Sea (Uda or Udski Bay), so that this, 

 island may be taken as the type locality of the species. An- 

 other specimen is figured and described from "Uda-Bucht," 

 at the mouth of which is situated Great Schantar Island. 

 The locality of the present specimen is on the east coast of 

 Siberia, nearly opposite the head of Okhotsk Sea. 



The specimen is obviously in full winter pelage and is a beau- 

 tiful skin. The general color is very dark reddish brown,, 

 darker, or blackish brown, on the limbs. The hairs on the 

 back are tipped with lighter, the light tipping increasing rap- 

 idly in length from the middle of the back anteriorly, and 

 becoming lighter in color, so that over the shoulders the pre- 

 vailing color is yellowish brown, passing on the nape and 

 crown into pale golden fulvous. The front of the head, from 

 the forehead anteriorly, is dark brown with a tinge of fulvous,, 

 particularly on the sides of the nose anterior to the eyes. 

 The claws are strong and curved, those on the hind feet much 

 worn. The longest front claws have a length of 70 mm. along 

 the convexity, and 45 along the arc; the longest hind claw 

 measures 40 mm. over the convexity and 17 along the arc. 

 The length of the flat skin is 1975 mm.; the expanse from 

 tip to tip of the extended fore limbs, 2271 mm. 



The skull indicates a middle-aged animal, the sutures being; 

 still quite distinct and the teeth almost wholly unworn. Its 

 striking features are the great breadth of the frontal region, 

 the swollen postorbital processes, and the deep median hollow 

 between them. Compared with skulls of Ursus middendorffi 

 Merriam, from Kadiak Island, of corresponding age and sex, 

 the breadth of the skull is much greater in proportion to its-
