Kv.iv THE BIG GAME OF ALASKA 55 



The zygomatic arches are very much higher than in specimens 



3 and 4. 

 Sagittal ridge well defined and high, frontals concave. First 



molar tooth in upper jaw \\ inch long. 

 The animal was very dark in colour, and appears to be undoubtedly 



Ursus dalli gyas. 

 Skull No. 3. — Young male. Aniakchak Bay, Alaska Peninsula. 

 Basal length from back to front, i2| inches. 

 Width across zygomatic arches, 6| inches. 

 Weight clean, 2 lbs. 12 oz. 

 Conforms generally with No. 4. 

 The colour of skin was a light cream colour. Believed to be 



Ursus kiddei'i.

 Basal length from back to front, 17 J inches. 

 Width across the zygomatic arches, 9^^ inches.

 The sagittal ridge in this skull is not much developed. Frontals 



slightly concave, but quite different from No. 2. 

 In colour the coat of this bear was considerably lighter than in 



either of the other adult males. 

 The dentition and cranial peculiarities are quite different from 



those of No. 2. I believe this to be Ursus kidderi.

 Basal length from back to front, 12^ inches.

No. 2 or 4 as regards dentition. Very dark-coloured skin. 



Species not determined. 

 Skull No. 7. — Adult female. Bear River, Bering Sea coast. 

 Basal length from back to front, 14^^ inches.
