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.

 Basal length from back to front, i2f inches. 

 Width across zygomatic arches, 6f inches.

 Basal length from back to front, \']\ 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.

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