NORTH AMERICA AND THE WEST INDIES 161 



likely to persist about the mouth of the Mackenzie for any 

 great length of time. 



Ursus phaeonyx Merriam. TANANA GRIZZLY 



Range: "Tanana Mountains between Tanana and Yukon 

 Rivers," Alaska. Dr. W. H. Osgood, who obtained the type 

 specimen in 1903, wrote that "very little accurate information 

 is obtainable in regard to the grizzly in the Yukon region," 

 and this state of affairs seems to continue. However, with the 

 development of mining interests and settlement, it is not likely 

 that this form of the middle Yukon will resist encroachment 

 for many years. 



Ursus internationalis Merriam. ALASKA BOUNDARY GRIZZLY 



Range: "Region bordering Arctic coast along international 

 boundary, and doubtless adjacent mountains, between the 

 coast and the Yukon-Porcupine; limits unknown." Status 

 not determined. 



Ursus ophrus Merriam. HIGH-BROWED GRIZZLY 



Range: The type, collected in> 1915, came from an unknown 

 locality in eastern British Columbia. Nothing further is 

 known of its status. 



Ursus washake Merriam. WASHAKIE GRIZZLY 



Range : The type came from the north fork of the Shoshone 

 River, Absaroka Mountains, in western Wyoming, between 

 Bighorn Basin and Yellowstone National Park. Since the 

 characters distinguishing the form are to be found in the skull 

 and teeth it is not possible to say what portion of the many 

 grizzlies found living in western Wyoming are like it. 



KIDDERI GROUP 



Ursus kidderi kidderi Merriam. KJDDER'S BEAR 



Range: "Alaska peninsula for its entire length." According 

 to the report on Alaska bear sanctuaries issued by the U. S. 

 Department of Agriculture in December 1939, "information 

 from . . . the Alaska Peninsula . . . leaves no question 

 as to the plenitude of the huge brown bears," so that with the 

 continuance of protective legislation no fears are felt for them.
