160 EXTINCT AND VANISHING MAMMALS 



ALASCENSIS GROUP 



Ursus alascensis Merriam. ALASKA GRIZZLY 



Range: Norton Sound region, Alaska, south to Chinitna, on 

 Cook Inlet; limits unknown. Osgood (1901, p. 68) at the 

 beginning of this century wrote that "large bears are still very 

 often seen both on the Alaska Peninsula side of Cook Inlet and 

 on the mountainous Kenai Peninsula. According to report 

 they were very abundant about ten years ago, but in the short 

 time since have been so constantly pursued that their numbers 

 have been greatly reduced." Probably this local form requires 

 protection if it is to survive, but no recent report is at hand. 



Ursus toklat Merriam. TOKLAT GRIZZLY 



Range: "So far as known, restricted to Alaska Range" 

 (Merriam). The type specimen came from the head of 

 Toklat River, north base of Alaska Range, near Mount Mc- 

 Kinley, Alaska. Since this region is now a national part, 

 there seems to be no immediate cause for anxiety for the 

 continued existence of these bears in their range. 



Ursus latifrons Merriam. BROAD-FRONTED GRIZZLY 



Range: Rocky Mountains of western Alberta and eastern 

 British Columbia from Jasper House northwesterly to head- 

 waters of Stikine River. Probably the same remarks apply to 

 the status of this bear as to that of Ursus crassodon. Some 

 numbers may still occur. 



RICHARDSONI GROUP 



Ursus richardsoni Swainson. BARREN-GROUND BEAR 



Range: The type came from the shore of the Arctic Ocean 

 on the west side of Bathurst Inlet, near the mouth of Hood 

 River, and probably is representative of the animal of northern 

 and northeastern Mackenzie. Anderson notes that of late 

 years with the extension of reindeer herding by the natives, 

 these regions, which previously were but little hunted, may 

 now be more often patrolled and these bears are likely to be 

 in a much more precarious situation than formerly. 



Ursus russelli Merriam. MACKENZIE DELTA GRIZZLY 



Range: Lower Mackenzie region; limits unknown. Of the 

 barren-ground bear in general, Preble (1908) states that it is 

 rare over the greater part of its range. Probably it is not
