The Birds of Wyoming. 55 



common. While climbing Cloud Peak in 1897 I found these 

 birds at an elevation of 11,500 feet, in localities where there 

 was little vegetation and apparently nothing for them to eat. 

 Coues reports this variety from the Yellowstone river and the 

 Wind River mountains. Grinnell reports them from the Yel- 

 lowstone Park. 



300a. Bonasa umbellus togata (Linn.). 

 Canadian Ruffed Grouse. 



Resident and common in northeastern Wyoming along the 

 western slope of the Black Hills and in the Bear Lodge moun- 

 tains. They are found along some of the streams in the north- 

 ern Big Horn mountains and westward into Idaho. Several 

 birds have been reported from southwestern Wyoming. Bond 

 has one specimen in his collection that was killed near Fort 

 Bridger, and there is a skin in the University collection that 

 was taken by West in the vicinity of Buffalo. 



300 b. Bonasa umbellus umbelloides (Dougl.). 

 Gray Ruffed Grouse. 



Resident and quite common in northwestern Wyoming; 

 but unknown in the southeastern part of the state. This 

 species of Ruffed Grouse is much more common in the desirable 

 localities than the previous one noted. Drexel found this species 

 at Fort Bridger, 1858; McCarthy found them in the same lo- 

 cality in 1859 ; Allen reports them from Wyoming and Montana, 

 1 87 1 ; Grinnell reports them from the Yellowstone park in 

 1875. There is one skin in the University collection that was 

 taken by West at Buffalo. I found this species quite common 

 along the Snake river in Jackson's Hole in 1894. 



304. Lagopus leucurus altipetens Osgood. 

 Southern White-tailed Ptarmigan. 



Resident and quite common in alpine districts. Thev are 

 seldom seen below timber line. The only Wyoming record is 

 based upon my own observation in the Medicine Bow moun-
