TETRAON^ID.E — THE GROUSE — LAGOPUS. 



543 



Hah. High alpine rej;ions of the Eofky ^Mountains, from Jfew Jlexico to the i\a'ctic 

 Ocean. Also highest peaks of Washington Territory, and Briti:^h Columbia. 





The fact tliat the tail feathers, whicli on the other species of Lagoims are 

 always black throughout the year, are here entirely white, will serve to dis- 

 tinguish the species at once from all its congeners. Formerly but little 

 known in the United States, and its first introduction based on specimens 

 collected in the Cochetope Pass of the Eocky Mountains (lat. 39°), liy Cap- 

 tain ]\Iarcy, in 1858, this species lias now come to be a familiar member 

 of the alpine regions of the Rocky ^fountains, as depicted by artists and 

 authors. (Baird.)
