Klamath was the first point at which I obtained undeni- 

 able proof of its presence. The grouse of this region, 

 while referable as above, do not typically represent the 

 variety sabini, which reaches its maximum of develop-

 only on the Pacific slope. 



Camp Harney. Beiidire. Moderately common in 

 the John Day River Valley. 



12. Lagopus rupestris (Gmel.) ROCK PTARMIGAN. 

 British Columbia. John Fannin. Common resident. 



13. Lagopus leucurus Swains. WHITE-TAILED PTAR- 



MIGAN. 



British Columbia. John Fannin. Common resident 

 east of the Cascades.

 Farther north in Oregon, and especially on the grassy
