This species is mentioned by both Dr. Pickering and Mr. Peale, as 

 having been observed in Oregon, but unfortunately no specimens are 

 preserved in the collection. This circumstance is the more to be 

 regretted, as an opportunity would have been presented of comparing 

 specimens from the opposite sides of the continent. The species inha- 

 biting Oregon has been named umhelloides, by the celebrated traveller, 

 Douglas, and differences, apparently quite sufficient to establish specific 

 distinction, have been pointed out, in the journal above cited. The 

 most important character is the larger size of the western bird ; " the 

 northern bird" (obtained in Canada), he says, "is constantly one-third 

 smaller." 



Dr. Pickering mentions this bird under date of the 22d of May, at 

 Puget Sound, Oregon : 



" In specimens of Tetrao umhellus, obtained here, I can see no mate- 

 rial difference from the Ruffed Grouse of the United States. But the 

 bird here appears to be much more arboreal in its habits, and is fre- 

 quently to be observed in the tops of trees, which is very rarely the 

 case, I believe, with the eastern bird. Iris brown ; wings concave, 

 and quite short." 



Mr. Peale states : 



" Observed in abundance near the Columbia River, but not south of 

 the Elk Mountains, lying north of the Umpqua River. It is subject
