 Snake River, Wyo. 



_H"rt&. — United States from Atlantic to the Eocky Mountains, where 

 they become mixed up with Z. gamhelU Greenland, Eeinhardt. 



Madison River was the first place on our route where we met with 

 this finch. There they were quite abundant, as they were at Lewis's 

 Lake, where I obtained a fine specimen in winter plumage. Here they 

 were very shy, and it was with great difficulty that I secured a single 

 specimen. We also found them in considerable numbers along Snake 

 Eiver.

Fort Hall, Idaho. 



Sah. — Eocky Mountains to the Pacific coast. 



We met with a few flocks of these birds at Yellowstone Lake, and at 

 Fort Hall, where I obtained one specimen. No. 300, (62299.) This spe- 

 cies is almost exactly like the preceding, Z. leucojjhrys, the only notice- 

 able difference being in the black stripe on the side of the crown, which, 

 in leiwoplirys, passes down over the upper half of the lores and in front 

 of the eye, sending back a short branch to it, which cuts olf the white 

 superciliary stripe. In Z. gamhelii the superciliary stripe passes continu- 

 ously forward to the lores, cutting off the black from the eye. In habits 

 it resembles the white-crowned finch just described.
