GEOLOGICAL SURVEY OF THE TERRITORIES.

This bird, the most beautiful of all the swallows, is quite common at 

 Ogcleu Oaiiou, where we obtained the only specimen collected — No. 96, 

 [61665.) The only other place on our route at which we found this 

 species was the Grand Canon of the Yellowstone. There I saw a few 

 of them, but did not succeed in obtaining any specimens. 



Cotyle riparia, Boil., (bank-swallow :) 



Kah. — United States, from Atlantic to Pacific ; common at Salt Lake, 

 and from there to Snake River. 



I obtained the nest of the bank-swallow in a hole in a sand-bank by 

 the side of Salt Lake. It contained seven fresh eggs — No. 25, (1G295J) 

 9 , No. 40, shot. 



Family 13. — Laniid^, the Shrikes. 

 Colhirio horealis, Baird, (great northern shrike:) 



Hah. — Northern regions, from Atlantic to Pacific ; in winter south, 

 through most of the United States. 



As the shrike or butcher-btrd is confined to the cooler portions of 

 America, it was met with by our party but once, and that was in Octo- 

 ber, at Fort Hall, Idaho Territory. There I secured one specimen. No. 

 297, (02270.) 



Collurio excichitoroides, Baird, (white-rumped shrike :) 



Hah. — Missouri plains and fur countries to Pacific coast ; eastward 

 into Wisconsin, Illinois, and Michigan. (?) 



Salt Lake and Fort Hall are the only localities at which I found the 

 white-rumped shrike. At the former place, on the 11th of June, I saw 

 a pair of them, and succeeded in shooting the female — No. 13, (01752.) 

 It is evident, from the lateness of the season, that tbey breed here.
