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

 Ogden Canon, 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 Gaiion of the Yellowstone. There I saw a few 

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

 through most of the United States. 



As the shrike or butcher-bird 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, (62270.)

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. 43, (61752.) 

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