This species appears to be far more distinctively eastern iu its distribu- 

 tion than the preceding, though several citations, as above given, show its 

 occurrence in the Far West, even in California. In nearly every case, how- 

 ever, their numbers when compared with the Rough-winged are small. On 

 the Provo River, Utah, it was observed by Dr. Yarrow and myself to be 

 quite common and intimately associated with the Rough-winged Swallows, 

 both species breeding in the same banks together. Indeed, the flight and 

 general appearance of the two are so much alike that when both species 

 were found skimming the surface of the river together it needed the most 

 careful scrutiny to distinguish them.
