Oregon and Washington Territories, especially coastwise, about the cliffs of the bays 

 and inlets. Dr. Cooper noted its arrival near the Columbia in May and its departure in 

 August. In his later work on Californian Birds, the latter records his first observation 

 of the bird at Port Mojave, on the 27th of February, but adds that he has seen them, at 

 San Diego on the 9th of November and 27th of January, ' so that if they do not winter 

 within the State, they do not go far beyond it.' .... In higher portions of Arizona, I 

 found it to be a common summer resident, arriving at Fort Whipple late in April, and 

 remaining through the greater part of September. Henshaw saw it in numbers in 

 Southern Colorado during May, and also about the puebla of Zuhi in New Mexico; it 

 was still more abundant at Provo, Utah, and other points in the same general area, 

 where also Mr. Ridgway attests its presence in great numbers. In some places, says the 

 last-named, it was the most numerous representative of the family next after the Cliff 

 and White-bellied Swallows ; it is generally distributed over the United States, excepting 

 most of New England, but not much further northward ; agreeing in this respect with 

 the Violet-green Swallow, and being, next after this species, more restricted in its habitat 

 than any other Swallow of North America." 



Our account of the Rough-winged Swallow, therefore, aims at supplementing the 

 excellent summary quoted above, and we trust that it will be found a tolerably exact 

 record of the observations of North-American naturalists since Professor Elliott Coues 

 wrote his ' Birds of the Colorado Valley.' 



We are first of all indebted to our friend Mr. Ernest E. Thompson, for some Canadian 

 notes as to the distribution of the species in Ontario : — 



" London. Regularly distributed and uniformly common all over this section. Also 

 noted at Hamilton. (For ' full details ' this is very slight on this species, but 

 it amply covers the ground.) They breed in any bank suitable, railway- 

 cuttings, gravel-pits, river-banks, it makes no difference, generally one, seldom 

 two, never three pairs breeding close together (W. E. Saunders). 



" Hyde Park. Summer resident {John A. Morden). 



" Toronto. As yet not observed here by anyone." 



The accompanying sketch is also sent by Mr. Thompson, who writes : —

 appears to trend along the north shore of Lake Ontario, and ultimately to run as far
