In his paper on the birds of Idaho, Dr. C. Hart Merriam writes : — " I found this 

 species abundant along Snake Hiver and Big Lost River in July. Common in Birch 

 Creek Valley until the middle of August ; a few seen afterward." The same author 

 observed the species also common in the parks of the pine plateau of San Prancisco. 



Mr. P. H. Lawrence, writing of the birds of Gray's Harbour, Washington Co., says 

 that the Violet-and-Green Swallow was a pretty common summer resident on the harbour, 

 especially at Hoquiam. None Avere noticed at Stevens Prairie, but it was common at 

 Acosta in April, and Mr. La^^Tence also noticed two individuals of the species at Astoria 

 in Oregon on the 27th of March. 



During the Lumholtz ArchE3eological Expedition to North-eastern Sonora and North- 

 western Chihuahua, the present species is recorded by Mr. Allen as having been obtained 

 at Bisbec and San Pedro in South-eastern Arizona, in July and August, and again at 

 San Diego on the eastern slopes of the Sierra Madre on the 25th of Pebrtiary. 



Mr. Belding, in his paper on the birds of the Pacific District, has given some 

 interesting notes on this bird's distribution which add considerably to our article given 

 above. He writes : — " Not noticed immediately on the coast abottt San Diego, ■\\ here 

 trees are scarce. My latest Californian record is ' Big Trees, September 25,' though 

 Dr. Cooper saw a large flock, Santa Cruz, Oct. 5. I have never found it breeding in the 

 valleys of the northern half of the State, where it is seen as a rare migrant. Al Murpliy's, 

 breeding in cliffs with Micropus n/elaiioleucus." 



Mr. Henshaw says that it is an " extremely abundant sturimev visitant in certain 

 portions of Eastern California and Western Nevada, as, for instance, at Pyramid Lake. 

 Thousands resort to the niches and holes in the faces of rocks for nesting-sites. In ihe 

 mountains, where it is also abundant, it selects for tiiis i)ur[)()so tlio deserted lioles of 

 Woodpeckers, giving preference to those in oaks." 



In the Volcan Mountains, Mr. O. Emerson noticed live birds living]: about for three 

 hours on St. Patrick's Day, when the snow was two inclies dee]). He .-ilso not iced a 

 Hock on the 30th of March, and on the 1st of April tlie birds were IrcMpienting the
