 LJuly 



(Brewster). (Brewster, Auk, X, July, 1893, p. 214.) Mr. Brewster 

 very generously lent me the type — an adult male — and only known 

 specimen of U. salvini, and I am quite confident my bird is the same, 

 and that the species is a valid one. 



My bird resembles the type very closely, differing from it only in the 

 following particulars, which, with the possible exception of the color of 

 the bill, are what were to be expected in the young. The blue iridescent 

 feathers of the crown are duller; the green back duller with the iridescent 

 feathers more restricted; the lower back paler; the upper tail-coverts 

 and rectrices more bronze; the iridescent blue and green feathers of the 

 sides of neck and breast duller, fewer and more restricted; and the sides 

 of the body brownish gray instead of bright green. The feathers of the 

 upper parts, especially the lower back and rump, are edged with pale 

 rusty, as is usual with young hummingbirds. Both have the white lower 

 tail-coverts, clayey buff wash on throat, and pale tips to the rectrices. 

 The bill of the young bird is slightly broader, the maxilla darker, being 

 the same brownish black at tip and becoming dull reddish brown only 

 at base; and the mandible paler and more yellowish except at tip. The 

 measurements of the two are practically identical. 



Nacosari, where Mr. Brewster's bird was collected, is only about 80 

 miles from Palmerlee; while Mr. Oberholser informs me that U. verticalis 

 (quadricolor) its nearest geographical ally, has not been taken north of 

 Durango. 



Thanks to Dr. Allen, I have compared my skin with adults and young 

 of other members of this genus in the Elliot collection of the American 

 Museum of Natural History, and find it much smaller than U. verticalis 

 and resembling it in plumage only very slightly. It more closely ap- 

 proaches U. cyanocephala and U. cyaneicollis, but has a longer bill and 

 shorter wing than either; cerulean blue crown, and on sides of neck, 

 instead of purplish blue, bluish green or green; bluish green upper back 

 instead of golden green or green; and white under tail-coverts. Mr. 

 Oberholser tells me it differs in a similar manner from U. violiceps. 



My thanks are due to the above ornithologists and to Mr. D. G. Elliot 

 and Mr. J. H. Fleming for their assistance in identifying the bird.
