which must have been moulted only a short time before the birds in 

 question were killed, it would seem most reasonable to assume that the 

 latter are simply Leconte"s Thrashers in fresh autumnal dress, a- con- 

 dition which does not seem to have been previously examined. 



I take this opportunity of describing another hitherto unknown plu- 

 mage of lecontii. 



Juv., first plumage ( $ No. 894, F. S., Aqua Caliente, California) 

 March 28, 1S84. Coll. F. Stephens). Of the same general pallid sandy- 

 brown as the adult, but with the ochraceous of the anal region and crissum 

 paler, the upper tail-coverts brownish-rusty, the wing-feathers (but not 

 their coverts) delicate pearl-gray tipped with light brown, the tail dark 

 plumbeous-brown, and the dusky loral patch and malar stripe rather more 

 conspicuous than in the old bird. There is no indication of other dark 

 spots or streaks anywhere either above or beneath. This bird was 

 evidently just from the nest when taken, as its wings and tail are not fully 

 grown. 



Although Mr. Ridgway has expressed* his inability to verify certain 

 supposed peculiarities in the bill of this species, to which I once called 

 attention,! I have found them nearly constant in the dozen or more speci- 

 mens that have since passed through my hands. 



Certhia familiaris mexicana ( Glogcr) Ridgzv. Mexican Creeper. 

 — Two Creepers, an adult male and female, taken in the Santa Rita Mts., 

 July 5, are nearly, if not quite, typical examples of this strongly character- 

 ized subspecies, which was added to our fauna by Mr. Stevens in 1SS1. 



Dendrceca nigrescens (Towns.) Baird. Black-throated Gray War- 

 bler. — Juv., first plumage ( $ No. 2072, Santa Rita Mts., July 1). Above 

 brownish-ashy, somewhat plumbeous on the crown ; below ashy-white, 

 the throat dark ashy, the breast and sides sprinkled with fine, obscure 

 spots of dull black. The white stripes on the sides of the head are well- 

 defined but the lores are solidly black, lacking the yellow spot seen in the 

 adult male. 



Vireo huttoni stephensi Brews. Stephens's Vireo. — Juv., first plu- 

 mage (No. 2161, Santa Rita Mts., July 9). Above brownish-ashy tinged 

 with olive on the back, the wing- and tail-feathers edged with greenish, 

 the wing-coverts tipped with ochraceous ; below ashy-white washed faintly 

 with yellowish posteriorly. 



Vireo pusillus Coues. Least Vireo. — Juv., autumnal plumage ($? 

 No. 2501, Camp Lowell, Aug. 11). Very similar to the adult, but paler 

 and greener above, with a decided greenish edging on the wing- and tail- 

 feathers ; the under parts rather purer white. 



Pyranga hepatica Swains. Liver-colored Tanager. — Juv., first 

 plumage ($ No. 2163, Santa Rita Mts., July 9). Above dull yellowish- 

 green, brightest on the crown and tail, each feather with a broad shaft- 

 stripe of dark brown ; below sulphur yellow, more or less tinged with
