Brewster on Birds from Arizona and Mexico. i April 



green, the feathers everywhere — exceptor! the crissurri and under tail- 

 coverts, which are immaculate — streaked centrally with dull black. 



Pyranga aestiva cooperi Ridgw. Cooper's Tanager. — Juv.. first 

 plumage ( $ No. 2500, Camp Lowell, Aug. 11). Above dull brownish- 

 ochrey; below brownish or ashy white; the feathers of the crown and 

 back streaked centrally with dark brown, those of the breast aud abdo- 

 men with dull black. This specimen is a little past the true first plu- 

 mage, patches of the autumnal feathering having already appeared in 

 places. 



The adult male of this subspecies, as shown by a specimen taken Sept. 

 1 at Tucson, does not have a distinctive autumnal plumage, the red at 

 that season being quite pure and, indeed, apparently even deeper and 

 rosier than in spring. In this respect the bird resembles its near rel- 

 ative P. cestiva and differs from P. rubra, the adult male of which in 

 autumn assumes a green livery scarcely distinguishable from that of the 

 female. 



Passerculus rostratus ( Cass. ) Baird. Large-billed Sparrow. — Two 

 females were taken Aug. 20 on the shore of the Gulf of California at 

 Port Lobos, Sonora, Mexico. Mr. Ridgway, who has kindly examined 

 them, confirms my opinion that they are typical rostratus. 



Centronyx bairdi {And.) Baird. Baird's Sparrow. — Two adult 

 males, in worn and very ragged breeding plumage, were taken respectively 

 Aug. 29 and 30, in Southern Arizona, eight miles north of the boun- 

 dary line, and ten miles northeast of Sasabe, Sonora, Mexico. The 

 dates of capture and condition of these specimens would seem to imply 

 that the species breeds in Arizona. 



Passerina versicolor (Bonap.) Gray. Varied Bunting. — A female, 

 apparently adult, but in perfectly fresh, unworn plumage, was taken 

 July 14 at Crittenden, near the Santa Rita Mts. I can find no previous 

 record of the occurrence of this species in Arizona. 



Junco cinereus {Swains.) Cab. Mexican Junco. — Juv., first plumage 

 (J No. 2102, Santa Rita Mts., July 5). Top and sides of head dusky- 

 ash; under parts ashy-white; chestnut of back spreading over the wing- 

 coverts and inner secondaries as in the adult; entire plumage of head 

 and body — except the abdomen and crissum, which are immaculate — 

 thickly spotted and streaked with dull black; lores black. 



Sturnella magna mexicana (Set.) Rigdw. Mexican Meadow Lark. — 

 Two Meadow Larks, a male and female, taken respectively July 22 and 24 

 at Crittenden, Arizona, prove rather unexpectedly to be typical mexicana. 

 As this form — closely related to magna of the East — seems never to have 

 been detected before to the westward of Texas within the United States, 

 its occurence in Arizona, in the heart of the neglecta country, is not less 

 interesting than unexpected. 



Myiarchus mexicanus magister Ridgvj. Arizona Crested Fly- 

 catcher. — Juv., first plumage ( $ No. 2434, Camp Lowell, Aug. 5). 

 Generally similar to the adult, but with the crown tinged with reddish, 

 the back duller brown, the throat paler ash, the outer edges of all the wing-
