The wild Turkey is a permanent resident of the mountains of the immedi- 

 ate vicinity of Whipple, but quite rare, so much so that I procured no speci- 

 mens. In some portions of the Southern Rocky Mountain region it is exceed- 

 ingly numerous. 



I have never detected any of the Tetraonidce in Arizona, though very pro- 

 bably the Centrocercus urophasianus may be hereafter found towards the Utah 

 border. Dr. Cooper has seen it on the Mojave River, about the southernmost 

 point it has yet been observed. 



Among the Lagopidce, the Lagopus leucurus has been detected as far south 

 as Cantonment Burgwyn, in New Mexico, (lat. 37,) and most probably will 

 be found in the mountains near the northern border of the Territory.

The common and characteristic Quail of the Southern Rocky Mountain re- 

 gion from the Rio Grande to the Colorado, and south into Mexico. Replaces 

 the L. californica. The two species have been found associated at Soda Lake, 

 the sink of the Mojave River. 



In my paper, as above, will be found some account of the habits of this 

 Quail, which I had previously, in the same Journal, (Ibis, 1865, p. 165,) 

 incidentally mentioned erroneously as L. " calif 'ornicus." From a large 

 suite of specimens, lean describe the following stages from the callow state to 

 the fully adult condition. 



Downy state, a few days old. Bill bright reddish above, nearly white be- 

 neath ; feet dull flesh color. Head yellowish white tinged with grayish brown ; 

 the occiput with a broad spot of pure brown ; on the centre of the crown 

 I whence the plume will spring) a few black feathers, each longitudinally 

 streaked with white. Entire upper parts brownish gray, (color of the lighter 

 parts of the back of a Sturnella,) mottled with spots of black, and very con- 

 spicuously streaked with long, sharply pencilled lines of white. Primaries 

 dusky, their outer vanes marbled with brownish black and grayish white. 

 Whole under parts from the white jugulum narrowly and semiconfluently 

 barred with black and ochraceous white, and longitudinally streaked with 

 short but distinct lines of pure white. This coloration is most marked and 

 definite on the breast ; on the flanks and under tail coverts the markings are 

 duller and moie blended. The newly sprouted tail feathers are colored like 

 the primaries. Length about 3| ; wing 1| ; tail J. This stage may be seen 

 up to the last of August. 



Quarter grown. (Aug., Sep.: length 6 or 7 inches.) The general hue is 

 dull leaden gray, becoming ochraceous on the scapulars and wing coverts, 

 which are still a little mottled, as described above. Below the gray is very 

 light indeed, almost wliitish, especially on the chin and middle of the belly. 

 Breast obsoletely waved with light and dark shades of gray, with s'ill some 

 slight traces of the white longitudinal lines ; the crissal and anal regions the 

 same, but somewhat tinged with brown. On the sides under the wings there 

 is a slight fulvous or ferrugineous tinge, but nothing like definite strips. Pri- 

 maries plain dusky ; tail more plumbeous ; very finely marbled with blackish 

 and whitish. There is a broad superciliary white stripe extending to the ex- 

 treme occiput. 



During first autumnal moult. (Sep., Oct., Nov.) The preceding two plu- 

 mages are those of chicks, with few true feathers. When the autumnal moult 

 has made some little progress, the features of the adults begin to appear, 

 mixed in a varying degree with the preceding downy colors. Some of the
