streak over auricular^ ; sides of neck streaked with the same ; an indistinct dusky streak on 

 side of throat ; belly dull white ; crissum buff; edge ot wing bright yellow; bill pale horn- 

 color, darkest above; feet pale brown; iris brown. Size of cestivalis; wing a little longer, 

 2.35-2.60, average 2.50; tail 2.55-2.80. average 2.70; bill thicker; black streaks of upper 

 parts, instead of being generally distributed, few and confined to the interscapulars ; breast and 

 sides more bufi"y. Thus much like (Estivalis proper, but quite different from any of the follow- 

 ing forms. Southern states at large, from southern Virginia, southern Indiana, and southern 

 Illinois, to Florida and Te.xas, breeding in most of its range, but migratorv to some extent, its 

 range including that of true cestivalis only in winter • casually N. to Maryland (Auk, 1897, 

 p. 219). This is the genuine original " Bachman's Finch" of Audubon (type examined: see 

 Brewst. Auk, Jan. 1885, p. 105). When the species was divided into its two subspecies, 

 Mr. Eidgway unluckily named the wrong one ; fur he identified P. hachmani with the dark 

 coast form from Georgia and Florida, which is true (sstivalis, and accordingly gave a new name 

 to the reddish bird of the interior, calling it P. illinoensis in Bull. Nutt. Orn. Club, iv, 1879, 

 p. 219. It consequently stands as P. cb. illinoensis in the 2d-4th eds. of the Key, 1884-90; 

 but must be known as P. ce. hachmani, as in the A. 0. U. Lists, 1886 and 1895, No. 575 a; 

 and -the required change in the English names of the two forms must also be made. 

 P. arizo'nae. (Of Arizona.) Arizona Summer Finch. With a general likeness to asti- 

 valis, in pattern of coloration, streaking of all upper parts, similarity of back to crown, yellow 

 edge of wing, and plain tail-feathers ; size same, wing and tail a triiie longer (as in hachmani). 

 Colors duller and less variegated ; maxillary stripes obscure or obsolete. Upper parts light 

 dull chestnut or reddish-brown, moderately streaked with plumbeous-gray, but reddish the 

 prevailing tone ; interscapular feathers, and sometimes those of crown, with blackish centres ; 

 a poorly defined light superciliary stripe. Beneath, dull whitish, unstreaked, breast and sides 

 with a decided ochrey-brown tinge. Wings dusky, inner secondaries darker and with more 

 conspicuous rusty-brown edgings than those of longer quills, and also some whitish edging or 

 tipping. Bill blackish above, pale below; legs flesh-color. Young: Above streaked with 

 blackish and yellowish-gray, showing little reddish ; under parts more or less streaked with 

 dusky. Southern Arizona and southward in Sonora. (This is in part what I meant by P. 

 var. cassini -of orig. ed. of Key; but true cassini is entirely different.) P. (estivalis arizonce

 and 2d eds. 1886 and 1895, No. 576. The bird is distinct from the foregoing, but I doubt 

 that it is specifically separable from the following : 



P. mexica'na. (Lat. Mexican.) Mexican Summer Finch. Very similar to the last. 

 Adult $ 9 : Upper parts gray suffused with bay, streaked on most of back with bold black bay- 

 edged stripes ; crown similar, rather darker in smaller pattern of markings and without lighter 

 median line. Bend of wing yellow ; coverts blackish, with .broad grayish-bay edgings ; flight- 

 feathers dusky, several inner secondaries blackish, with firm light edgings. Tail-feathers 

 dusky, with obsolete scarcely discernible cross-waves, middle pair with paler edges their whole 

 length, lateral ones fading toward their ends. Under parts pale grayish-brown, blanching on 

 throat and abdomen, unstreaked excepting for a slight pair of black maxillary stripes. Bill 

 dark horn-color; feet light brown. Length 6.30; wing 2.65; tail 2.80; tarsus 0.80. (De- 

 scribed from Mexican specimens.) Mexico to the Valley of the Lower Rio Grande in Texas ;
