TEINQILLIDiE, FINCHES, ETC. GEN. 73. 143 



Var. aeizoNj'e Coues, n. v. Like an immature S. socialis. Paler than tliis species, 

 the ashiness in great measure brown ; crown grayish-brown streaked witli dusky 

 like the back, and showing evident traces of rich chestnut, but never becoming 

 wholly chestnut ; black frontlet lacking, and no definite ashj^ superciliary line, the 

 sides of the crown merely lighter brown ; bill brown above, pale below. Arizona, 

 and probably other portions of the same region. A curious form, as it were an 

 arrested stage of socialis. Some specimens, with the least chestnut on the head, 

 look remarkablj' like iKilUda var. hreicerii, but this last is evidently smaller, without 

 chestnut on the head, and otherwise diiferent. 



1.^1 Field Sparrow. Bill pale reddish ; feet very pale ; crown dull chestnut ; '' 

 1 no decided black or whitisli about head. Below white, unmarked, but much 



washed with pale brown on breast and sides ; sides of the head and neck 

 with some vague brown marliings ; all the ashy parts of socialis replaced by 

 pale brownish. Back bright bay, with black streaks and some pale fiaxou 

 edgings; inner secondaries similarly variegated ; tips of median and greater 

 coverts forming decided whitish cross-bars. Size of socialis, but more 

 nearly the colors of monticola; sexes alike; young for a short time streaked 

 below, as in socialis. Eastern United States, very abundant in fields, copses 

 and hedges, in flocks when not breeding. Wils., ii, 121, pi. 16, f. 2;

** Western species, with the crown not chestnut, and streaked like the back, 

 j ft '' Clay-colored iSjxirrow. Crown and back claj'-colorcd or flaxen, distinctly 

 streaked with black, without evident baj^, the dorsal streaks noticeably 

 separated from those of the crown, by an ashicr, less streaked, cervical 

 interval ; rump brownish-gray. Crown divided by a pale median stripe ; a 

 distinct whitish superciliary line ; loral and auricuhir regions decidedly 

 brown ; wing coverts and inner secondaries variegated lilve the back. 

 Below, white, soiled with clay-color. Bill and feet pale. Small ; 4J-5:^ ; 

 wing and tail, each, 2^. Central region of the United States into British 

 America. Ember iza pallida, Swainson, Fauna Bor.-Am. ii, 251; iE. sliat- 

 ^itc/uw AuD., vii, 347, pi. 493. Bd., 474 pallida. 



^ Var. BREWEEii. Similar ; paler and duller, all the marldngs indistinct ; streaks 

 of crown and back small, numerous, not separated by a cervical interval ; no 

 definite markings on sides of head. Size of the last, but tail relatively longer, 

 rather exceeding the wings — about 2§ long, thus equalling, if it does not some- 

 what exceed, that of socialis, although the latter is a larger bird. It bears an 

 extraordinary resemblance to the curious western variety of socialis, above des- 

 cribed ; but in tliis, as in typical socialis, the tail is appreciably shorter than the 

 wings. Southwestern U. S. Emheriza pallida Aud., iii, 71, pi. IGl. S. breweri

 *** AVestern species, with the crown of the adult dark ash. 



Blaclc-chinned Sparrow. Dark ash, fading insensibly into whitish on the 

 belly, deepening to black on the face and throat; interscapulars bright bay, 

 streaked with black ; wing coverts and inner secondaries variegated with the 

 same colors ; tail blackish, with pale edgings ; bill reddish, feet dark. A 

 small species, but measuring ftdl G long, on account of the great length of
