Var. Arizon£ Covurs,n.v. Like an immature S. socialis. Paler than this species, 
the ashiness in great measure brown; crown grayish-brown streaked with dusky 
like the back, and showing evident traces of rich chestnut, but never becoming 
wholly chestnut ; black frontlet lacking, and no definite ashy 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 remarkably like pallida var. brewerii, but this last is evidently smaller, without 
chestnut on the head, and otherwise different. 
Field Sparrow. Bill pale reddish; feet very pale; crown dull chestnut ; 
no decided black or whitish 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 markings ; all the ashy parts of socialis replaced by 
pale brownish. Back bright bay, with black streaks and some pale flaxen 
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. Wus., ii, 121, pl. 16, f. 2;

** Western species, with the crown not chestnut, and streaked like the back. 
Clay-colored Sparrow. Crown and back clay-colored or flaxen, distinctly 
streaked with black, without evident bay, the dorsal streaks noticeably 
separated from those of the crown, by an ashier, less streaked, cervical 
interval; rump brownish-gray. Crown divided by a pale median stripe; a 
distinct whitish superciliary line ;‘ loral and auricular regions decidedly 
brown; wing coverts and inner secondaries variegated like the back. 
Below, white, soiled with clay-color. Bill and feet pale. Small; 43-54; 
wing and tail, each, 24. Central region of the United States into British 
America. Emberiza pallida, Swatnson, Fauna Bor.-Am. ii, 251; #. shat-

Var. BREWER. Similar; paler and duller, all the markings 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 22 long, thus equalling;if it does not some- 
what exceed, that of soctalis, although the latter is a larger bird. It bears an 
extraordinary resemblance to the curious western variety of socialis, above des- 
cribed ; but in this, as in typical socialis, the tail is appreciably shorter than the 
wings. Southwestern U. S. Emberiza pallida Aup., iii, 71, pl. 161. S. breweri

*** Western species, with the crown of the adult dark ash. 
" Black-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 full 6 long, on account of the great length of
