H. carpa'lis. (Lat. carpalis, relating to carpus, wrist-joint.) Bay-winged Summer Finch. 

 Adult ^ 9 : Lesser wing-coverts chestnut, forming a patch as conspicuous as in Pocecetes or 

 Auripurus. Strong black maxillary stripes. Whole crown rufous, or dull bay, divided on 

 forehead by a short pale stripe, and bordered with a pale grayish-ash superciliary stripe. 

 Cervix like crown, but mixed with ashy-gray. Middle of back and scapulars grayish- brown, 

 mixed with a little bay, and sharply streaked with blackish; lower back gray, with little or 

 no black or brown. The general effect of the upper parts, crown, aud back is like that of 

 Spizella socialis. Wings and their greater coverts dusky, with grayish-fulvous edging and 

 tipping ; primaries and tail-feathers with whitish edging ; one or two outer tail-feathers white- 

 tipped. Under parts white, shaded on breast and sides with ashy ; throat pure white, bounded 

 on «ach side by a sharp black maxillary stripe, above which is another dark line from angle of 

 mouth. Bill apparently reddish tlesh color below, dusky above; feet pale brown, toes rather 

 darker. Length about 6.00 ; extent 8.50 ; wing 2.25-2.50 ; tail 2.75, graduated about 0.50 ; 

 bill 0.40 ; tarsus 0.67. Less mature : Crown less different from back, being streaked with ashy, 

 blackish, and rufous. Very young : No chestnut on wing-coverts ; upper parts, including 

 crown, dull brownish broadly streaked with blackish ; under parts streaked with dusky ; thus 

 much like the earliest stage of Spizella socialis ; after this the chestnut bend of the wing is 

 always conspicuous. Arizona and Sonora. A very distinct and curious species, nesting in 

 bushes and laying a plain greenish egg. Eggs 4-5, 0.72 X 0.58, June-September; nest in a 

 fork of bush, deeply cupped, of grasses, rootlets, and hairs. Peuccea carpalis CouES, Am. 

 Nat. June, 1873, p. 322, and of 2d-4th eds. of Key, p. 375; A. 0. U. Lists, 1886-95, No. 579.

AMPHISPI'ZA. (Gr. a/i0i, amj)1ii, on both sides ; (nrl^a, spiza, a finch : alluding to the 

 close relation of the genus to those about it.) Sage Sparrow's. Bill moderate, conical, not 

 peculiar. Wings folding considerably beyond base of tail, without elongated inner seconda- 

 ries ; point of wing formed by 2d-5th quills, 1st between 6th and 7th. Tail nearly equal to 

 wings, of rather broad firm feathers, rounded at ends. Tarsus longer than middle toe and claw ; 

 lateral toes of unequal lengths, outer (longer) not reaching base of middle claw. Embracing 

 two Southwestern species, with rounded blackish tail, grayish-l)rown above, plumbeous-black 

 bill and feet, and few decided streaks, or none. These do not particularly resemble each other, 

 and are very different from the exotic Poospizn to which they were formerly referred. I based 

 this genus in 1874 (B. N. W. p. 234) on A. bilineata, and also included A. belli ; since then, 

 several extralimital species have been referred to it, as A. Immeralis, A. mystacalis, and 

 A. quinquestriata, whicli had before been placed in the genera Hci'inophila and Zonotrichia.
