FALCONIDA — BUTEONINA: BUZZARDS. 543 
very fine zig-zag or broken blackish cross-lines. Upper parts (excepting the rump, which is 
white like the tail), definitely including the sides of the head and neck, ash-evlor or plumbeous, 
lighter or darker in different cases, the feathers fleecy-white at bases so extensively as to show 
with the least disturbance of the plumage, and on the scapulars tinged with reddish. Most of 
the lesser wing-coverts (but not quite to the bend of the wing), chestnut, somewhat as in 
B. unicinctus. Entire under parts pure white, lightly touched with fine dusky cross-bars on 
the sides, lining of wings, and usually the tibie. On the surface of the wings the plumbeous 
of the upper parts deepens to the blackish of the primaries, whose inner webs are lighter and 
more brownish, crossed with numerous darker bars, and toward the base are cut, barred, or 
speckled with white, which increases in regularity, firmness, and extent on the secondaries. 
Shafts of wing-feathers brown or black, those of tail white along the white portion of the tail- 
feathers. Bill mostly dark, in part light; feet yellow; claws black. Length of ¢ 23.00; 
extent 48.00: wing 16.00; tail 7.00; chord of culmen, including cere, 1.40; tarsus about 3.25; 
feathered about 1.00 down in front. @ larger; length 24.00; extent 54.00; wing 17.50; tail 
8.00, ete. (Described from Sennett’s and Merrill’s Texas specimens. Young unknown to 
me.) A fine large hawk of the warmer parts of America, lately ascertained to reach the 
Rio Grande of Texas; it is very unlike any other of this country. 
B. coo'peri? (To Dr. J. G. Cooper.) Cooprr’s Buzzarp = Archibuteo ferrugineus? “ Head, 
neck, and whole lower parts white; feathers of the head and neck with medial longitudinal 
streaks of black, the white prevailing on the occiput and superciliary region, the black pre- 
dominating over the cheeks, forming a ‘“‘mustache;” throat with fine lanceolate blackish 
streaks ; sides of the breast with broader, more cuneate markings of the same; flanks with 
narrow, lanceolate stripes, these extending sparsely across the abdomen; tibiee and lower tail- 
coverts immaculate, the inner face of the former with faint specks. Upper plumage in general 
dark plumbeous-brown, inclining to black on the back; plumbeous clearest on primaries, 
which are uniformly of this color, the inner ones inclining to fine cinereous. Scapulars and 
wing-coverts spattered with white beneath the surface. Rump black; upper tail-coverts 
white, tinged with rufous, and with irregular, distant, transverse bars of blackish. Tail with 
light rufous prevailing, but this broken up by longitudinal daubs and washes of cinereous, 
and darker mottlings running longitudinally on both webs; basally, the ground-color 
approaches white; tips white, with a distinct but very irregular subterminal bar of black, into 
which the longitudinal mottlings melt; outer webs of lateral feathers entirely cinereous, and 
without the black band. Under side of the wing white, with a large black space on the lining 
near the edge; under surfaces of primaries white anterior to their emargination, finely mottled ' 
with ashy and with indistinct transverse bands terminally. 4th quill longest; 3d shorter than 
5th; 2d equal to6th; Ist equal to]0th. Wing 15.75; tail 9.10; tarsus 3.25; middle toe 1.70.” 
Santa Clara Co., Cala., one specimen known, probably the last as well as the first; for I 
suppose this to be Archibuteo ferrugineus (with or without a mésalliance of Buteo borealis), 
with abnormally denuded tarsi. I have carefully examined the type specimen, but copy Mr. 
Ridgway’s description in preference to constructing a new one. 
B. har/lani. (To Dr. R. Harlan.) Harvan’s Buzzarp. ‘BLACK Warrior.” “Form 
strong and heavy, like B. borealis, but still more robust; tibial plumes unusually developed, 
long and lovse, their ends reaching to or beyond the base of the toes; lateral toes nearly equal. 
Four outer primaries with inner webs cut. Wing 14.25-15.75; tail 8.80-10.00; culmen 1.00; 
tarsus 2.75-3.25 ; middle toe 1.50-1.70. Nearly uniform black, varying from a sooty to a 
carbonaceous tint, with more or less of concealed pure white. Adult: Tail confusedly mottled 
longitudinally with grayish, dusky, and white, often tinged or mixed with rufous, the different 
shades varying in relative amount in different individuals; a subterminal band of black. 
Young: Tail grayish-brown, crossed by about 9 very regular and sharply defined broad bands of 
black about equal in width to the gray ones.” (Ridgway.) La. and Tex. to Kas. ; an obscure
