FALCONIDJE — BUTEONIN^: BUZZABDS. 543 



very fine zig-zag or broken blackish cross-lines. Upper parts (excepting the rump, which is 

 white Uke the tail), definitely including the sides of the head and neck, ash-color or plumbeous, 

 lighter or darker in diiferent 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 iu 

 B. unicinctus. Entire under parts pure white, lightly touched with fine dusky cross-bars on 

 the sides, lining of wings, and usually the tibi<e. On the surface of the wings the plumbeous 

 of the upper parts deepens to the blackish of the primaries, whoso 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. 

 Sliafts of wing-feathers brown or black, those of tail white along the white portion of the taU- 

 feathers. BiU mostly dark, iu part light; feet yellow; claws black. Length of $ 23.00; 

 extent 4S.00: wing 16.00; tail 7.00; chord of culmen, including cere, I.-IO; tarsus about 3.25 ; 

 feathered about 1.00 down in front. ? larger; length 24.00; extent 51.00 ; wing 17.50; tail 

 8.00, etc. (Described from Sennett's and Merrill's Texas specimens. Young unknoA^m 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. 



514. B. coo'peri ? (To Dr. J. G. Cooper.) Cooper's Buzzaed = Archihuieo ferrugineus f " 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 blaclv pre- 

 dominating over the cheeks, forming a " mustache ;" throat with fine lanceolate blackish 

 strealvs ; sides of the breast with broader, more cuueate marldngs of the same ; flanks with 

 narrow, lanceolate stripes, these extending sparsely across the abdomen ; tibiae and lower tail- 

 coverts immaculate, the inner face of the former with faint specks. Upper plumage in general 

 dark plumbeous-l)rowu, inclining to black on the back ; plumbeous clearest on primaries, 

 which are uniformly of this color, the inner ones inclining to flue cinereous. Scapulars and 

 wing-coverts spattered with white beneath the surface. Rump black ; upper tail-coverts 

 wliite, tinged mth rufous, and with irregular, distant, transverse bars of blackish. Tail witli 

 light rufous prevailing, but this broken up by longitudinal daubs and washes of cinerenus, 

 and darker mottlings running longitudinally on both webs; basally, the ground-cdnr 

 approaclies white; tips wliite, with a distinct but very irregular subterminal bar of black, into 

 whicli 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 

 witli ashy and with indistinct transverse bands terminally, dth quill longest ; 3d shorter than 

 5th ; 2d equal to 6th ; 1st equal to 10th. 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 Arcliihuteo ferrugineus (with or without a mesalliance ui 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. 



515. B. har'lani. (To Dr. R. Harlan.) Haelan's Buzzard. "Black Warrior." "Form 

 strong and heavy, like B. borealis, but stUl more robust; tibial plumes unusually developed, 

 long and loose, 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 bauds of 

 black about equal in width to the gray ones." (Ridgway.) La. and Tex. to Kas. ; an obscure
