able by the hoary gray tail, darker toward the end, with nmneroiis obsolete dark bars, and 

 whitish or buff tip. Nestlings covered with sooty brown down, quite blackish on the head, 

 lighter on posterior upper parts, buffy white below. A tiiu! large Hawk of the warmer parts 

 of America, N. to Texas, and also known to breed in southern Arizona (Auk, Oct. 1899, 

 p. 352, and Oct. 1897, p. 403). It is very unlike any other of this country. It abounds in 

 the lower parts of Te.xas, where it breeds from February to July indifferently, placing the large 

 bulky nest of sticks and grasses on low trees and bushes ; eggs 2 or 3, about 2.35 X 1-90, dull 

 white, immaculate, or only very lightly marked with pale brownish and neutral lint, and thus 

 differing from ordinary Buzzard eggs; they are also large for the size of the bird. B. albocau- 

 datiis of 2d-4th eds. of the Key, p. 542; B. alhiccmdatm A. O. U. List, 1st ed. 1886; B. ulhi- 

 caudatns sennetti Allen, Bull. Amer. Mus. Nat. Hist, v, 1893, p. 144 ; A. 0. U. List, 2d ed. 

 1895, No. 341. The species is type of tlie subgenus Tuclujtriorohis Kaup, 1844; but it is an 

 oversight in the arrangement of tlie A. 0. U. List to bring B. swainsoni and B. latissimus under 

 this subgenus, as they belong to Buteo jiroper. Sharjie raises Tachytriorchis to full generic 

 rank, and restricts it to alhocaudatiis and abbreviatus, in Cat. B. Brit. Mus. i, 1874, p. 101. 



(Subgenus lirxEO.) 



? B. buteo. CojiMOX EuROPEAX Buzzard. Puttock. Type of this subgenus, as of the 

 whole genus. A large species, having 4 primaries emarginate on the inner web, as in our 

 B. borealis but in plumage e.xtremely variable, most resembling B. sicainsoni as described 

 beyond, and sometimes almost identical in coloration with one of the dark ])hases of the latter. 

 Wing 15.50-ltJ.50 ; tail 8.00-9.00. Europe, etc. Said to have occurred once in Michigan. 

 We have the specimen, unquestionably of tliis species, but the alleged occurrence is open to 

 doubt. See the case as set forth at Icngtli iu Bull. Nutt. Orn. Club, i, iS7G, \^\>. 4-<i, and 

 pp. 32-39. (Not heretofore allowed in tlie Key. A. O. U. No. [.33fi.].) 

 B. coo'peri? (To Dr. J. G. Cooper.) Cooper's JiuzzAiiu =s: Archibutco ferrugineus ? 

 Head, neck, and whole lower parts white; feathers of head and neck with medial longitudinal 

 streaks of black, the white prevailing on occiput and superciliary region, the black predomi- 

 nating over cheeks, forming a mustache; throat with fine lanceidate blackish streaks; sides 

 of breast with broader, more cuneate markings of the same ; flanks with narrow, lanceidate 

 stripes, these extending sparsely across abdomen ; tibife and lower tail-coverts immaculate, 

 inner face of the former with faint specks. Upper plumage in general dark plumbeous-brown, 

 inclining to black on back ; jjhunbeous clearest on primaries, whicli are uniformly of this 

 color, the inner ones inclining to fine cinereous. Scapulars and wing-coverts spattered with 

 white beneath the surface. Rump black ; uj»))er tail-coverts white, tinged with rufous, and 

 witli irregular, distant, transverse bars of blackish. Tail witli light rufous prevailing, but 

 this broken up by longitudinal daubs and washes of cinereous, and darker mottlings running 

 Inngitiidinally on both webs; basally, the ground-color approaches white; tip wiiiti', with a 

 di.stinct but very irregular subterminal bar of black, into which the longitudinal mottlings 

 melt; outer webs of lateral feathers entirely cinereous, and without the bhick band. T'nder 

 side of wing white, with a large black space on lining near edge ; under surfaces of ])rimaries 

 white anterior to their emargination, finely mottled with ashy atul with indistinct transverse 

 liands terminally. 4th quill longest; 3d shorter than 5th; 2d equal to (ith; 1st er|ual to 10th. 

 Wiiiir 15.75; tail 9 10; tarsus 3.25; middle toe 1.70. Santa Clara Co., California, one sp«ri- 

 nien known, ))nd)ably the last as well as the first; for I suppose tliis to be ArchibuU-o fcniigi- 

 veus (witli or without a mdaaUiaticc of Buteo borealis), with aluiormally ilemnled tar.^i. I have 

 carefully examined the type specimen, but condense Mr. Kidirway's description iu preference to 

 constructiiiiT a new one. (No new light has been thrown mi the case since tlie above wiia
