having the tail less than \ the length of the wing, whereas in Buteo it is more 

 than I of the latter; the tarsus about § the length of the tail (instead 

 of much less), also 2§, or more, times the exposed culmen with cere 

 (instead of 2\ times or less); wing about A\ times the length of the tarsus 

 (instead of oh times or more); and the primaries exceeding secondaries by 

 nearly the length of the tail (instead of, as in Buteo, by not over f of its 

 length). 



Mr. Charles Chubb (Birds Brit. Guiana, I, 1916, p. 231) has recognized 

 this genus, but into it puts also Buteo abbreviatus Cabanis. The latter 

 action, however, is doubtless an inadvertence, since this species is abso- 

 lutely congeneric with the type and other species of the genus Buteo. The 

 forms of this genus, T achy trior chis, are as follows: 



T achy trior chis albicaudatus albicaudatus (Vieillot). 



Tachyfriorchis albicaudatus exiguus Chapman. 



Tachyfriorchis albicaudatus colonus (Berlepsch). 



Tachyfriorchis albicaudatus sennetti (Allen).

A Flight of Broad-winged Hawks and Roughlegs in Lake Co., 

 Ohio. — While seated by a country roadside, overlooking some low mead- 

 ows on April 27 of this year, four medium-sized hawks came low and 

 directly over my head. Hastily turning my glass upon them, I secured 

 enough field marks to pronounce them Broadwings (Buteo plat ypterus) . As 

 I followed them with the glass their number suddenly increased to eight, 

 and then, as I swept the sky, it seemed to be alive with them and I counted 

 twenty-five after some had vanished in the distance. Realizing I was at 

 last witnessing a hawk flight I kept a good watch and within a short period 

 of time saw nearly a hundred. Soon after the first bunch of Broadwings 

 had passed came some larger birds, singly, or at most by twos, flying high 

 and far apart. When one was directly overhead another would be seen 

 coming in the distance. Their identity puzzled me at first, until finally 

 one came comparatively low, and the black belly band of a Roughleg 

 (Archibuteo lagopus sancti-johannis) was plainly discernible. Among these 

 large hawks was a single Osprey. All the Roughlegs were sailing with 

 the wind and flying a straight northeasterly course, while the Broadwings 

 kept in bunches and circled about to some extent while still progressing 

 steadily in the same direction. The day was clear, with a fresh wind blowing 

 steadily. The most interesting fact to me was the late date the Roughlegs 

 were leaving the country and the number of them — some twenty all told — 

 and I have reason to believe I missed a good many by not being farther 

 along the road, where I could also have seen across the wide valley of the 

 river back of my position. As to all of the large hawks being Roughlegs, 

 I think there is no question, since all were of the same size and silhouette, 

 and the one which came low was easily identified. And I know the Eagle, 

 Redtail and Red-shouldered, too well to have confounded them. A num- 

 ber of Roughlegs were resident here through the winter. — E. A Doolittle,
