touched with brownish ; the wings reach rather beyond the tip 
of the tail ; the five first primaries are white on their inner 
vanes ; tail, rounded at the end, deep black, crossed with five 
narrow bands of pure white, and broadly tipt with dull white ; 
vent, black, spotted with white ; inside vanes of the primaries, 
snowy ; claws, black, strong, and sharp : toes, remarkably 
short. 
I strongly suspect this bird to be of the very same species 
with the next, though both were found to be males. Although 
differing greatly in plumage, yet, in all their characteristic 
features, they strikingly resemble each other. The Chocolate- 
coloured Hawk of Pennant, and St John’s Falcon of the 
same author, (Arct. ZooL No. 93 and 94,) are doubtless 
varieties of this; and, very probably, his Rough- legged Falcon 
also. His figures, however, are bad, and ill calculated to 
exhibit the true form and appearance of the bird. 
This species is a native of North America alone. We 
have no account of its ever having been seen in any part of 
Europe ; nor have we any account of its place or manner of 
breeding.

This is probably a younger bird of the preceding species, 
being, though a male, somewhat less than its companion. 
Both were killed in the same meadow, at the same place and 
time. In form, features, and habitudes, it exactly agreed with 
the former. 
This bird measures twenty inches in length, and in extent, 
four feet; the eyes, bill, cere, toes, and claws, were as in the 
preceding; head above, white, streaked with black and light 
brown ; along the eyebrows, a black line ; cheeks, streaked like
