large for the size of the bird, of a dullish-white colour, strongly granulated, and consequently rough to the touch. It was on discovering one of these nests that I wounded the second adult male which I have seen, but which never returned to its nest, on which I afterwards shot the female represented in the Plate, in the act of pouncing. I have several times found other nests of birds of this species, but the owners were not in full plumage, and their eyes had not obtained the rich orange colouring of the adult birds.

Those which I have observed near the Falls of Niagara were generally engaged in pursuing Red-winged Starlings, over the marshes of the neighbourhood. When this Hawk is angry, it raises the feathers of the upper part of the head, so as to make them appear partially tufted. The cry at this time may be represented by the syllable kee, kee, kee, repeated eight or ten times in rapid succession, and much resembling that of the Pigeon Hawk (Falco columbarius) or the European Kestril. The young of this species bear no resemblance to those of the Goshawk, of which a figure will be given in the same Plate with the adult of the Stanley Hawk.

Stanley Hawk, Falco Stanleii.

Adult Male.

Bill short, robust, cerate; upper mandible with the dorsal outline curved from the base, the back rounded, the sides sloping at the base, convex toward the end, the margin sharp, overlapping, having an obtuse lobe, the tip trigonal, very acute, and curved downwards; lower mandible broadly rounded on the back, convex on the sides, acute in the edges, somewhat abrupt at the end. Nostrils oval, oblique, in the fore-part of the cere. Head rather large, flat above; eyebrow acute and projecting. Neck strong. Body rather elongated. Legs long; tarsi rather long, and with the toes somewhat slender, the former scutellate anteriorly, the latter scutellate above, papillar and tuberculate beneath; claws long, curved, roundish, rather slender, and extremely acute.

Plumage compact, imbricated, glossy. Space between the beak and eye sparsely covered with bristly feathers. Tibial feathers rather compact, and not much elongated. Wings long: fifth quill longest, sixth and fourth nearly equal, first very short. Tail long, straight, a little rounded, of twelve rather broad feathers.

Bill light blue at the base, black at the tip. Cere greenish-yellow. Iris reddish-orange. Tarsus and toes bright yellow; claws brownish-
