The RUFF (_Philomachus pugnax_) has a straight beak of about the same length as the head, or a little longer, and slightly depressed at its tip; the high slender feet are bare, and furnished with four toes: of these the three placed in front are connected by a skin; the hind toe is short and much raised. The moderate-sized pointed wing has the first quill longer than the rest, and the short tail is slightly rounded; the plumage is soft and thick. The male bird is about a third larger than his mate, and has during the spring his face covered with warts, and his neck adorned with a strange and beautiful collar; both these peculiarities, however, disappear towards autumn. So varied and changeful is the coloration of the plumage, that a detailed description is almost impossible. The collar above alluded to is composed of harsh feathers, about three inches long, and so wonderfully different in their hues that scarcely two males are exactly like each other; black and brown, and white feathers of various shades, spotted, striped, and marked in every conceivable way, appear indifferently on this part of the plumage. The upper wing is deep brownish grey, and the blackish grey tail is spotted with black; the belly is white, and the rest of the body very variously coloured and marked. It has, we believe, been ascertained that each male exhibits the same hues and markings every succeeding year. The eye is brown, the beak generally greenish or greenish yellow, and the foot reddish yellow. This species is from eleven inches to twelve inches and a half long, and from twenty-three inches and a half to twenty-four inches across; the wing measures from seven inches to seven inches and a half, and the tail about three inches. The plumage of the female, which does not vary as does that of her mate, is principally reddish grey, darkly spotted upon the upper portions of the body. The face and brow are light grey, the crown is grey, striped with brownish black; the nape-feathers are grey, those on the back and shoulders blackish brown, edged with rust-red. The throat and gullet are grey, and the belly-feathers of a whitish hue. The female is ten inches long, and twenty-one inches and a half broad. [Illustration: THE RUFF (_Philomachus pugnax_).
