Colour. — The tints of this bird are of a dull and somewhat sombre cast. 

 The chin, the throat, and a space round the eyes, are bare, and of a colour 

 intermediate between lake and vermilion red ; the top of the head is broccoli- 

 brown ; the upper and lateral parts of the neck umber-brown, or blackish 

 brown, with white variegations, the latter in the shape of short narrow stripes, 

 one upon the outer, and another upon the inner edge, of each feather. The 

 interscapulars, back, and shoulders, pale yellowish brown, more or less 

 glossed with grey, and each feather has a dark stripe in the course of the 

 shaft, and some fine brown undulations, or narrow oblique lines upon both 

 vanes. Under parts a rusty, or yellowish grey, the breast and lower part of 

 the neck darkest, and each feather is marked, in the course of the shaft, by a 

 dark umber-brown stripe, which increases in width towards its hinder extre- 

 mity ; in some lights many of the feathers appear distinctly margined with sil- 

 very grey : the feathers of the belly are each marked, besides, by four addi- 

 tional narrow stripes, two upon the outer edge of each vane, the outermost 

 stripe bright chesnut, the innermost yellowish white, and not always very dis- 

 tinctly defined : the feathers of the flanks, thighs, and vent, have only the 

 central brown stripe, but the vanes are finely mottled with minute brown dots, 

 or delicate undulated lines. The primary wing coverts are umber-brown ; the 

 primary and secondary quill feathers yellowish brown, the vanes of the latter 

 towards their outer edges, and most of the tertiaries dusky buff, finely mot- 

 tled, or undulated with brown. Tail dusky buff, freely variegated with ob- 

 lique, waved, narrow brown lines. Upper mandible dark horn colour ; eyes 

 dark brown ; legs, toes, spurs, and nails, greenish-brown. 



Form, &c. — Typical; bill lengthened, strong, and considerably arched, with 

 the edges of the upper mandible overlying the lower, and inclosing it. 

 Chin, throat, and space round the eyes, denuded of feathers, and slightly
