male, differs further from him in wanting the spurs and pendulous wattles, in having the frontal papilla much smaller, the naked space of the neck less, and the colours much duller, although similar in distribution. The naked parts of the head and neck are more furnished with bristly feathers, and are of a light blue colour, with reddish tints interspersed. The bill, the eyes, and the feet, are of the same colour as in the male, the latter considerably paler. There is a line of short bristly dark-coloured feathers down the back of the neck. The general colour of the upper and under parts is greyish-brown, with metallic bronzed reflections, each feather terminated by a band of black. On the lower back the brown tints become brighter, and on the rump and upper tail-coverts change into bright chestnut, with transverse bands of brown. The ground colour of the tail is pale yellowish-brown, transversely barred and mottled as in the male, and with a broad subterminal band of brownish-black, beyond which the feathers are mottled, and finally terminated by uniform light brown. The abdominal region is dull brownish-grey. The primary quills are greyish-white, barred with brownish-black; the secondaries brownish-grey, similarly barred. The wing-coverts are similar to the feathers of the back.
