In Hobart Town it is frequently exposed for sale in the markets with Bronzewing Pigeons and Wattle-birds, where it is known by the name of Ground-Dove, an appellation which has doubtless been given both from its habit of running and feeding upon the ground like the Pigeons, and the circumstance of its flesh being very delicate eating; to its excellence in this respect I can bear testimony. The pectoral muscles are very largely developed, and the body, when plucked, has much the contour of a Quail. The duty of incubation is performed in October and the three following months, during which period two and often three broods are produced. The nest is a slight and rather careless structure, composed of leaves and the inner bark of trees, and is of a round open form; it is always placed on the ground, under the shelter of a large stone, stump of a tree, or a tuft of grass. The eggs are two, and sometimes three, in number, one inch and three lines long, and are white, blotched with large marks of olive-brown, particularly at the larger end, some of the spots appearing as if on the inner surface of the shell. The young, which at two days old are thickly clothed with long black down, like the young of the genus _Rallus_, soon acquire the power of running, and at an early age assume the plumage of the adult, after which they are subject to no periodical change in their appearance. The stomach is very muscular, and in those dissected were found the remains of seeds and caterpillars mingled with sand. Adult males have the forehead and chest ash-grey; crown of the head, back, rump, and the middle tail-feathers rufous brown, each feather of the back having a broad longitudinal stripe of black down the centre; shoulders and wing-coverts steel-black, each feather having a spot of white at the extreme tip; primaries blackish brown, margined on their outer edges with lighter brown; throat and a narrow band across the chest steel-black; stripe over the eye, a nearly circular spot on the side of the neck, and the centre of the abdomen white; flanks and under tail-coverts reddish buff, with a large oblong stripe of black down the centre of each feather; lateral tail-feathers black, broadly margined with grey on their inner webs, and largely tipped with white; bill black; legs fleshy-white; feet darker; eyes very dark lead-colour, with a naked blackish brown eyelash. The female differs from the male in having all the upper surface of a lighter hue; the throat greyish white instead of black; the spot on the neck rufous instead of white, and in being destitute of the black pectoral band. The figures are of the natural size. [Illustration: CINCLOSOMA CASTANOTUS: _Gould_. _J. & E. Gould del et lith._ _C. Hullmandel Imp._ ] CINCLOSOMA CASTANOTUS, _Gould_.
