When this Pigeon does rise, it flies with extreme rapidity, making a loud burring noise with the wings, and generally spinning off to another part of the plain, or to the horizontal branch of a tree, on which it immediately squats in the same line as the branch, from which it is not easily distinguished or driven off. The two eggs are placed on the bare ground without any trace of nest. The nestlings run and fly when only the size of a Quail. The food of this bird principally consists of seeds of grasses and small plants, and in some seasons insects and berries. Water seems quite an essential to its existence; and many writers inform us that it is abundant on such plains as are intersected by rivers and water-holes. Gould met with this bird on the Liverpool Plains, and as he proceeded on the Lower Namoi its numbers seemed to increase; it is said to be equally abundant on the banks of all rivers between New South Wales and the Murray, in South Australia. Mr. Gould has never observed it in collections from the northern or western parts of that continent; thus it would appear to be limited to the south and east. * * * * * The WHITE-FLESHED PIGEONS (_Leucosarcia_) are recognisable by their powerful, compact build; long, round beak; short, shell-shaped wings; moderate-sized, rounded tail, and very long tarsi. THE WONGA-WONGA PIGEON. The WONGA-WONGA PIGEON (_Leucosarcia picata_) is of a greyish hue on the mantle, and white on the brow, throat, and under side. The sides of the head are light grey; the bridles, a triangular patch and two broad lines on the upper part of the head are black; the feathers on the sides of the belly are decorated with dark, triangular, metallic spots; the anterior wing-feathers are brown, the outer tail-feathers white at the tip, and the feathers of the lower tail-covers dark brown, becoming lighter towards their tips; the eye is dark brown, the beak purplish black, and the foot of a reddish shade. The length of this species is fifteen inches; the wing measures seven inches and a half, and the tail five inches and a quarter. The Wonga-wonga Pigeon is an inhabitant of Australia, where, however, seeing its value as an article of food, it is by no means so plentiful as could be wished.
