Female. Upper plumage dull buff, streaked with marks of dark brown, on the hind-neck these increase to blotches and on the back and other parts become broad bars ; scapulars, inner secondaries, lesser and median coverts like the back but the feathers broadly tipped with buff and some of the coverts finely edged with brown"; sides of head, neck and breast more vinous and strongly spotted with black; lower breast dull pale ochre-buff; abdomen, flanks and vent rufous-buff closely barred with very dark brown; under tail-coverts creamy-buff.

Nestling in down. Above pale ginger broken by white patterns and lines, pricked out in black; underparts isabelline-white, darkest on the throat; the pattern on the head and on the back assumes the shape of a figure of eight.

Distribution. South Arabia, South and South-West Palestine to Baluchistan and India. In our own area it occurs practically everywhere in the plains where the rainfall is not too heavy. It does not occur in Ceylon but is found in the open parts of Travancore, whilst Blanford shot them near Trichinopoly. East it is found as far as Raneegange and Birbhum. It is common in parts of Sind and in the Punjab and has been killed in Kashmir.

Nidification. This Sand-Grouse breeds wherever there are suitable areas or open waste, desert country, fields with stubble, or fields lying fallow. Eggs have been taken in every month of the year, except perhaps August, but the principal months are March to May in the North and possibly January to March in the Bombay Presidency and the Southern Provinces. Most birds breed twice in the year at least. The eggs, normally three, are laid in slight hollows scratched by the birds, without lining and, generally, with no shadow protection by stone, clod or vegetation. Both parents incubate and during the hot hours of the day the eggs are never left uncovered. In colour they are pale grey-stone or yellowish-stone with numerous small blotches and spots of various shades of brown profusely scattered over the whole surface and with secondary markings of lavender and grey. In a few eggs the underlying grey spots predominate. Two hundred eggs average 36.8 x 26.2 mm.: maxima 40.5 x 26.1 and 34.1 x 28.2 mm.; minima 32.9 x 24.9 and 34.1 x 23.2 mm.

Habits. This Sand-Grouse is very common wherever the country is open, whether it is absolute desert or only semi-desert mixed with cultivated land. It drinks early in the morning, about two hours after dawn, and again early in the evening before sunset. Unless much shot over they are not wild birds, but big docks (they run up to 200) can seldom be approached near enough for a shot and most sport is obtained as the birds flight to and from their drinking - places. Huge bags are some¬times obtained in this nay and, as the birds are very powerful on the wing and have very dense plumage, it takes straight shooting to drop them. They feed on seeds, grain and vegetable shoots and, though dry, are good birds for the table.

* Pterocles senegalensis of Licht., 1823 (Verz. Doubl. p. 64) is preoccupied by senegalensis Shaw & Modder, 1814. We must therefore once more revert co exustus as the specific name.
