"Adult.--Above ashy brown, with dusky shaft-lines; scapulars like back; upper tail-coverts ashy like back, but freckled and barred with dusky brown; lesser wing-coverts dark brown, lower ones blackish at the ends and forming a broad band across wing, followed by another band of white, formed by median coverts, which are gray at the tips, with a broad white band across the middle followed by another bar of dusky blackish; greater coverts entirely gray, fading off into whitish at the ends; alula and primary-coverts white like the quills they cover; primaries brownish black with white along inner web, extending across outer web of the first two; inner primaries pure white; secondaries dark brown, externally gray, with white bases and small white tips, also white along the inner webs; on the inner secondaries the white confined to inner web, long innermost secondaries ashy brown like back; tail ashy brown, with a black band at the end, before this a broad white band, preceded by a narrow black band; two middle feathers light ashy brown freckled with dusky mottlings, the other feathers also slightly freckled with dusky; crown and neck like the back; lores blackish, as also a broad band along the sides of crown, extending to the sides of the neck, where it joins the black ear-coverts and incloses the white of face, which consists of a white band above and below the eye extending above the ear-coverts; cheeks white, extending in a line along base of upper mandible and forming a streak in front of eye; fore part of cheeks black; chin and throat white; lower throat ashy brown, streaked with darker brown, as also the sides of neck; breast pale ashy; remainder of the under surface white with a slight tawny tinge; under tail-coverts tawny-buff; under wing-coverts and axillars white. 'Base of bill sulphur-yellow, continued along the sides of upper mandible above nostrils; remainder of bill black; tibia lemon-yellow; tarsi and feet wine-yellow; upper ridges of scales of toes lead-color; eyelids primrose-yellow; iris pale yellow.'

"Young.--Two specimens from the Duke of York Island and Guadaleanar are apparently immature, having the feathers of the upper surface tipped with sandy buff, especially on the wing-coverts, where the white band on the median series is not so defined as in the adults, but showing a broader band of brown-tipped feathers below. There is, however, a second white band formed by the white tips to the greater wing-coverts, and it is somewhat curious that this should be a sign of immaturity." (Sharpe.) The stone plover is remarkable for its large and powerful bill. It is rare in the Philippine Islands and so far as observed it is found on sea-beaches where it subsists upon sand-crabs.
