A broad band between the eyes, continuous with a streak over them, a small band on the lower eyelid, and a ring on the middle of the neck, enlarged in front so as to cover the throat, pure white. A broad ring of black on the lower part of the neck, broader in front. All the lower parts and the sides of the rump white.

Alula, primary coverts, and primary quills dusky, the coverts tipped with white, the outer primaries, with a portion of the shaft white, the inner with an elongated patch of white on the outer web in addition, and the proximal part of the inner web of the same colour. Secondary quills with a narrow terminal margin of white, which is much enlarged on (or in some specimens covers) the two next to the elongated ones, which are externally margined with brownish-white. Tail pale greyish-brown, brownish black towards the end, the tip white, enlarging on the outer, and including the whole of the lateral feather, and the outer web of the next. Length to end of tail 7-1/4 inches, to end of wings 8, to end of claws 7; extent of wings 14; bill along the ridge 1/2, along the edge of lower mandible 7/12; wing from flexure 5, tail 2-1/2; tarsus 11/12, middle toe and claw 10/12.

Bill dusky, at the base yellowish. Feet pale yellowish-green, claws dusky. Upper parts lighter than in the adult, the feathers margined with pale yellowish-grey; no black band on the forehead, or on the neck, but a patch of dusky on the side of the neck and breast; the band from the bill to behind the eye greyish-brown. This species exhibits a very intimate affinity to _Charadrius Hiaticula_ of Europe, which is precisely similar in form, proportions, and colouring, but considerably larger, and having the feet orange-coloured, with the webs much less extended.
