Supercilia and sides of head and of neck white, with brown streaks; lores and ear-coverts brown; hind neck, back, and scapulars light greyish brown, with broad dark shaft-stripes ; crown similar, but more rufous ; wing-coverts and tertiaries dark brown with whitish edges ; greater coverts white-tipped; primaries and secondaries dark brown, later secondaries edged with white near their tips ; lower back, rump, middle and upper tail-coverts, and median rectrices blackish brown, outer rectrices lighter brown ; all tail-feathers with whitish edges ; chin, throat, and abdomen white ; fore neck and breast pale brownish grey, with small dark streaks : lower and lateral upper tail-coverts and lower flanks white, with blackish shaft-stripes.
In summer the feathers of the crown, hind neck, and back, with the scapulars and some tertiaries, are black with dull rufous edges, and the upper breast is slightly tinged with rufous; the dark spots on the breast are broader and often take the form of angulate bars, extending to the flanks.

Distribution. This bird, a near ally of the American Pectoral Sandpiper, T. maculata, breeds in North-eastern Siberia and Alaska, and migrates by China and Japan to the Malayan Archipelago, Australia, and New Zealand. A single specimen was shot by Biddulph at Gilgit, flying about with a number of Pavoncella pugnax, on August 1st.
