Syn. Cinclidium, olim, Blyth.

Char. - Bill shorter than the head, straight, slender, higher than broad, with the ridge acute; lower gonys ascending; nares partially impended by some short half- reflected feathers; gape with  a few small setae; wings and tail rounded; the 4th, 5th, and 6th quills equal and longest; legs and feet slender; tarsus long; middle toe long ; claws not much curved.
