A peculiar Central Asiatic species, of which the affinities are by no means clearly ascertained, is the type of the present genus. It has been referred by Jerdon and others to the neighbourhood or the Curlews, and has been associated by Seebohm with the Oyster-catchers. I do not think it is allied to the former, but it may have some relationship to Haematopus.
The bill is hard, long, slender, and curved downwards; the nostril is linear, near the base of the bill and situated in a groove that extends more than half the length of the mandible. The first three quills are subequal, the 1st generally a little the longest; tail rather short. Tarsi short, stout, reticulated throughout; there is no hind toe, the middle and outer toes are connected by a web, but there is scarcely any between the middle and inner toes.
