In the shortness of its bill this genus resembles Aphriza, but difiFers from it in wanting 

 the hind toe. In appearance the species of Ochthodromus are very similar to the 

 Sand-Plovers {jEgialitis), but are distinguished from the latter by their heavy bill. 



Eight species are recognized, of which two are resident in Australia and New Zealand, 

 and the other six breed in the temperate regions of the north, and migrate south in 

 winter. One of them, 0. wilsoni, is peculiar to the New ^Yorld.
