Small Waders with long decurved bills, long wings, short tails, short legs, and 
short toes. 
The long slender culmen is decurved, with the groove in the upper mandible 
extending almost to the tip, which is not expanded. The culmen is longer than the 
metatarsus, and almost exactly twice the length of the middle toe. The wings are 
long and pointed, the first primary longest. The tail is short, doubly emarginate 
as in Pisobia, much less than half the length of the wing and not much longer than 
the culmen. The metatarsus is short, about three-fourths the length of the culmen ; 
it is regularly scutellate, both in front and behind. The toes are all cleft to the 
base, the middle toe about two-thirds the length of the metatarsus ; a long hind- 
toe present,

An adult female collected in March is just beginning to put on the summer-

sides of the body. 
Immature —Upper-surface brown, feathers with white tips forming a scalloped
