Smallest Waders with short straight slender bills, long wings, comparatively 
long tails, short legs, and short feet. The culmen is short, straight, and slender, 
with the groove in the upper mandible extending almost to the tip : the 
tip is somewhat expanded and faintly punctulate. The culmen is shorter 
than the metatarsus, and less than half the length of the tail. 
The wings are long and pointed with the first primary longest. The tail, 
which is strongly doubly emarginate, is less than half the length of the wing 
but more than one- third, and is twice the length of the culmen. The 
metatarsus is short, regularly scutellate both in front and behind, longer 
than the culmen and also the middle toe. The toes are all cleft to the base 
and a hind toe is present. 
The bird described bv Horsfield as Totanus datnacensis differs from the 
preceding in its longer legs and especially longer toes and claws. The hind 
toe and claw is also very long. The metatarsus is more than a fourth the 
length of the wing, and the middle toe is longer than the culmen : in 
typical members of the genus Pisobia the metatarsus is less than one-fourth 
the wing and the middle toe is shorter than the cuhnen. These differences 
seem to constitute a subgenerio distinction that may be emphasized by the 
new subgeneric name of NE0PI80BIA,
