This lapwing resembles a large plover, but is distinguished by

having a small hind toe, a short and blunt wing-spur, and a small,

fleshy wattle or lappet between the eye and the base of bill. The

only Philippine specimen known was taken near Manila in January, 1906.

Bill moderate, not longer than head, culmen flat and straight from

base to the terminal swollen dertrum; first primary slightly the
