“Discovered by us in October, 1891; it is the finest of the Philippines representatives of the genus. Found in deep forest, but especially abundant in the high mangrove trees south of Tataan. The amount of red on its head is exaggerated in the plate in The Ibis, and it is too light in color.

“Eight males from Tawi Tawi measure, 268 in length; wing, 171; tail, exclusive of racket, 90; culmen, 22; tarsus, 15; middle toe with claw, 29. Four females measure, length, 255; wing, 165; tail, 96; culmen, 21; tarsus, 16; middle toe with claw, 28. Iris varies from pale yellow to hazel; legs and feet gray; nails gray to black; bill gray to white.” (Bourns and Worcester MS.)

Luzon (Whitehead, Worcester, McGregor, Mearns.)

Male.—Forehead, lores, and face blue, bases of the feathers largely green; a large red spot on vertex, surrounded by blue; hind head, neck, and sides of neck grass-green; mantle, back, and rump duller and more yellowish green; wings, upper tail-coverts, and middle pair of rectrices grass-green; lower parts green, slightly yellowish. Iris gray; bill, legs, and nails light horn-blue. Whitehead gives the iris as “dark brown.” Length, including rackets, 305 to 317; two males measure, wing, 164 to 166; tail, without rackets, 84 to 85; culmen from cere, 20 to 21; tarsus, 15 to 16.

Female.—Much like male but red and blue of head and face replaced by dark green; a slight trace of blue on forehead and around eyes. Colors of soft parts as in the male. “Differs from the female of P. verticalis in having the head dull grass-green, the forehead, lores, sides of the crown, and feathers round the eyes being washed with blue. The under parts are like those of the male and never yellow-green as in the Sibutu female.” (Grant.) One female measures, wing, 158; tail without rackets, 83; culmen from cere, 20; tarsus, 17.

Young.—Immature birds of each sex resemble the adult female.
