“Much like P. affinis of Mindanao, but differs from it in having the rufous upon the tail reaching to and beneath the upper tail-coverts, so that the whole base of the tail appears rufous, though some specimens show some black at the bases of the feathers when they are uncovered. The sides of the mandible are also flesh-colored to their bases instead of being black behind as in P. affinis.” (Steere.)
“The differences enumerated by Steere between this species and P. affinis, though slight, occur in all the specimens secured by us. A male measured, 610 in length; wing, 231; tail, 205; tarsus, 45; middle toe with claw, 46. A female, length, 559; wing, 211; tail, 183; tarsus, 39; middle toe with claw, 45. Eyes red to umber-brown; legs and feet greenish slate-color; nails black; bill white at tip, black on crest, remainder mottled with reddish brown.” (Bourns and Worcester MS.)
