Adult female.--Above reddish brown, slightly shaded with olive; top and sides of head, hind neck, sides of neck, and mantle lighter, pale reddish, and narrowly banded; on lower back and rump the bands inconspicuous so that these parts appear nearly uniform; chin light; throat-feathers light fawn-color with dark shaft-stripes, ground color of chest and belly bright red-brown, with narrow blackish stripes; bend of wing white; scapulars and greater wing-coverts with some larger opaque white spots on outer webs; primaries with inner webs uniform black, outer webs with broad dark brown and smaller pale reddish band spots; on the tertials appear very inconspicuous, broad, darker bands, and on the whole length of the edges of the outer webs, pale fawn spots; tail-feathers with darker brownish bands of equal width; under tail-coverts light fawn; inner wing-coverts light reddish brown with darker spots. Legs light yellowish; iris yellow. Length, 250; wing, 169; tail, 80. Male.--Differs only in the following that the bands on the lower belly and thighs are on a lighter background; and the reddish brown ground-color of chest and epigastrium is somewhat lighter. Wing, 168; tail, 80. Another female.--The brownish red of abdomen very fiery with irregular and less distinct bands. Wing, 168 mm.; tail, 78. [33] I doubt very much if this species is really distinct from Ninox mindorensis; the size is nearly the same and specimens of the two do not seem to have been actually compared. Subfamily STRIGINÆ.
