NINOX. 267 
quills like tail but spotted, instead of barred, with light rufous- 
brown; scapulars like back, some of them with large nearly white spots 
on outer webs; a few of greater series of wing-coverts also spotted with 
white on outer webs; chin and throat whitish, almost pure white in one 
specimen, in others light rufous-brown, the feathers always with black 
shaft-stripes ; auriculars fulvous-brown somewhat mixed with light rufous- 
brown; sides of neck like head; breast, abdomen, flanks, thighs, under 
wing-coverts, and axillars rufous-brown, the depth of the color subject to 
great individual variation, many feathers of breast and abdomen with 
fulvous-brown spots and all with blackish bases; under surface of wing 
fulvous-brown. Inner webs of feathers, especially of secondaries, spotted 
and barred with light rufous-brown; a spot of white on bend of wing; 
tarsus feathered for rather more than half its length. Iris yellow; legs 
and feet pale yellow; bill black at tip, gray at base. Two females measure, 
241 in length; culmen, 13; tarsus, 31; wing, 181; tail, 102. 
“A single specimen of this species was secured in Cebu by Mr. Worcester 
in 1888. Its curious mottled back and under surface were suggestive of 
immaturity, and Dr. Steere thought it to be the young of some undescribed 
species. We have altogether too much material now to make such a 
theory tenable.” (Bourns and Worcester.) 
A rusty brown male was taken in Sibuyan. Iris yellow; bill and legs 
pale dirty greenish; cere a little darker; nails gray, blackish at tips. 
Length, 285; wing, 210; tail, 114; culmen from base, 23; tarsus, 32. 
A male from Cebu is in the light phase. Chin, throat, and forehead 
mostly white; rictal bristles with white bases; scapulars spotted with 
white; abdomen and flanks very largely white and with no fulvous nor 
rusty brown wash.

Diagnosis.—Distinguished at once from the common species (Ninox 
philippensis) by its greater length (290 mm.), by its much longer wings 
passing even the tip of the tail, and finally by its reddish brown plumage 
and transverse brown bars on head and on shoulders.* 
*“Quant a la Chonette qui provient du meme [Sulu] archipel, on peut la 
distinguer immediatemen de l’espéce commune des Philippines (Ninox philippensis ) 
par sa taille plus forte (o m. 29), par ses ailes beaucoup plus longues et depassant 
méme l’extrémité de la quene, et enfin par son plumage roux, rayé transversale- 
ment de brun sur la tete et sur les épaules. Par ce dernier caractére, la chouette 
des iles Sooloo, que pourra étre appelée Ninow Reyi, ressemble en peu au Glaucidium 
ou Athene cuculoides de l’Indo-Chine, espéce dont les ailes sont, du reste, beaucoup 
moins developpées.” (Oustalet.)
