[The male had the iris black; bill light straw-yellow ; feet darker straw-yellow. I met with it at 
about 3000 feet in the scrubby jungle on the lower spurs of Kina Balu. The female bird was obtained 
at about the same elevation and in precisely similar situations. 1 do not think it goes higher up the 
mountain. The first bird was obtained under curious circumstances. One of my hunters having found a 
flock of Staphidia everetti and other small birds in the jungle, singled out one of them and brought it 
down with a walking-stick gun. To his astonishment this large Owl came tumbling down along with the 
little Staphidia. The man had not seen the Owl in the thick jungle, and there is no doubt that the small 
birds had been mobbing it.]

Adult female. General colour above tawny rufous, mottled with coarse black vermiculations, giving 
here and there a spotted appearance ; on the hinder mantle some large ovate fulvous marks, not 
sufficiently indicated to form a “ wig ” ; scapulars externally yellowish white, forming a broad streak, 
with a black spot near the end of the shaft ; upper tail-coverts rather more regularly barred with black ; 
wing-coverts like the back, but the black vermiculations on the median series more sparsely distributed ; 
bastard-wing blackish internally, with a chequered pattern of broad black and tawny-buff bars on the 
outer webs ; primary-coverts rufous, with small black vermiculations and feebly indicated bars of black 
on the outer web ; primaries chequered with black and tawny-buff bars on the outer web, the black more 
or less mixed with tawny buff; inner webs blackish ; secondaries rufous, vermiculated with black, 
scarcely forming any bars ; tail-feathers black, with a few more or less distinct rufous bars towards the 
ends ; crown of head like the back, but rather more strongly mottled with black bars ; forehead tawny 
rufous, the frontal plumes tipped with black ; base of bill beset with long plumes, barred with rufous and 
black ; above the eye a dusky blackish spot; sides of face, ear-coverts, and cheeks rufous, barred with

upper surface, with large black spots on the recurved plumes of the upper throat ; the black vermicu¬ 
lations much more scanty than on the upper parts, with a few broad interspaces of tawny buff on some of 
the feathers, giving an appearance of light spots here and there ; abdomen whitish; sides of body and 
flanks like the breast, but with scarcely any trace of black vermiculations ; thighs tawny rufous, whitish 
behind ; under tail-coverts white, with a slight rufous tinge ; under wing-coverts tawny, with paler buff 
edges ; the edge of the wing mottled with blackish; outer coverts uniform blackish; quills below blackish ? 
barred with tawny on the outer web and with pale tawny buff along the inner webs. Total length 7 - 8

One male bird is almost of the same tawny rufous as the female described, but is a trifle darker. It 
differs in no important particulars beyond such as is usual in Scops Owls, viz. rather more or less strongly 
indicated black spots and vermiculations. The second male is much darker and browner, and has a good 
many clear indications of tawny-buff spots on the hind neck. In both males a tawny eyebrow is well 
marked. In the darker male the black markings on the throat are strongly developed, and behind the 
ear-coverts there are some whitish bars, giving a slight appearance of a ruff. The wings measure 5"2-5'3 
inches, which is about the same as in the female, but the size of the male bird is decidedly smaller. 
This little Owl, by reason of its yellow bill, comes nearest to the section of the genus Scops which
