Otus longicornis McGREGOR and WorcESTER, Hand-List (1906), 46. 
Baig-a6, Benguet. 
Luzon (Whitehead, McGregor). 
Adult male——Upper parts bright rufous, the feathers with streaks and 
irregular bars of blackish brown, mostly near their tips; forehead, line 
over each eye, and complete collar white, the feathers blackish at their 
tips; collar narrow but distinct on hind neck, wider on breast; loral 
plumes with white bars and black tips, the longest plumes about 28 mm. ; 
ear-tufts colored like the head, longest feathers 31 .mm.; ear-coverts 
barred with white, blackish brown, and rufous; chin whitish; throat and 
sides of throat white, each feather with a black tip and subterminal 
rufous line; breast rich rufous boldy mottled with black and less white; 
abdomen, flanks, and under tail-coverts largely white, the feathers mottled 
with blackish and rusty brown; thighs rufous; wings blackish, mottled 
and speckled with fulvous and rusty brown, tail similar. Bill dingy 
dull green, tip and cutting edge dark brown; cere dirty flesh at base 
but dull yellowish green over nostrils; legs whitish flesh; nails gray; 
iris bright yellow. Length, 184; wing, 145; tail, 72: culmen from base, 
17; tarsus, 33. 
Adult female.—Similar to the male. Length, 190; wing, 153; tail, 71; 
culmen from base, tip broken, 18; tarsus, 30. 
Downy young.—The natal down is pure light gray; this soon gives 
place to a soft gray plumge barred with brown, darker on head and upper 
parts. A nest with three downy young was found in Benguet, Luzon, 
on May 26. 
“A single male specimen of this remarkable little owl was obtained. It 
most nearly resembles Scops pennatus, but may be instantly recognized, 
by having the basal half of the tarsi entirely devoid of feathers, as well 
as by the length of the horn-like feathers on the head, which measure 
38 mm., whereas in S. pennatus the longest are only 23. The markings 
on the feathers of the head are coarse and form black bands, and the 
whole of the markings on the back and under parts are coarser and less 
neat. Length, 203; wing, 142; tail, 74; tarsus, 29; of which 15 is naked 
and covered with small octagonal scales.” ( Grant.) 
The subject of Grant’s remarks, quoted above, was a long-horned 
screech owl collected by Whitehead in “North Luzon.” The same col- 
lector secured specimens in Lepanto and I have seen a living example 
which was reported as having come from Nueva Ecija.
