Coloration. Similar to G. radiatum, except in having the back, rump, scapulars, and whole upper surface of the wings overlaid with chestnut, so that the narrow cross-barring is seen more or less distinctly through it, and in having longitudinal olive streaks on the abdomen, and traces of them on the lower tail-coverts and legs instead of cross-bars. The rufous bars on the wing-feathers are narrower and more numerous, and they extend across all the feathers, whilst the basal portions of the inner webs are buff instead of rufous. The white spots on the wing-coverts and scapulars are often wanting, but occasionally well developed.

Bill greenish horn-colour; cere dusky greenish; iris yellow; feet olivaceous, soles yellowish; claws brown (Legge).

Length about 7.5; tail 2.6 ; wing 5.2; tarsus .85 ; bill from gape .75.

Distribution. Peculiar to Ceylon, where this Owl is chiefly found in the hills.

Habits, &c. These differ very little, if at all, from those of the last two species. The food consists chiefly of insects and lizards, occasionally of small mammals and birds. The cry is a repeated guttural sound often heard long after sunrise and before sunset. The eggs are laid in a hole in the trunk or branch of a tree from March to May; they are (so far as is known) two in number, white, oval, and about 1.37 by 1.11.
