1163. Syrnium butleri.
Asio butleri, Hume, S. F. vii, p. 316; id. Cat. no. 67 bis. Syrnium butleri, Tristram, S. F. viii, p. 417.
Coloration. Facial disk white, tinged with tawny behind, some of the loral feathers black-tipped; ruff greyish brown, the feathers tipped with cream-colour or buff; upper plumage brown, banded irregularly, clouded, and intermixed with dull brownish buff, a few large white spots on the secondary, median, and greater coverts; quills and tail-feathers banded brown and brownish buff above, brown and whity brown beneath, tips of the quills mottled greyish brown; tips of tail-feathers white, the buff bars on the median tail-feathers replaced by irregularly-shaped spots; lower parts creamy white, the feathers edged with rufous brown, and with narrow brown shaft-stripes on the breast and upper abdomen; wing-lining white, a brown patch at the base of the primaries.
Length 14, or rather less; tail 5.75; wing 10; tarsus 2; bill from gape 1.2.
The tarsi, feet, and claws are very small. In the wing the 3rd quill is longest and the 4th very little shorter.
Distribution. Only two specimens are known—one, the type in the Hume collection, was obtained, there is every reason to believe, at Omara on the Mekran coast; the other was procured by Canon Tristram from Mt. Sinai. This Owl is somewhat intermediate between Syrnium and Asio, but appears more allied to the former, as it has a rounded wing and no aigrettes.
