DR. J. J. KAUP’S MONOGRAPH OF THE STRIGID#. 245 
cross-bands. The lower parts are whitish, with rufous tint and black shaft-spots. 
Tarsi grey ; bill yellow. The not very distinct ear-horns black. 
Dimens.—Head 90, bill 30, from the gape 43, Wings 320, tail 162, tarsus 61, middle 
toe 37 mm. long. 
Hab. Philippine Islands. 
In its dimensions this species comes very near to Bubo ketupa. The only specimen 
of this rare bird as yet known is in the rich Collection of the British Museum. 
Genus IV. Srrix, Linn. 
a. Phodilus. b. Strix. c. Scelostrix. d. Dactylostrix. e. Megastriv. 
Diagn.—The nail of the middle toe on the interior margin clearly pectinated. 
Descr.—The bill projected, near the cere straight, and of light yellowish colour. 
The ear-orifice square, placed between two skin-flaps, and bounded on the upper and 
lower margin by a membrane (PI. LVII. fig. 8, a a). The hind ear-lap is as broad 
as long; the anterior ear-lap or operculum is broadest in the middle of its height. 
The whole ear-slit begins over the eyes and reaches nearly to the gape, as in Otus. 
The eyes separated by a thick bony wall. No asymmetry. The tarsi slender, and more 
thinly covered with feathers, more at the bottom than next to the tibie. The outer 
toes stronger, and as long as the middle toes. The plumage very much developed, with 
much down, and finely and elegantly coloured. The eyes always brown. 
These birds are spread over all parts of the world. The smaller ones live on mice 
and little birds ; the larger species attack mammalia and birds. 
Subgenus a. Phodilus, Is. Geoftr. 
Diagn.—Wing short. First wing-feather as long as the tenth. Toes naked, scaled, 
and without bristle-feathers.

Phodilus badius, Is. Geoffr. Ann. de Se. Nat. xxi. p. 201. 
Descr.—Smaller than Strix flammea, but very near to it in colour. Front, veil, and 
lower parts white, tinged with rufous ash-grey. On the lower part are two round 
black spots on each feather. The small feathers on the upper parts rusty-yellow, with 
round black spots, which on the wings are margined with white. The margins of the 
wings white, black-spotted. On the inner side of the wing are seven or eight bands. 
The tarsi pretty thickly feathered, and the nails in comparison very long and strong. 
Dimens.—Head 64, bill from the gape 33, wing 213, tail 73 mm. long.
