244 DR. J. J. KAUP’S MONOGRAPH OF THE STRIGIDA. 
Dimens.—Head 90, bill from the gape 48, wings 315, tail 167 mm. long. 
Ods.—The figure given by Temminck much resembles B. nepalensis, and has very 
few resemblances to the male, which I have described. I am not quite sure that these 
two species are not subspecies of one and the same type. 
12. Buso nepaxensis, Hodgs. 
Diagn.—Size of Bubo maximus (600 mm.). Ear-horns, ear-margin, occiput, and under- 
parts with black arrow-like spots. Toes mostly thinly covered with feathers. 
Descr.—The largest species, with the longest ear-horns. Front dark brown, with 
rufous margins and cross-bands. Cheeks ashy-grey. Occiput-feathers white at the 
base, dark brown at the end, in the middle rufous-banded. Under parts rufous, with 
from two to four black cross-bands on each feather, which are arrow-like at the ex- 
tremity. Wings very much variegated, rufous-spotted, with irregular cross-bands and 
rusty yellowish-white, dark-brown-spotted margins. Tail on the under side whitish, 
with six black bands ; on the upper side brown, with five pointed rusty-yellow bands 
and broad white ends.

ash-grey, with fine lacerated drawing. 
Descr.—Size of Bubo coromandus. TEar-horns shorter, black-banded and pointed. 
Cheeks white, with blackish zigzag bands; near the furcula often darker. Along the 
shoulder-coverts and on the small feathers of the wing are white, dark-pointed spots : 
on the tarsi and under tail-coverts white spots. I have seen specimens with naked and 
with feathered toes. 
Hab. Africa. 
Subgenus e. Pseudoptyna. 
Diagn.—Ketupe with feathered tarsi, and feather-horns not distinct.

Descr.—Size of Bubo ketwpa. Upper parts dark brown, with rusty-yellow or rufous 
margins. The shoulder-coverts have white margins on the outer webs, which form a 
stripe. The wing-feathers have from four to five rufous spots, not reaching to the shaft. 
The arm- and hand-wings have whitish margins. The end of the tail has distinct
