234 DR. J. J. KAUP’S MONOGRAPH OF THE STRIGIDA. 
Descr.—A handsome and very distinct species. The bill yellow, the lower jaw black. 
The face black, with large whitish spots on the roots of some bristle-feathers and feathers 
of the anterior ear-coverts. The front and hind ear-margins covered with black feathers 
spotted with white andrufous. Under the dirty-white chin are long rusty-yellow narrow 
feathers with a black stripe along the shaft, and on the sides next them pure white feathers 
with black ends. Feather-horns black, with a rusty-yellowish spot at the base of the 
inner web. Head and neck rusty-yellow, black predominating at the top of each feather. 
Shoulder-coverts and wings blackish-brown, some feathers only with whitish and rusty- 
red marbled drawing on the exterior web. The inner side of the wings has the shafts 
of the feathers white, with a large triangular white spot next to the shaft, a second, 
more round, in the middle, and a third, more indistinct, near the emargination. The 
inner coverts of the wings are rusty-yellow spotted with black. Under parts rusty-yellow 
with broad black shaft-stripes, and white spots on the webs pointed with black at the 
end. The tail black, at the base white, with seven narrow white bands and broad white 
end-margins. The upper part only with four rusty-yellow, blackish-pointed bands no 
reaching to the end of the feather-margins. Tarsi rusty-yellow, blackish-spotted, near 
the toes black. The toes are in a great measure naked ; but I think this is an accident, 
and not found in all the specimens. The figure of d’Orbigny gives the yellow toes 
completely naked. 
Dimens.—Head 70-71, bill from the gape 32, wing 325, tail 178, tarsus 46, middle 
toe without nail 35 mm. long. 
Hab. Cuba. 
6. Orus zonurus, G. R. Gray. 
Diagn.—The under part of the wing and tail with twelve cross-bands. 
Descr.—The plumage is also darker: black predominates on the upper and lower 
parts. 
Hab. ——? 
Dimens.—Otus vulgaris: head 58, bill from the gape 30, wing 275-279, tail 150,

three species are very nearly the same.
