DR. J. J. KAUP'S MONOGRAPH OF THE STRIGID^. 243 



Subgenus d. Urrua, Hodgs. 



Diagn. — Bill very strong and projected. The first wing-feather to the sixth clearly 

 emarginated on the inner web, nearer to the base of the wing-feathers. Tarsi feathered ; 

 toes thinly feathered. Nails of the usual form. 



The birds of this division show a greater affinity to the second subgenus, Bubo, than 

 to the first, third, or fifth subgenera. Like Ketupa, they must have a rushing flight. 

 From their very strong bill, powerful tarsi, and longer toes and nails, they would appear 

 to be more rapacious than the second subgenus, Bubo. 



Possibly they are not sleepy by daylight, as is the case with the true Bubo, which 

 represents the genus Otus in its genus.

Descr. — A male specimen, of smaller dimensions, in the British Museum has the 

 upper parts dark brown, with a great number of narrow rusty-yellowish bands, four 

 to six on each feather; the under parts whitish, with a great number of black 

 bands, four to six on each feather. A stripe over the eye to the longest feathers of 

 the ear-horns nearly black. The base of the wings on the inner side whitish. The 

 wings near the emarginations brownish, with two whitish irregular spots not reaching 

 the shafts. The tail brown, with three to four narrow, very indistinct cross-bands, 

 and broader greyish-white-spotted terminations. The under side of the tail at the base 

 and the inner webs more whitish, and with three to four very irregular bands. Tarsi 

 black, cross-banded. The bill and toes, which are completely naked, yellow.
