Subgenus b. Otus, Kp. 



Diagn. — With small curved bill and long wings. The first wing-feather not so long 

 as the fourth. The first wing-feather distinctly emarginated near the end, the second not 

 so distinctly. Toes mostly covered with feathers to the scales next the nails. The 

 dentellated margin of the first wing-feather very much developed. This subgenus is 

 connected with the fourth subgenus, Brachyotus, Gould. 



It appears that this subgenus contains species which are more night-birds than the 

 other subgenera. 0. vulgaris, 0. americanus, and 0. zonurus are formed on one and the 

 same type. Otus stygius is a second type species.

 folds of the operculum covered with rusty-yellow feathers, having blackish shaft-points, 

 and some not very distinct blackish spots. The margin of the operculum with two 

 series of feathers placed in pairs, which are white, tinged with rusty-yellow ; they have a 

 broad black margin, and blackish roots with white shafts in the centre. The first series 

 of feathers on the hinder ear-margin is stiff and black, except those of the superior 

 and interior margins, which are softer and have white ends. The front and cap-feathers
