Genus SCOPS, Savigny.

Gen. Char. Size small, the head provided with ear-tufts. Bill light-colored; iris yellow. Three to four outer quills with inner webs sinuated. Wings long (more than twice the length of the tail, which is short and slightly rounded); second to fifth quills longest. Toes naked, or only scantily feathered. Ear-conch small and simple. Plumage exceedingly variegated, the colors different shades of brown, with rufous, black, and white, in fine mottlings and pencillings; feathers above and below usually with blackish shaft-streaks, those beneath usually with five transverse bars; primaries spotted with whitish, and outer webs of the lower row of scapulars the same edged terminally with black. Tail obscurely banded.

Scops asio.

The species of this genus are cosmopolitan, the greater number, however, being found in tropical regions. All the American species differ from S. zorca of Europe in having the fourth and fifth quills longest, instead of the second, and in having three to four, instead of only two, of the outer quills with the inner web sinuated, as well as in having the quills shorter, broader, and more bowed, and their under surface more concave. They may, perhaps, be distinguished as a separate subgenus (Megascops, Kaup). Of the American species all but S. asio (including its several races) have the toes perfectly naked to their very bases.

Outer webs of primaries with nearly equal bands of whitish and dusky.
