Birds; Birds. 510 SYSTEMATIC SYNOPSIS. — — STBIGES. 477. S. n. al'leni. (To J. A. AUen.) Florida Baeeed Owl. Like S. nehulosa proper, but toes almost entirely naked. The feathering of the tarsus stops at the roots of the toes almost as abruptly as it does in Scops flammeola, in comparison with S. asio, though a slight strip of bristly feathers runs along the outside of the middle toe. The barring of the breast seems to be heavier, on an average. Florida; a local race. 478. S. occidentalis. (Lat. occidentalis, western.) Westben Barebd Owl. Toes feathered as in S. nehulosa. Decidedly smaller than that species, and otherwise readily distinguished. Ground-color of upper parts much the same, but the barring broken up into spotting, for the most part; on the back and wing-coverts resulting in iiTegular variegation, on the head making small round white spots. Wings, tail, and facial disk much as in 8. nehulosa. Under parts quite different, the markings being in bars everywhere, with little difference in pattern between the belly and the breast. The latter is closely and regularly barred with brown and white, as in S. nehulosa, and if the barring is at all different on the belly, it is irom separation of the white bars into pairs of spots, in any event very different in appearance from the firm length- wise stripes of S. nehulosa. The difference between the two species in this regard is comparable to that between the Ic g- and short-eared owls. The lining of the wings is fully spotted with dusky on a tawny gn and.
