. Key to North American birds. Containing a concise account of every species of living and fossil bird at present known from the continent north of the Mexican and United States boundary, inclusive of Greenland and lower California, with which are incorporated General ornithology: an outline of the structure and classification of birds; and Field ornithology, a manual of collecting, preparing, and preserving birds. Birds; Birds; 1887. 510 SYSTEM A TIC SYNOPSIS. — BAP TORES — STBIGES. 477. S. n. al'leni. (To J. A. Allen.) Florida Bakeed Owl. Like iS". nebulosa proper, but toes almost entirely naked. The fcatliering of the tarsus stops at the roots of the toes almost as abruptly as it does in Scops flammeola, in comparison with S. asio, tliough a slight strip of bristly feathers runs along the outside of the middle toe. The barring of the breast seems t(j be heavier, on an average. Florida ; a local race. 478. S. occidentals. (Lat. occidentalis, western.) Western Barred Owl. Toes feathered as in S. nebulosa. Decidedly smaller than that species, and otherwise readily distinguished. Ground-color of upper parts much the same, but the barring brolien up into spotting, for the most part; on the back and wing-ctiverts resulting in uTegular variegation, on the head making small round white spots. Wings, tail, and facial disk much as in S. nebulosa. Under parts quite different, the markings being in bars everywhere, with little difference in pattern between the beUy and the breast. The latter is closely and regularly barred fl-ith brown and white, as in S. nebulosa, and if the barring is at all different on the belly, it is fi'om separation of the wliite bars into pairs of spots, in any event very different in appearance from the firm length- wise stripes of S. nebulosa. The difference between the two species in this regard is comparable to that between the 1 'g- and short-eared owls. The hning of the wings is fully sp<jtted witli dusky on a tawny gr^ and. Tlie ge
