Scops Rrpeway, Loc. cit. (Cape St. Lucas; crit.). 
Megascops asio trichopsis (not Scops trichopsis WAGLER) Bryant, Proc. Calif. Acad. 
Sci., 2d ser., II. 1889, 284 (Cape Region; ? Victoria Mts., etc.). 
Specific Characters : — Most nearly like J/. vinaceus Brewster,! but smaller, the 
general coloring paler and less reddish, the crown and outer surfaces of the wings 
lighter, the primaries with broad, well-defined light bars on both webs, the abdomen 
and flanks decidedly whiter, the under tail coverts nearly pure white and practically 
without mesial streaks, the feathering of the legs shorter and sparser. 
& ad. (No. 47,301, collection of William Brewster, Santa Anita, Lower Califor- 
nia, June 3, 1896; Loye Miller).2_ Upper parts drab, tinged with pinkish rusty on 
the back, inclining to ashy on the pileum and outer surfaces of the wings, to ashy 
white on the lores and sides of the crown, all the feathers except the primaries 
faintly vermiculated with reddish brown, those of the forehead, “ear tufts,” back, 
rump, scapulars, and wing coverts with narrow shaft streaks of clove brown; pri- 
maries, secondaries, and tail-feathers barred with wood-brown, the bars on the tail 
narrow and distinct, excepting near the tips of the feathers, where they are broken 
and confused, those of the wings broad and distinct on both webs of all the pri- 
maries, but only faintly defined on the inner secondaries ; outer scapulars, greater 
wing coverts, and outer primaries, with their exposed outer edges, hoary white; 
cheeks, throat, and breast pale ashy with the faintest possible suffusion of pinkish 
or rusty; abdomen, flanks, and crissum soiled white or ashy white; most of the 
feathers of the under parts with exceedingly fine, wavy, transverse lines of reddish 
brown, those of the throat, breast, and sides (but not of the under tail coverts nor 
of the center of the abdomen) with narrow, sharply-defined, mesial streaks of dark 
clove brown; tibiae tinged with fulvous and barred with reddish brown; under 
wing coverts pale fulvous heavily marked with dark brown; tarsi rusty white with 
a few reddish brown spots; toes naked nearly to their bases. Wing, 5.35; tail, 
2.72; tarsus, 1.32; middle toe, .65; bill, length from nostril, .82; depth at nostril, 
40; longest feathers of ‘‘ ear tufts,” .90. 
Two young birds (No. 16,932 @ and No. 16,933 Q, U.S. National 
Museum Collection, Cape St. Lucas; J. Xantus), fully grown but still in 
juvenal plumage, differ from the adult specimen just described in being much 
darker, browner, and more uniformly colored, in lacking all trace of mesial or 
shaft streaks on the feathers of the body, and in having the broad, light bars 
on the wing quills more rusty and nearly as pronounced and well defined on 
both webs of all the secondaries as on those of the primaries. The upper parts 
are faded reddish brown (not far from russet) with obscure, transverse lines of 
whitish on the pileum, back, and wing coverts; the cheeks, throat, and under 
parts generally are everywhere crossed by bands of reddish brown, which are 
much narrower than the brownish-white interspaces; the feathering of the 
legs is even scantier than in the mature bird. 
On comparing both old and young with specimens in corresponding plumages 
of bendirei, trichopsis, and cineraceus, the only representatives of the M. asio
