52 NORTH AMERICAN BIRDS. 



America, and the S. atrkapilla, Tenim., of Tropical America generally. The 

 colors, as may be expected, are also darker and richer. 



In the collection of the Smithsonian Institution there are both red and 

 gray birds from Florida ; a red one (Xo. 5,857, Indian lUver ; Dr. A. W. 

 Wall) measures, wing, 5.50 ; tail, 2.70 ; culmen, .55 ; tarsus, 1.05 ; middle 

 toe, .65 ; ear-tufts, .70. The colors are nuiuli darker than those of t}^iical 

 asio. The rufous of the neck, all around, shows obsolete darker transverse 

 bars ; tlie black border to the white scapular spots is restricted to the tip, as 

 in the gray plumage ; the inner webs of the ear-tufts are scarcely paler tlian 

 the outer; the neck and face are deeper rufous, while the rufous of the 

 lower parts is more general, and more in transverse rays ; tibia3 and tarsi 

 plain rufous ; the middle of the abdomen and the anal region only are pure 

 white.

Char. Adult (9,147, Camp 118, New Mexico, February 10, 18.54 ; Kennerly and 

 Mollhausen). Above cinereous, the ashy appearance being caused hy a minute trans- 

 verse mottling of blackish and pale ashy, on a deeper ash ground ; each feather with a 

 distinct medial stripe of black, these broadest on the forehead ; outer webs of only a few 

 scapulars white, these not bordered with black ; outer webs of two or three lower middle 

 and secondary coverts white. Secondaries with about seven transverse, mottled pale 

 bands ; primaries witli about eight transverse series of white spots ; tail with about eight 

 narrow pale bands. 



Ear-coverts, cheeks, throat, neck, and jugulum finely and uniformly bari-ed transversely 

 with dusky and grayish-white ; the facial circle interrupted across the throat, where in its 

 place is a series of longitudinal black dashes. 



Lower parts grayish-white, with numerous, very narrow transverse bars of dusky, 

 rather more distant from each other than those of the neck, etc. ; each feather with a 

 medial narrow stripe of black, those on the breast forming conspicuous spots ; tibiae and 

 tarsi dull soiled white, with numerous spots of dark brown ; lower tail-coverts immacu- 

 late. Wing-formula, 3 = 4-2, 5, 6, 7, 8-1-9. Wing, 6.50; tail, 3.30; culmen, .55; 

 tarsus, 1.15; middle toe, .70; ear-tufts, .85. 



(A specimen from California (Stockton, E. S. Holden), kindly sent by Mr. Lawrence for 

 examination, differs from the preceding in rather more brown ground-color above ; the 

 black shaft-streaks more obscure. In other respects as regards plumage it is the same, 

 and is typical maccalli. The size is less, it measuring, wing, 6.20; tail, 3.10.) 



Young (first full, but incomplete plumage ; 10,932, Cape St. Lucas, Lower California). 

 Secondaries, primaries, and tail as in the gray adult. Rest of the plumage transversely 

 barred with grayish-white and dusky, the latter predominating on the upper parts; eye- 

 brows and lores white j rings finely transversely mottled with white, this forming spots
