to the general plumage ; frontlet usually more or less distinctly white, 
but this sometimes wholly absent; occipital feathers pure white beneath 
the surface ; outer surface of primaries plain black, without the slightest 
indication of spots or bars. Tail browish-gray, or grayish-brown, crossed 
by about six or seven narrow bands of black, of which the subterminal 
is much the broadest, the grayish bands becoming gradually narrower 
toward the base of the tail ; under surface of the tail appearing silvery 
white, with cross-bands of slate-color. Under surface of the primaries 
chiefly white anterior to their emargination, but this broken by irregular 
bars, or, as is sometimes the case, confused mottlings of grayish; rest 
of under surface of the wing uniform dark brown or black, the under 
primary-coverts sometimes spotted or barred with white. Bill black, 
bluish basally ; cere and feet yellow; iris brown. $ : Wing, 11. 20-11.70; 
tail, 7.00-7.30; culmen, .70-.75 ; tarsus, 2.05-2.25; middle toe, 1. 35-1. 40 
(4 specimens). $ : Wing, 11. 90-13. 10; tail, 7.50-8.00; culmen, -78— .85 ; 
tarsus, 2.50-2.65; middle toe, 1.50-1.60 (6 specimens). . 
Young : Very similar to the adult, but tail dull brown with more numer- 
ous, narrower, and much less distinct bars of dusky, usually 8-9 in num- 
ber. Contour feathers (both above and below) with much concealed 
white on the basal portion of the feathers, the lower parts sometimes 
slightly varied with white or ochraceous spots and streaks, the axillars 
and under wing-coverts wdth small round spots of the same, and the under 
tail-coverts spotted with ochraceous. 
Specimens of this form are exceedingly constant in their char- 
acters, the eleven which have come under my notice being so 
much alike that all variations are covered by the terms of the 
above diagnoses.’ 
A specimen from Mazatlan (12,117, U. S. Nat. Mus. ; Col. 
Abert) , appears to very exactly resemble in coloration the type 
of B. fuliginosus, as described and figured by Dr. Sclater. The 
dimensions also agree rather closely, as may be seen below : —

black and more uniform on the lower parts, which show no markings 
whatever, though the concealed bases of the feathers are white ; frontlet

beneath the surface, showing wherever the feathers are disarranged ; inter-
