1lab .—Brazil to Guatemala* 
Wing, 5.20-6.50 ; tail, 3.90-5.50 • culmen, 0.45-0.55 ; tarsus, 1.40-1.90; 
middle toe, 1.00-1.35. Third or fourth quill longest; first shortest; 
inner web of outer four distinctly emarginated. Lower parts, except 
throat (and sometimes the anal region), with distinct transverse bars 
of rufous, brown, or plumbeous, on an ochraceous or white ground. 
Adult. —Above dusky, the pileum nearly black, and the back with a 
decided plumbeous cast. Tail with four to five bands of blackish and 
plumbeous or brownish-slate (the two colors in nearly equal propor¬ 
tion,) and sometimes with a narrow terminal margin of white. Ear-cov¬ 
erts and sides of nape plumbeous, the former usually somewhat broken by 
a faint, whitish, indistinct barring. Lower parts white, the entire sur¬ 
face covered with numerous, regular, transverse bars of light slate or 
plumbeous, these bars usually wider on the sides than along the median 
portion, widest apart on the crissum, and most numerous and dense on 
the tibire ; axillars and lining of the wing similarly barred. Inner webs 
of primaries with transverse spots of dusky slate from base to end. 
Gular region white, without bars. 
Young.—Brown phase : —Above, sepia-brown, the pileum nearly black; 
the feathers with or without rusty borders. Tail lighter, and crossed by 
six to seven bands of dusky black. Lower parts white or pale ochraceous, 
barred as in the adult, but with rusty-brown or umber, instead of slate 
or plumbeous. Rufous phase : —Above, bright rusty-rufous, brightest on 
the tail, more dusky on the pileum. Tail with six to seven narrow bands 
of black, these sometimes not reaching from the shaft to the edge of the 
feathers. Lower parts pale ochraceous or rufescent white (the tibiae 
quite rusty), barred as in other stages, but with deep rufous or rusty- 
brown. 
That the rufous plumage of this species is not a progressive stage, 
but a mere individual phase, is proven by the examination of individ¬ 
uals in the transition-state. One of this character in Mr. Salvin’s col¬ 
lection, from Veragua, originally an extreme example of the rufescent 
phase, was moulting directly into the adult plumage described above, as 
numerous new feathers in all parts of its plumage plainly show. 
Another, in the same collection, from Bahia, is an adult in somewhat 
worn plumage, still retaining a few bright-rufous feathers among the 
axillars. On the other hand, specimens which are in the sepia-brown 
plumage, usually regarded as an intermediate stage between the rufous
