“The general color of the upper surface in this species is a dark umber- 
brown; but the base of the feathers of the creast is white and the margins 
of the other occipital feathers are of a light yellowish brown. Some of 
the scapulars and other alar feathers (especially the latter) are slightly 
tipped with the same; the tail, which is of a somewhat lighter brown than 
the back, is tipped with a very narrow edging of white, and is also crossed by 
seven blackish brown bars, the upper one, however, being somewhat in- 
distinct, and the two lower being separated by an interval which is twice 
the breadth of the spaces between the other bars. The throat has a broad 
blackish band running down the center, with two similar and nearly 
parallel bands proceeding from the corners of the mouth, the three bands 
all merging in a cluster of dark brown laceolate marks upon the upper 
portion of the breast, the intervals between these markings, and also the 
whole sternal and abdominal regions, being tinged with a yellowish 
rufous; the under tail-coverts are barred with brown and white, the 
former bars being much broader than the latter; and the thighs and tarsi 
are marked throughout their length with narrow, equidistant, transverse 
bars of the same color. Length, 635; crest, 63; wing, 375; tail, 292; 
tarsus, 89; middle toe with claw, 76.” (Sharpe.)
