much rounded, the longest primaries but little longer than sec- 
ondaries; sixth and seventh or fifth, sixth, and seventh, primaries 
longest, the tenth (outermost) about three-fifths as long as the 
longest. Tail about as long as wing, graduated for about one-third 
its length, the rectrices (12) rather broad and rounded terminally. 
Tarsus more than one-third as long as wing (about as long as bill 
from rictus to tip of maxilla), rather slender, distinctly scutellate, 
the plantar scutella in two parallel, contiguous rows; middle toe, 
with claw, much shorter than tarsus; outer toe (without claw) 
reaching to or beyond middle of subterminal phalanx of middle toe, 
the inner decidedly shorter, reaching (without claw) about to sub- 
terminal articulation of middle toe; hallux about as long as inner 
toe but much stouter; middle toe united to outer toe for whole of 
its basal phalanx, to inner toe for about half as much; claws mod- 
erate, strongly curved, that of hallux decidedly shorter than the 
digit. Plumage full, blended, moderately lax, that of the rump 
much developed; pileum with a full decumbent crest of broad, 
rounded feathers. 
Coloration. Adult male black, the upper parts (except pileum) 
narrowly, the under parts more broadly, barred with white; adult

Similar to C. 1. lineatus* but averaging decidedly larger; adult 
male with black bars on under parts averaging decidedly broader 
(especially on throat), the adult female and young with under parts 
much more strongly buffy and (usually, at least,) more heavily barred. 
Adult male.—Pileum black, the forehead (sometimes crown and 
occiput also) narrowly barred with white; rest of upper parts black, 
narrowly and rather distantly barred with white, the outer webs of 
primaries and distal secondaries with small spots of white in trans- 
verse series; sides of head and neck and entire under parts sharply 
barred with black and white, the bars of the two colors about equal 
in width; maxilla black, mandible pale grayish or dull yellowish
