PENTHOCERYX. ote 
indicated by three white feathers; a few rufous partial bars on the wings 
and tail; chin and throat blackish brown, the feathers of the latter with 
very narrow whitish terminal edges; remainder of the under surface of 
the body blackish brown and white in broad bars of even width. Length, 
127; wing, 94. 
“Young nearly full-grown.—Differs from C. canorus at this stage in 
being much blacker, in generally having no white feathers on the nape, 
and in the greater breadth of the black bars on the throat and breast, 
which are seldom narrower than the white space between them. 
“Rufous phase-——Compared with the rufous phase of C. canorus, it is 
darker, the dark bars being broader and blacker; lower back and upper 
tail-coverts barred with black like the crown; tail with very distinct black 
bars forming angles at the shafts of the feathers; under surface of the 
body similarly colored, but much more broadly barred with black than 
in C. canorus. Length, 282; culmen, 22; wing, 178; tail, 155; tarsus, 
18.” (Shelley.) 
Genus PENTHOCERYX Cabanis, 1862. 
“This genus resembles Cacomantis in structure and size, the only 
structural distinctions being that the bill is much stouter and broader 
up to the tip, which is blunt when seen from above, and that the tail- 
‘feathers become narrower behind instead of remaining of the same 
breadth. The wing is shaped as in Cacomantis, the primaries only 
exceeding the secondaries by one-third the length.” (Blanford.)
