indicated by three wliite feathers ; a few rufous partial bars on the wings 

 and tail; chin and throat blackish brown, the feathers of the latter with 

 very narrow whitisli 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.)
