Characters. Bill rather wider at the base and more distinctly ridged than in the genus 
Pipra, though otherwise very similar in shape. Feathers of the middle of throat much 
elongated. Wings short and rounded, the second, third, fourth, fifth and sometimes the sixth 
primaries being nearly of equal length. The outer primaries are of a very peculiar shape, 
especially in the males. They are much attenuated in the webs, and strongly curved inwards. 
The stems of the inner primaries and of the secondaries thickened and rather stiff, Tail nearly 
square. Metatarsus and toes much stronger and longer than in Pifra, and always of a yellowish 
flesh colour. , 
Sexes widely different in coloration, the males being black and white, yellow or orange, 
while the females are clad in olive green garments, the abdomen alone being sometimes dull 
yellow. In the female sex, the outer primaries are less attenuated and less curved, though 
always much narrower than the inner ones. The throat-feathers are likewise less elongated. 
Little is known about the habits and nidification of the species of this genus. Salmon 
(Proc. Zool. Soc. Lond. 1879, p. 517) tells us that C. manacus abditivus builds a slight shallow 
nest of grasses, which is suspended from the fork of a branch in low shrubs, and Euler (four, 
f. Ornith. 1867, p. 223) made the same observations on C. manacus gutturosus. The eggs are 
white, thickly blotched with brown or chocolate red, the blotches being more or less confluent 
in a zone round the larger end. Those of C. manacus abditivus and C. vitellina are figured by 
Stlater & Salvin (Proc. Zool. Soc. Lond. 1879, tab. 42). According to Euler (loc. cit.), in 
C. manacus gutturosus the clutch consists of two eggs only.
