Adult males have the crest-feathers aud the thighs uniform black, while they 

 are spotted with white in immature specimens. 



The series of the females substantially corroborates what I said about the 

 distinctness of C. sclateri and C. pinima Pelz.f The ujjper wing-coverts, quills, 

 rectrices, and the whole back are crossed by regular bars of white or pale buff, the 

 under-surface of the remiges is banded with white on both webs, aud the middle 

 of the breast, the abdomen and under tail-coverts are uniform deep ochraceons buff. 



In eleven examples the crest is coloured as described by me I.e., viz. basal 

 fourth and apical poition of the feathers black, separated by a long band of white. 

 Two others, Nos. 2383 and 2415, however, have two white spots on each of the 

 crest-feathers, a subapical one, and another near the base. In this respect they 

 agree with the description and plate of Crax fasciolata Spix.J Both specimens are 

 immature, and differ also from the adult ones by having the throat spotted with 

 white. No. 2415 shows yet another character of immaturity in the light bands 

 on the median and greater upper wing-coverts being much broader and deeper 

 lu colour, buff (instead of creamy-white). Though it now seems possible that 

 C. Jasciolata might have been based upon an immature female of C sclateri, I shall
