of the Genus Hemicercus. 249 



grey, the latter having a slight olive tinge. Total length 

 5'0 inches, culmen 0*75, wing 3"3, tail 1*0, tarsus 0*6. 



Young female. Having the forehead and crown rufous 

 buff, the occipital crest slightly more rufous, the feathers of 

 the latter with dusky tips. 



I subjoin a short description of the various stages of plu- 

 mage through which this species passes, from the nestling to 

 the adult, q,s far as the series of specimens examined will 

 permit ; and without asserting that the links in the chain are 

 complete, I think most of the changes of plumage are enume- 

 rated in these notes. 



15/ stage. — Male, nestling. Forehead, crown, and crest 

 rufous buff, the latter with only a trace of flame-red, and 

 varied with dusky, as well as having dusky tips to the feathers, 

 those of the forehead and crown having their tips alone 

 dusky. 



2ind stage. — Forehead and crown rufous buff, the feathers 

 having dusky tips, a few red feathers appearing on the crown ; 

 the crest a mixture of flame-red and rufous buff, the feathers 

 having dusky tips. 



^rd stage. — Forehead and crown as in the latter stage, 

 with numerous red feathers appearing ; crest olive-grey 

 mixed with reddish buff. 



Mh stage. — Forehead and crown vermilion-red ; crest olive- 

 grey, barred with dull baff. 



^th stage. — Forehead and crown vermilion-red, the hinder 

 feathers of the crown elongated ; occipital crest olive-grey. 

 This is the fully adult male. 



\st stage ? — Female, young. Forehead and crown pale 

 rufous buff, the crest more rufous, the feathers of the latter 

 having dusky tips. This is the first stage of plumage in 

 which I have seen the female ; but there is very probably an 

 earher one, in which the feathers of the forehead and crown 

 will have dusky tips. 



2nd stage. — Forehead, crown, and crest olive-grey, some 

 of the feathers of the crest being barred with huffy whitish. 



^rd stage. — Forehead, crown, and crest entirely olive-grey. 

 This is the fully adult female.
