Adult Female. — From forehead to nape dull rufous buff, the 

 feathers broadly edged black, especially in the centre, where the 

 black forms an indistinct coronal streak ; a full crest of bristly dark 

 grey feathers ; nape bright rufous chestnut with faint dark vermi- 

 culations at the bases of the feathers ; on the mantle the chestnut 

 becomes less bright and the vermiculations more numerous ; the 

 upper back scapulars and wing coverts about equally black and 

 chestnut, the latter colour paling posteriorly ; lower back, rump and 

 upper tail coverts the same but with definite bars of black mottled 

 with buff ; rectrices purple chestnut thickly mottled with black. 

 Primaries chestnut, lightly speckled with black on both webs, but 

 brighter on the outer than on the inner webs ; secondaries boldly 

 mottled with black and buff", tinged with chestnut on those next the 

 primaries. 



Below, chestnut, brightest and almost immaculate on the foreneck, 

 and dullest and inclined to buff on flanks and abdomen, vermiculated 

 with narrow black bars increasing in extent from breast to vent ; 

 under tail coverts dull brown, very finely stippled with dull rufous. 

 The vent is usually like the under tail coverts and the feathers 

 immediately surrounding it are often the same. 



Golo'iirs of the soft parts. — Iris dark brown ; legs and feet pale 

 vermilion or litharge red ; bill and claws horny white, dull white, or 



tinged with grey ; cere dull to dark brown ; skin of face and neck 

 dull grey or plumbeous blue to dark blue.

"Weight, 3-25 to 3-75 lbs." (Hume.) 

 Young Male in first plumage. — Like the adult female, but without 



crest developed as in that sex and with a longer tail. 



Chich in first plumage. — Like the female but with a bristly crest 



undeveloped and dark chestnut brown instead of black. The general 



tint is more ruddy, and the under plumage more boldly marked, the 



vermiculations running into definite bars. Even at this stage the 



inner secondaries exceed the primaries in length.
