Adult male. Head, neck, back, rump, wings, and thighs brownish 

 black glossed with dark green ; middle of throat, breast, and belly dull 

 chocolate-brown, rather paler on the abdomen and slightly glossy ; 

 under tail-coverts brownish grey ; tfil glossed with green, last two- 

 fifths black, rest brownish grey : bill black. Total length 32 

 inches, wing 14-5, tail 11-6, tarsus 2. 



Young male differs from the adult in having the crest much less 

 developed ; the greater and median wing-coverts, secondary quills, 

 and long scapulars margined with pale bufE on their outer webs ; 

 and the breast and belly pale brown : bill dull red at tip, pea-green 

 at base {J. Whitehead). 



As age increases the anterior parts of the bill become whitish 

 yellow, and the base of the maxilla, basal half of the lower mandible, 

 and upper part of the casque black. In this stage the plumage is 

 quite similar to that of the adult. Gradually the black increases in 

 area, till only a white line is visible along the base of the casque, 

 and this also disappears in time. 



Adult female does not differ except in size from the adult male. 

 Total length 29 inches, wing 13-3, tail 11, tarsus 1-9, 



Toung female resembles young male.
