Adult male. A full black crest of long feathers covering the top 

 of the head ; nape (and feathered parts of the head), throat, neck, 

 and chest chestnut, shading into brownish chestnut on the mantle, 

 •which, like the rest of the upper parts, is finely vermiculated all 

 over with black ; quills brownish black, the primaries slightly and 

 the secondaries largely vermiculated with rufous buff on the outer 

 web ; breast and rest of underparts cinnamon, slightly mottled on 

 the sides with dusky ; tail black, tipped with whitish buff, except 



* This specimen has been described under the above name as a distinct 

 species on account of the swollen cere and wattles at the base of the lower 

 mandible being pale green instead of blue, but this difference is no doubt 

 merely due to individual variation.
