Adult Male. 



Bill of moderate length, extremely thick, conical, pointed; upper mandible 

 with the dorsal line very slightly convex, the sides rounded, the edges sharp, 

 overlapping, with a slight sinus close to the acute tip; lower mandible with 

 the angle very short and broad, the dorsal line straight, or very slightly con- 

 cave, the back very broad, the sides rounded, the edges inflected, the tip 

 acute. Nasal sinus extremely short and broad; nostrils round, basal, con- 

 cealed by short reflected bristly feathers. 



Head large, roundish-ovate; neck short; body moderately full. Feet short, 

 of moderate strength; tarsus short, compressed, with seven anterior scutella, 

 and two plates behind forming a sharp edge; hind toe large, outer toe some-

Plumage full, soft, blended, the feathers oblong. Wings rather long, 

 broad, abruptly pointed; the outer three primaries almost equal, the first 

 longest; outer secondaries emarginate. Tail of moderate length, rather 

 narrow, emarginate, of twelve rather narrow feathers. 



Bill yellow; iris hazel; feet flesh-colour, claws brown. The upper part of 

 the head and the occiput are brownish-black, bounded anteriorly by a broad-

 scapulars, the rump, the axillars and inner lower wing-coverts, the abdomen 

 and lower tail-coverts, it becomes pure yellow. The smaller wing-coverts,
