induced to suppose it another species. The specimens in possession of Mr. 
Leadbeater of London, and from which Prince Bonaparte drew up his

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 somewhat longer than inner ; claws rather large, moderately arched, 
much compressed, acute. 
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- 
ish band of bright yellow across the forehead, and laterally by a streak of 
the same, passing over the eye ; the stiff feathers over the nostrils black, as 
is the loral space. The cheeks, hind neck, and throat, are dark yellowish- 
olive, and that colour gradually brightens until, on the outer edges of the 
scapulars, the rump, the axillars and inner lower wing-coverts, the abdomen 
and lower tail-coverts, it becomes pure yellow. The smaller wing'-coverts, 
alula, primary coverts, three outer secondaries, outer web of the next, and
