Colour. — The upper surface of the head intermediate between hair-brown 
and oil-green ; the interscapulars, the back, and the rump oil-green ; the 
upper tail coverts oil-green, with a faint tinge of pale orange coloured brown. 
The shoulder coverts, and the primary and secondary quill coverts pale 
reddish brown, edged and tipped with king’s-yellow ; the primary, the 
secondary, the tertiary quill feathers and the scapularies pale reddish brown, 
the primaries toward their base and the secondaries throughout edged 
externally with oil-green, the tertiaries and scapularies edged and tipped 
with king’s-yellow. Sides of head oil-green, tinted with brown ; eyebrows, 
chin, throat, breast, belly, vent, under tail coverts, and libice king’s-yellow. 
Tail feathers light brownish red, broadly edged towards their base with 
king’s-yellow, and their points and the edges immediately in front of the 
former, particularly the outer ones, of a tint intermediate between king’s- 
yellow and straw-yellow. Upper mandible brownish red, lower light orange 
coloured brown. Tarsi, toes, and claws pale brownish red. 
Form, &c. — Head flattened and rather broad, body rather bulky considering 
the size of the bird ; wings rather short, rounded, and when folded reach a

Tail long, apparently square at the point when the feathers are fully 
developed, each feather at apex slightly rounded ; the interscapulars and the 
feathers of the under parts slightly decomposed. Bill much flattened, at the 
base broad and triangular (vide Fig. a) ; the culmen is distinct between the 
nostrils, which are situated close to the frontal feathers ; apex of bill slightly 
pointed, behind point moderately narrow and considerably arched ; bristles 
at corners of mouth short and moderately rigid. Tarsi rather short and
