Colour. — The upper surface of the head, dull green, faintly freckled with 
black ; the sides of the head and the chin straw yellow ; eye-brows yellowish 
white ; space between eye and bill black ; the neck, the breast, and a 
portion of each shoulder, intermediate between oil green and sulphur yellow ; 
the bases of all the feathers pearl-grey ; immediately behind the yellow of 
chin, the throat and sides of the neck are crossed by a deep brownish black 
crescent. The interscapulars and scapulars clouded with pale reddish brown, 
pearl-grey, and bluish black, or brownish black, the latter generally prevailing 
towards the quills. Back and upper tail coverts pearly grey, strongly tinged 
with brown, and when the feathers are separated, each is found of a yellowish 
brown tint at the base, and with a strong satin lustre. The secondary wing 
coverts intermediate between Dutch and reddish orange, with the base, and a 
considerable portion of the inner vane of each pearly-grey ; primary wing 
coverts, and all the quill feathers, umber-brown ; the secondaries narrowly 
tipt with rusty white; the tail feathers blackish brown, the outer vanes edged 
with pearl-grey, and all, except the two middle ones, broadly tipt with the 
same colour as the secondary quill coverts. Belly and under tail coverts, be- 
tween chesnut and reddish brown. Bill and claws a dark horn-colour ; eyes 
dark brown ; toes greenish brown. 
Form, &c.— Typical ; wings, when folded, nearly reach the tip of the tail ; 
the first quill feather rather longer than the second ; the longest of the 
tertiaries intermediate between the sixth and seventh quill feathers ; tail, 
wedge-shaped, the two middle feathers rather the longest, and acuminated at 
their extremities; the outer and inner toes of equal length.
