Colour. — The upper surface of the head and the lores deep umber-brown 
freckled with short and fine longitudinal dull white lines arising from each 
feather being narrowly edged and tipped with that colour ; sides of head and 
neck dull broccoli-brown, finely streaked with dirty white ; interscapulars, 
scapulars, back, and upper tail coverts intermediate between umber-brown 
and brownish red, each feather broadly margined with dirty white ; breast, 
belly, and under tail coverts mottled brown and dirty white. The brown is 
nearly of the same tint as that of the back, and is the predominating colour 
of each feather, the white existing only at the edges and in the form of an 
angular and incomplete bar about midway between the base and apex of 
each. Shoulder feathers and secondary quill coverts greyish brown, a part of 
the former narrowly edged with pale broccoli-brown, the other part with dull 
white ; the secondary quill coverts are tipped with velvet black, behind which 
each has a narrow bar of white. Primary quill coverts reddish brown, faintly 
edged exteriorly and tipped with greyish white. Primary quill feathers light 
brownish red, tinted with grey, the outer vanes darkest and narrowly edged 
with yellowish white ; shafts deep brownish red. Secondary quill feathers 
brownish red, broadly tipped with white, and behind the white each has a 
broad bar of velvet black, the outer vanes from near the quills to the last men- 
tioned bar are a brilliant shining duck green. The innermost of the secondary 
and the outermost of the tertiary quill feathers have the outer vanes velvet- 
black, so that three sides of the wing-speculum are bounded with that colour; 
the rest of the tertiaries are of the same colour as the back and are narrowly 
edged with dirty white. Tail intermediate between umber-brown and brownish
