and neck, each feather in the centre having a more 
lengthened mark of white. Tliis colour and the 
line on the crown is separated by a broad list of 
white arising anterior to the eye, following the line 
of the dark crown, and gradually also narrowing 
towards its termination ; chin black. The whole of 
the back is brownish black edged with yellowish 
brown, the edging becoming paler and more irregu- 
lar on the lower hack and rump. The shoulders 
are pale grey, quills brownish black; the greater 
covers dull greyish green, tipped with white ; the 
lesser covers white, forming a narrow bar above 
them. The great ornaments, however, to the bird, 
are the scapular feathers, which are long and lan- 
ceolate, deep black, shading into grey at their lower 
edge, and having a narrow distinct line of white 
running along the shaft. The breast almost to the 
centre of the belly is yellowish brown, the feathers 
with broad irregular waves of brown ; lower part 
of the belly white, the vent and under covers yel- 
lowish white waved and spotted with brownish 
black ; flanks white, distinctly waved with black, 
the feathers near the insertion of the tail having 
a broad tip of grey based by a deep black waving 
bar, the whole forming there a conspicuous cres- 
cented band.
