 lengthened mark of white. This 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 back 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.
