front of the tarsus and toes. 
Top of head, nape, and long occipital crest blackish slate, pervaded with an ashy hue ; face, over the eye, hind neck 
and its sides cinnamon-rufous, pervaded near the edges with ashy, and more particularly on the cheeks ; inter- 
scapular region, scapulars, wing-coverts, and tertials duller rufous than the hind neck ; the feathers mottled with 
obscure slaty, this being almost absent on the interscapulary part, which is pervaded with bluish ashy ; lower 
back and tail ashy brown ; primaries, winglet, and secondaries blackish slate; terminal portion of primaries and 
secondaries dull rufous ; primary-coverts brighter rufous, tips of three first primaries and two outer winglet- 
feathers white ; chin and gorge white, blending into the ashy fulvous of the fore neck ; the plumes of the 
throat and middle of the lower neck for the most part white on one web and more or less black on the other, 
marked with rufous and buff, on the first-named part these are mostly concealed ; feathers of the chest mostly 
white down the centre, surrounded by rufous or fulvous which is clouded with black ; on the breast the white

Female (Nicobars). “ Iris greenish yellow ; upper mandible horny brown, edged with dull green ; lower mandible 
greenish horny ; legs and feet dull green, claws horny. Differs from the male in having no line of dark spots 
dow-n the centre of the chin and throat, in having no feathers of the crest as dark as in the male, and in having 
several of them, and amongst others the longest, a sort of purplish red instead of black ; the whole mantle is 
somewhat paler, and the quills are markedly slaty ; the barrings of the wing-lining, sides, &c. are much less 
conspicuous and less tinged with ferruginous ; the ground-colour of the breast is more of a fawn-colour tinged 
with ferruginous, and there is much more white about the abdomen, and this is less rufescent than in the male.”
