DESCRIPTION 



Of a male, killed at Fort Franklin. 



Colour, velvet-black, with a reddish reflexion. Throat brownish. A broad white band 

 between the eyes, and a triangular patch of the same on the nape. Bill reddish-orange, the 

 unguis paler; a square black spot on the lateral protuberance. Legs orange ; webs brown. 



Form. — Bill much like that of Oidemia fusca, but the lateral protuberances are naked and 

 horny, and the central one is feathered farther down. The laminae are distant, and the lower 

 ones particularly prominent, with cutting edges. As in the other Oidemia, the bill and fore- 

 head are inflated, causing the head to appear lengthened and the crown depressed. The 

 nostrils are rather large, and nearer to the point than to the rictus. 



Female browner ; under plumage, in particular, paler ; back and wing-coverts narrowly 

 edged with grey ; breast, flanks, and ears, with some whitish edgings. Bill black ; its base 

 not so much inflated, and the nostrils smaller than in the male.
