Terpsiplione nigriniitVata, Reichenow, , p. 110 (types ex- amined)*. Adult male. General colour above glossy steel-black; quills and tail black, edged with the same colour as the back ; sides of face, sides of neck, throat, and fore neck glossy steel-black : rest of under siirface light slaty grey, as also the under wing-coverts : thighs dusky brown ; quills blackish below, lighter brown along the edge of the inner web. Total length 6 inches, culmen 0-6, wing 2-5, tail 2-9, tarsus Bill and fout of Trorhirernis nitens. Adult female. Top of head (or crest) only glossy black as in the species of this group larger than either T. cyanomelas or T. nitens. Young of both sexes resemble the females of both the species just mentioned, but are of darker cinereous, and like them have the crest only black. The bill is larger and more depressed. I do not regard it as expedient to propose a new specific desig- nation in this difficult family, without having adult ; {Cassin, I. c.) * Dr. Peters was so kind as to send me for examination the types of Dr. Keichenows' T. nigrimitrafa ; and in the absence of typical specimens of Trocho- cereus nitens, I was inclined to consider them quite a distinct species. During a recent visit, however, to Leiden, I found several birds from the Gold Coast agreeing with Dr. Reichenow's specimens, and identified in that collection as T. nitens of Cassin. On re-examining the subject I consider this identification correct, and I also identify with the same species three specimens which 1 had before determined as the female of Tcrpfiphoyu afrochali/hea.
