DEFINITIONS

APHANTOCHROA
(Trochilidae; Ϯ Sombre Hummingbird A. cirrhochloris) Gr. αφαντος aphantos  obscure  < negative prefix α- a- ; φαντος phantos  visible  < φαινω phainō  to show; χροα khroa, χροας khroas  appearance, colour  < χρως khrōs, χρωτος khrōtos  complexion; "APHANTOCHROA CIRRHOCHLORIS. Sombre Humming-Bird.   ..   While the greater number of the Trochilidae are characterized by a splendid style of plumage, there are others, as will be seen on reference to the present Plate, in which these features are wanting; to most persons these sombre-coloured birds will be less pleasing than their more gaily attired congeners, but they are equally interesting in the eyes of the naturalist.  In its general structure, this simply attired bird, which I believe is never adorned with any luminous colouring, offers a considerable alliance to the Campylopteri; but as the peculiar dilatation of the shafts of the outer primaries is entirely absent, I have separated it from a group of which I formerly considered it a member, and have made it the type of a new genus—Aphantochroa." (Gould 1853); "Aphantochroa Gould, Monogr. Trochil., pt. 6, Sept. 1853, pl. [14] and text [= 2, pl. 54 of volume].  Type, by original designation and monotypy, Trochilus cirrochloris Vieillot." (Peters, 1945, V, p. 80).
