Mr. H. Whitely discovered the present species in British Guiana, having met with it on Roraima and on the Merumé Mountains.
It is stated by Messrs. Salvin and Godman to be allied to A. viridiventris, but to differ in its less forked tail, cinnamon vent, and in the coppery cinnamon, instead of violet, colour of the tail; they found these characters quite constant in a considerable series of skins sent by Mr. Whitely.
The following is a translation of the original description:—
Top of the head and entire body below brilliant green, the back tinged with copper-colour; upper tailcoverts and tail dark cinnamon, washed with copper-colour; a patch on the flanks and the thighs snowy white; vent pure cinnamon without spots; upper mandible dusky, the base of the mandible pale for two thirds of its length. Total length 3·5 inches, wing 2·0, tail 1·15, bill from gape 0·8.
The figures in the Plate represent the adult male in three positions, and have been drawn from one of the typical specimens lent to us by Messrs. Salvin and Godman.
