Agyrtria bartletti

Bartlett’s Emerald

This species was discovered by Mr. Edward Bartlett on the Lower Ucayali River in Eastern Peru.

It belongs to the same section of the genus Agyrtria as A. neglecta, having, like that species, the throat and upper part of the breast blue, but it differs from it in having a blue-black tail.

The following is the original description:—

Crown of the head, nape, and back deep grass-green, changing to bronzy green on the upper tail-coverts; throat and chest rich blue; flanks green; centre of the abdomen greyish white; under tail-coverts bronzy brown, margined with grey; tail bluish black, the upper surface of the two central rectrices washed with green, and the four outer feathers on each side obscurely tipped with grey in those specimens which, according to Mr. Bartlett, are females; wings deep purplish brown; upper mandible brownish black; under mandible flesh-colour; feet dark brown.

Total length 3\(\frac{7}{8}\) inches, bill 1, wing 2\(\frac{1}{4}\), tail 1\(\frac{1}{4}\), tarsi \(\frac{1}{4}\).

We are indebted to Messrs. Salvin and Godman for the loan of a male specimen, from which the three figures in the Plate have been drawn.
