Agyrtria nitidicauda

Bright-tailed Emerald

Illustration not included in supplement volume

This species, which comes from Guiana, is said by Mr. Elliot to resemble A. nigricauda, but to differ in the colour of the tail.

The median pair of rectrices are golden green; the remaining ones with the inner webs black, except the tip, the outer webs metallic golden green; all the lateral tail-feathers are tipped with bright metallic golden green.

He further describes the species from the type in his collection:—

Adult. Upper parts bright bronzy green, with a slight coppery tinge on the head. Chin white. Throat, breast, aud sides of the neck bright metallic grass-green. Flanks and pbapiel dull green. Middle of abdomen, vent, and under tail-coverts pure white. Wings purplish brown. Bill flesh-colour (perhaps red in life), with a dark tip. Total length 3\(\frac{1}{2}\) inches, wing 2\(\frac{1}{8}\), tail 1\(\frac{1}{2}\), bill along culmen \(\frac{3}{4}\).
