T he p re s e n t b ird is also o n e o f th e white-booted species o f Eriocnemis, and has th e u n d e r tail-coverts b lu e ;
it is d istin g u ish ed lu rth e r by its d a rk blue tail, and th e co p p e ry reflections on th e u p p e r surface.
It was discovered by Mr. Jelski in Central Peru, at Maraynioc, in June and August 1871, and was
described by Dr. Taczanowski, who says that it is nearly allied to my E . cupreiventris, but, besides other
differences o f coloration, it has a longer and stouter bill, a shorter and less forked tail, and considerably
longer tail-feathers.
I copy the following description from Mr. Elliot’s ‘ Synopsis of the Humming-Birds : ’—
Adult. Upper parts bronzy green, passing into pure green on the rump and upper tail-coverts ; wings
purplish black ; under surface glittering green ; under tail-coverts shining sapphire-blue ; tarsal tufts white ;
tail dark blue ; bill black. Total length 4 i inches, wing 21, tail 2, bill along the gape l i .
