Hitherto I have entertained the opinion that the H. jacula and the Leadbeatera grata were of the same form; but upon further consideration I now believe them to be distinct; and as the former is the type of my genus Heliodoxa, I retain that of Leadbeatera for the other.
Of this form I possess three very distinct birds, which might be considered by some persons as one and the same, but in this opinion I cannot agree: the L. Otero from Bolivia, and the L. grata are too unlike to be considered otherwise than as separate species; while the third, which is from Venezuela, is allied to the Bolivian bird rather than to that from New Granada.

Centre of the crown brilliant blue, bordered on each side with jet-black; upper surface bronzy green; wings purplish brown; two centre tail-feathers bronzy, the remainder black; under-surface glittering green; under tailcoverts olive-grey; bill black; feet dark brown.
Total length, 5\(\frac{1}{2}\); inches; bill 1\(\frac{1}{16}\); wing 2\(\frac{7}{8}\); tail 2\(\frac{1}{4}\); tarsi \(\frac{1}{4}\).
This species is very nearly allied to the Leadbeatera Otero, but it differs in having a straighter and shorter bill, and in the green tint of the under-surface.
