This species, by not having any white band across the breast, and by having the 

 tail much forked, cannot remain in the genus Heliangelus, where it was placed 

 by Mr. Gould, but properly belongs to the present one, finding its natural position 

 between H. cxortis and H. harrali. The term Helijmus, proposed for it by M. 

 Mulsant, is entirely unnecessary, as the species possesses no characters that differ 

 gcnerically from the other members of Heliotrypha.

 metallic olive-green, silvery in some lights, margined with a line of black. Rest 

 of plumage of body shining grass-green, most brilliant on the breast. Wings pur- 

 plish-brown. Median rectrices bronzy-green ; lateral ones, blue-black. Under tail

Possessing no generic characters differing from those which characterize the 

 species of Heliotrypha, the term Nodalia of Mulsant is placed among the synonyms 

 as unnecessary. Description taken from the type in my collection.
