Remark. — This species belongs to that section of the Pha'ethorni- 

 thes to which Prince Charles L. Bonaparte has given the generic 

 appellation of Pygmornis ; in other words, it is allied to the 

 P. eremita^ pygmceus and griseogularisy but differs from all in the 

 absence of any red on the rump, and in the green colouring of the 

 base of the tail.

Remark. — This species differs from both P. pygmceus of Spix and 

 P. eremita in the rich bronzy colouring of its upper surface, in the 

 greater breadth of the black pectoral band, the deep bronzy hue of 

 the tail, and the small size of its short and rounded wings.

Remark. — This is also one of the smaller species, which, like P.

 Pygmornis. It differs from all others yet known in its darkly coloured 

 throat and under surface.
