The specimen named iodura in the Museum of M. Heine at Halberstadt is different from the bird so called in 

 the Museum at Berlin. The former has a glittering crown and light-lilac shining tail-feathers ; while the latter has 

 a dull-coloured crown, and the tail so nearly resembling that of P. viridigaster that I have no doubt of its being a 

 young bird or a female of that species. On the other hand, I think M. Heine's bird is a distinct species, and I 

 have therefore retained it under the term iodura,

 Habitat. Pacific side of Nicaragua ; Realjo ? 



The ErythronotcB are nearly allied to the PyrrhophcencB, As in that genus, the sexes are alike in their colouring. 

 The species are much more circumscribed in their habitat, being almost confined to Venezuela and the countries 

 immediately adjoining. 



The oldest-known species, which I have called antiqtia, appears to be subject to much variation in its colour 

 and markings ; but, as I stated in my account of that species, I have questioned the propriety of their separation 

 until we are better acquainted with them. 



Genus Erythronota, Gould, 



CEpvOpoy, ruber, et rcSros', dorsum.) 

 Generic characters.

 short and slightly forked ; tarsi clothed ; hind toe rather shorter than the middle one ; claws short ; throat and chest 

 lively green. 



Female. — Similar in colour.

Hemithylaca erythronota, Cab. et Hein. Mus. Hein. Theil iii. p. 37. 



Habitat. Trinidad, Tobago, and Venezuela. 



The birds from Tobago are very much larger than those from Trinidad ; and some of the specimens from 

 Venezuela have the under tail-coverts wholly chestnut ; I should have considered this indicative of another species, 

 had I not found a similar variation in specimens from Trinidad. 



353. Erythronota Felicia , Vol. V. PI. 317. 



Habitat, Venezuela. 



The O. Felicice is admitted by the French TrochiUdists to be distinct from O. antiqua, and as such I have kept 

 it; at the same time it is extremely difficult to distinguish one from the other. In size they are as near alike as 

 possible ; but the former has a bluer tail, and the back and upper surface destitute of the fiery-red colouring 

 observable in many specimens, but not in all, of the O. antiqua ; the under tail-coverts, too, are frequently stained 

 with violet. 



I have a specimen of this bird, presented to me by M. Emile Parzudaki, of Paris, with the name of Emile 

 attached. The bird was killed by him during his visit to South America.
