scribed bird is unquestionably entitled to the same rank ; but 
as I do not feel satisfied that Mr. Gould’s bird should be so 
considered, I refrain from characterizing my specimen. Per- 
haps if the attention of ornithologists generally be directed to 
this matter, we may be able to learn if there is really existing 
a group of pink-throated Petasophore living in the interior 
of Columbia or Ecuador, of which these examples have alone 
reached Europe; for it has happened that specimens regarded 
by naturalists as dusus nature, from their unusual appearance, 
have eventually proved to represent very distinct forms ; and, 
mindful of this fact, I do not at present feel inclined to place 
P. coruscans among the synonyms of P. anais, nor bestow a 
name upon the other form, which future evidence may show 
ought to have been left undescribed. Better “learn to labour 
and to wait.”

Hab. Brazil. 
This, the longest-known species of this genus, represents it 
in the south-eastern part of South America. It is distin- 
guished from al] the other species chiefly by its white under 
tail-coverts. It is very common in Brazil, and apparently 
migrates between Bahia and Rio de Janeiro. 
PETASOPHORA DELPHINA. 
Ornismya delphine, Less. Rev. Zool. 1839, p. 44. 
Petasophora delphine, Gould, Mon. Troch. vol. iv. pl. 229; 
id. Intr. Troch. (8vo ed.) p. 125. sp. 254. 
Hab. Central America, Trinidad, Guiana, Venezuela, Co- 
lumbia, Ecuador, and Peru. 
This widely distributed species was first described by Lesson 
(l.c.). It is remarkable among the members of this genus 
by having its metallic colouring restricted to the throat and 
ear-coverts, the rest of the plumage being devoid of brillianey,
