and a long time will probably elapse before we are made acquainted with the peculiar purpose for which 

 its curiously-formed bill is adapted. 



M. Bourcier considers that the Ornismya awcetta of M. Lesson is the young of this species ; in which 

 opinion I coincide ; but I believe that the specimen from which M. Lesson's figure was taken had the tail 

 of some other species surreptitiously appended to it instead of its own. 



M. Bourcier informs me, that the Amcettula recurmrostru is found in Cayenne, that it is rare there, and 

 that the chasseurs only meet with it in the interior of the great forests, where it lives isolated. 



The male has the whole of the upper surface, abdomen, and under tail-coverts golden green ; throat and 

 breast shining emerald-green ; down the centre of the abdomen a stripe of black ; wings dark purplish 

 black; thighs white; two centre tail-feathers greenish blue, the remainder coppery brown, margined on the 

 basal half of the external web with bronzy green ; under surface of all the tail-feathers rich, shining, fiery 

 copper colour ; bill and feet blackish brown. 



At a younger age the colouring of the body and wings is very similar, but the tail is bronzy purple, 

 tipped with white. 



In another state, which may be that of the female or a young bird of the year, the centre of the throat 

 and abdomen is brownish black, bounded on each side from the angle of the mouth with an irregular streak 

 of white; the tail dark purple, glossed with green, and the lateral feathers, particularly the outer ones, 

 largely tipped with white. 



The figures represent a fully adult male and a female, or young bird of the year, of the size of life. The 

 plant is the Tweedia verakolor.
