Adult male. Upper surface golden green, upper tail-coverts 

 rather brighter, crown duller ; under surface glittering yellowish 

 green ; under tail-coverts white with green discs ; tail bluish green, 

 tipped with white, the base of the outer web of all the feathers 

 whitish, this colour in the outermost pair meets the white tip ; bill 

 blackish, the middle of the culmen and the mandible (except the 

 tip) flesh-colour. Total length about 4-2 inches, wing 2-2, tail 1-5, 

 bUI 1 (Roraima). 



Young male. Under surface fawn-colour, a median line of glitter- 

 ing green feathers on the throat, outermost rectrix nearly white ; bill 

 black. 



There is a good deal of variation in the length of the bill in 

 this species, and also in the colour of the central rectrices as well as 

 acuteness of the outer ones. The latter characters seem to vary 

 with age. P. leucochlorus, Heine, was based upon Venezuela speci- 

 mens ; P. thaumantias virescens, Berl., upon Bogota examples, I do 

 not think either can be definitely separated.
