 Jlavo. 

 This beautiful species, figured by Lesson in his Centurie Zoolo- 

 gique, pi. 68, considerably resembles the several bliie species of 

 Tanagra, often confounded with the T. episcopus, L., on account of 

 their similarity to it ; I mean the T. archiepiscopus, Desm. ; T. Sayaca, 

 L. (T. glauca, Sparrm) ; T. oUvascens, Licht. (erroneously taken for 

 the female of the T. Sayaca) ; but the beautiful goldfinch-like yellow 

 spot, which it bears at the base of the primaries, as well as the 

 blacker and much more robust bill, almost bullfinch-shaped, distin- 

 guish it from them all.

As the chief difFerence bet^'een this bird and the Silens consists 

 in its greater dimensions, I subjoin them : 



Long. tot. 9" &" ; rostr. 1" ; ai. 4" 6"' ; caud. 4" 6'^' ; tars. I".

An important addition to the genus Icteria, ■which hitherto com- 

 prehended only one species, the Pipra įjolyglotta of "VVilson, Icteria 

 viridis, ^'^ieill., from which it difFers in the more intense, almost 

 orange-colour of the breast, and by the whiteness of the under man- 

 dible of the bill, -vvhich is entirely black in the viridis. I. viridis 

 may stand characterised as follows : 



r. viridis, pectore Jlavo ; rostro ex toto nigro.
