Description. Bluish grey, paler below ; wings and tail blackish, edged with 

 greenish blue ; lesser wing-coverts dull greenish blue, like the edgings of the 

 wings ; bill plumbeous, feet brown : whole length 6'0 inches, wing 3-6, tail 2-7. 

 Female similar. 



Hab. S.E. Brazil and Argentina. 



In the ' Catalogue of Birds ' I referred the Argentine Blue Tanager 

 to T. cyanoptera, though expressing a doubt upon the subject. I am 

 now disposed to adopt Graf. v. Berlepsch's view that the Argentine 

 species rather belongs to T. sayaca. P. L. S. 



This species migrates as far south as Buenos Ayres, and appears in 

 spring, in small flocks or parties of three or four birds, in the woods on 

 the shores of the Plata. The male utters a series of peculiar squealing 

 notes by way of song.

Hab. South Brazil, Uruguay, Paraguay, Argentine Republic, and 

 Bolivia. 



The plumage of the male of this fine Tanager is rich blue above and 

 yellow beneath; the upper plumage of the female is a uniform dull 

 olive-green, the breast and belly buff-colour. 



It is a migratory species, which appears in Buenos Ayres in small 

 flocks in summer. Both sexes have a long, sharp, reedy call-note ; the 

 male also possesses a song composed of notes with a peculiar bleating 

 sound.
