264 MESSRS. SCLATER AND SALVIN ON [Mar. 4, 



melas) was first described as new from specimens from this locality ; 

 but we bave since met with it from Venezuela and Cayenne, and are 

 doubtful whether older synonyms may not yet be found for it. 



1. Guiraca cyanea (Linn.). 



Guiraca cyanoides, Scl. & Salv. P. Z. S. 1866, p. 566 ; 1867, p. 750. 



Nauta, Lower Ucayali and Chyavetas (BartL). 



The Panama form of this species, to which Lafresnaye applied the 

 name cyanoides, is nearer to the Mexican G. concreta, or at all events 

 intermediate between it and G. cyanea. The Guianan and Ama- 

 zonian form is not specifically divisible from the S.E. Brazilian.
