Whether this Tanager is really the " Lindo precioso^' of Azara, is 

 not, I think, quite certain. I cannot reconcile it very satisfactorily 

 with his description. It would appear, however, to be the bird 

 called " Tanagra cayana" by d'Orbigny, and identified by him with 

 Azara's species, as far as we can judge by the characters given in the 

 ' Voyage dans I'Amerique Meridionale.' The author there says 

 that he met with this bird in the month of July in the gardens of the 

 city of Corrientes on the orange-trees. 



Prince Maximilian of Wied includes this Calliste among the birds
