Species of Birds from Bogota. 129 



Otherwise I cannot detect much difference between 

 B. simplex and B. elceoprorus ; but in one of my specimens of 

 the former, which seems to be more adult than the other one, 

 tlie back is of a much darker olivaceous, and the underparts 

 are of a more intense yellow than in my specimens of B. 

 elceoprorus.

Of this new species I have examined three males and one 

 female, proving that the characters expressed in the above 

 diagnosis are well founded. I have dedicated this bird to 

 Mr. Adolphe Boucard, of Paris, who kindly forwarded my 

 specimens, together with a large and interesting collection 

 received by him direct from Santa Fe de Bogota. All 

 these skins were of the usual Bogota make.
