This is found with T. c. nesophilus on the upper Orinoco from above 

 the falls, and is there the more common of the two forms. 



Thraupis palmarum melanoptera (Sclater). 



Tanagra melanoptera Scl., P. Z. S. 1856. p. 235. 



Tanagra palmarum melanoptera Berlepsch & Hartert, p. 20. 



The Asulejo ordinario as this species is known to the Venezuelans 

 is equally common and often in company with T. c. nesophilus. 



In fresh birds the eye is seal brown; bill black; feet slate grey. 



Specimens from above the falls of Atures^ are heavily washed 

 with violet both above and below, and the tarsus averages shorter 

 than in specimens from Trinidad and points on the middle and lower 

 Orinoco. In the American Museum are specimens collected by 

 Klages at Ciudad Bolivar, in June, July, August and December, and 

 at Maripa on the Caura River in May. 



1 Four specimens, two males and two females examined, collected in December, January and March.
