a Venezuelan specimens are included in the range of this form by Chrpman (Auk, 

 xiv, 1897, 369) and those from Trinidad by Hellmayr (Novit. Zool., xiii, 1906, 27); 

 but I can not agree to this. Phelps' specimens from Cumanacoa and San Antonio, 

 Venezuela, are before me, and while they certainly are not typical P. p. nigcr, they 

 are, in my judgment, nearer that form than P. p. dnereiventris. All of a considerable 

 series from Trinidad are certainly much nearer to the former than to the latter. A 

 single specimen from Bonda, Santa Marta, Colombia, is precisely like Venezuelan 

 specimens in coloration, all the others examined being typical dnereiventris. In 

 other words, while these dark colored birds from Trinidad and Venezuela very likely 

 are not true P. p. niger, as Hellmayr insists, they certainly are not the same form 

 as the "common run' ' of Colombian birds (precisely like those from Panama and the 

 Pacific slope of Costa Rica and Nicaragua) which we have been accustomed to call 

 P. dnereiventris. Evidently, therefore, if, as Hellmayr states, the type of P. dne- 

 reiventris agrees with the Venezuela and Trinidad si)ecimens it will be necessary to 

 give a new name to the form which I here call P. p. dnereiventris.
