I quite agree witli Mr. Rirlgway in considering this species 

 totally different from P. niger cinereiventris Sol., with which 

 Dr. Sclater later united it. In fact, P. dorsalis appears to be 

 the Western representative of P. margiyiatus Licht. * It may, 

 however, readily be distinguished in the male sex by the uniform 

 black upper back, separated from the glossy black pileum by a 

 very broad, light cinereous nnpe-band. The wings and tail are 

 longer, and the bill decidedly larger. 



The female, as yet undescribed, is very much like tliat of 

 P. marginatus, but has a. larger, broader bill, and the pileum is 

 dark olive, each feather with an apical spot of dull greenish' 

 black. 



In addition to the type and another specimen in the British 

 Museum, I have examined four more adult males from Bogota in 

 the collections of the Munich Museum and of Count Berlepsch. 

 The Tring Museum possesses specimens from Paramba, N.W, 

 Ecuador, which are perfectly similar to Bogota skins. 



P. dorsalis thus ranges from Panama through Western 

 Colombia to N.W. Ecuador.

The series is exactly like specimens from Western Ecuador, 

 while skins from Central America (Costa Rica, Guatemala), as 

 a rule, are of a deeper rufous-tawny on the upper parts. 



P. cinnamomeus ranges from Southern Mexico (Tabasco) and 

 Guatemala southwards to Western Ecuador t.
