western bird should have a separate name ; and we suppose it 

 to be Hemipipo tschudii, Cabanis (J. f, Orn. 1874, p. 99), 

 although it does not altogether agree with the description of 

 that species, which was drawn up from a bird that had been 

 preserved in spirits. 



PiPRA suAvissiMA, sp. u. (Plate I.) 



Pipra Serena, Cab. in Schomb. Reise n. Guiana, iii. p. 697 

 (nee Linnaeus)? 



Nigerrima, fronte cretaceo-alba, uropygio cseruleo, abdomine 

 laete aurantiaco ; rostro et pedibus nigris : long, tota 2*6, 

 alse 2'3, caudse 1*1, rostri a rictu 0*5, tarsi 0*7. 

 $ olivacea, pileo caeruleo vix induto ; subtus pallidior, abdo- 

 mine medio flavicante. 



Hab. Guiana Brit, in montibus ^'Merume^' dictis, et 

 Bartica Grove [Whitely). 



Obs. P. serendP valde affinis, sed fronte latius alba, abdomine 

 magis aurantiaco et plaga pectorali aurantiaca absente di- 

 gnoscenda. 



This pretty species evidently takes the place in British 

 Guiana of the Cayenne Pipra serena; but its points of 

 difference are well defined. As Mr. Whitely has sent a good 

 series of specimens, we conclude that it is not an uncommon 

 species in the district he visited. 



We have little doubt that it was this species, and not the 

 true P. serena, that Schomburgk met with near the Roraima 

 Mountains.
