Several specimens of tliis species were obtained by Mr. 

 Whitely in the Merume Mountains. It belongs to the same 

 section of the genus as M. tyrannulus, in which the tail is 

 without any rufous edging ; but the dark colour of the back 

 renders it easy to be recognized. From M. apicalis it differs 

 in wanting the light apex to the tail. 



PiPRA VIRESCENS, Pclz. 



We are indebted to Count v. Berlepsch for drawing our 

 attention to the bird described by Sclater and Salvin as Ty- 

 ranneutes brachyurus, and for the suggestion that it might 

 prove to be Pipra virescens of Pelzeln. On reexamining our 

 specimens we find that this surmise is quite correct. In 

 Mr. Sclater^s and our own collections are four specimens of 

 Pipra virescetis, one of them a type from the Vienna Museum, 

 and the others obtained by Mr. E. Bartlett on the Upper 

 Amazons. None of these specimens have any traces of the 

 yellow vertex ; so we must presume that they are all imma- 

 ture. Mr. Whitely^s examples of Tyranneutes brachyurus 

 are marked as of both sexes, but all have the yellow vertical 

 spot. As they do not differ in any other way from our spe- 

 cimens of Pipy^a virescens, we conclude that the possession of 

 this yellow vertical spot is a mark of maturity, and that those 

 birds in which it is absent are still immature. Anyhow we 

 have no hesitation in placing Tyranneutes brachyurus as a 

 synonym of Pipra virescens.
