L. — Characters of a new Puff-bird of the Genus Nonnula. 



By P. L. SCLATER. 



Upon reexamination of the specimens of the PuflF-birds of 

 the genus Nonnula in my collection and that of Messrs. Salyin 

 and Godman, I find that two distinct species have hitherto 

 been united under the name N. frontalis. The former of 

 these (from the interior of Colombia and Panama) , distin- 

 guishable by its rufescent crown and cinereous sides of the 

 head, is closely allied to N. ruficapilla, and is legitimately 

 entitled to bear the nhmefrontalis. The latter (from Ecuador, 

 but extending northwards into Colombia, and southwards into 

 Peru), which has the whole cap brown, like the back, and no 

 cinereous on its sides of the head, may be called 

 ' Nonnula brunnea, sp. nov. 



Supra brunnea, fere unicolor, loris subrufescentibus ; alis et 

 cauda nigricantibus ; secundariorum et tectricum mar- 

 ginibus extus dorso concoloribus ; rectricum externarum
