I. — A Revision of the Species of the Genus Pipra. 

 By C. E. Hellmayr. 



(Plate I.) 



The characters of the genus Pipra of Linnaeus (Mus. 

 Adolph. Frid. ii. Prodrom. (1764) p. 22), the type of which, 

 by elimination, is Pipra aureola, are too well known to 'be 

 repeated here. Mr. Sclater, our latest authority on the 

 subject *, admits eighteen species, besides one subspecies. 

 While I quite agree that P.filicauda, P. cornuta, P. iracunda, 

 and P. cinnamomea ought to be separated generically, it seems 

 to me that two more species, viz. P. yutturalis and P. leucor- 

 rhou, should be excluded from the genus Pi/>ru. The narrow, 

 more or less shortened first primary and the slightly elon- 

 gated throat-feathers clearly indicate their close relation 

 to Chiromachairis, and I think that they are better placed 

 in a separate genus, of which the proper name is Corapipo 

 Bonap. 



Thus restricted, the genus Pipra forms a fairly natural 

 group consisting of 19 species and 6 subspecies. Perhaps 

 /'. oirescens and P. stohmanni are the most aberrant
