* Linnaeus' nomenclature of this bird is full of errors. In the tenth edition he named a Paws pipra 

 (p. 190, hab. "in Indiis ! "), with the same diagnosis (*' P. *ater capite supra albo ") which he gives for 

 his Pipra leuciu-illa in the Prodr. Mux. Ad. Fridr. \\. p. 33, while the diagnosis in the Prodr. for Pipra 

 IcucocepJuila is '* P. nigra capite albo," and he quotes .Soba (ii. p. 102, t. 96 f. 5), who apparently described 

 the northern form of our Pipra lencocilla. Unfortunately, however, Linnaeus adds a more detailed 

 description (" Statura Motacillae, similis sequenti, sed rostrum paulo vaHdius. Corpus totum nigrum. 

 Caput totum album. Vibrissae ad os. validiores quam in congeneribus "), which seems to be referable to 

 Arundniicola Icncoccpliala, and which corresponds with the description of Pipra leucocephala (= Arundi. 

 nicida Icncttcephala) in the Prodr. Mus, ad. Frid. ii. p. 33. The quotation from .Seba appears in the 

 Prodroimts as a synonym of Pipra Inicocephala. 



It follows th.at Parux pipra L. is a " mixtum compositum '* of Pipra lencocilla and Arundinicola 

 leucocepfiala, and therefore cannot be used as a name for one of these two species.
