This bird appears to belong to a species different from any of the 

 four previously known members of this peculiar genus, concerning 

 which Sclater has written (P. Z. S. 1860, p. 467). It may possibly 

 also occur in Cayenne, but we have not yet met with any species of 

 the group from that countr3\ 



121. Iodopleura isABELLiE, Parz. 



Rio Tocantins. We should rather have expected to meet with 

 /. laplacii of Cayenne here. M. Parzudaki states that his type of 

 I. isabellce was procured on the Venezuelan Rio Negro ; and the 

 species also occurs in the Upper Amazonian district. 



122. Pipra FiLiCAUDA, Spix. 



"Found in the wooded islands of the lower Rio Negro, on the lower 

 boughs of the forest-trees." — A. W. 



123. Pipra flavicollis, Sclater. 



Mexiana and north side of the Amazons. This form, which is 

 hardly separable from P. aureola of Cayenne, was originally described 

 by Sclater fi-om specimens of Mr. Wallace's said to have been from 

 Barra, but more probably from the same locality as the present 

 skins. 



124. Pipra fasciata, Lafr. et D'Orb. 

 Rio Tocantins. Another Perirrinn form.
