The lašt three birds have the space round the eyes mere or less 

 denuded, and would form the snhgenus Phleffojjsis, Reichb., of which, 

 I bclicve, F. nigromaeulatus is the type. In that very peculiar 

 member of this family Pyriglena nudiceps (Myiothera niidiceps, 

 Cassin, Pr. Ac. Sc. Phil. v. p. 106. pi. 6), this formation is developed 

 to a still greater extent, the whole top of the head being naked.

This is a typical Conopophaga, vvith the characteristic white pencil 

 of feathers on the sides of the head. Trusting to Tschudi's identifi- 

 cation of a specimen collected by him, which is now in my coUection, 

 I had considered it to be d'Orbigny's C. ardesiaea. But upon exa- 

 mining the type of that species in the French National Collection I 

 found such was not the case. That bird does not possess the chest- 

 nut-brovvn cap or darker cinereous colour of the throat belonging to 

 the present species, but is more uniform in its colouring both above 

 and below. 



There is a specimen of this bird in the British Museum from Bo- 



M. O. des Murs, in the Ornithology of the Voyage of Castelnau 

 and Deville, has described and figured another Conopophaga, some- 

 what resembling the present C. peruviana, pi. 16. f. 1. But this 

 bird has spots upon the winga and a varied back. 



3. Hypocnemis elegans. 



Hypocnemis ?, Sclater, P. Z. S. 1855, p. 147. 



I have lately seen other specimens of this bird, and have one in 

 my own collection — a Bogota skin. Though closely alUed to H. me- 

 lanosticta, I cannot consider it othervvise than specifically distinct, 

 and therefore propose a name for it : I have already giren its cha- 

 racters in these Proceedings for 1855.
