276 MESSRS. SCLATER AND SALVIN ON [Mar. 4, 



32. Hypocnemts pcecilonota, Cab. ; Scl. Cat. A. B. p. 187. 

 The skin thus determined by us (P. Z. S. 1866, p. 186) is not of 



this species (see Pithys lunulata) ; but H. pcecilonota vera also 

 occurs on the Upper Amazon. Sclater has a skin from this locality, 

 and we have seen others.

 Hab. Peruv. orient., Sarayacu (Bartlett). 



This skin from Sarayacu, which we formerly referred to the female 

 of Hypocnemis pcecilonota, is certainly not of that species, but 

 probably the female of a new species of Pithys. In form and colour 

 it somewhat resembles P. bicolor, but has a restricted white throat, 

 and distinct lunate markings above. 



The female of H. pcecilonota, which we have recently obtained, 

 is of a uniform rich brown on the head and body below.
