276 MESSRS. SCLATER AND SALVIN ON [Mar. 4, 32. HYPOCNEMIS 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. 33.

Supra fusca, loris albis, pileo vix rufescente ; interscapulii, alarium et secundariorum plumis nigro notatis et limbo angusto pallide rufescenti-ochraceo terminatis : subtus paulo dilutior, gula tota pure alba : rectricibus in pogonio interiore albo quater transfasciatis et hoc colore anguste terminatis pedibus schistaceis: rostro superiore corneo, inferiore albido long, tota 5*5, alee 3, caudce 1*8. 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 oi Pithys. In form and colour it somewhat resembles P. bicolor, but bas a restricted white throat, and distinct lunate markings above. The female of II. pcecilonota, which we have recently obtained, is of a uniform rich brown on the bead and body below.
