Show 1867.] THE BIRDS OF THE LOWER AMAZONS. 579 116. HADROSTOMUS MINOR (Less.). Examples of both sexes from Para. 117. PACHYRHAMPHUS CINEREUS (Bodd.). Island of Mexiana and Para. 118. PACHYRHAMPHUS POLYCHROPTERUS (Vieill.). Mexiana. 119. LIPAUGUS CINERACEUS (Vieill.). Para. Agreeing with Cayenne skins. One skin has light rufous edgings on the wings, and is probably immature. 120. HETEROPELMA WALLACII, sp. nov. Pallide olivaceo-virens, fere unicolor, alis caudaque extus brun-nescentibus : subtus dilutior, pectore rufescente vix tincto, subalaribus einerascenti-fuscis; rostro nigricanti-corneo, ad basin pallescente: pedibus pallide fuscis. Long, tota 6*3, alee 3*5, caudee 2*6. Hab. in vie. urbis Para (Wallace, May 1849). Obs. Aff. H. amazonum ex fl. Amazonum superiore et ejusdem formee et staturee, sed corpore supra magis virescente, nee rufo tincto, et gula et abdomine pallidioribus et magis cinerascentibus diversa. 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 country. 121. IODOPLEURA ISABELLA, Parz. Rio Tocantins. W e should rather have expected to meet with J. laplacii of Cayenne here. M. Parzudaki states that his type of L. Isabella; 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 from specimens of Mr. Wallace's said to have been from Barra, but more probably from the same loeality as the present skins. 124. PIPRA FASCIATA, Lafr. et D'Orb. Rio Tocantins. Another Peruvian form. |
