1867.] THE BIRDS OF THE LOWER AMAZONS. 575 



65. Dendrocolaptes cayennensis (Gm.); BuflP. PI. Eril. 621. 



Para, two examples, April and May 1849. 



Agreeing with Cayenne specimens of this species, but different 

 from the bird so named in Sclater's collection, which is from the 

 Upper Amazons, and is probably undescribed. 



66. Dendrornis ocellata (Spix). 



Dendrocolaptes ocellatus, Spix, Av. Bras. i. p. 88 ; D. guttatus, 

 ejusd. tab. 91. fig. 1. 



One example, obtained at Para, agrees with a specimen in Sclater's 

 collection, also from Para, collected by Natterer, and determined by 

 H. V. Pelzeln to be of this species. 



Q7' Dendrornis eytoni, Sclater. 



Para, agreeing with the type obtained by Mr. Wallace, on the Rio 

 Capim, in Sclater's collection. This species is closely allied to D. 

 rostripallens, Lafr. 



68. Dendroplex picus (Gm.). 

 Para. 



69. Xiphorhynchus trochilirostris, Licht. 



"River Amazons, north bank: $, eyes dark blue."

 One example, from the Rio Tocantins, Sept. 1848. 



72. Thamnophilus, sp. ? 



One example from the Amazons (1849), agreeing with a skin of 

 Natterer's in Sclater's collection from the Rio Negro, marked 

 " female " (no. 928). We do not know the male of this species. 



73. Thamnophilus nigro-cinereus, Sclater. 



Two males, from the Rio Tocantins and Mexiana, agreeing per- 

 fectly with Sclater's type specimen, which is also evidently one of Mr. 

 Wallace's skins.

 Specimens of both sexes from Para and Capim River. 



'^^5. Thamnophilus doliatus (Linn.). 

 Island of Marajo.
