aid to be from Para, but with no original label. As Wallace collected also on the 

 Rio Negro and on the island of Mexiana, a mistake with regard to the locality 

 might have occurred. Anyhow, there is no proof as yet that P. erythrocephala is 

 found south of the Amazons, where P. rubrocapilla evidently takes its place. 



8. Chiroxiphia pareola pareola (Linn.) 



Cfr. Nov. Zoul. xiii. p. 363. 



No. 653. t? ad. 28. iv. 06. " Iris dark brown." Identical with Pari examples. 



9. Sittasomus amazonus Lafr. 

 Siltasomus amazonus Lafresnaye, Bee. Hag. Zool. 1850, p. 590 ("ad summum Auiazonum"). 



No. 618. ? ad. (erroneously marked " 3 "), Obidos, 4. iv. 06. "Iris brown." — 

 Wing 72 ; tail 75 ; bill 14 mm. 



Agreeing perfectly with specimens from British Guiana and the Caura valley, 

 Venezuela. Typical Upper Amazonian skins are not available for comparison.

This specimen agrees perfectly with our large series from Surinam, Cayenne 

 and the Orinoco region. The upper mandible (in the dry skin) is uniform blackish, 

 the under parts are fulvous brown, and the light stripes on the foreueck and breast 

 have very distinct blackish margins. 



U. g. guttatoides (Lafr.) [= rostripallens Des Murs] has the upper bill partly 

 pale-coloured ; the lower surface is much more rusty, and the dusky margins to the 

 feathers of the foreneck and chest are much less distinct. The specimens collected 

 by Natterer near Manaos and on the upper Rio Negro belong to this form. 



U. g. sororia is new to the Brazilian avifauna.

 et Barra do Bio Negro; Xeberos. — We accept Barra '!■> Rio Negro as typical locality). 



No. 647. <$ vix ad., 21. iv. 06. " Iris light grey, feet grey, bill greyish black." 

 Differs from specimens collected by Natterer on the Rio Negro, only by its 



somewhat larger dimensions and by having both the upper and under parts of 



a rather darker grey. 



This species seems best placed iii the geims Dysithamnus, near D. schistaceus, etc.
