 Wing 57A ; tail 48 ; bill 11 mm.] 



Tlie two specimens agree with the typical series from l?orl)a in the coloration 

 of the lower j)arts and in the olive-yellow loral streak, but difl'er liy their decidedly 

 brighter, pure grass-green (instead of yellowish green) upper surface. In this 

 respect they ajiproach R. f. eiridici'ps* from North Peru (Pebas) and Eastern 

 Ecuador (Napo). The latter, however, has the throat and chest distinctly light 

 green like the sides, uot clear olive-yellow as R. f. borbae. From both form.s, 

 B. f. Jatiirntris, of Easterii Brazil, etc., differs by having the lower parts, 

 especially the throat and chest, much deeper, gamboge-yellow ; the loral streak 

 more clearly defined, rusty yellow or orange; .and the n]]jier wing-coverts more 

 conspicuously edged with clear yellow. 



Characters and range of the three races are as follows : — 



(«) R. ^ffaviventris ^fiariventris (Wied). 



Hab. Eastern Brazil : Southern Bahia (Alcobara, Mncuri), Goyaz (Rip 

 Araguaya), Tocantins (Arumatheua), Tapajuz (Goyana).t N.E. Brazil : Forte do 

 Rio Briinco (Natterer). British Guiana, Venezuela, Trinidad, Tobago. North 

 Colombia (Santa Marta). 



Arlult. Upper parts bright yellowish green ; median and greater upper wiug- 

 coverts with well-defined, broad edges of deep olive-yellow. Lores and eyelid deep 

 rusty yellow or dull orange, conspicuously contrasted with the green of the crown 

 and yellowish green of the cheeks, etc. Under parts deep gamboge-yellow, throat 

 and chest often tinged with dull ochraceous. 



Wing 55 — 62 ; tail 47 — 55 mm. 



Examined fifty-one specimens from Brazil, Brit. Guiana, Venezuela, Tobago, 

 etc. Specimens from the Tapajoz and Tocantins Rivers are clearly referable to 

 R. f.Jiaxiceiitiis, though some of them slightly point towards R. f. borbae. I 

 am indebted to Miss Snethlage for the loan of the series contained in the Pani 

 Iilusenm. 



(b) R. fiavirentris borbae Hellm. 



Hub. W. Brazil : Borba, Marmcllos, on the Rio Madeira (Natterer, Hoffmanns) ; 

 Monte Verde, Rio Puri'is (Mus. Goeldi). 



Adult. Upper parts less yellowish green, sometimes (in Marmellos and Purus 

 examples) even pure grass-green. Median wing-coverts edged with green, like 

 the back ; greater ones with narrow, ill-defined, greenish yellow margins. Narrow 

 loral streak dull olive-yellow, rarely distinctly rusty yellow (in two from Borba). 

 Under parts pale olive-yellow, slightly darUiT on throat and chest. 



Wing 55 — 59 ; tail 47 — 5ii mm. 



Examined: five adults from Borba, including the types; one each from 

 Marmellos and I\Ionte Verde, Purus.

Hfib. North Pern: Pebas (ITanxwell ; tyi)e). Eastern Ecuador: Rio Napo 

 (Petit). [Central Peru : La Merced, ( 'hanchamayo (Kalinowskij.] 



Adult. Loral streak and upper wing coverts as in I'.f. borbae, but upper parts
