E. e. euleri differs from E. lawrencei by its rufous brown or russet (instead of 
greenish olive) upper parts, and much paler lower surface, nearly whitish in the 
middle of the abdomen. Natterer’s specimen from Borba belongs likewise to the 
present species. Its range is given by Berlepsch & Hellmayr in Journ. f. Ornith. 
1905. p. 23. 
With regard to EF. euleri argentinus (Cab.), 1 may mention that additional 
specimens from Argentine in the Tring and Munich Museums do not bear ont all the 
characters shown by the type (cf. doc. cit. p. 23). They are by no means smaller 
than ZF. e. euleri, but the upper parts are decidedly duller, less rafescent, and the 
belly is whitish with very little, if any, yellowish tinge on the flanks. An adalt 
male from Chuchurras, prov. Huannco, Peru (W. Hoffmanns coll.), in the Tring 
Museum, agrees in every respect with Argentine skins, while another from Pebas, 
N. Peru (Hauxwell coll.), in the British Museum, is undoubtedly referable to 
E. e. euleri! More material is required to establish the validity of this form or 
otherwise.

Similar, in coloration and size, to specimens from Mattogrosso (Chapada) and 
Northern Sao Paulo, The lower parts are white with the chest tinged with pale 
brownish grey, and the flanks very pale yellowish. Natterer obtained a young 
male at Borba, March 3, 1831, which does not differ either from Mattogrosso skins 
in corresponding plumage. 
E. f. bimaculatus ranges from Eastern Bolivia (Yungas) through Central Brazil 
(Madeira district ; Mattogrosso: Cayaba, Chapada *) east to Goyaz (city of Goiaz ; 
Rio Thesouras, Araguaya f) and south to the valleys of the Parana, Parandpanema, 
and Rio Grande in Northern Sao Paulo.t 
In Central and Southern Sao Paulo, however, the typical race, LE. /. fuscatus 
(Wied), is met with. I have examined a series from Ypanema, and examples from 
S. Sebastiaio, Ubatuiba, and Rio Feio. 
Snethlage’s record of E. fuscatus§ from Goyana, Tapajéz, is most probably 
referable to the pale, western race E. /. b¢maculatus.
