Species of the Genus Sycalis. 43 



sidered by Von Pelzeln to be the true Emberiza brasiliensis of 

 Gmelin ; but this is, to say the least of it, very dubious, and 

 contrary to the opinion of nearly every other writer. 



Under these circumstances I was intending to adopt the spe- 

 cific name Jiava for this bird (ex Passerina flava, VieilL), when 

 I observed that this term is applied by Mr. G. R. Gray* to 

 Si/calis flaveola (ex Fringilla flava, Miiller). Thus it would only 

 cause confusion to attempt to use Vieillot's name ; and I there- 

 fore propose to call the species Sycalis pelzelni, after our excel- 

 lent Honorary Member Herr A. v. Pelzeln, who, according to 

 my belief, misapplied the term hrasiliensis to it. 



It must be observed that while the male of this Sycalis much 

 resembles the corresponding sex of S. flaveola, the female is very 

 different, having the whole upper surface striated, and no yellow 

 on the breast and crissum below.

Similis >S^. flaveola, sed minor, dorso viridescenti-flavo, striis 

 nullis, et remigum marginibus internis albidis flavo tinctis 

 neque aureo-flavis : long, tota 4*3, alse 2"3, caudse 1*5. 



Hab. Venezuela, Guiana, and Lower Amazonia.

This species is very closely allied to S. flaveola, but may, I 

 believe, be distinguished in every stage by the inner margins of 

 the remiges being quite narrow and of a pale yellowish white, 

 instead of bright yellow as in S. flaveola. The difference is 

 still more appreciable when the upper surfaces of the primaries 

 in the two species are compared. It is also smaller, and in the 

 adult male shows no striations on the back. 



Nattererian skins agree well with the specimens registered as 

 of this species in my American Catalogue. But the locality of 

 " Trinidad " there given may be erroneous, resting only on a 

 dealer^ s authority.
