as deep yellow as P. s. maximiliani, while the ? from Goyaz (No. 1847) has the 

 under parts much paler, clear citron-yellow. 



I hope to discuss the geographic races of the P. sulphuratus group on 

 another occasion.

[Though not collected by Mens. Baer, I take this opportuuify of recording the 

 following species, of which there is an example in the Paris Museum. 



78. Onychorliyndius swainsoni (Pelz.). 



Muscivora Sioainsoni Pelzeln, Sitz. Akad. Wisseiisch. Wieii (math, naturw. CI.), xxxi. p. 326 (1858. — 

 " Insel Juan Fernandez '' — errore ! We substitute S. E. Brazil). 



Cat. No. 1846, No. 871. <S (jr.), Villa Boa (= Goyaz), 1844. « (Eil d'nu gris 

 clair." Collector's number 238. Obtained by Castelnau and Deville. — Wing SI ; tail 

 691 ; bill 20| mm. 



This bird agrees exactly with several Rio-skins in the Triug and Britisli 

 Museums. The range of this species is still very imperfectly known. It was 

 sujijiosed to be a native of South-eastern Brazil (and I have seen many skius 

 of the unmistakable " Rio-make " in various collections), but the only precise 

 locality recorded up to the present day was Neu Freiburg (state of Rio de 

 Janeiro), where Burmcister * got some specimens.] 



79. Hirundinea bellicosa (VieilL). 



Tyramms bellicosus Vieillot, Xouv. Did. xxxv. p. 74 (1810. — ex Azara No. 189 : Paraguay).

The series differs from several South Brazilian (S. Paulo) skins by having 

 the feathers of the crown not so blackish and conspicuously, though narrowly, 

 edged with pale rusty or rufescent brown.
