82 ON PSOPIITA VIRimS AND PS. OBSCURA, 



no means » bright purplish reflections" as described by 

 Dr. Sharpe. 



Psophia viridis Spix (Av. Bras. 11, 1825, p. 66, tab. 83), 

 of which we possess no specimen, is, judging from 

 descriptions , an allied but decidedly distinct species. W. 

 Blasius ') in his review of the species of this genus says: 

 »die Federn des ünterhalses stark metallisch kupferfarbig 

 und hauptsachlich violettglanzend" which is not the case 

 in Ps. obscura. And besides »der Rücken, die verlangerten 

 weichen Schulterfedern grün , rait llostfarbe vermischt", it 

 does also not answer to our specimen of Ps. obscura , 

 which has the feathers of these parts (the back and shoul- 

 ders) only margined with green , and therefore only shining 

 with green in certain lights.
