The species are as follows : 

 Scotothorus turdinus (Maximilian). 

 Seotothortis wallacii (Sclater and Salvin). 

 Scotothorus amazonus (Sclater). 

 Scotothorus stenorhynchus (Sclater and Salvin). 

 Scotothorus verce-jxicis (Sclater). 

 Scotothorus unicolor (Bonaparte). 

 Scotothorus fiavicapiUus (Sclater) . 

 Scotothorus chrysocephalus (Pelzelu). 

 Scotothorus igniceps (Sclater) . 

 Scotothorus rosenbergi (Hartert). 



METOFIA Svvainson. 



The terra Metopia Swainson' must be displaced on account of 

 Metojna Meigen,' a genus of Diptera. The proper name is Anti- 

 lophia Reichenbach. ^ 



The type and only species will therefore stand as 



Antilophia galeata (Lichtenstein). 



GYMNOCEPHALUS Geoffrey St.-Hilaire. 

 The genus Gymnocephaliis Geoffroy St.-Hilaire^ must give way 

 to Gymnocephalus Bloch and Schneider.^ In its stead may be 

 employed Perissocephalus, from -£p<.aa6<i, mirabilis, and y.sfakri, 

 caput. The type and sole species is Corvus calvus Gmelin, which 

 should now be called 



calvus (Gmelin). 



HETEKOCNEMIS Sclaicr. 

 Heterocnemh Sclater* is preoccupied by Heterocnemis Albers' for 

 a genus of Coleoptera. Since the only other name for this group 

 of birds, Holocnemis Strickland/ is untenable because of Holoc- 

 nemis Schilling/ in Coleoptera, as pointed out by Dr. Sclater 

 (^. c. ), it is proposed to substitute Sclateria, in honor of Dr. P, L.
