The species that remain of M. Cuvier's Icterus are distin- 

 guished by a somewhat slender and arched bill, and a graduated 

 tail : in both of these latter particulars approaching the preceding 

 genus Quiscalus more closely than any other group of the sub- 

 family. The following appear to be their characters. 



Icterus. Cuvier. 



Rostrum subgracile, subelongatum, subarcuatum ; naribus 

 oralibus partim membrano tectis. 



Al(e subrotundatae : remigibus 2da , 3ti& , 4*3, et 5^ fere aequali- 

 bus longissimis. 



Cauda gradata, rotundata. 



Pedes subfortes. 



The following birds may be selected as the typical species of 

 this genus, and those of the most common occurrence.
