This last species has the tail more graduated than the other 

 species of the genus, in which respect it evinces an approach to 

 the succeeding groups which now come before us, in which the 

 lateral tail feathers are much shorter than the middle. 



The second portion of M. Brisson's Icteri, or those which have 

 the base of the upper mandible narrow and angulated, and which 

 compose M. Daudin's genus Icterus^ are again diviseable into 

 two departments which M. Cuvier has formed into genera.* In 



* It appears to me that we must altogether reject the names which M. 

 Vieillot has assigned to the genera into which he has separated the Icterus of 

 M. Daudin. In these genera he has merely adopted the divisions which M. 

 Brisson has jn some measure pointed out, by the trivial titles of Carmgesi
