138 COTINGIDA. 
All the variations in the wings of the various species of Cotinga, where they occur, 
appear to be found in the male alone, the wings of the females being of normal 
structure, except, perhaps, in the female of C. ridgway?, in which (we have only one 
immature specimen) the first and second primaries are abnormally narrow, though 
much less so than in the adult male. 
Using the structure of the primaries as a chief character with others whereby to 
define the members of the genus Cotinga, the following key may be useful :—
