@ Seven specimens. 
6 I am able to distinguish females of this species from those of C. massena (both 
occurring together on the Isthmus of Panama) only by its smaller and relatively nar- 
rower bill. The coloration seems to be precisely the same except this, the bill is 
more yellow (less orange). 
¢ Three specimens.
