Notwithstanding the larger average size of specimens from Vera Cruz and Tamauli- 

 pas, I am not disposed to separate them, there being no color differences that I am 

 able to discern. 



Of the five Costa Rican specimens examined all are clearly intermediates between 

 this form and C. I. mesorhyrichus, and would be referable to the latter except for the 

 paler bill. It was possibly on a specimen of this character that Cabanis and Heine 

 based their supposed species.
