This widely distributed species is subject to considerable local 

 variation, and at one time I thought it possible to separate the 

 Central-American form as C. gtuitemalensis ; but Messrs. Salvin and 

 Godman (J. s. c.) have shown that examples from Guatemala and 

 Guiana cannot always be distinguished. Most specimens from 

 Colombia, Ecuador, and Peru have a strong bluish cast on the body 

 below. Cassin (Pr. Ac. Sc. Phil. 1864, pp. 267, 268) has described 

 four "varieties " of this species from different localities under the 

 names " spiza," "• gua'.emalensis" ^^ccendescens," and '"'■ mclanopus." 



I cannot myself recognize more than three local forms :— (1) gua- 

 temalensis, extending from Guatemala to Panama and Western 

 Ecuador — a larger bird, of a lighter green ; (2) ccerulescens, with a 

 strong bluish tinge, from Colombia, Eastern Ecuador, and Peru ; 

 and (3) typica, from Trinidad, Guiana, and S.E. Brazil, rather 

 smaller, and intermediate between the two. But I confess that I 

 could not undertake to separate some of the third series from those 

 of the first.
