This bird differs from C. luscima Salv., from Veragua and Panama, 

 in grayish and distinctly spotted and barred chin and throat, much 

 brighter colored and very distinctly marked under-surtace of the body; 

 darker, more castaneous, and distinctly marked upper parts, and large 

 size. It is beyond qnestiou more closely related to G. philomela ScL., of 

 Guatemala, but differs decidedly in the characters pointed out above.

Habitat— Vannum. (Type, ^^o. 53800, S ad.; J. McLeannan.) 

 This species differs so conspicuously from B. susurrans (Jard.), from 

 Tobago, that a comparison is scarcely necessary.
