cited in the synonymy abo\'e, may apply to this form or perhaps to 

 T. VI. mclancholicus, but as neither Spix nor Svvainson gave sufficient 

 information in regard to the type-locahties in Brazil, it would be 

 necessary to examine and compare the types in order to determine to 

 which of the two forms these names properly belong. In the plate 

 representing M. furcaia the chest-band is very wide and dark, more 

 like that of true melancholicus, but Hellmayr (Abh. K. Bayer, akad. 

 wiss., 190(), 22, abt. 3, p. 666) says the type does not differ from a 

 much worn specimen from Paraguay, aufl tliat the chest and back are 

 shown much too green in the plate.

Remarks. — This form is readily distinguishable by its whitish 

 throat and very much yellower chest-band. In birds from Pearl 

 Islands, Bay of Panama, the belly is, as a rule, of a deeper shade of 

 yellow, sometimes even distinctly orange; but this character is not
