'Three specimens. 



^Two specimens. 



'A specimen from Duefias, Vera Paz, Guatemala (no. 20424, male ad. , August 3, 1859, 

 0. Salvin) , is not only decidedly larger than an adult male from Chicharras, Chiapas, 

 but is decidedly grayer in its coloration, and the flanks are less tulvescent. It is in 

 worn plumage, however, while the Chiapas specimen has recently molted. Several 

 specimens from Guatemala, but of unknown locality, and with sex undetermined 

 agree with Chiapas specimens.
