Apparently inhabits the entire Tropical Zone of Colombia except the 

 arid coastal region from which it was described. Immature birds of both 

 sexes are slaty-gray washed with olivaceous above with a concealed white 

 dorsal patch; less olivaceous below with the throat and center of the breast 

 and abdomen streaked and margined with white. The adult female is 

 clearer and darker slate above, the underparts are much blacker and the 

 white markings are confined mainly to the throat. The adult male is jet 

 black above and below with no white marks on the body other than the 

 dorsal patch.

Apparently restricted to the Tropical Zone of the Pacific coast. Of 

 our ten specimens six sexed as "male," are wholly black, save for the con- 

 cealed dorsal patch, while the four sexed as " female " have also the throat 

 and breast and, to a lesser degree, the wing-coverts spotted with white.
