Quite possibly those of the above references which pertain to localities on the east- 

 ern slope of the Andes (eastern Peru, etc.) may belong to P. r. rubinus, or at least not to 

 P. r. heterurus; and it may also be that the Colombian bird is not the latter form. I 

 have neither the material nor time, however, necessary to the proper elucidation of 

 the extralimital forms of the genus.

 coll. Count von Berlepsch.). 



An adult male in the collection of the American Museum of Natural History, from 

 Guayos, Venezuela, agrees minutely with Berlepsch and Hartert's description, and 

 the form is exceedingly well characterized. Other Venezuelan localities mentioned 

 by the authors cited are Puerto Cabello, Cumana, Ciudad Bolivar, Suapure, and La 

 Pricion. It would be interesting to know whether the Guiana bird is similar to the 

 Venezuelan bird or not. 



b Immature males resemble adult females, but have th(^ posterior under parts tinged or 

 suffused with red or pink instead of orange or salmon color, the c'olor being also deejjer 

 and more extended.
