Two and perhaps three geographic forms are strongly indicated by the series of speci- 

 mens examined; true P.r. mexicanus of Mexico in general and the adjacent parts of the 

 southwestern United States, a smaller form with larger and relatively broader bill and 

 less orange hue of red from Yucatan and Guatemala, and a still smaller form, with red 

 of under parts paler, from southern Honduras (Segovia River); but the material at 

 hand is not sufficient for their satisfactory definition.
