D. ruficapilla, Baird, Rev. 201.

A single specimen from Porto Rico differs in some respects from the average of a series from the other islands named. The chief differences are, less thickly streaked throat, and distinct shaft-streaks of dark chestnut on the back. However, one or two specimens of true ruficapilla from St. Thomas have the upper part of the throat streaked, and one of them has the streaks on the back. In all probability other specimens from Porto Rico would be more like typical species of this race as seen in the majority of those from St. Thomas and St. Bartholomew.
