1 Dendroica petechia, Baied, Review, 199. (MotnciUa petechia, Linn. 1766.) 



A specimen from Port au Prince is smaller, measuring, wing, 2.50 ; tail, 2.10 ; bill, .31 ; 

 tarsus, .74. It is perhaps lighter gi-een above than Jamaican specimens. These features may 

 only be characteristic of the particular individual. 



- D. ruficripilla, Baird, Rev. 2lll. 



A single specimen from Porto Kico difters 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 Kico would be more like typical species 

 of this race as seen in the majority of those from St. Thomas and St. Bartholomew.

 which the type described in Review nearly ;igreed. Should Vieillot's species be really from Marti-
