* 1 Dendroica petechia^ Baird, Review, 199. (MofaciJIa jiefcchia, Lixx. 1766.) 



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

 tarsus, .7-1. It is iwrhaps lighter green above than Jamaicau specimens. These features may 

 only lie characteristic of the particular individual. 



2 D. ruficapillay Baiud, Rev. 201. 



A single specimen from Porto Rico ditl'ers in some r»*spects from the average of a series from 

 the other islands named. The chief differemes are, less thickly streaked throat, and distinct 

 shaft-streaks of dark chestnut on the Kick. However, one or two s|>ecin>ens of true rnficapilla 

 from St. Thomas have the upjH'r part of the throat streaked, and one of them has the streaks on 

 the back. In all probability other specimens from Porto Rico would Ik- more like typical species 

 of this race as seen in th- majority of those from St. Thonias aiul St. Bartholomew.
