1 Deadroica petechia, Baird, Review, 199. (Motac ilia 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 green above than Jamaican specimens. These features may 

 only be characteristic of the particular individual. 



2 D. rufimpilla, 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 ruficapilln 

 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.

® D. rufiguhi, Baird, Rev. p. 204. The habitat as Martinique, W. L, was there queried, but 

 without any reason for so doing other than that this was the locality of Vieillot's species, with 

 which the type described in Review nearl}' agreed. Should Vieillot's species be really from Marti- 

 nique, in all probability the present bird will be found to be different, and therefore not entitled to 

 the name here given. Provided such is the case, the name ^' rufccps," Cabanis, cannot with
