the acaciao. They depart rather earher than most of the North: 

 American migrants, being mucli reduced in numbers by March 15 and 

 practically all have left by April 1. A straggler was killed at Sosiia^ 

 April 10, the bird was a female in worn plumage and showed no signs, 

 of sexual activity. 



82. Dendroica caerulescens caerulescens (Gmehn). 



Three specimens, both sexes, Choco, Los Toritos. 



The Black-throated Blue Warbler is a common migrant on the 

 north coast, but does not occur to any extent during the winter. The 

 first individuals were seen on March 11, and by the 25th the species 

 had reached its greatest abundance. None were seen after April 1. 



83. Dendroica tigrina (Gmelin). 



Five specimens, both sexes, Monte Cristi, Jaibon, Sosua, Arroyo 

 Savanna. 



Common winter resident. 



82. Dendroica petechia albicollis (Gmelin). 



Three specimens, Monte Cristi, 



Brisson in his Ornithologie describes and figures (3, p. 494, pi. 26, 

 fig. 5) Le Figuier de S. Domingue, Ficedula dominicensis . His 

 description is most certainly that of Dendroica petechia, probably a 

 young male, as the throat and breast are described as being a soiled 

 yellowish white. The chances that any other Dendroica except 

 possibly D. aestiva could be included in Brisson's account may be 

 rejected, as the inner webs of the lateral retrices are mentioned as 

 being extensively yellow. His measurements agree with those of 

 D. p. petechia quite well, moreover there is no certain record for D. 

 aestiva in the West Indies. His female is similar to the male except 

 that there is a little ashy on the upper part of the neck. 



In the same work (3, p. 49(3, pi. 26, fig. 2) he describes Le petit 

 Figuier (le S. Domingue, Ficedula dominicensis minor. This time his 

 account refers to a female of Z>. petechia as reference to the streaking 

 on the breast is omitted; the under parts are again a dirty yellowish 

 white, but the inner webs of the lateral retrices are more extensively
