A NEW WARBLER FROM THE BAHAMA ISLANDS. 

 BY W. E. CLYDE TODD. 



From December, 1908, to May, 1909, Mr. W^illis W. Worth- 

 ington of Shelter Island Heights, New York, was engaged in 

 collecting natural history specimens in the Bahama Islands, 

 his material coming to me at the Carnegie Museum. He was 

 especially successful in securing specimens of the rarer and 

 more interesting Bahaman birds, among them a remarkable 

 new species of warbler which, in advance of a formal report on 

 the collection as a whole, I propose to call: 



Dendroica flavescens sp. nov. 



YELLOW-BREASTED WARFiLER. 



Type, No. 19,887, Collection of W. W. Wortliington, adult male; 

 Spencer's Point, Abaco, Bahama Islands, May 7, 1909; W. W. Worth- 

 in gton. 



Specific Characters. — Similar to Dendroica dominica Linnpens, but bill 

 longer and slightly decurved, and entire lower parts (except under tail- 

 coverts) yellow. 



Description. — Adult male: above plain slate-gray (duller than in D. 

 dominica) ; wings and tail dusky l)lack with slate-gray edgings, the middle 

 and greater coverts tipped with white, forming two conspicuous bands 

 across wing; two outer rectrices with inner webs extensively white, and 

 a more or less distinct white spot on third rectrix also; auricular and post- 

 orl)ital regions, rictal streak, and lores black ; forehead and sides of crown 

 sometimes (always in full plumage?) black; suborbital spot and super- 

 ciliary stripe white, the latter becoming pale yellow anteriorly ; a small 

 patch on sides of neck, behind the auriculars, white; below pale yellow, 

 brightest on the throat and breast, fading to nearly white on the lower 

 abdomen and under tail-coverts, tlie sides streaked broadly with black, 

 confluent with the black auricular patch ; under tail-coverts obscurely 

 streaked with dusky; under wing-coverts white; bend of wing tinged 

 with yellow; bill black; feet dusky (in skin). Adult female similar, a 

 little duller, the back slightly washed with olivaceous. Innnalure female 

 (first nuptial plumage) similar, but still duller in general coloration.
