A REVIEW OF THE AMERICAN "GOLDEN WARBLERS." 

 ^- By ROBERT BIBGWAY. 



In a short paper* published in the Proceedings of the Biological 

 Society of Washiugton, vol. iii, i^p. 1-4, 1 briefly characterized a new 

 form of this group from the island of Cozumel, Yucatan, under the name 

 of Dendroica petechia rufivertex. The birds of this group being much con- 

 fused, it was found necessary, before the status of the Cozumel bird 

 could be determined, to carefully examine all the material available 

 (embraeiug considerably more than one hundred specimens from trop- 

 ical America, besides a very extensive series of D. (estiva from iSTorth 

 America) ; and as the results of this examination may be of interest, 

 a brief synopsis is herewith presented, together with a fuller diagnosis 

 of the Cozumel form, and also another new one from Lower California 

 and western Mexico : 



^- DeNDROICA petechia RUFIVERTEX. 



Dendroica peiecMa rufivertex, RiDGW. Proc. Biol. Soc. Washington, vol. iii, Feb. 26, 

 1885, p. 1. 



SuBSP. Char. — Similar to D. petechia ruficapilla (Gmel.), of St. 

 Thomas and other Lesser Antilles, but with shorter wings and tail, and 

 rather more intense coloration.

 January 28, 1885 ; J. E. Benedict and T. Lee) : Whole crown orange- 

 rufous, the feathers rich gamboge-yellow basally. Nape, back, scapu- 

 lars, and rump bright yellowish olive green ; upper tail coverts similar, 

 but edged with yellow. Wings blackish dusky, the feathers broadly 

 margined with olive-yellow (almost pure yellow on the coverts and ter- 

 tials). Outer webs of rectrices dusky, edged with olive-green ; inner 

 webs chiefly bright primrose-yellow. Lower parts, including whole side 

 of head, very rich tine gamboge-yellow, the jugulum, breast, sides, and 

 flanks broadly streaked with rich chestnut-rufous ; throat with much 

 smaller and indistinct streaks. Wing, 2.40 ; tail, 2.05 ; culmen, .55 ; 

 bill from nostril, .30 ; tarsus, .80 ; middle toe, .45.
