yellow. The "female" diflFers in that the colors are less bright and 

 the belly less yellow. 



In both cases the habitat is "S. Domingue," "when specimens 

 have been sent to M. de Reamur by M. Chervain" Gmelin (Syst. nat. 

 1788, 1, pt. 2, p. 983) bases the name of [Motacilla] albicoUis on Le 

 Figuier de S. Domingue and that of [Motacilla] chloroleuca (p. 984) 

 on Le Petit Figiuer de S. Domingue, both of Brisson. 



As the Golden Warbler of Haiti is a well-marked race and as there 

 is no doubt that the birds of Brisson upon which Gmelin based his 

 names M. albicoUis and M. chloroleuca were a race of Dendroica 

 petechia, Gmelin's name albicoUis stands for the Haitian bird by reason 

 of priority of pagination with chloroleuca as a synonym. 



The only peculiar point in Brisson's descriptions is that he did not 

 have any fully plumaged birds, all of them possessing " soiled yellowish 

 white" throats and breasts. 



Dendroica petechia albicoUis is closest to D. p. petechia of Jamaica: 

 it differs from D. p. gundlachi of Cuba in being much lighter. The 

 bill is shorter and more slender than any of the Dendroica petechia 

 group, and this character alone serves to separate it from either 

 D. p. fiaviceps of the Bahamas or D. p. cruciana of Porto Rico. 



Subspecific characters. — Similar to Dendroica petechia petechia 

 (Linne) but much smaller (approaching D. p. gundlachi). Upper 

 parts, sides of head, and edging of primaries, secondaries, and wing- 

 coverts lighter, more golden, less olive-yellow; forehead and crown 

 more orange, less ochreous; traces present in juv. cf and ad. 9 ■ 

 Dusky portions of remiges and rectrices less dark, more brownish 

 (Ridgway, Bull. 50, U. S. N. M., 2, p. 515). Yellow of under parts 

 more intense, streaks fewer, averaging less heavy. Bill short, very 

 slender.

The Monte Cristi Golden Warl)ler was observed only near Monte 

 Cristi. The three birds taken were the only ones seen. It is not 

 recorded by either Bryant, Cory, Cherrie, or even Verrill. Ridgway 

 refers to an adult male from Haiti (Bull. 50, U. S. N. M., 2, p. 515), 

 but the collector's name is not given.
