The group of Golden Warblers has always presented difficulties 

 to the ornithologist, and my studies have been hampered by the 

 impossibility of procuring a sufficient series of adult birds for com- 

 parison. Young birds and specimens in winter ])lumage are of 

 little assistance to the student, as they are all so much alike. The 

 older literature is very much confused — as, for instance, when 

 Brisson describes a Golden Warbler from S. Domingo, an island 

 where, as far as we know, none has ever been found ; and again, 

 when he describes a " Figuier de Martinique," which is most cer- 

 tainly not the species met with in that island. Although I have 

 had the advantage of comparing the specimens in the Museum with 

 those in the collection of Messrs. Godman and Salvin, n much larger 

 series of adult specimens is necessary for the correct discrimination 

 of all the insular forms of Golden Warblers, and therefore some of 

 my conclusions may have to be modified hereafter.
