Seven adult males agree closely in the characters given above. 

 There is some variation, however, which it may be well to note. Two 

 specimens have the whole throat distinctly streaked, while two have 

 scarcely a trace of these streaks, the others being intermediate. All 

 have the whole crown bright orange-rufous, except one, in which only 

 the anterior part of the crown is of this color. The color of the crown- 

 patch is not so dark as in 1). riifopileata from Old Providence (see 

 these "Proceedings," vol. vii, p. 173), neither is it abruptly outlined as 

 in that species and D. capitaUs Lawr., from Barbadoes. The relation- 

 ships of this form are decidely with D. petechia rujicapilla and D. petechia 

 melanoptera, of the Lesser Antilles, difference of proportion being the 

 chief distinction, the former being larger, the latter smaller, than the 

 Cozumel race. 



It is with much reluctance that I here present an additional race of 

 this perplexing group ; and it is only after the most careful considera- 

 tion of the subject that I have concluded to do so. Anomalies in the 

 distribution of the several local forms indicate the importance of dis- 

 tinguishing them by name, in order that the subject may be more con- 

 veniently handled. 



The group is a most interesting and at the same time very perplexing 

 one. In most forms the characters are easily recognizable, the differentia- 

 tion having reached a point which maybe regarded as specific. In other 

 cases the differentiation, while equally constant, is comparatively slight, 

 and perhaps best considered as of subspecific value only. Proceeding 

 on this basis, the group of " Golden Warblers," as at present known, 

 may be arranged as follows, the arrangement here presented being 

 based on more than one hundred adult males : 



A. Tarsus usually less, and never more, than .75 of an Inch ; head of adult male yel- 



low, the crown more olivaceous, and never with a distinct suffusion 

 or patch of rufous. 



1. D. sestiva (Gm.). — Hah. Continental ; whole of North America, south in winter 



through Central America, to Colombia, Venezuela, Guiana, Trini- 

 dad, and Tobago. 



B. Tarsus usually more, and never less, than .75 of an inch. 



a. Head of adult male yellow, the crown with a distinct suffusion of orange- 

 rufous.
