remarked, however, these differences in coloration may be less appa- 

 rent with more perfect specimens. 



The upper parts are much darker and more olivaceous than in 

 sestiva ; the top and side of the head lack the bright yellow. The 

 tibiae are grayish-olive, not bright yellow ; the yellow of the wing 

 coverts is wanting, and the yellow edging of the quills internally 

 much less. In sesliva the yellow of the tail is more extended — the 

 outer feather being entirely of this color, excepting a streak in the 

 end of the outer web ; and even in the fifth tail feather the entire 

 inner web is yellow, except at the extreme tip. The wing is much 

 more pointed in sediva ; the 1st quill being generally longest, and 

 considerably exceeding the 4th, instead of being less. 



The determination of the specific name of this species has been a 

 matter of considerable perplexity. I am by no means satisfied that 

 the St. Doraingan and the Cuban birds are the same ; and even if 

 identical, the name alhicollis is a misnomer, liable to cause a very 

 erroneous impression, as the throat is golden-yellow, except in the 

 very young bird, when alone it is dirty whitish. I have, therefore, 

 thought best to impose a new name, borrowing it from the eminent 

 naturalist who has given to us a knowledge of the Ornithology of 

 Cuba scarcely less perfect than that of the eastern United States. 



The name of chloroleuca, Gmelin, which may refer to the same 

 species, unless there be two with rufous crown in St. Domingo, is 

 equally objectionable with albicoUis.
