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 
zstiva ; the top and side of the head lack the bright yellow. The 
tibie 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 estiva 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 xstiva; the Ist 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. Domingan and the Cuban birds are the same; and even if 
identical, the name albicollis 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 albicollis.
