2. Vireo Bartramii. (Swainson.) Bartram's Greenlet. 



Genus, Vireo. Vieillot. 



Ch. Sp. Vireo Bartramii, colore Vireonis olivacei sed clarion, statura rninori, alis brevioribus magisque rotun- 



datis ; remige prima sextam mquanti : remigibus tertiis et quartis longissimis. 

 Sp. Ch. Bartram's Fly-catcher, plumage of V. olivaceus, but brighter ; stature smaller; wings shorter, more 



rounded ; the first and sixth quills nearly equal, the third and fourth longest. 



To this species, which does not appear to have been distinctly defined, or 

 recorded as a native of the United States, we have affixed the name of one 

 whose love of science, no less than his devotion to the study of Nature, will 

 long render his memory dear to the admirers of Wilson. There are four 

 described species which come so near to this, that we shall briefly state in what 

 they appear to differ. 



1. The Muscicapa melodia of Wilson, or Vireo gilva of Bonaparte, if correctly described, 

 must be distinct : it has the head " only inclining a little to ash," and has no black 

 line bordering the crown. Prince Charles Bonaparte expressly says, the bill is " short," 

 in opposition to that of Olivaceus, which he terms " long." The colours are " much 

 less vivid and striking than those of Olivaceus :" in ours they are the same, or rather 

 more bright. Again, the same observing ornithologist remarks, that the longer and more 

 robust bill of Olivaceus distinguishes it from Gilvus: but the bill of our species is of 

 the same size and length as that of the former.
