Obs. Another species or varietjr of this long-billed, 9-primaried group, V. fla- 

 vovirkUs (Cass., Proc. Acad. Phila. 1851, 153: Bd., 332 and Rev. 330), occurs 

 in Mexico and may be expected over our border, though no specimens appear to 

 have been taken within our limits ; it has been admitted into late systematic works. 

 It closely resembles olivaceus, but the mider parts are j'ellow, brighter perhaps, 

 at least on the axillars and crissum, than olivaceus ever becomes, even in the fall. 



i Brotlterly-love Vireo. Above dull olive-green, brightening on the rump, 



fading insensibly into ashy on the crown, 

 which is not bordered with blackish ; a dull 

 white superciliary line ; below, palest possible 

 yellowish, whitening on throat and belly, 

 slightly olive-shaded on sides ; sometimes a 

 slight creamjr or buffy shade throughout the 

 imder parts ; no obvious wing-bars ; no spuri- 

 ous quill. About 5 long ; wing 2| ; tail 2J ; bill hardly or al)out J ; tarsus §. 

 Eastern North America; a small, plainly colored species, almost indistin- 

 guishable from gilvus except by absence 

 of spurious quill; not very common.

 v^"* Warbling Vireo. Colors precisely as 

 \w»> in the last species ; spurious quill present, 

 * \-^ as long as the second primary. fig. u,i. waiuiing viico. 



Eastern North America, an abundant little bird and an exquisite songster. 

 Its voice is not strong, and many birds excel it in brilliancy of execution ;
