Ozs. Another species or variety of this long-billed, 9-primaried group, V. jla- 
voviridis (Cass., Proc. Acad. Phila. 1851, 152: Bp., 332 and Rev. 336), 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 under parts are yellow, brighter perhaps, 
at least on the axillars and crissum, than olivaceuws ever becomes, even in the fall. 
Lrotherly-love Vireo. Above dull olive-green, brightening on the rump,
