 1 nation's Vireo. A species or variety 

 similar to the last, but differing much as 

 favoviridis does from ollvaceus, in having 

 the under parts almost entirely yellowish ; second quill about equal to the 

 tenth. Lower California and southward. An accredited species, but one 

 I have not tested, and cannot endorse. Cass., Proc. Acad. Phila. 1851, 

 150, 1852 ; pi. 1, f. 1 ; Bd., 339, pi. 78, f. 2 ; Rev. 357. . . iiuttonii. 

 BelVs Vireo. Olive-green, brighter on rump, ashier on head, but without 

 decided contrast ; head-markings almost exactly as in gilvus ; below, sul- 

 phury yellowish, only whitish on chin and middle of belly ; inner quills 

 edged with whitish; two whitish wing-bands, but one more conspicuous 



than the other. Hardly or not 5 

 long ; wing little over 2 ; tail under 

 2 ; spurious C]uill about | the second, 

 which equals or exceeds the seventh. 

 A ]ir('lty little species, like a mini- 

 ature gilvitf!, but readily distin- 

 guished from that species by its 

 small size, presence of decided wing-bars, more yellowish under parts, and 

 different wing-formula. Middle region, U. S., west to the Rocky Moun- 

 tains, east to Kansas (Ooues) and Illinois {Ridgwaij) ; an abundant species, 

 inhabiting copses and shrubbery in open country, with much the same 

 sprightly ways and loud song of 

 noveboracensis. Aud., vii, 333, pi.

 where. Size of bellii; wing and tail of equal lengths, little over 2 inches;
