NOTICE OF A SUPPOSED NEW VIREO FROM 



OREGON. 



BY A. W. ANTHONY. 



A recent comparison of specimens of Vireo huttoni from north- 

 western Oregon with a series from southern California, in my col- 

 lection, leads me to believe that there are two well-defined races 

 represented. 



The series of northern birds is, however, not large enough to 

 enable me to fully establish the standing of that form — the status of 

 which I propose to determine as soon as I can obtain sufficient 

 material. 



Specimens from northwestern Oregon (Washington County) and 

 the region of Salem exhibit a uniformly rich suffusion of olive and 

 yellowish tints, much brighter than in any California examples which 

 I have examined, together with darker upper parts, and much more 

 buffy breasts. 



Selecting as typical examples of the two forms a specimen from 

 my collection taken at Beaverton, Washington County, Oregon, 

 March 20, and a specimen collected March 19, at Santa Ysabel, 

 San Diego County, California, from the collection of F. Stephens, 

 the differences may be summed up as follows; 



California (huttoni). 



Wing bars white. Primaries, 

 secondaries and rectrices edged 

 with pale olive-green, brightest 

 on tail. Above, olive-gray; pale 

 olive on rump. 





Under parts olivaceous-white; 

 sides more olivaceous, purest be- 

 hind; very slight buffy tinge on 

 breast. 



Loral region and narrow ring 

 around eye, dull yellowish-white. 



Oregon (obscurus). 



Wing bars yellowish - white. 

 Primaries, secondaries and rect- 

 rices edged with rich olive-green, 

 brighter on tail. Above, darker; 

 olive tints darker and much 

 brighter. 



Under parts buffy-white, purest 

 behind; sides and flanks oliva- 

 ceous-buffy. 



Loral region dusky-white, a 

 narrow ring of yellowish - white 

 surrounding the eye, and sharply 

 contrasting with surrounding 

 parts.
