HYPOTHETICALLIST [605] 



specimen, and in view of the indefinite labeling of a number of the speci- 

 mens taken on this expedition, we are inclined to doubt the correctness 

 of the locality record. We have hunted assiduously in southern Oregon 

 for this small bird without success. It should therefore appear in this 

 list as a hypothetical record until specimens are taken. This is not 

 entirely impossible as the bird ranges north in California well toward the 

 Oregon line. 



Cassin's Kingbird: 



Tyrannus vociferans Swainson 



BENDIRE (1895) recorded this species from Beaverton, Oregon, on the 

 strength of statements by A. W. Anthony. Prill (192.2^) recorded it from 

 the Warner Valley. There is no question but that these records refer to 

 the Arkansas Kingbird, which is an abundant species in the Warner 

 Valley and a regular straggler in western Oregon. 



Black Phoebe: 



Sayornis nigricans nigricans (Swainson) 



THIS is another one of the birds recorded from Oregon from the Umpqua 

 Valley by Newberry (1857). Johnson (1880) recorded a bird from Salem 

 in July 1879. We have not been able to trace satisfactorily these records 

 of this southern bird and are therefore placing it in the hypothetical list. 

 It may possibly be taken in the State at some future date. 



Yellow-billed Magpie: 



Pica nuttalli (Audubon) 



STONE (1892.) referred to a record of this bird from the Columbia River 

 from the Townsend collection. There is no other indication that the 

 species has ever appeared in Oregon. We are therefore placing it in the 

 hypothetical list. 



Nicasio Wren: 



Thryomanes bewicki marinensis Grinnell 



THIS SUBSPECIES is recorded in the last A. O. U. Check-List as occurring 

 from the southwestern coast of Oregon to Marin County, California. 

 We do not know the basis for this statement and have never obtained 

 specimens within the State limits definitely referable to this form.
