ISrOKTH AMERICAK FAUNA. 



[No. 38. 



is a small spot of ochraceous-buff and a faint wash of the same color 

 on the throat. Similar chromatic abnormalities crop out in several 

 specimens from the type locality, and one specimen (No. 204998, 

 U. S. Nat. Mus.) has as a dental abnormahty a supernumerary left 

 upper premolar. 



Intergradation of this form with orarius is clearly indicated in 

 specimens from the west slope of the Cascade Mountains in Oregon 

 and Washington. Specimens from Vida, McKenzie Bridge, and 

 Three Sisters, in Oregon, approach orarius in color and in cranial 

 characters, though distinctly referable to schefferi. Specimens from 

 Mount Vernon, Wash., are slightly darker in color than specimens 

 from Walla Walla, but the skulls are almost identical in essential 

 characters with the type series. Specimens from Skykomish, Wash., 

 are nearly as dark as typical orarius, but are referred to schefferi 

 because of cranial characters which, although approaching orarius, 

 are much nearer schefferi.
