Note. — It is not improbable that the Californian birds of this speoies, at least those from the more humid 

 and wooded northern coast districts, will have to be separated as a local race, characterized by very dark colors, 

 with heavier markings. At least the two Californian examples in the National Museum collection (one from 

 Nicasio, the other from Calaveras County) are altogether darker than any from elsewhere. Should additional 

 material show the observed differences to be constant, I would propose for this dark northwestern race the 

 name P. nuttalli californicus.
