Omit measurements from diagnosis, to which add the following :

 sides of pileum, scapulars, etc.) and relieved by broad irregularly sagittate or 

 diamond-shaped spots on scapulars ; chin and sides of head blackish ; chest 

 (next to white throat-patch) with black predominating, the sides and flanks 

 more heavily barred with dusky ; ochraceous of quills deeper, and more 

 restricted ; wing 5.50-6.15 (5.78), tail 3.40-3.80 (3.67). Hab. Western United 

 States in general, excepting more southern plains, east of Eocky Mountains. 



418. P. nuttalli (Auo.). Poor-will.

Note. It is not improbable that the Californian birds of this species, 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 Califorman 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.
