Omit measurements from diagnosis, to which add the following: 
a’, Larger and darker, with prevailing color above grayish brown (more grayish 
on 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 Rocky Mountains...... 418. P, nuttalli (Aup.). Poor-will. 
a Smaller and paler, with prevailing color above pale brownish gray, inclining 
in places to pale hoary or silvery whitish, relieved by smaller or narrower 
black markings; chin and sides of head finely mottled grayish brown; 
chest with little, if any, of uniform black; sides and flanks more nar- 
rowly barred (the latter sometimes immaculate); ochraceous of quills 
piler and more extended; wing 5.40-5.75 (6.44), tail 3.50-3.60 (3.52).

This form, which is very uniform in its characters throughout a very extensive territory, and therefore 
entitled to recognition, entirely replaces both M. formicivorus and M. f. bairdi in the region indicated above. 
The measurements and habitat of M. f. bairdi given on page 291 include the present form and require correction 
accordingly.

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 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.
