ASIO MAGELLANICUS PACIFICUS (Cassin). 



Bubo virginianus \ariety pacificufi Cassix, Illustr. Birds Calif., Texas, etc., 1854, 

 p. 178. 



Chars, suhsp. — Similar to A.'iio magellanicus pallesce?is, but dai'ker 

 throughout; feet much more heavily mottled with dusky: faee with 

 usually more admixture of rufous. 



Type locality. — Western North America (southern California"). 



Geographical distrihution. — California, except the southeastern part 

 and the northern and central coast districts; extending northward to 

 Fort Klamath, Oregon, eastward to the San Francisco Mountains, 

 Arizona. 



Measurements (6 males). — Wing, 313-353 (average 336.5) mm.; tail, 

 190-218 (average, 201.5) mm.; exposed culmen, 31—38 (average, 3(5) 

 nmi.; culmen without cere, 25-27 (av^erage, 26) mm. (4. females.) — 

 Wing, 350-370 (average, 360.7) mm.; tail, 213-228 (average, 219.3) 

 nun.; exposed culmen, 31-38 (average 36.8) mm.; culmen without 

 cere, 27-28 (average, 27.5) mm. 



A specimen from Fort Klamath, Oregon, doubtless referable here, 

 is very ochraceous, and suggests the existence of another phase in this 

 race. A single bird from San Bernardino, California, is quite as small as 

 cl((cJiixtii><, but probably is abnormally so, as specimens from farther 

 south are much larger. None oi pacific as irom Lower California ha\e 

 been examined, though the present subspecies undoubtedly occupies 

 at least the extreme northern portion. The reference of the birds from 

 the region of the Grand Can3'on of the Colorado, Arizona, to jjacificii.s 

 is not wholly satisfactory, though the only specimens we have seen — 

 one from the San Francisco ]Mountains and another from the Coconino 

 Plateau. Arizona — appear to be nearest this form. The tirst-mentioned 

 example is decidedly larger than any of our specimens of pacificas, 

 besides being rather dark, and, after all, this and the one from the 

 Coconino Plateau may l)e nothing more than dark-phase internnHliates 

 l)etween 2^allesce)is and occidentalis. 



Specimens from the following localities have })een seen:

 nardino; Fort Crook; Kern Lakes; Red Blutf. 



Arizona. — San Francisco Mountain; Coconino Platcnuudl rand Canyon 

 of the Colorado.
