toward the grayish type. It is evident that in this part of the state 

 an arbitrary hne must be drawn between the ranges of the two 

 subspecies, and from the material available at the present writing, 

 it seems as though this division may be indicated about through 

 the middle of Siskiyou County. The single specimen at hand 

 from Yreka is of the calif ornieus type, and there are others of simi- 

 lar character from southcentral Oregon.

Distinguishing Characters. — As compared with P. minimus 

 minimus, of clear gray and white tones of color, rather than of the 

 brownish hue of that subspecies. Typical californicus is often 

 almost pure white beneath, noticeably so in the juvenal plumage. 

 Sides and flanks slightly or not at all tinged with vinaceous.
