Coloration. — Above hair brown sliglitly browner on top of the liead ; 

 upper tail-coverts and tail Isabella color. Ground color of underparts 

 and sides of head white, except a scarcely discernible tinge of cream buff 

 across the breast ; sides and flanks faintly washed with drab gray. 

 Spots on breast sepia, small in size and few in number; a series extends 

 on each side up to the ramus of the lower mandible forming two malar 

 stripes which enclose an immaculate throat patch. Outer surface of 

 closed wing isabella color. 



Type. — (J ad., No. 14096, Coll. California Academy of Sciences;

 California, May 9, 1S98. 



Range. — Breeds in the cloudy coast belt of California, from southern 

 Monterey County northward, locally at least, to Sonoma County. A 

 typical specimen (No. 967, Coll. J. G.) taken at Pasadena, California, 

 April 25, 1896, and another (No. 10662, Coll. C. A. S.) obtained on Santa

 points along the migration route of this race. 



Measurements. — The following table shows the average length in 

 millimeters of the wings and tails of all available summer adults from 

 the localities named.

 in decidedly smaller size, and from aonalaschkce, verecii/ida, slevini 

 and nanus in larger size and paler coloration. The type of audu-
