Besides the gradual increase in size toward the northward, indicated by the above 

 measurements, there is a variation in color of under parts in the opposite direction, 

 specimens from north of San Francisco Bay (in Marin, Sonoma, and Mendocino coun- 

 ties, CaUfomia) being often pale drab-grayish or bufty grayish below, thus showing a 

 tendency toward D. v. harrisi, as should be expected from the fact that the range of 

 the latter begins in the next county northward.
