Interior valle^^s and foothills and southern coast district of Califor- 

 nia, from eastern slope of the Coast Range in Napa and Lake counties

« There is considerable variation in the color of the under parts, according to 

 locality, and some in different specimens from the same place; but considering the 

 very great geographic range of the present form compared with that of any other of 

 the species, the coloration is remarkably uniform. Examples from Butte County are 

 quite as pale and gray beneath as those from Walkers Basin (the type locality), but 

 occasional specimens from the southern coast district are nearly as deeply colored 

 beneath as true C.fasciata.
