Hah. — Interior districts of California, including west slope of Sierra 

 Nevada; north to Sacramento, south to Walker's Basin, Tejon Mts., 

 and San Diego. 



The differences in coloration between this interior form and the coast 



race (true fasciafa) are very striking on comparison of si)ecimens, and 



may be briefly tabulated as follows: 



Var. FASCIATA. Above deep umber-brown, more grayish on side of 



head and neck; beneath deep cinnamon-butt", or light cinnamon, 



the throat and jugulum more or less distinctly streaked with dusky 



or grayish. Wing 2.20-2.G0, tail 3.20-3.70, culmen .40-.45, tarsus 



1.00-1.10. Hab.—Conat of California, south to Sta. Chira, north to 



or beyond Nicasio. 



Var. HENSHAWI. Above brownish gray or grayish brown, the sides 



of head and neck decidedly ashy; beneath pale cinnamon-buff, or 



pale vinaceous-buff', usually more or less suffused with pale ashy, 



the darker streaks on jugulum, etc., nearly or quite obsolete. Wing 



2.20-2.50, tail 3.20-3.70, culmen .40-.45,"^ tarsus .95-1.05. Rah.— 



Interior of California, including western slope of Sierra Nevada. 



As may be seen from the above measurements (taken from seven 



adult specimens of fasciata and eight of ItensJiaici), the dimensions of 



the two forms are essentially identical. The extreme development of 



the characters distinguishing C. henshawi is seen in specimens from 



Walker's Basin and the Tejon Mts., collected by Mr. H. W. Henshaw, 



tp whom this new form is dedicated. Specimens from Sacramento are 



darker, but still not enough so to make them referable to the coast form, 



to which all specimens from Stockton seem to belong. The darkest ex- 



amjiles of C. fasciata^ as restricted, come from the coast district north of 



San Francisco Bay (Nicasio, Marin Co., C. A. Allen).
