The western variety of the Fox Sparrow. There 

 is one record of the eastern variety from San 

 Diego. Length about seven inches. Above 

 plain dark brown or grayish brown, unstreaked; 

 wings and tail rufous in tone ; below white, 

 heavily marked with triangular spots of brown 

 on the breast, and streaks of the same on the 

 sides. Common winter resident of the valleys 

 of central CaHfornia, becoming rare to the 

 southward where it occurs as far as San Diego. 

 Another variety of the fox sparrow occurs in the 

 mountains of southern California, recently de- 

 scribed as Stephen's Sparrow, Passer ella iliaca 

 stephensiy Anthony. The Thick-billed Sparrow 

 (^Passer ella iliaca megarhyncha (Baird) is the 

 variety of the fox sparrow breeding in the 

 Sierra Nevada Mountains. It is colored olive 

 slaty above, and the bill is much larger and 

 thicker than in Townsend's sparrow. Other- 

 wise they are practically alike. The Slate Colored 

 Sparrow (^Passer ella iliaca schist ace a (Baird) is 

 another variety of the fox sparrow, occurring in 

 the Rocky Mountains and straying occasionally 

 into the Sierra Nevada Mountains during migra- 

 tions. It is similar to the preceding, but smaller, 

 and with more slender bill
