2. California Partridge; ** Valley-Quail ;" Lo- 

 phortyx calif ornicus (Shaw). 



Head plume erect or thrown forward; composed of 

 wedge-shaped feathers. Length ten and a half 

 inches. Upper parts olive-brown and gray; the 

 forehead pale buffy or whitish, finely lined with 

 black; top of head brown bordered with black; 

 throat black bordered with white; breast plum- 

 beous, changing below to bufFy or whitish, 

 where the feathers are bordered with dark brown, 

 giving the belly a scaled effect, and with a cen- 

 tral chestnut patch on belly; sides olive-brown, 

 wnth narrow streaks of white. The female is 

 similar, but lacks the black, white and chestnut, 

 making it much duller and more monotonous in 

 color. 



This variety of the valley-quail is found in the 

 coast valleys of the northwest coast of California 

 and northward. In central and southern Califor- 

 nia a slightly paler form, the valley-quail proper, is 

 found in the valleys and foothills both of the 

 coast and interior. 



3. Gambel's Partridge ; Lophortyx gambelii 

 (Gambel). 



Length a trifle less than the preceding, which it 

 resembles in general appearance. The top of 

 the head is bright rufous, the belly is black cen- 

 tered instead of chestnut, surrounded by a broad 

 patch of pale bufFy, and the sides are chestnut 

 with streaks of white instead of olive-brown, as 

 in the preceding. A desert form occurring in 

 California only on the Mojave and Colorado 

 Deserts.
