Plate XIII. (xf). i, 2. 



Males. 3, 4. Young. 5. Fe- 

 male. 



Bufo calijornicus (Camp). 



Range: Coastal region of 

 southern California (Ventura 

 Co., Los Angeles Co., San 

 Diego Co.) into Lower Cali- 

 fornia. Across divide into San 

 Bernardino County. The 

 early records were confined 

 almost entirely to the foot- 

 hills of the western slope. 



Habitat: "Moderately com- 

 mon in inland valleys and 

 foothills/'— (L. M. Klauber, 

 1928, p. 2). "In San Diego 

 County the range seems 

 largely restricted to the sandy 

 washes of the rivers in the 

 Upper Sonoran Zone."- 

 (Klauber, 1931, p. 141). 



Size: Adults, 1 5/8-2 3/4 

 inches (42-68 mm.). 



General appearance: This is 

 like a small Great Plains 

 Toad {Bufo cognatus), but is 

 more uniform in color on the 

 back, lacking the conspicu- 

 ous dark spots and light 

 streaks and vertebral streak 

 of that form. The limbs are 

 barred or spotted with black. 

 This little toad is very short 

 and thick in body, very short 

 in head, and the arms and legs 

 appear very stolid. The foot 

 is a little longer than in B. 

 cognatus. The eyelids and 

 parotoids are tuberculate. 

 Several of the larger warts 

 have spiny tips, in some
