Range: Southern portions 

 of Utah and Nevada south 

 far into Mexico, and east to 

 Oklahoma and the eastern 

 timber belt of Texas. 



Habitat: We found this 

 toad breeding in rain pools in 

 open fields near streams, in 

 pools in creek valleys, in ir- 

 rigation tanks or cattle tanks. 

 It is a desert form that may 

 at times be seen feeding at 

 night under the street lights 

 of desert towns. 



Size: Adults, 2 1/12-3 5/8 

 inches. (Males, 52-78 mm. 

 Females, 54-91 mm.). 



General appearance: This 

 broad, "squatty" toad of 

 medium size is pinkish drab 

 in color, marked with dull 

 citrine spots. The fingers and 

 toes are light in color. The 

 under parts are light. The 

 back is covered with light 

 tipped tubercles. In the male, 

 the tip of the chin is white, 

 then the folded part of the 

 throat is pinkish buff with 

 ecru-olive in the center. This 

 area is followed by a circular 

 pectoral area of purplish lilac. 



Structure: Parotoid, elon- 

 gate, sometimes smooth; no 

 sharp-edged ridge from eye to
