Variation—Twenty-two specimens of this species were taken 
breeding in rain pools in the town of Balbalan, from April 28 to 
April 30, 1920. Most of the specimens are identical in most

the condition of the skin. The females are distended with eggs, 
and when alive they were almost triangular in shape. Most of 
the specimens are colored like the type. One female (No. 838A) 
is light lavender-brown above with purplish black markings on 
the back, arranged roughly in the shape of a human being with 
limbs outstreched; there are two well-defined dark spots above 
the anus, and the limbs are distinctly spotted; the lores and the
