Variation.—Five other specimens were taken, all more or less 
resembling the type in markings and color. One specimen (No. 
759) had a large red blotch on the groin. When preserved the 
markings of most of the specimens changed. The gray area on 
the back disappeared, and the entire body assumed a brownish 
color, with two longitudinal dark markings running parallel on 
the back from occiput to middle of back and two short longitud- 
inal marks on sides ending near the groin. The tubercle on the 
tongue is more or less distinct in all the specimens. 
One of the specimens (No. 760, length 23 millimeters) is full 
of eggs. These are yellow and are very large, measuring from 
3 to 3.5 millimeters in diameter. 
The males have vocal sacs; the opening is situated near the 
angle of the jaws. 
Remarks.—The specimens were taken in the small brook, just 
behind the town of Balbalan, which furnishes water to the town. 
They were seated on the leaves of a plant growing over the 
running water. Instead of jumping when I approached, they 
merely crouched close to the edges of the leaves in which posi-
