Variation . — The specimen here described was collected in Bu- 
nawan, Agusan, Mindanao, in 1912. In 1917 I discovered the 
species in Basilan, at a point on the west coast directly opposite 
the small island of Great Govenen. Most of the specimens taken 
were darker than the Agusan specimen, their bellies were orange, 
with numerous rather large yellowish white spots on sides of 
the belly and chin. The number and prominence of the dorsal 
yellow spots vary, some specimens having very few spots on 
head and legs; the spiny granules on heels and belov/ anus are 
yellowish. In the type the third toe is distinctly longer than 
the fifth ; in Basilan specimens they are equal or nearly so, and 
the distance from nostril to tip of snout is less. 
Tadpoles . — A few tadpoles of this species were taken with 
the adults; also an immature specimen, which had just completed 
its transformation. 
Description of tadpole. — Length, v/ith hind legs, 6.5 milli- 
meters; body nearly one and a half times as long as broad, but 
much shorter than tail; depth of tail in tail length more than 
four times; nostrils much nearer end of snout than eye; eyes 
on upper surface of body ; distance between them equal to their 
distance from nostrils; a deep trough-shaped groove between 
and behind eyes, continued forward as a narrow linear groove 
to end of snout; in front of eyes, and somewhat below, are two 
large rounded pouches; mouth narrow; inside the mouth, and 
almost concealed, are two series of teeth which are a deep dark 
brown; the upper is curved with only a very small angle; 
the lower series rather V-shaped; these teeth plates seemed 
to be wanting in older specimens of the tadpoles. The speci- 
mens are in a rather indifferent state of preservation, and 
I am unable to determine the character of the upper and lower 
labial teeth.
