Variation.—Specimens from Palawan agree very well in most 
characteristics; some are darker, almost coal-black with prac- 
tically no yellow or white dots above, while others are lighter, 
gray-brown, with black-brown bars on legs, and very indistinct 
markings on back; males appear to have more dusky markings 
on throat than females. Mindanao specimens have the ground 
color of throat dark, with roundish yellow spots. 
Tadpoles.—A good series of tadpoles was taken, from speci- 
mens with no legs to those that had completed their transforma- 
tion. Description of specimen: Total length, 23 millimeters; 
body, 9; tail, 14; hind legs 10. Eyes very distinct, lateral, 
distance between them more than twice their distance to end 
of snout; nostrils close together, nearer tip of snout than eye; 
spiracle on left side. Owing to the state of preservation I am 
unable to determine the characters of the teeth and labial den- 
ticulation. Color blackish, rather lighter below. 
Remarks.—This species was first discovered in June, 1913, 
in the low mountains along the boundary of Davao and Agusan 
Provinces, Mindanao, between Agusan and Simulao Rivers. Sev- 
eral adults were taken in a small pool of water in a hole in a 
tree trunk, only about one-third meter above ground. In May, 
1918, several specimens were taken in the extreme northern part 
of Palawan. Young and adult specimens were found under rocks 
along nearly dry stream beds in low mountains; later tadpoles 
were found in a water-filled cavity, nearly a meter from the 
ground, close to the base of a large tree, not far from the same 
stream. A good series of tadpoles was taken, as well as a few 
recently transformed young. In the same pool of water another 
large tadpole was taken, but I am unable to identify it. 
The adults are very agile and, owing to their small size and 
dark color, are seen only with difficulty. Certainly common in 
northern Palawan, but probably rare in Mindanao. Known from 
only these two localities in the Philippines.
