third toes, but reaching somewhat beyond penultimate subar- 
ticular tubercle on fourth; carpal tubercles prominent; subar- 
ticular tubercles on toes very strong; a very small metatarsal 
tubercle and a still smaller outer tubercle; third and fifth toes 
nearly equal; disks on toes pointed, much smaller than those 
on fingers; a slight skin fold on outer side of fifth toe, not 
continued on foot; no tubercle on heel; tibiotarsal articulation 
reaches considerably beyond tip of snout. 
Color in alcohol—Above blackish purple, nearly uniform; 
callous spots on head brown; tympanum brown; latter part of 
upper jaw whitish; an indistinct light spot under eye and in 
front of tympanum; arms and legs brownish, barred with darker . 
color; underside of femur and tibia spotted brown; a spot on 
underside of arm near insertion; throat and belly light; purplish 
spots low on sides.

Remarks.—The species is most closely related to Rana mearnsi 
Stejneger from Mindanao, from which it differs in having a 
longer, narrower, more-flattened head, a larger tympanum of 
different shape, and smaller toe disks. In the shape of the tymi- 
panum it is similar to Rana merrilli Taylor but lacks the folds 
below the anus and differs in measurements. The head is more 
pointed, and the head and body appear flatter. 
When I first examined this specimen I suspected that it was 
the very rare Polypedates hecticus. There is no distinct notch 
in front of the pad as is present in Philippine species, and dis- 
section of the fourth finger failed to reveal any intercalated 
bone.
