fused; fingers long, moderately slender; discs moderately large;

_Variation._--In addition to the specimen described above three others
are known. One is a juvenile having a snout-vent length of 29.5 mm.,
and two are females having snout-vent lengths of 46.9 and 41.6 mm.
Variation in structure and coloration between the four specimens is
slight. In the females the tympani are partly visible and are about
one-third the diameter of the eye; the chest is mottled with brown;
