w on proximal segment of each
digit; toes about two-thirds webbed; webbing extends from middle of
penultimate phalanx of first toe to base of penultimate phalanx of
second, from middle of penultimate of second to middle of
antepenultimate of third, from middle of penultimate of third to middle
of antepenultimate of fourth to middle of penultimate phalanx of fifth
toe.
Anal opening directed posteriorly at level of mid-thigh; anal sheath
short. Skin granular on chin, belly, and posteroventral surfaces of
thighs, smooth elsewhere. Tongue broadly cordiform, notched posteriorly,
barely free behind. Prevomerine teeth 4-4, situated on posteromedially
inclined elevations between small ovoid choanae. Vocal slits absent.
Color (in preservative): dull grayish brown above with small,
irregularly-shaped black spots on head, back, and limbs; flanks gray
mottled with creamy tan; anterior and posterior surfaces of thighs tan;
belly dull creamy tan; throat marked with gray blotches; anal region and
posterodorsal surfaces of thighs marked with small white spots.
Color (in life): dorsum pale green with black spots and reticulations;
flanks mottled dark brown and creamy white; outer edges of feet silvery
white with brown spots; anterior and posterior surfaces of thighs dull
brown; webbing and first three toes dull yellowish tan; belly creamy
gray; throat silvery white, mottled with gray; iris dull bronze-color
with black reticulations; palpebral membrane clear.
_Variation._--The snout-vent length in seven adult males is 47.2-50.0
mm., and in five females, 45.1-52.5 mm. In neither sex do the average
proportions differ noticeably from those of the holotype, except that
the tympanum is relatively larger in females. The ratio of the diameter
of the tympanum to that of the eye is 0.363-0.468 (mean 0.438) in males
and 0.500-0.545 (mean 0.516) in females. The average number of
prevomerine teeth in males is 7.9, in females 8.4.
In life dorsal coloration varied from pale green to olive-green with
darker green or black flecks or reticulations, or pinkish tan to brown
with dark brown flecks or reticulations. Some preserved specimens have
relatively few dark flecks, whereas in most specimens the dorsum is
heavily marked. All specimens have some white markings above the anus
and on the posterodorsal surfaces of the thighs, but in some individuals
the white flecks are expanded and interconnected forming an irregular
white line.
