fingers
extending about one-fourth length of fourth finger. Heels overlap by
about one-third length of shank when hind limbs adpressed; tibiotarsal
articulation extends to anterior edge of eye; tarsal fold strong,
extending to heel; inner metatarsal tubercle large, high, and
elongate; outer metatarsal tubercle absent; subarticular tubercles
moderately large, round; supernumerary tubercles small, in single rows
on proximal segments of digits; toes moderately short; length of toes
from shortest to longest, 1-2-3-5-4, third and fifth toes about equal
in length; toes about two-thirds webbed; web extending to middle of
antepenultimate phalanx of fourth toe, to discs of first, second, and
fifth toes, and to base of penultimate phalanx of third toe; discs
rather small, about two-thirds size of those on fingers. Anal opening
at level of lower edge of thighs; anal sheath elongate, deeply creased
medially; transverse dermal fold above anus. Skin of dorsal surfaces
of head, body, and limbs faintly areolate; skin of chin, belly, and
ventral surfaces of thighs granular, that of ventral surfaces of
limbs, except thighs, areolate; thoracic fold absent. Tongue nearly
round, slightly longer than wide, shallowly notched behind and barely
free posteriorly. Vomerine teeth 4-4, situated on rounded vomerine
ridges between rather small ovoid inner nares; vocal slits present,
situated along posterior edge of each ramus.

Color (in alcohol) pale brown on dorsal surfaces of head, body, and
limbs; flanks and anterior surfaces of thighs creamy white with dark
brown reticulations; posterior surfaces of thighs tan with creamy
white spots; belly cream-color; anal stripe absent.

Color (in life) pale tan on dorsal surfaces; flanks and anterior
surfaces of thighs pale creamy yellow with purplish brown
reticulations; posterior surfaces of thighs tan with yellow spots;
ventral surfaces yellow; iris pale copper-color.

_Variation._--There is little variation in structure. The total number
of vomerine teeth varies from 6 to 14. In some individuals the
supratympanic fold covers the upper part of the tympanum, but at least
the lower part of the tympanum is always visible. The extent of the
webbing between the toes varies from three-fourths to two-thirds
complete. Usually the web extends to some point on the antepenultimate
phalanx of the fourth toe, but in some specimens the web extends to
the base of the penultimate phalanx.
