tip of snout 70.6 per cent of length
of eye; snout in lateral profile angular, sloping abruptly from nostrils
to jaw, in dorsal profile bluntly rounded, lacking rostral keel; canthal
ridge thickened; loreal region deeply concave; lips thick, barely
flared. Nostrils small, barely protuberant, directed anterolaterally,
situated about two-thirds distance from eye to tip of snout; internarial
distance 5.6 mm. internarial area barely depressed near convergence of
canthal ridges; top of head flat; interorbital distance 6.4 mm., 28.3
per cent of head width; diameter of eye 6.8 mm.; width of eyelid 5.5
mm., 24.3 per cent of head width. Heavy dermal fold extending
posteriorly from posterior edge of orbit, covering upper edge of
tympanum; two thinner folds extending ventrally from longitudinal heavy
fold covering posterior edge of tympanum; anterior and ventral edges of
tympanum distinct; length of tympanum 2.9 mm., 42.6 per cent of diameter
of eye.
Axillary membrane absent; arms robust, forearm not noticeably heavier
than upper arm; distinct transverse fold on wrist. Fingers long,
moderately slender; length of fingers from shortest to longest, 1-2-4-3;
discs moderately large, that on third finger larger than tympanum;
webbing vestigial; subarticular tubercles small, conical; terminal
tubercle on fourth finger somewhat flattened; supernumerary tubercles
small, in one row on proximal segment of fourth finger and in two rows
on proximal segments of other fingers; prepollex greatly enlarged,
barely bifurcate; spines not protruding through skin; distal spine much
longer than proximal one (Fig. 2). Heels overlap by about one-third
length of shank when hind limbs adpressed; tibiotarsal articulation
extends slightly beyond snout; heavy transverse dermal fold on heel;
inner tarsal fold heavy, extending full length of tarsus; outer tarsal
fold absent; inner metatarsal tubercle high, elliptical, visible from
above, outer metatarsal tubercle absent. Toes long, slender; length of
toes from shortest to longest, 1-2-5-3-4; fifth toe nearly as long as
third; discs small; subarticular tubercles small, round; supernumerary
tubercles small, in single row on proximal segment of each digit; toes
about three-fourths webbed; webbing extending from base of disc of first
toe to base of penultimate phalanx of third, from base of disc of third
to base of penultimate phalanx of fourth to base of disc of fifth toe.
