canthus rostralis ; orbits prominent ; iris wider than high ; interorbital 
space slightly more than half length of orbit; side of head between 
orbit and margin of jaw, slightly concave; tympanic membrane rela- 
tively smooth, oval, slightly higher than wide, separated by half its 
width from orbit, the surface practically continuous with side of 
head ; narrow ridge from posterior margin of orbit extending obliquely 
over tympanic membrane to anterior end of dorsolateral fold; broad 
flattened fold of skin extending backward in line with upper jaw from 
angle of mouth to above fore limb ; fore limb slender ; exposed portion 
of upper arm nearly as long as forearm ; hand longer than forearm ; 
palm with two juxtaposed tubercles; digits slender, without webs, 
rounded at tips, in order of decreasing length, 3, 4, 1, 2 ; sacral hump 
prominent ; dorsolateral folds passing to either side of hump ; hind 
limb long and of heavy build; femur slightly longer than tibia; hind 
foot long, nearly one and a half times length of femur ; one conspicu- 
ous inner metatarsal tubercle; toes long, thickened at base, in order 
of decreasing length, 4, 3, 5, 2, 1 ; web extensive, reaching ends of 
penultimate phalanges except on fourth toe where two phalanges are 
free. 
Tongue narrow, about half width of mouth at angles of jaws, 
anterior end pointed, general shape cuneiform, posterior end with two 
narrow lobes, attached by anterior two-thirds to floor of mouth; 
internal nares well behind tip of snout, and widely separated ; vomer- 
ine teeth large, in two conspicuous clusters between internal nares; 
maxillary teeth large and closely spaced. 
Fore part of head smooth; entire dorsal surface of body behind 
orbits, including sides of body below dorsolateral folds and exposed 
surfaces of hind limbs, with small rounded rough papillae 1 to 2 mm. 
in diameter; midventral surface of body smooth; under surface of 
femur areolated; buttocks rugose. 
General ground color of upper surface buffy brown to olive brown, 
somewhat darker posteriorly ; ground color of fore part of head ecru- 
olive, palest along posterior margin of upper jaw, the whole with 
slight bronzy iridescence; margin of jaw, in narrow line between 
nostril and eye, and lower border of ridge running backward from 
orbit, dusky ; pupils black, iris black with scattered xanthophores of 
colonial buff ; narrow line along fore and hind margin of iris, colonial 
buff ; tympanum grape green and dusky in irregular pattern, sharply 
set off in color from surrounding skin which contains much dragon’s 
blood red ; dorsolateral folds ecru-olive, slightly differentiated in color 
from rest of back; back and sides of body with blackish spots, each 
with a light bronzy central papilla, these smallest and palest anteriorly, 
larger (up to 5 mm. in diameter) and more conspicuous near urostyle ; 
exposed surface of fore limb, ecru-olive; large spot at junction of 
forearm and body, another on outside of ‘ elbow, ’ a third midway of 
forearm, and others inside of elbow and near forefoot, black; ground 
color of undersurface of body, white, mottled with dusky ; sides of 
body and undersurfaces of hind legs between dusky mottlings, 
dragon’s blood red; dorsal surface of hind foot, inner surface of crus, 
and thigh (except outermost surface), marked with dragon’s blood
