elevated in profile, placed a little nearer tip of snout than shoulder 
or about over last % of gape. Mouth large, gape more or less 
straight, or but slightly undulate, in profile. Lips fleshy, firm, 
upper better developed and closing over lower all way around. 
Lower lip more firm than upper, with slight fleshy knob at sym- 
physis fitting in above. A single series of small, even and more 
or less concealed teeth in edge of upper jaw. No mandibular 
teeth, edges of jaw firm. Vomerine teeth minute, in 2 small 
closely approximated patches, just. after level of middle of in- 
ternal nares. Tongue large, fleshy, thick, elongately ovoid, bulge 
posterior, posterior margin deeply notched medianly, leaving 2 
well-developed fleshy appendages directed down throat, and sur- 
face finely papillose, also porous. Internal nares a little further 
apart than external nostrils. Internal nostrils small, on outer 
front of snout and further apart than bony flattened interorbital 
areas. Loreal region depressed concavely. Tympanum large, 
equals eye-socket, rounded, circular, close behind with about 
lower third below eye, and rictus falling about half way in its 
length. About central third elevated in a shallow prominence, 
and its surface barely granulated. Skin more or less finely 
wrinkled or mammillated, and slight tubercles on sides. A lateral 
glandular fold extends back from eye, convergent posteriorly 
towards vent. This fold bifurcates over tympanum above and 
passes down along its posterior edge to disappear at shoulder. 
A firm elevated keel extends from below loreal region back till 
below middle of tympanum. Fore limb falls near first */, in

Fingers rather slender, and not much enlarged towards bases. 
Third finger longest, about 2 in rest of arm, first a little shorter 
than third, and second and fourth subequally much shorter. Hind
