Vomerine teeth in two very small groups close to the inner front 
edge of the choane. Snout subtriangular ; canthus rostralis distinct; 
loreal region slightly concave; nostril nearer the tip of the snout 
than the eye; interorbital space a little broader than the upper 
eyelid ; tympanum half the width of the eye. Fingers very slightly, _ 
toes nearly entirely webbed ; disks nearly as large as the tympanum ; 
subarticular tubercles moderate ; a small inner metatarsal tubercle. 
The hind limb being carried forwards along the body, the tibio- 
tarsal articulation reaches between the eye and the tip of the snout. 
Skin smooth, granular on the belly and under the thighs ; a fold - 
above the tympanum; lower surface of forearm and tarsus tuber- 
cular. Greyish above, indistinctly marbled with darker; limbs 
cross-barred ; throat speckled with brown. From snout to vent
