Tongue circular, slightly nicked and free behind. Vomerine 
teeth in two small groups between the choane. Head rather small, 
broader than long ; snout rounded, as long as the diameter of the 
orbit; canthus rostralis distinct ; loreal region nearly vertical, not 
concave ; interorbital space broader than the upper eyelid; tym- 
panum more or less distinct, half the diameter of the eye. Fingers © 
nearly two-thirds webbed ; no projecting rudiment of pollex ; toes 
nearly entirely webbed ; disks nearly as large as the tympanum ; 
subarticular tubercles moderate. The hind limb being carried for- 
wards along the body, the tibio-tarsal articulation reaches between 
the eye and the tip of the snout. Skin smooth, granulate on the 
belly and under the thighs. Upper part of head and back yellowish 
or whitish; sides of head and body, and a large marking on upper 
surface, brown, the two colours sharply defined ; this brown mark- 
ing represents generally a hourglass-shaped figure, which may be 
prolonged posteriorly into two branches confluent with the brown 
of the sides, thus enclosing an oval light space on the pelvic region. 
In one specimen (a) the brown mark is spotted with white; in 
another (/) it is reduced to a triangular isoscelous spot on the head 
and nape; another specimen (¢) lacks entirely the brown marking, 
and the upper surfaces are uniform whitish ; specimens 7 and k show 
the reverse, the brown covering the upper surfaces, the white being 
reduced to -a triangular spot on the forehead, a spot on scapular
