Tongue circular, slightly nicked and free behind. Vomerine 

 teeth in two Small groups between the choanse. 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 (h) 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 i and Tc show 

 the reverse, the brown covering the upper surfaces, the white being 

 reduced to a triangular spot on the forehead, a spot on scapidar
