Tongue circular, entire, scarcely free behind. Vomerine teeth in 

 two small transverse groups between the rather large choanal 

 Head much depressed, as long as broad ; snout rounded, once and a 

 half as long as the diameter of the eye ; canthus rostralis very in- 

 distinct ; loreal region not concave; interorbital space a little 

 broader than the upper eyelid ; tympanum very distinct, half the 

 diameter of the eye. Fingers webbed at the base ; no projecting 

 rudiment of pollex ; toes three-fourths webbed ; disks as large as the 

 tympanum ; subarfcicular tubercles moderate. 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, granulate 

 on the bell}* and under the thighs. Light brown above, dotted with 

 dark brown and whitish ; a streak along the canthus rostralis, a 

 cross band between the eyes, and some large spots on the back dark

 of spots on the back, which bifurcates anteriorly ; a spot on the 

 coccyx ; a dark-brown band from angle of eye to scapular region,
