Vomerine teeth in two very small groups close to the inner front 

 edge of the choanse. 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
