Vomerine teeth in two short transverse series behind the level of 

 the choange. Snout rounded ; eanthus rostralis rather indistinct ; 

 loreal region not concave ; nostril nearer the eye than the tip of the 

 snout ; interorbital space broader than the upper eyelid ; tympanum 

 indistinct, about half the diameter of the eye. Outer fingers half 

 webbed, toes three-fourths webbed ; disks of fingers about half the 

 diameter of the eye, of toes rather smaller ; subarticular tubercles 

 moderate ; a small, conical, inner metatarsal tubercle. The hind 

 limb being carried forwards along the body, the tibio-tarsal articu- 

 lation reaches the front of the eye. Skin smooth above, granulate 

 beneath ; a short transverse flap of skin on the tibio-tarsal articu- 

 lation. Upper surfaces bright yellow ; lower surfaces and sides of

 backwards a little beyond, the choanie. Snout subtriangular ; can-

 equally distant from the eye and the tip of the snout ; interorbital 

 space as broad as the upper eyelid ; tympanum two fifths the width
