Tongue large and wide behind, faintly emarginate. Vomerine 

 teeth in two groups near the line of the posterior border of the 

 choanse. Head narrow and acuminate ; snout projecting acutely 

 beyond the labial margin ; canthus rostralis distinct, but obtusely 

 rounded ; tympanum one fourth the diameter of the orbit. The 

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

 articulation reaches between the eye and the nostril. Skin of dorsal 

 region tubercular, smooth warts of large and small size being irre- 

 gularly crowded over its entire surface ; belly granulate. Colour
