Tongue broader than long - , openly emarginate, and slightly free 

 behind. Vomerine teeth between the very large choanal in two 

 series, forming together an arch the convexity of which is turned 

 forwards. Head large, broader than long ; derm of head involved 

 in the rugose cranial ossification ; posterior outline of casque openly 

 emarginate ; snout rounded, the tip vertically truncated, about once 

 and a half as long as the diameter of the orbit : the distance 

 between the nostril and the eye is considerably greater than the 

 diameter of the latter; can thus rostralis angular, straight; loreal 

 region not very oblique, concave ; crown slightly concave ; inter- 

 orbital space nearly three times the width of the upper eyelid ; 

 tympanum very distinct, two thirds the diameter of the eye. Three 

 outer fingers one-third webbed ; no projecting rudiment of pollex ; 

 toes three-fourths webbed. The hind limb being carried forwards 

 along the body, the tibio-tarsal articulation marks the front of the

 free behind. Tomcrine teeth between the very large ehoana?, in 

 two straight or slightly arched oblique series, convergent towards 

 front. Head rather large, broader than long, rough, bony, the 

 derm involved in the cranial ossification; snout rounded, the 

 tip vertically truncate ; loreal region oblique, concave ; canthus 

 rostralis curved, forming a sharp elevated ridge ; crown concave ; 

 interorbital space very broad, measuring the distance from the eye 

 to the tip of the snout ; hinder edge of casque raised, doubly 

 convex ; a supratympanic ridge : tympanum very distinct, two
