Vomerine teeth in two small oblique groups between the choanse, 

 frequently missing. Head much elongate; snout long, rounded, 

 with angular canthus rostralis and deeply concave loreal region;

 distinct, about one third the width of the eye. Fingers slender, 

 first shorter than second, with very large disks ; toes very broadly 

 webbed, with moderate disks ; subarticular tubercles rather small. 

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

 Fingers slender, first extending a little beyond second ; toes moderate,
