1904. Rana hexadactyla, Ferguson, op. cit., p. 500, pi. A., fig. 2. 



In structure this tadpole resembles that of Rana cyanophlyctis, but 

 it is much smaller and more slender and has the tail shallower and longer 

 in proportion, the snout is more produced and the mouth is rather 

 smaller, with the beak shallower. There is a deep groove, with its 

 sides and base sometimes cornified. across the lower lip ; the margin 

 of the upper beak fits into this groove when the mouth is shut. There 

 are no dark spots on the tail, the ventral surface of the head and body 

 is silvery and there are usually silvery spots on the sides of the head, 

 body and tail. The colouration is. however, variable.
