OBSERV. The peculiar shape of the teeth is a character which will 

 readily distinguish this genus from its congeners, to which it is allied 

 by the conformation of the cephalic plates. Its large and bony scales 

 constitute another feature not less characteristic, as also the shortness 

 of its fingers and toes.
