ELACHISTODON, Rei/nhardt. 



A genus distinguished by the possession of gular teeth 

 formed by the projection of the anterior vertebral spines 

 into the gullet. The genus is sometimes grouped with an 

 African genus possessing similar characteristics to form a 

 family of the Dasypeltidce. The necessity of this is somewhat 

 doubtful, considering that the genus Nymphophidium has a 

 commencement of this gular set of teeth in the " two obtusely 

 conical prominences on the base of the skull, one behind the 

 other, not covered by the mucous membrane of the mouth."
