Csenothermm geoffroyi, Pomel 1 . 



This species is smaller than C. commune, but, like that species, has 

 no diastema. It is recorded by Pomel from Cournon, and by Filhol 

 from St. Gerand-le-Puy ; and it appears probable that the specimens 

 noticed below from Caylux belong to the same species.
