This genus has been divided into sections on the basis of the den- 

 ticulation of the jaw, as follows : 



Jaw without denticulations. Oxyloma (hungaricd). 

 Jaw with a single median denticle. Amphibina {pfeifferi ). 

 Jaw with a minute median denticle. Lucena (oblonga). 

 Jaw with three denticles Neritostoma. = Succinea s. s. 



According to this scheme S. avara is an Amphibina, S. totteniana 

 a typical Succinea, while S. ovalis (Say) Morse has seven denticles 

 and is unprovided for. The differences among the few species which
