ANOSTOMA?*, Fischer. 
Testa orbicularis, sublenticularis, spira obtusé convexa, anfractu ultimo 
abrupté transvoluto ; apertura semilunari, supra spiram reversa, 
utrinque intro dentata; labro externé incrassato, reflexo ; interné 
versus spiram expanso. 
The Anostomata were separated from the Helices by Fischer on account 
of the very singular manner in which the last whorl of the shell is sud- 
-denly turned upwards. It is difficult to account for this extraordinary 
conformation ; for, as Sowerby naturally observes, ‘‘ does it not indicate 
a considerable change in the habits and economy of its animal inhabitant 
* This word, compounded of ava and oropa, should certainly be Anastoma, neuter.
