Description

The shell has the same shape as Hydatina physis. It is characterised by thin thick irregular brown lines running across the translucent white shell, essentially parallel to the outer lip of the shell. There are colorless spiral bands around the base and apex of the shell. The color of the soft parts of the animal varies from a pale translucent, almost white form, to a dark pinkish brown form that is edged with white.

Length: 40 mm.
