 The width of adult shells varies from 18 to 25 mm.This section is based on the anatomy of "Ringicella ringens", which is also valid for the genus "Anostoma" (according to 1901 information from Pilsbry).Unlike the shell, the soft anatomy is not especially peculiar, in so far as it is known from Dr. Paul Fischer's (1857) account of "Ringicella ringens".
