auriculidæ

Century Dictionary and Cyclopedia

1. A family of pulmonate gastropods with contractile tentacles, eyes sessile at the inner or hinder bases of the tentacles, rugose teguments, and a spiral shell whose partitions are generally absorbed, and whose columella is plicated. The family is divided into sub-families and many genera. Some of the species frequent banks, generally within tide-limits, others marshes and wet woods, and a few (of the genus Carychium) are almost exclusively terrestrial. See cut under Pythia.
