Their relatively big shell has an onic[check spelling] or turriform shape with a common, prominent, spiral sculpture. The radula shows a rhachidian tooth with no basal cusps. Their stomach has a caecal appendix at its pyloric end. They have a Hydrobia-like central nervous system, a simple penis and a characteristic, big seminal receptacle at the end of a prominent spiral of the coiled oviduct.[2]
