At present, probably only one species of this genus occurs in the Mediterranean Sea.
This is N. anomala, which has been identifed by almost all authors.
Some cite N. turbinata occurring with N. anomala.
Information on the shells, living or empty, is rarely indicated; the age of empty valves may reach several hundreds of thousands of
years.
