The "konokono", from the local language in Mauritius and Rodrigues, is a really well known seafood delicacy (small to medium size sea mollusk with a shell). However, I really did not manage to find any scientific related information based on this local name (and we are not here speaking about a snail which lives in Africa and is called also konokono in swahili language).

I join here pictures of one same specimen, supposed to be a konokono.

I am looking for the scientific name of this mollusc species.

Any help would be really appreciated, thank you.
