Clanculus rarus

Clanculus rarus is a species of sea snail, a marine gastropod mollusk in the family Trochidae, the top snails.

The description by Dufo was miserable and doesn't allow an undisputed definition. Paul Fischer (1835-1893) suggested that it should be relegated to the synonymy of Clanculus pharaonius.

Description
The size of the shell attains 12 mm.

Distribution
This marine species occurs in the Indian Ocean off the Mascarene basin.
