it differs in being smaller and slimmer, and in possessing a protoconch with more whorls (2 versus 1¾). These four species are very similar in their gross morphology and probably stem from a common ancestor. However, protoconch whorl numbers suggest that speciation has occurred, which is possible given their geographic isolation on widely separated island localities.
