Some notes on an interesting epitoniid species from the eastern Pacific

摘要

In 2011,Mr. George Sangiouloglou contacted me and requested I look at an unidentified epitonium he acquired from Cocos Island,an island off Costa Rica. Since Helen DuShane had spent years studying the Epitoniidae found in the Panamic-Galapagan faunal province and published a series of papers summarizing her findings, I expected it would be a straightforward matter to identify his specimen. To my considerable surprise,I received the specimen pictured in fig. 1. According to the data accompanying the shell, it was collected by a diver at a depth of 10 ft. and was found at the base of an anemone. This is typical habitat for epitoniums since they are predators or parasites of corals and anemones.
