Bahamian Seashells

Megadenus holothuricola Rosén, 1910

This is perhaps the rarest known shallow-water species in the Bahamas. Megadenus holothuricola was described from the Bahamas in 1910 from five specimens that were found living in the respiratory tree of the sea cucumber Holothuria mexicana. Warén (1984) reported that the type material is lost. I know of no published records of this eulimid having been rediscovered since its original description, two photos from which are reproduced (in part) above. These photos of the species in situ show a small white conical shell with what appears to be a cylindrical protoconch of two narrow whorls. Subsequent whorls enlarge rapidly. If anybody has any additional information on this species, I’d be glad to add it here.
