The genus Euspira Agassiz in Sowerby, 1837 on Giglio Island

Two species of the genus Euspira were found on Giglio Island. Euspira nitida (Donovan, 1804), which is frequently listed under one of its many junior synonyms such as Lunatia poliana (Delle Chiaje, 1826) (e.g., Settepassi 1970, Sabelli & Spada 1977, Schiró, 1977, Riedel 1983), and Euspira macilenta (Philippi, 1844) . Specimens of E. nitida were found in the Bay of Campese and in the caves of the Cala delle`Allume in shallow waters up to 8 m depth. Both collecting areas were overgrown with Posidonia oceanica or Zostera spec . sea weeds. The specimens were found crawling under the sand, leaving well observable trails on its surface. Additionally, many empty shells were found in the Caves at the Cala delle´Allume. The species prefers coarse sediment. The one shell of E. macilenta was found at Pt. del Morto in 35 m depth in coarse sand.
