Specimens (n = 30) from Giglio Island: 5.5 - 17.0 mm (mean: 11.0 mm ± 0.6 mm) height; 5.2 – 16.8 mm (mean: 10.8 ± 0.6 mm) width. Ratio [h/w] = 1.03 ± 0.006. Aperture approximately 80 % of shell height. The larval shell has a diameter of approx. 135 µm. General shape: Globose, slightly elevated spiral whorls, rather thin, 5.5 [teleoconch: 4] whorls. Sculpture: Axial wrinkles on shoulder; fine growth striae. Shell color: Whitish-cream, yellowish-grey or light-brown with three distinct horizontal white bands with chevron-shaped brown marks; one band on shoulder, one around periphery, broadest band with somewhat fuzzy marks encircles umbilicus; in addition, unmarked yellowish band below suture. Protoconch: Dark protoconch, 1.5 embryonal whorls. Aperture & outer lip: Aperture half-moon shaped, oblique, angled at the top; outer lip simple, sharp; basal lip slightly drawn out. Umbilical area : Open umbilicus; relatively large, centrally located whitish funicle; funicular callus slightly enlarged, merging anteriorly with columellar callus which is tapering towards basel lip; distinctive sulcus; distinct, whitish parietal callus. Operculum : Calcareous, glossy, with a deep, broad (as broad as ribs) furrow in front of two distinctive, massive ribs separated by a narrow ridge next to outer lip. Animal : Propodium and mesopodium translucent whitish-grey, speckeled with red, irregularly shaped dots; dots more dense on propodium, which appears darker colored than mesopodium; when extended, mesopodium twice the length of the shell; propodium about as long as the shell; tentacles nearly as long or longer than propodium, colored with red dots on a whitish grey background, similar to coloration of foot. Egg mass: Rigid, multispiral, even-walled coil of mucus-cemented sand grains (Figs. 3, 11 C,D,E/c,d,e), 3–5 circles; outer diameter 20–40 mm (N = 6; mean: 30.25 mm ± 7.961 [SD]). Differential diagnosis : This species cannot be confused with any other Mediterranean species; distinct morphological features include the operculum with the furrow in front of two distinctive, thick ribs next to the outer lip; the reddish color pattern of the shell and foot, the long tentacles, and the elongated mesopodium. Geographical distribution Giglio Island: Cala dell´Allume (4), Pt. del Corvo (5), Pt. del Morto (6), Cannelle Bay, Pt. della Campana (7), (8), Pt. delle Secche (3) General distribution: Common in the entire Mediterranean Sea and the Eastern Atlantic, South to Ghana (Villa 1986), and offshore to the Cape Verde Islands (Rolán 2005). : Published as part of Huelsken, Thomas, Marek, Carina, Schreiber, Stefan, Schmidt, Iris & Mann, Michael Holl-, 2008, The Naticidae (Mollusca: Gastropoda) of Giglio Island (Tuscany, Italy): Shell characters, live animals, and a molecular analysis of egg masses, pp. 1-40 in Zootaxa 1770 on pages 22-23, DOI: 10.5281/zenodo.182119 : {"references": ["Weinkauff (1867) Die Conchylien des Mittelmeeres, ihre geographische und geologische Verbreitung.
