Description

Size: Up to 39.8 mm m.o.d. ( Spain, Hutsell et al., 2001). Specimens (n = 38) from Giglio Island 4.5 – 21.7 mm (mean: 11.4 mm ± 0.9 mm) height; 6.0 – 30.5 mm (mean: 15.8 ± 1.2 mm) to width. Ratio [h/w] = 0.72 ± 0.006. Aperture approximately 87 % of shell height. The larval shell has a diameter of approx. 780 µm ( Giglioli 1955).

General shape: Subglobose, depressed shell with extremely low spire; 4.5 [teleoconch: 2.25] spiral whorls; last whorl extremely wide, constituting most of the shell.

Sculpture: Minute axial growth striae.

Shell color: Glossy; greyish-white to greyish-brown; lighter whitish, indistinct band at periphery; funicular callus greyish (small shells) or reddish (large shells); yellowish brown band beneath suture. Protoconch: Weakly reddish, flat; 1.75 embryonal whorls.

Aperture & outer lip: Broadly half moon-shaped aperture, oblique, rounded at bottom, slightly angled posteriorly; outer lip simple, thin.

Umbilical area: Wide umbilicus, almost completely (sometimes entirely) occupied by large, thick funicle with button-like, reddish funicular callus.

Operculum: Corneous, honey-colored.

Animal: Propodium and mesopodium completely white, almost entirely covering the shell, including spire; propodium as long as mesopodium, each twice as long as shell; width of mesopodium twice the width of shell, broadens posteriorly; width of propodium equals width of shell.

Egg mass: Rigid, coiled paucispiral band of mucus-cemented sand grains with inwardly cambered walls ( Figs. 3View FIGURE 3, 8AView FIGURE 8 /a, 8 J,K), one circle; outer diameter: 51.0 to 59.0 mm (n = 2; mean: 55.0 mm ± 5.7 [SD]). Differential diagnosis: As a typical Neverita  species, N. josephinia  has a very flat outline; its shell is much wider than high (r = 0.72 ± 0.006 [SEM]) which is unique for Mediterranean naticids outside the genus Sinum  ; the animal is very large, and it is able to cover most parts of the shell with the propodium and mesopodium.

Geographical distribution

Giglio Island: Campese Bay (1), Pt. del Faraglione (2), Cannelle Bay (8). General distribution: Strictly Mediterranean, and very commen in the entire Mediterranean Sea.
