Eulimella scillae ( Scacchi, 1835) — Cossignani et al. 1992 (fig. 202); Van Aartsen 1994 (p. 98, fig. 17); Petersen 2004 (p. 52, fig. 33); Repetto et al. 2005 (p. 228, bottom right fig.); Høisaeter 2014 (p. 59, figs. 99–100).

Diagnostic characters. Turreted straight-sided shell; whorl face straight to very slightly convex with narrow subsutural shoulder; body whorl roundly angular at the periphery at transition to base; ovate-quadrangular aperture; outer surface with faint growth lines only. Protoconch: heterostrophic, globose/helicoid (type A sensu Van Aartsen 1987), transaxial; 1.7 whorls; diameter about 260 µm; surface smooth; transition to the teleoconch marked by a simple lip.

Occurrence. Box-corer sample BC72 (1 specimen). Height: about 2.5 mm.

Distribution and habitat. Eulimella scillae is distributed from northern Norway and Iceland to the Barents Sea and southward to the Caribbean, the Canaries, Cape Verde and the Mediterranean; it dwells on muddy sand, sand, clay, shell gravel or mixed bottoms from infralittoral to bathyal depths ( Fretter et al. 1986; Poppe & Goto 1991; Barash & Danin 1992; Di Geronimo et al. 2001; Petersen 2004; Høisaeter 2009, 2014).
