(Fig. 21e)

Material examined. (2 empty shells and 2 with soft parts, in 3 samples): SPAIN • 1 sPc (juv); 43° 40.250′N, 008° 43.755′W to 43° 40.760′N, 008° 42.120′W; 207– 197 m; 10–20 SeP. 2003; DIVA-Artabria I EBS-200 • 1 sPc (juv) + 1 sh; 42° 30.391′N, 009° 19.517′W to 42° 29.428′N, 009° 17.924′W; 147–148 m; 17–28 SeP. 2004; VERTIDOS AG-EBS-150 • 1 sh; 44° 00.806′N, 008° 33.098′W to 44° 01.967′N, 008° 32.57′W; 346– 344 m; 15–24 Jul. 2008; A SELVA EBS-14 .

Remarks. It is a very common sublittoral species, mainly in shallow waters, along all European and North African coasts from Norway to Morocco and throughout the Mediterranean, not present on the Macaronesian islands (Oliver et al. 2019). Very few eroded shells (Fig. 21e) have been found in samples obtained at the depth range of 150–345 m, likely swept by the currents away from the coast.
