New records.

Israel • 1 sh; north of Atlit; 32.7433°N, 34.9067°E; depth 40 m; 20 Sep. 2016; coarse biogenic sediment in a pool among rocks covered by coralligenous formations; grab; HELM project (sample NG40_2M); NHMW-MO-112930/LM/0170; size: H 4.5 mm, W 1.4 mm.

Remarks.

We found a single, adult, empty shell. It likely possesses a large paucispiral protoconch, but it is incomplete in our shell. The second spiral cord starts at mid-shell height, the fourth and fifth spiral cords are smooth, and the posterior siphonal canal is shallow. It is brown in color with darker spiral cords. We have not been able to assign it to a species so far, but it is distinctly different from all known Mediterranean species and most likely belongs to the Indo-Pacific fauna.
