Shells of Spiricella unguiculus are reported from two localities in the Mediterranean, viz. (1) Italy, Tuscan coast south of Livorno, and (2) Tunisia, island of Djerba. At each locality only a single fresh shell was found. S. unguiculus, originally described from Miocene deposits, has only recently been recorded as an extant species from southern Portugal, Algarve (Hoeksema & Janssen, 1984).
