Three Acanthocardia species, namely A. paucicostata (Sowerby 1841), A. bianconiana (Cocconi 1873) and a new species herein described are particularly similar to each other, sharing some shell characters: shell relatively thin-walled, compared with the congeners, tending to be antero-posteriorly elongate, bearing a low number of radial ribs (15-18). A. paucicostata is an extant species with a stratigraphic distribution ranging back to the Late Miocene at least. A. bianconiana, regarded as a variety or subspecies of A. paucicostata in the past literature, had a Plio-Pleistocene Mediterranean distribution. The new species, A. brunettii n.sp., the smallest Acanthocardia species so far known and with an unusually elongate shape, also had a Plio-Pleistocene distribution. There are evidences that the paucicostata group also had representatives in the Miocene, either in the paleo-Mediterranean or the Paratethys. New taxon: Acanthocardia brunettii n. sp. 12 pp., 7 figs, 4.…

Three bathyal species of the family Eulimidae are reported from the Pleistocene of Southern Italy, Eulima bilineata Alder, 1848, Melanella seguenzai n. sp. and Campylorhaphion famelicum (Watson, 1883). M. seguenzai n. sp. is markedly close to the Recent Mediterranean Melanella glypta Bouchet & Warén, 1986. Haliella tyrrhena n. sp., possibly from the Pleistocene as well as from the Holocene, is described from bathyal bottoms in the Tyrrhenian Sea. It is notably close to H. canarica Bouchet & Warén, 1986 from the Canary Islands. Other incompletely known deep-sea eulimids from the Mediterranean Pleistocene are briefly discussed. 9 pp., 33 figs, gr. 8. …
