| Abstract |
In this paper fossil species from the Neogene of Southern Europe or the Vienna Basin, and Recent ones from the Lusitanian and Westafrican regions, which have been incorrectly assigned to Nassa semistriata Brocchi, 1814 (= Nassa semistriatus) are described, figured and discussed. It appears that: 1- mostly commonly specimens designated as Nassarius semistriatus belong to N. elatus (Gould, 1845). This is a relatively common species, practically ignored by both zoologists and paleontologists. We have been able to trace it from the Upper Middle Miocene to Recent. 2- Some recent specimens designated as « Nassa semistriata » belong, in fact, to Nassarius cabriensis (Fischer et Tournouër, 1873) subspecies ovoideus (Locard, 1886 sub Nassa ovoidea). This subspecies has also been confused with N. trifasciatus (A. Adams, 1853; non Gmelin) = N. vinctus (Marrat, 1877). 3- less frequently fossil specimens determined as N; semistriatus do, in fact, belong to the Mio-Pliocene species: N. hoernesi (Mayer, 1864), N. gigantulus (Bonelli inMichelotti, 1840), N. badensis (Partsch in Hörnes, 1852). 4-rarely the Pleistocene and Recent specimens assigned to N. semistriatus belong to N. edwardsi (Fischer, 1882). This species is much less common than N. elatus and is mostly Mediterranean. 5- we consider Nassarius recidivus (V. Martens, 1876) to be a recent sub-species of the mio-pliocene species N. macrodon (Bronn, 1831) (= N; reconditus (Mayer, 1873), N. auingeri (Hoernes et Auinger, 1882) et N. crypsigonus (Fontannes, 1882)). 6- we have not seen any recent shell which belongs undoutably to N. semistriatus (Brocchi, 1814). 7- we have observed viviparity in two species: N. elatus (Gould, 1845) and N. cabriensis ovoideus (Locard, 1886). An appendix contains some additions and emendations to a list of fossil species of Nassarius mentioned in Glibert, M., 1963.-Les Muricacea et Buccinacea fossiles du Cénozoique étranger des collections de l'Institut royal des Sciences naturelles de Belgique. (Mémoirs I.R.Sc.N.B., 2me série, fasc. 74, 30 septembre 1963, pp. 111-114). |
