? Acanthochitona sp. Laghi, 1977, p. 111, pl. 3, figs 10–12; Zanaroli 1985, tab. 2.

Remarks. Four intermediate valves from the Pliocene of “La Tagliata” ( Italy) (MPM n° 1733, max width 3 mm, one of which reproduced here, Fig. 154Q View FIGURE 154 ), that differ from the Acanthochitona spp. here examined mainly for many aspects: the outline of the valve (“anterior margin semicircular”), similar to the outline of the valve figured in Dell’Angelo & Smriglio (1999: fig. 9A), but even more “rounded”; the jugal area not striated longitudinally (as the species of Acanthochitona from the upper Miocene of Saint-Clément-de-la-Place discussed above); possibly by the different shape of the granules, although the low quality Laghi’s figures prevent their accurate evaluation.
