Santa Maria material examined. Maximum height 7.3 mm width 3.9 mm. DBUA-F 191-9 (1). Malbusca, Santa Maria Island, Azores, Touril Complex, Lower Pliocene.

Discussion. The specimen from the Azores is very poorly preserved and missing its spire. Nevertheless, the sculpture of spiral cords just below the suture and on the base of the last whorl are typical for the species. As discussed by Landau et al. (2013: 323; 2020a: 264) ‘ Acteon ’ semistriatus ( Férrusac, 1822) is a highly variable species in both profile with slender and squatter forms coexisting and in its sculpture that is hugely subobsolete mid-whorl on the last whorl but can persist along the entire last whorl in some specimen.
