Type material (of Bulla micromphalus Mayer, 1864). Single specimen height 17.0 mm, width 10.0 mm, Pinheiros (Baía da Cré), Santa Maria Island, Azores; whereabouts unknown (Beu 2017:165).

Santa Maria material examined. Maximum height 8.2 mm, width 4.5 mm. DBUA-F 1027-2 (2), Malbusca, Santa Maria, Azores, Touril Complex, Lower Pliocene.

Discussion. Roxania utriculus (Brocchi, 1814) typically has spiral sculpture on the last adult whorl restricted to the extremities, with the central portion of the whorl smooth. All Miocene to extant shells examined have this type of sculpture. However, some Miocene specimens at hand have spiral sculpture extending across the entire last whorl. This form was illustrated by Brunetti & Cresti (2018: 120) under the name Roxania utriculus totornata (Sacco, 1897) which probably should be synonymised. The Azorean specimens are slightly slenderer than usual, the surface is somewhat decalcified but show the characteristic fine spiral sculpture at the extremities. Roxania utriculus is widespread in Miocene to present-day European Atlantic and Mediterranean assemblages. In our opinion, specimens from the Pliocene Santa Maria assemblages originally identified as Bulla utriculus by Bronn in Reiss (1862: 34) and later described as a distinct species, Bulla micromphalus (Mayer, 1864), fall within the variability of Roxania utriculus . Mayer’s species is thus considered a junior subjective synonym herein.
