Santa Maria material examined. Maximum height 24.0 mm, width 15.0 mm. DBUA-F 869-2 (1) , DBUA-F 867 (1) , Ponta dos Cedros ; DBUA-F 1295 -D (1), Malbusca (west cave); DBUA-F 161-10 (1) , Pedreira do Campo ; one specimen from LNEG collection (unnumbered), unknown locality, Santa Maria Island, Azores, Touril Complex, Lower Pliocene .

Description. Azorean material too incomplete for description. See Landau & Fehse (2004: 8).

Discussion. The best preserved specimen is an unnumbered complete adult in the LNEG collection, photographed by one of us ( August 2012, SPA). Unfortunately, the specimen is slightly rotated on apertural view, and the photograph out of focus on dorsal view. On a subsequent visit to rephotograph the specimen it could no longer be found ( May 2022, CS). The other Azorean specimens consist of fragments and internal moulds.

Schilderia flavicula ( Lamarck, 1810) and Schilderia garonettii Fehse, 2004 , have a more elongated shell. Zonaria porcellus ( Brocchi, 1814) is much larger with a more produced anterior extremity. Schilderia utriculata is a typically Mediterranean Pliocene species that survived into the early Pleistocene before becoming extinct. This would be the first Atlantic record for the species.

Distribution. Lower Pliocene:?Atlantic, Santa Maria Island, Azores (this paper); central Mediterranean, Italy (Chirli 2008; Sosso & Dell’Angelo 2010). Upper Pliocene: western Mediterranean, Estepona Basin, Spain ( Landau & Fehse 2004); central Mediterranean, Italy ( Sacco 1894; Pavia & Demagistris 1970; Inzani 1985; Fehse 2001 c, 2004), Cyprus, Algeria (Inzani 1985). Lower Pleistocene: central Mediterranean, Italy ( Cerulli-Irelli 1911; Malatesta 1960).
