Santa Maria material examined. Maximum height 1.9 mm, width 1.1 mm (incomplete fragment). DBUA-F 1023- 2 (1), Ponta do Castelo, Santa Maria Island, Azores, Touril Complex, Lower Pliocene.
Description. Azorean material too incomplete to offer a description.
Discussion. The Azorean specimen consists of half of the penultimate and last whorls, attached to matrix that cannot be removed. Nevertheless, it shows the characteristic sculpture consisting of four primary cords: two weaker adapical and two stronger abapical cords. Fine lamellar axial sculpture makes the cords weakly to moderately beaded. The specimen from the Atlantic Lower Pliocene Guadalquivir Basin assemblage illustrated by Landau et al. (2011: pl. 22, fig. 3) as Mathilda granosa (Borson, 1821) represents M. quadricarinata (Brocchi, 1814). Mathilda granosa has one weaker adapical cord and two strong abapical cords that are far more strongly tubercular than in M. quadricarinata (see Sosso & Dell’Angelo 2010: 66, unnumbered figure, middle row centre vs. middle row right). Mathilda cochlaeformis Brugnone, 1873, also from the present-day West African and Mediterranean coasts, differs in having a wider apical angle, two weak adapical cords and the third cord stronger than the fourth, making the whorls somewhat angular in profile. Mathilda gemmulata Semper, 1865, known from the Italian Pliocene and present coast of West African, is slightly slenderer than M. quadricarinata, and has one weak adapical primary cord and two stronger adapical cords.
Distribution. Lower Miocene: central Proto-Mediterranean, Italy (Sacco 1896a). Upper Miocene: central Proto-Mediterranean, Italy (Sacco 1896a). Lower Pliocene: Atlantic, Santa Maria Island, Azores (this paper), Guadalquivir Basin S. Spain (Landau et al. 2011); central Mediterranean, Italy (Cavallo & Repetto 1992; Sosso & Dell’Angelo 2010; Chirli 2013; Brunetti & Cresti 2018). Upper Pliocene: western Mediterranean, Estepona Basin, S. Spain (NHMW collection), France (Chirli & Richard 2008); central Mediterranean, Italy (Sacco 1896a; Caprotti 1976; Tabanelli et al. 2021). Lower Pleistocene: eastern Mediterranean, Rhodes Island (Chirli & Linse 2011). Present-day: Portugal, Mediterranean, West African coast to Angola, Madeira, Canaries and Cabo Verde (Poppe & Goto 1991; Hernández et al. 2011; Giannuzzi-Savelli et al. 2014).
