Solatisonax alleryi (Seguenza G., 1876) — Beck et al. 2006 (p. 83, bottom fig.). Diagnostic characters . Conical-depressed shell; rather low spire; roundly trapezoidal aperture; narrow and deep umbilicus bordered by a row of pointed knobs; spiral rows of granules; sharp peripheral keel; strong spiral cord encircling the umbilicus. Protoconch: heterostrophic; about 2 whorls; first whorl deeply immersed, last whorl bulging from the top of the spire; diameter about 770 µm; surface smooth; transition to the teleoconch marked by a thin, everted lip. Remarks . It is of note that the original spelling allerii was modified in 1878 by Monterosato, and the new spelling alleryi has been exclusively used for this taxon afterwards (cf. Bieler & Petit 2005 ). Occurrence . Box-corer samples BC11 ( 1 specimen ), BC67 (4), BC71 (7), BC72 (7); cores BC04 (2), BC21 (1), BC51 (5), BC67 (2), BC72 (6). Maximum diameter: 8 mm . Distribution and habitat . Solatisonax alleryi ranges from the eastern Atlantic (including seamounts) to eastern Mediterranean, dwelling on mud at circalittoral to bathyal depths (Melone & Taviani 1984; Beck et al. 2006 ). The Indopacific specimens reported by Bieler (1993) come from mud, sand and stones of the lower sublittoral zone ( 178–430 m ). Fossil record. Pliocene of Tuscany , central Italy ( Bogi et al. 2002 ); Pleistocene of southern Italy (Melone & Taviani 1984; Di Geronimo & La Perna 1997; Di Geronimo et al. 2005 ).
