Slender fusiform shell; obliquely oval aperture; moderately long and twisted siphonal canal; shallow C-shaped anal sinus; thin spiral keels (the most prominent placed halfway between sutures) increasing in number by intercalation during growth; dense and very sinuous superimposed collabral riblets; base with several distinct spiral cords. Protoconch: stout, low conical; slightly less than 2.5 whorls; diameter about 870 µm; height about 840 µm; surface finely granulated; spiral keel at the abapical third; adapical weaker keel high on first whorl, later reduced; faint axial ribs on the last 0.5 whorl; transition to the teleoconch ill-defined, marked by the appearance of the adult sculpture. Occurrence . Box-corer samples BC67 (1 specimen), BC72 (3); core BC72 (1). Maximum height: 8 mm . Distribution and habitat . Drilliola emendata is distributed across the Mediterranean; in the Atlantic it seems to be restricted to Iberian and northwestern African coasts. It is a bathyal species sporadically found at circalittoral depths ( Hidalgo 1917 ; Di Geronimo & Panetta 1973 ; Bouchet & Warén 1980 ; Di Geronimo et al. 2001 ). Fossil record. Upper Miocene to Lower Pliocene of Malaga, Spain ( Vera-Pelaez et al. 1999 ); Pliocene of Sicily ( Monterosato 1872 ; Cipolla 1914 ); Pleistocene of southern Italy ( Di Geronimo 1975 ; Di Geronimo & La Perna 1997; Di Geronimo et al. 2005 ).
