Kalloconus cf. betulinoides ( Lamarck, 1810)

(Figs 50–52)

1810 Conus Betulinoides – LAMARCK, p. 440.

Material – 28 specimens.

Description – Shell medium-sized (SL: 23–49). Spire low, outline convex. Spiral whorls smooth. Shoulder rounded. Body whorl ventricosely conical, outline slightly convex, smooth with fine ridges at the anterior end. Aperture wide. Subsutural flexure nearly symmetrically curved.

Remarks – The Letkés material contains only juvenile or fragmentary adult specimens. They resemble the neotype (designated by SACCO 1893, p. 4, pl. 1, fig. 1, refigured by DAVOLI 1972, pl. 2, fig. 1), and the specimens figured by DAVOLI (1972, pl. 2, figs 2, 6–7), by BAŁUK (1997, pl. 20, fig. 9) and by MIKUŽ (2009, pl. 12, fig. 163); nevertheless, the use of open nomenclature seems reasonable.

Distribution – Portugal (M), France, Turkey (M-P), Austria (LM-MM), Poland, Slovenia (MM), Greece (MM-UM), Italy, Spain (MM-P), Libya, (?) Malta (UM), Tunisia (UM-LP). Hungary: Letkés, Márkháza, Mátraverebély, Sámsonháza, Budapest: Rákos (MM).
