(Figs 101–105, 108)

1893 Conus (Chelyconus) Marii – SACCO, p. 62, pl. 6, fig. 1; varieties: fusulopupoides, ovatopupoides, digitiformis, asparagispira, perfusulospira, clavatoidea, subconicospira, medioventrosa, subpileospira, ovatobrevis, pileospira, mamillatospira: pp. 62–64, pl. 6, figs 2, 4–8, 10–15.

1964 Conus marii (Sacco) – HALL, p. 148, pl. 26, figs 8, 15–16, 21–22 (cum syn.).

2001 Conus (Leptoconus) extensus Partsch – CHIRA & VOIA, pl. 2, fig. 1.

? 2001 Conus (Chelyconus) marii Sacco – CHIRA & VOIA, pl. 4, fig. 2.

Material – 29 specimens.

Description – Shell large (SL: 40–78). Spire elevated, outline convex. Spiral whorls convex. Suture deep. Shoulder rounded. Body whorl elongate, ventricosely conical, smooth on the juvenile specimens, while pronounced ridges appear at the base on the adults. Aperture narrow, straight. Subsutural flexure asymmetrically curved.

Remarks – Some Letkés specimens agree well with the syntype (figured by FERRERO MORTARA et al. 1984, pl. 17, fig. 8). Others are closer to varieties represented by SACCO (1893): C. marii var. digitiformis (l. c., p. 62, pl. 6, fig. 5.); var. medioventrosa (l. c., pl. 6, fig. 11.). Varioconus clavatulus and V. noe (Brocchi) are similar forms, but both differ in much lower spire.

Distribution – Italy (LM), (?) Romania (MM). Hungary: Letkés (MM).
