Bursa ranelloides ( Reeve, 1844)

(Figs 48–49)

1844 Triton Ranelloides – REEVE, pl. 3, fig. 10.

2009 Bursa ranelloides (Reeve) – LANDAU et al., p. 75, pl. 8, figs 1–6, pl. 10, fig. 4 (cum syn.).

Material – Nine specimens (SL 18–23); in private collections.

Description – Fusiform shell, elevated spire, protoconch of three smooth, convex whorls, four subangulate teleoconch whorls, last whorl 74% of the total height, constricted at the base. Ovate aperture, denticulate, angulate outer lip thickened by labral varix, short anal canal, short, slightly recurved siphonal canal, straight, plicate columella. Spiral sculpture of narrow cords, nodulose shoul- der, one row of small tubercles above abapical suture on the spire, three rows of tubercles on the last whorl, axial sculpture of two varices per whorl.

Remarks – The species differs in morphology from B. scrobilator by subangulate whorls with stronger sculpture, and from B. corrugata by narrower shell with sharper tubercles. B. ranelloides is a new record in Hungary.

Distribution – Burdigalian: PMS ( Italy), Badenian: CP ( Austria, Hungary, Romania), Middle Miocene: WA ( Trinidad). For Pliocene-Recent range see LANDAU et al. (2009).
