Propebela aff. turricula (Montagu, 1803) (Fig. 12G 1-G 3)

MATERIAL AND DIMENSIONS. — Maximum height 10.7 mm, width 4.4 mm. — RGM.1365012 (90+), leg. ACJ; RGM.1365294 (21), leg. ACJ; RGM.1364929 (31), leg. WG; RGM.1365291 (1), leg. AWJ; RGM.1365117 (115), leg. AWJ .

SPECIES CHARACTERISATION. — Small fusiform shell. Two smooth protoconch whorls. Three quadrate teleoconch whorls separated by well-defined swallow suture. Sculpture consists of two spiral cords conferring the quadrate aspect of the whorls; and around 15 opisthocline axial ribs. Last whorl is covered by numerous spiral cords and ribs, continuing on the base. Well developed columelar lip. Elliptical aperture, with a short, widely open siphonal canal.

DISTRIBUTION. — Lower Pleistocene: Atlantic, Selsoif (this paper).

REMARKS

Even though Propebela turricula has a wide morphological variability particularly in material from the Quaternary of the NSB (Raad et al. 2016), the elongate-shaped specimens with well pronounced ribbing from Selsoif appear to fall outside the range of variation. Further study is required to establish whether this might represent a new species.
