| M. Harzhauser and T. Kowalke 2002 | The broad, coeloconoid shell measures up to 21 mm in height and 23 mm in width. The smooth, strongly convex protoconch consists of one or slightly more than one whorl. It measures 0.08 mm in the width of the initial cap, 0.18 mm in diameter of the first whorl and 0.54 lrun in maximum diameter. No distinct boundary to early teleoconch whorls is present. The early teleoconch is sculptured by four spiral ribs; later whorls bear five strong spiral ribs which are crossed by thin, robust axial lamellae. The lameIlae are collabral and prosocline. Lalnellae and spiral ribs are strongest developed close to the periphery. The points of intersection of axial and spiral sculpture lnay bear nodes. On adult whorls a deep, broad furrow develops between the two anterior spiral ribs, with very prominent oblique axial lamellae. The fiat conical to slightly convex base bears 6-7 spiral ribs. A narrow, deep umbilicus is present. The columellar lip is bent towards the umbilicus with a weak fold. |
