). It is thinly discoid with a slightly opened umbilicus (ww/dm = 0.43; uw/dm = 0.05) and has a compressed whorl profile that is widest at the rounded umbilical margin; it has fairly strongly converging flanks and a rounded venter. The coiling rate is very high (WER = 2.30). The shell bears barely visible, extremely faint growth lines with a biconvex course and also a shell constriction limited to the inner flank. The suture line has a weakly pouched external lobe that is about two-thirds the depth of the nearly symmetric V-shaped adventive lobe (
