Discussion

C. baeri is similar to C. angasi and C. sydneyensis. C. baeri can be distinguished by the presence of a strong tooth-like fold at the basal part of its columella and by the weaker sculpture of its last whorl (only a few fine spiral ribs near base). In addition, its spire has a slightly convex outline in late whorls and its late sutural ramps bear a finer spiral sculpture.
