Diagnoza

Shell elongate, 2.5 times as high as broad. Suture incised. Teleoconch ornament consisting of granulated spiral ribs (two strong and one or two weak) and straight axial ribs (usually 9–10 per whorl) together forming distinct net of elongate meshes with blunt tubercules at intersections.

Porównanie

Intermediate between C. muricata and C. quenstedti. The morphotype with one medial rib is especially close to C. quenstedti but it differs in having broader tubercles. Differs from C.muricata in having much weaker medial spiral ribs. The latter species has the ribs of the same, or almost the same, strength.
