Original Description (from Dall, 1892, p. 349):
“Shell with sharply cut radiating threads and riblets, rarely dichotomous, stronger than in the typical form, yet not reaching the strength of the ribs in C. costatum. From the Older Miocene of the Chipola River, a mile below Bailey’s Ferry, Burns. All the specimens from this horizon appear to have this particular sculpture, which otherwise would hardly have authorized the application to them of even a varietal distinctive name.”
