Diagnosis
ReferenceDiagnosis
F. S. MacNeil and D. T. Dockery 1984Juveniles of both the type from the Mint Spring Formation and its Byram analog, Cassis mississippiensis Conrad, have a spiral sculpture all over the whorls in which the posterior edge of each spiral band is raised and the anterior edge is depressed. Adults, however, are nearly smooth. The shoulder has prominent thick nodes and there is usually a much weaker staggered set of nodes below the shoulder. At least from the standpoint of the spiral sculpture, juveniles and adults appear quite different (compare figs. 7 and 8, pi. 30).
