Diagnosis
ReferenceDiagnosis
K. Bandel 2007The juvenile shell resembles that of Rimella or Ectinochilus in shape and ornament. When fully grown a callus is added to the slender conical shell and its shape changes due to a broadening of the sides. The callus of the inner lip joins the callus of the margin of the outer lip and extends onto the spire forming a groove and pad. Callus may also cover the surface of the apertural side of the shell. Callus covers part of the shell in Eocalyptraphorus n. gen., and it completely transforms shell shape by additions of callus in Calyptraphorus. The shell of Aulacodiscus is extremely coated over with callus. Cyclomops has the shell similar to Ectinochilus with callus sheets attached to the margins of the apical callus groove and thus broadening the body whorl.
