Diagnosis
ReferenceDiagnosis
B. S. Kues et al. 2002The shell surface is characterized by a prominent, elevated, median ridge that bears a narrow selenizone on its crest, and by closely spaced, conspicuous collabral folds that form nodes where they meet the medial ridge and curve gently laterally across the shell surface to the umbilical region. Approximately eight folds are present on the body whorl of a typical specimen. Other than these folds, the shell surface is smooth and lacks ornamentation. The inductura is thickened and knob-like, and undulates where it covers collabral folds early on the body whorl. The lateral lips meet the sides of the body whorl with slight curvature, producing an anomphalous umbilical area.
