Diagnosis
ReferenceDiagnosis
C. H. Holland and P. Copper 2008Maximum length 72 mm, average diameter ca. 40 mm; rate of increase about 158. Foerste found nearly nine camerae in a length equal to conch diameter, but his illustration (pl. 46, fig. 1) suggests a figure closer to seven, and the new material suggests less than this. Septa direct, concave to ca. 1.5 camerae; siphuncle <40% of conch diameter, eccentrically placed; two and a half segments occur within a length equal to diameter; their outline is convex.
