Description: Distinguished by the large, strongly biconvex test with limbate ventral sutures converging at a median umbilicus; usually 11 chambers in last whorl in adults; aperture extends over periphery and back for a short distance; often a peripheral supplementary aperture at the junction of the last 2 chambers.
Distribution: Upper Whaingaroan to Tongaporutuan.
Comment: Srinivasan (1966, Trans. Roy. Soc. N.Z. geol. 3(17): 249, pl. 4, fig. 5, 6, 11) separated the Eocene and Lower Oligocene (Kaiatan to Lower Whaingaroan) populations as C. pronovozelandicus (smaller, less convex dorsally, more convex ventrally, with sharper periphery and less limb ate sutures).
