Reference: Hornibrook, Brazier & Strong 1989, p.99, Fig. 23:13 (after Gibson, redrawn).
Synonymy: 1824, in Blainville, H. M. D. de, Mollusques, vers et zoophytes, in Dictionnaire des Sciences Naturelles, Paris, 32: 176, pl. 13, fig. 6.
Description: Large, smooth, with an initial half coil becoming uniserial; triangular in cross section with thickened limbate keels at the edges of the anterior face.
Distribution: Altonian to Waipipian. Characteristic of some facies of the Upper Miocene and Lower Pliocene. Since it occurs off New Zealand in the Recent, its disappearance in the upper Wanganui Series is probably due in part to shallowing facies.
