: fig. 250). Nonetheless, neither Barnard’s description of the ontogeny of the spiral sculpture, nor his statement that the profile of the whorls is biconvex, is compatible with the present material. Likewise, his figure suggests that spiral P1 on the first teleoconch whorl persists as the subsutural cord on subsequent whorls. On this evidence, therefore, I conclude that the Walters Shoal specimens are not conspecific with Barnard’s species.
