Genus Crebrivolutopsius n. gen. Description: Profile high, suture moderately impressed; sculpture of strongly projecting spiral cords, with deeply channeled interspaces along upper part of whorl of broad flattened spiral cords with fine interspaces below periphery, columellar callus narrow; outer lip with numerous prominent teeth along lower margin. Radula with curved rachidian tooth with four subequal cusps; lateral teeth with three cusps. Type species: C. labidentatus n. sp. (HD) Remarks: Crebrivolutopsius shows some anomalous characters that resemble those of the subfamily Neptuneinae, namely the comparatively small nucleus and the tricuspid lateral teeth, but the form and proportions of the shell is Volutopsiinae, so it is provisionally placed in the later subfamily.
