urn:lsid:zoobank.org:act:D76787CE-EE47-4CF2-A8BD-6441C5679776

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.
