Description (Described as Acamptochetus) The shells are elongate-ovate to fusiformly elongate. The sculpture is generally cancellate, although spiral elements may predominate. The sutures bear a smooth or cingulate spiral thread, and the whorls frequently show flat, adpressed, and often obsolete growth varices. The aperture is narrow and fusiform. The outer lip is finely or obsoletely denticulate. The columella carries a smooth, narrow callus, and the siphonal canal is moderately short.
