Material – 152 specimens.

Description – Shell medium-sized (SL: 18–48). Spire narrow, low, outline convex. Spiral whorls smooth, convex. Shoulder rounded. Body whorl ventricosely conical, outline sigmoid, smooth with fine ridges at the anterior end. Colour pattern consists of spiral stripes of thin, widely spaced dashes or quadrangular patches. Well-developed, bent columellar fold. Anterior notch developed. Aperture wide. Subsutural flexure almost straight, oblique.

Remarks – The lectotype ( DA COSTA 1866, pl. 9, fig. 23) was designated by SACCO (1893: 12), and refigured by GONÇALVES & MONTEIRO (2012). The species is very similar to L. cacellensis (da Costa) in overall shape, but the latter is fully ornamented by widely spaced spiral ridges on the body whorl (see GONÇALVES & MONTEIRO 2012). Varioconus clavatulus differs in much higher spire with less raised whorls, in less developed siphonal bend, and in asymmetrically curved subsutural flexure. Some specimens (Figs 59–61) are close to the high-spired examples illustrated by DAVOLI (1972, pl. 6, figs 4, 9). The overall morphology of the specimen represented by EREMIJA (1971) agrees well with that of the lectotype of L. eschewegi .
