REMARKS

The specimens recovered from the present material are very close to Costoanachis terebralis (Grateloup, 1834), which is a rather widespread European species. Its members present morphological variations that mainly concern the width of the shell and the spacing of axial sculpture. The present specimens are on the more slender side of the morphology, most similar to the specimens described in A.W. Janssen (1984).

It differs from C. corrugata (Brocchi, 1814) in having a smaller shell and no spiral sculpture, although some very inconspicuous spiral threads are observed between the axial ribs in a juvenile specimen from Felli. The protoconch is multispiral and dome-shaped, the corrosion of the recovered shells does not allow for a detailed description.
