Grooved Top Shell

Jujubinus striatus, common name the grooved top shell, is a species of sea snail, a marine gastropod mollusk in the family Trochidae, the top snails.^[1]

Subspecies

• Jujubinus striatus delpreteanus Sulliotti, 1889
• Jujubinus striatus striatus (Linnaeus, 1758)

Description

The size of the shell varies between 6 mm and 13 mm. The small, imperforate, solid shell has an elongate-conical shape. It is brown or yellowish olive, rarely unicolored, striped or lined longitudinally with white, sometimes the striping broken into a tessellated pattern. The surface is dull or shining. The whorls show a much less prominent ridge at the periphery than in Jujubinus exasperatus. The supra-sutural fasciole when discernible, is not projecting nor prominent. The whorls are encircled by numerous subequal lirulae. The interstices are slightly or strongly obliquely striate. The base of the shell contains numerous striae or riblets, about double the number possessed by Jujubinus exasperatus.

This species is distinguished from Jujubinus exasperatus, a species of nearly the same size and outline, by its finer more numerous spiral striae, and a less strongly truncate columella.^[2]
