Alvania argentea is a species of minute sea snail, a marine gastropod mollusk or micromollusk in the family Rissoidae.^[1]

Description

The length of the shell attains 3 mm to 4.7 mm.

(Original description) The acuminate-ovate shell is imperforate. The shell contains six convex whorls. It is a beautiful little shining silvery shell, not regularly latticed like Alvania fenestrata, but with the spiral ridges much more prominent than the longitudinal plaits, which are numerous and visible only on the upper half of the whorls. The body whorl is slightly inflated. The aperture is ovate. The columella is arcuate. ^[2]

Distribution

This marine species occurs off Port Elizabeth, South Africa.
