Cyclostrema eupoietum

Cyclostrema eupoietum is a species of sea snail, a marine gastropod mollusk in the family Liotiidae.

Description
(Original description by Melvill) The height of the shell attains 1.5 mm and its diameter 2 mm. This is a small, narrowly umbilicated shell with four whorls. The last two whorls are very closely spirally lirately furrowed. The penultimate whorls is puncto-striate. The crenelations round the half-covered umbilicus are large in proportion to the size of the shell. The aperture is round. The peristome is continuous, hardly thickened, a tongue-shaped process, lirato-sulcate as is the rest of the surface, extending over the umbilical region.

Distribution
This species occurs in the Persian Gulf.
