Cyclostrema gaudens Melvill & Standen, 1912 Munditia gaudens is a species of sea snail, a marine gastropod mollusk in the family Liotiidae.

The small, white shell is deeply umbilicated.

The ribs are longitudinally closely lirate with about twenty two lirae.

The species is lightly allied to Lodderia coatsiana (Melvill & Standen, 1912), but much differing in sculpture, especially in the suppression of the prominent peripheral keeling of the body whorl.

[2] This species occurs in the South Atlantic, in the Magellanic Strait off Argentina at depths between 100 m and 570 m.
