Atlanta helicinoidea is a species of sea snail, a holoplanktonic marine gastropod mollusk in the family Atlantidae. ^[1]

Description

The maximum recorded shell length is 4 mm. ^[2]

(Described in Latin as Atlanta helicinoides) The shell is glassy, disc-shaped, broadly keeled, translucent, and very thin. The spire is very small, protruding, and conical. There are seven whorls, which are convex-depressed, with the body whorl being keeled. This keel is bordered at the base with a rust-colored margin. The aperture is ovate-acute and notched at the front; the peristome (the lip of the shell) is thin and sharp.

The operculum is glassy, oval, thin, translucent, and has only a few spirals. ^[3]
