Laguncula pulchella is a species of predatory sea snail, a marine gastropod mollusk in the family Naticidae.
(Original description in Latin) The shell is whitish-glaucous (pale greenish-blue) and ovate-globose (ovoid and somewhat spherical). It is furnished with convex whorls. The surface shows a decussate (cross-hatched) sculpture, which consists of slightly elevated longitudinal lines and oblique lines. The sutures are impressed. The aperture is decorated internally with a broad, pale chestnut band. The columella is of the same color internally.
This marine species occurs off Korea and Japan.
