|Drawing of a shell of Gibbula multicolor|
(Krauss, 1848) 
The height of the shell attains 6½ mm, its diameter 7 mm. The small, narrowly perforated shell has a conoidal shape with five whorls. The first is whitish-rosy, the following white, with reddish flammules and spots of green and bluish, especially at the ridges. The surface of the whorls is marked with very fine spiral and vertical striae, and 2 elevated carinae. The body whorl contains three keels. The base of the shell is red with a spiral series of green streaks, concentrically striate. The aperture is suboval and smooth within. The columella is white.
(Description of Gibbula fucata) The height of the shell attains 5.6 mm, its diameter 7.3 mm. The elevated shell has a helicoid shape. Its apex is red, the rest variously spotted, streaked and blotched with Indian red, pale yellow, light green and brown. The 2½ nuclear whorls are well rounded and smooth. The postnuclear whorls are marked by four, very strong, rounded, equal, and equally spaced, spiral cords, of which the first is at the summit and the fourth at the periphery. On the last turn the cord at the summit becomes obsolete. In addition to the spiral sculpture the whorls are marked by very retractively slanting, closely spaced lines of growth. The periphery of the body whorl is rendered decidedly angulated by the spiral cord. The base of the shell is short, well rounded, marked on the posterior fourth by six, narrow, flattened, spiral bands and between these and the umbilical chink by seven additional bands of about double the width of the former. The umbilicus is covered with a white callus. The aperture is subcircular and very oblique. The outer lip is thin at the edge and thick within. The columella is strong and decidedly curved. The parietal wall is covered by a moderately thick callus.
This marine species occurs off the southern coast of South Africa.
