Description

Adult shells generally range from about 41 to 110 mm in length.

The shell of Cymbiola pulchra is solid, smooth, and glossy, and it is highly variable in appearance. The rounded protoconch consists of three-and-a-half ribbed whorls. The shell has a moderately tall spire that gives the shell an elegant, elongated profile. The whorls are distinctly shouldered, being concave above and convex below the shoulder, and they often bear nodules or short, sharp spines along the angular shoulder. The aperture is long and wide. The lip is bevelled. The columella is slightly concave and shows four plaits. The siphonal canal is deep and narrow.

The coloration typically consists of a white, fawn, or salmon-colored base, frequently marked with three darker spiral bands. In addition, the surface usually displays a pattern of spots, dots, and tent-shaped markings, which can vary widely between subspecies. The columella, or inner shell lip, bears four strong folds, a characteristic feature of volutes.

Distribution

This marine species is endemic to Australia and occurs off Queensland.
