Shell moderately large, up to 51 mm. (2 inches) in length, rather flat, elongately ovate, with a weakly scalloped margin, and a flattened apex at about the anterior third. Sculpture consisting of about 100 or more fine, crisp, slightly scabrous radials of varying sizes, and in addition there are the 9 broadly rounded, radial folds, similar to those of the enneagona subspecies of radiata; although little raised, these folds are quite distinct in all the material examined. Colour of exterior, olive to pinkish grey, with 9 broad, radiate bands of dark purplish brown; internally the spatula is white to bluish-grey, the remaining area with the external purplish brown radials showing through strongly; the narrow interspaces, corresponding to the external folds, are bright golden-yellow; the whole highly iridescent. Length: 36-51 mm; Width: 28-41 mm; Height: 10-12,5 mm.

This is a moderately large, rather thin-shelled limpet of low elevation, easily recog¬nised by its striking colour pattern of nine broad purplish brown radial bands, separated by narrow golden-yellow rays; there is a whitish spatula, and the whole of the interior is highly iridescent.
