Description

The size of the shell varies between 15 mm and 36 mm. Rather low-conic shell is conspicuously radiately plicate above. The folds are somewhat sigmoid and oblique, bearing a series of short rounded knobs above, and terminating in short spines, eighteen to twenty in number, at the carinated periphery. The base of the shell is flat, squamosely lirate. The aperture is tinged with green, especially at the columella. The wrinkled operculum is deep green.^[3]

Distribution

This marine species occurs off Hawaii, French Polynesia and the Marianas.
