Shell description

The shells of species in this genus are moderately large to very large, range size from 14 mm (''Bullata largillieri'', smallest species of ''Bullata'') to 97.9 mm (largest specimen known of ''Bullata bullata''). (pl I) The shell color is a yellowish-orange to orange- or pinkish-brown, spirally banded (pl II) or with white spots (pl III). The lip is pink, yellow, or orange, darker than shell color (pl IV). The shell surface is smooth and glossy. The shape is elliptical to oblong or obovate, moderately to strongly shouldered (pl V bottom). The
