The ‘horned turban’ is well known to people mainly in Japan, Korea, and China as an edible marine snail. The species of Japan and Korea was known as Turbo cornutus Lightfoot, 1786 (Sazae in Japanese; Fig. 1) and the Chinese one as T. chinensis Ozawa & Tomida, 1995 (Nankai-sazae; Fig. 2). The first literature record of T. cornutus was published 250 years ago (Fig. 3) and the name was globally accepted.
