About Tritia corniculum (Olivi, 1792)
The shell of Tritia corniculum is ovate and conical, with a thick, smooth structure that comes to a point at its summit. Shell length ranges from 8 mm (0.3 in) to 20 mm (0.8 in). The spire is made up of six or seven slightly distinguishable whorls, and the suture between whorls is moderately deep. A small number of transverse striae are present at the base of the body whorl. The aperture is quite large, ovate, violet or chestnut-colored, and widens toward the middle. The outer lip is sharp and bears small teeth along its inner surface. The left lip is thick and partially covers the entire length of the columella. The thin epidermis is greenish-brown or reddish-brown; beneath the epidermis, transverse bands can be seen, along with spots of slate-gray or violet-gray. There is also a decurrent white band at the suture, marked with brown or bay-colored articulated spots. This species is found in the Mediterranean Sea, and in the Atlantic Ocean off the coasts of West Africa and the Azores.
