Calliostoma euglyptum (A. Adams, 1855) is one of the locally rarer species of the family top snail family Calliostomatidae. Commonly reaching about 18 mm (about ¾ inch), the species has characteristic, slightly rounded whorl sides, and a base without a well-defined, deep umbilicus, the orifice present on the center of the base of other species of the family. The color is dull-rose or orangish-brown, with faint streaks of lighter color.
