Calliostomatinae is a subfamily of gastropods, belonging to the family Calliostomatidae. [1]
They are somewhat large sea snails - marine gastropod mollusks, with gills and a thin, circular, corneous, and many-whorled operculum. Their shell is conical with angular periphery. The spiral sculpture consists of raised cords, in many cases strongly beaded. The protoconch has a raised hexagonal pattern. The columella is simple above, not folded, and either simply concave below or slightly truncate and toothed. The radula has the rhachidian and 4 to 5 lateral teeth with irregularly oval body, and rather long, pointed cusps, their outer edges serrate. The inner marginal teeth are enlarged. The pseudo-proboscis of the animal is well developed [2] [3]
