Astralium rhodostomum, common name the rosemouth star shell, is a species of sea snail, a marine gastropod mollusk in the family Turbinidae, the turban snails.[2]

Description

The length of the shell varies between 16 mm and 55 mm. This thick-shelled species stands near to Lithopoma caelatum (Gmelin, 1791), but is distinguished by the following characters: the whorls are flat, not arched, in the middle. The superior nodules are situated near to the suture. They are hemi-spherical and solid. The body whorl has but a single row of nodules. The carina is sharper, the base flatter, with only three concentric nodose lirae. The aperture is lower and more rhomboidal . The color pattern is reddish brown, more or less verging on violet.[3]

Distribution

This species occurs in the Indo-West Pacific and off East India, the Philippines and Australia (Northern Territory, Queensland, Western Australia)
