Guildfordia is a genus of sea snails, marine gastropod mollusks in the family Turbinidae, the turban snails.[1]


The imperforate shell is wheel-shaped. It is low-conic and granulose above, convex below. The periphery is armed with long slender radiating spines, which are concealed at the sutures. The operculum is flat, with a subobsolete arcuate rib outside. The central tooth of the radula has no cusps.[2]


This marine genus occurs off the Philippines, Indo-China, Indo-Malaysia, Papua New Guinea, Eastern Indian Ocean, Oceania, and off Australia (Northern Territory, Queensland, Western Australia).
