Hipponix (Antisabia) foliaceus (Quoy and Gaimard, 1835).
(Synonym: Hipponix antiquatus Linnaeus, Tryon, 1886.) Length, 15 mm; diameter, 12 mm. Shell: limpetlike, oval, with concentric lamellae; apex projecting over posterior edge of shell; white. Protoconch: flattened-neritoid, of one and one-quarter whorls; apical whorl smooth, abapical whorls with spiral grooves; colorless to light tan. Sculpture: irregular, platelike, concentric lamellae and fine radial striae. Color: white; ventral shell margin often black. Animal: head, tentacles, and mantle white; foot white, edged with gray; tip of penis bifid (Cass, 1967).
These mollusks are common on the undersurfaces of rocks in tide pools and on fringing reefs; beachworn shells are abundant in drift. Veliger larvae are common in the plankton of Kaneohe Bay, Oahu in August (J. B. Taylor, 1975). Shells are common in the windward islands but found only on Laysan among the leeward islands.
H. foliaceus is reported from many localities in the Indo-West Pacific, and from the west coast of the Americas (Keen, 1971; Cowan, 1974).
