Psilaxis radiatus (Roding, 1798)   Maximum size:  16 mm shell diameter (Severns, 2000). Identification:  Shells of this species are disc-like and smooth with the exception of the marginal cords. They are cream with a spiral subsutural brown band and radiating brown lines. They may be distinguished from the shells of Psilaxis oxytropis by their smaller protoconchs that lack brown "staining". Natural history:  Shells of Psilaxis radiatus are rare in beach drift. Live animals are occasionally found in mixed habitats at about 1 m (3 ft). According to Kay (1979), they occur in sand to 50 m (164 ft) and feed on corals of the genus Porites. Distribution:  Big Island, Maui and Oahu (also Johnston Atoll): widely distributed in the Indo-Pacific. Taxonomic notes:  It is listed in Kay, 1979 and Severns, 2000 as Philippia radiata (Roding, 1798). It's listed in Quirk & Wolfe, 1974 and Tinker, 1958 as Philippia hybrida.
