Notes

Cephea octostyla was reported in Queensland waters by Stiansy (1926b, from Rockhampton) and Kramp (1965, from Green Island).

The species was originally described as Medusa octostyla from the Red Sea, and was moved to the genus Cephea by Eschscholtz (1829: 57). Haeckel (1880) seemed confused about this species, in one section of his monograph renaming it as Cephea forskalea (p.574), but later (p. 613) creating the new genus Stylorhiza for it. Stiasny (1921b: 251) believed that Forskål's Medusa octostyla is not the same as Agassiz's Cephea octostyla.
