Gonyaulacysta edwardsii

"edwardsii" (Cookson and Eisenack, 1958, p.32, pl.3, figs.5–6; text-fig.7) Clarke and Verdier, 1967, p.31.  Holotype: Cookson and Eisenack, 1958, pl.3, fig.6; text-fig.7; Jan du Chêne et al., 1986a, pl.32, fig.4; pl.33, fig.3.  NOW Cribroperidinium?.  Originally Gonyaulax (Appendix B), subsequently Gonyaulacysta, thirdly Cribroperidinium, fourthly (and now) Cribroperidinium?.  Taxonomic junior synonyms: Gonyaulax (as Cribroperidinium) apione, according to Burger (1980a, p.82) — however, Jan du Chêne et al. (1986a, p.76) retained Cribroperidinium apione; Gonyaulax (as Cribroperidinium) orthoceras, according to Davey and Verdier (1971, p.17) — however, Below (1981a, p.39–40) and Lentin and Williams (1985, p.79) retained Cribroperidinium orthoceras.  This combination was not validly published in Sarjeant (1966b, p.130), since that author did not fully reference the basionym.  Age: Albian–early Turonian.
