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.
