Baltisphaeridium israelianum Appendix A
"israelianum" (Rossignol, 1962, p.132, pl.2, fig.3) Downie and Sarjeant, 1965, p.91. Holotype: Rossignol, 1962, pl.2, fig.3. NOW Operculodinium. Originally Hystrichosphaeridium, subsequently Baltisphaeridium (Appendix A), thirdly Cleistosphaeridium (combination not validly published), fourthly (and now) Operculodinium, fifthly Cordosphaeridium (combination not validly published). Taxonomic junior synonyms: Cleistosphaeridium cephalum, according to Jain and Garg (1991, p.78); Operculodinium crassum, according to Edwards and Andrle (1992, p.262) — however, Head (1996b, p.1231) retained Operculodinium crassum; and Hystrichosphaeridium westii (name not validly published), by implication in Wall and Dale (1968a, p.315, as "hystrichosphere type x of West"). Motile equivalent: Peridinium (now Protoceratium) reticulatum Claparède and Lachmann, 1859, questionably according to Wall and Dale (1968c, p.272), and without question according to Matsuoka (1989, p.224).
