PALAEOPERIDINIUM Deflandre, 1934, p.968 ex Sarjeant, 1967b, p.246-247.  Emendation: Evitt et al., 1998, p.46,48.  Taxonomic junior synonyms: Astrocysta, Morkallacysta and Pentagonum, all according to Lentin and Williams (1976, p.150,160,161) - however, Stover and Evitt (1978, p.113-114) retained Morkallacysta.  The name Palaeoperidinium was not validly published in Deflandre (1934) since that author did not designate a type, which he was obliged to do as he was using zoological nomenclature (I.C.Z.N. Article 13b).  No type was designated until Sarjeant (1967b) did so; he also brought the generic name under the auspices of the I.C.B.N. (now the I.C.N.).  This interpretation differs from that in Lentin and Williams (1993) and accords with that of Loeblich Jr. and Loeblich III (1966) and, in essence, also that of Sarjeant (1967b).  In contrast to the contention of Tappan and Loeblich Jr. (1967, p.526), Deflandre (1934, p.968) did publish a description of Palaeoperidinium as a footnote.  In validating the generic name, Sarjeant (1967b, p.246) provided an emended diagnosis.  Type: Ehrenberg, 1837b, pl.1, fig.4, as Peridinium pyrophorum.
