piriformis Conrad, 1941, p.9, pl.1, fig.G ex Sarjeant, 1967b, p.255. Holotype: Conrad, 1941, pl.1, fig.G. Originally Palaeoperidinium (name not validly published), subsequently Gonyaulacysta?, thirdly (and now) Gonyaulacysta, fourthly Palaeoperidinium? (combination not validly published). Questionable assignment: Sarjeant (1967b, p.255) — however, Lentin and Williams (1976, p.111) included this species in Gonyaulacysta without question. The name Palaeoperidinium piriforme was not validly published in Conrad (1941) since the generic name Palaeoperidinium was not validly published until 1967. Williams et al. (1998, p.255) accepted Sarjeant's (1967b) indirect reference to Conrad (1941) as indication of a type (I.C.N. Article 40.3). Lentin and Williams (1976, p.111) also proposed this name as a "comb. nov.". Jan du Chêne et al. (1986a, p.132) recommended that this name be restricted to the holotype. Age: Maastrichtian.
