Scriniodinium velatum

"?velatum" Conrad, 1941, p.8-9, pl.1, fig.A ex Sarjeant, 1967b, p.256.  Holotype: Conrad, 1941, pl.1, fig.A.  NOW Trithyrodinium?.  Originally Palaeoperidinium (name not validly published), subsequently Scriniodinium?, thirdly Palaeoperidinium? (combination not validly published), fourthly (and now) Trithyrodinium?.  Questionable assignment: Sarjeant (1967b, p.256).  The name Palaeoperidinium velatum was not validly published in Conrad (1941) since the generic name Palaeoperidinium was not validly published until 1967.  Williams et al. (1998, p.550) accepted Sarjeant's (1967b) indirect reference to Conrad (1941) as indication of a type (I.C.B.N. Article 37.1).  Lentin and Williams (1976, p.111) also proposed this name, as a new combination.  Age: Maastrichtian.
