Palaeohystrichophora muriciformis

?muriciformis Conrad, 1941, p.7, pl.1, fig.k ex Sarjeant, 1967b, p.253.  Holotype: Conrad, 1941, pl.1, fig.k.  Originally Palaeoperidinium (name not validly published), subsequently (and now) Palaeohystrichophora?.  Questionable assignment: Sarjeant (1967b, p.253).  The name Palaeoperidinium muriciforme was not validly published in Conrad (1941) since the generic name Palaeoperidinium was not validly published until 1967.  Williams et al. (1998, p.453) 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.110) also proposed this name, as a new combination.  Age: Maastrichtian.
