"?paulinae" (Valensi, 1953, p.48, pl.12, fig.6) Davey and Williams, 1969, p.6.  Holotype: Valensi, 1953, pl.12, fig.6.  NOW Dapsilidinium?.  Originally Micrhystridium (Appendix A), subsequently Hystrichosphaeridium, thirdly Polysphaeridium?, fourthly (and now) Dapsilidinium?.  Questionable assignment: Davey and Williams (1969, p.6).  This combination, as a questionable assignment, was not validly published in Davey and Williams (1966b, p.95), since these authors did not fully reference the basionym.  Age: Middle Jurassic.
