"fimbriatum" (White, 1842, p.36, pl.4, div.3, fig.3) Downie and Sarjeant, 1965, p.91.  Holotype: White, 1842, pl.4, div.3, fig.3; Sarjeant, 1991, fig.4.2.  NOW Filisphaeridium (Appendix A).  Originally Xanthidium (Appendix A), subsequently Hystrichosphaeridium, thirdly Baltisphaeridium, fourthly Comasphaeridium (Appendix A), fifthly (and now) Filisphaeridium (Appendix A).  This combination was not validly published in Sarjeant (1959, p.339) and Downie and Sarjeant (1963, p.91), since these authors did not fully reference the basionym.  Age: Late Cretaceous.
