"cristatum" (Downie, 1958, p.338–339, pl.16, fig.4; text-fig.4f) Downie and Sarjeant, 1965, p.165.  Holotype: Downie, 1958, pl.16, fig.4.  NOW Cymatiogalea (Appendix A).  Originally Hystrichosphaeridium, subsequently Baltisphaeridium, thirdly Priscogalea (Appendix A), fourthly (and now) Cymatiogalea (Appendix A).  Taxonomic junior synonym: Cymatiogalea polygonomorpha Górka, 1967, an acritarch species, according to Rasul (1974, p.56).  Junior homonym: Baltisphaeridium cristatum Grishina in Grishina and Klenina, 1981, an acritarch species.  This combination was not validly published in Eisenack (1958b, p.400), since that author did not fully reference the basionym.  Age: Early Ordovician.
