"oligospinosum" (Eisenack, 1934, p.64-65, pl.4, figs.15-18 ex Eisenack, 1938a, p.12) Downie and Sarjeant, 1965, p.152.  Holotype: Eisenack, 1934, pl.4, fig.18, lost according to Eisenack et al. (1973, p.494).  NOW Estiastra? oligospinosa (Appendix A).  Originally Ovum hispidum subsp. oligospinosum (name not validly published, Appendix A), subsequently Hystrichosphaeridium oligospinosum, thirdly Pulvinosphaeridium oligospinosum (Appendix A), fourthly Veryhachium oligospinosum, fifthly Goniosphaeridium oligospinosum (Appendix A), sixthly (and now) Estiastra? oligospinosa (Appendix A).  This combination was not validly published in Deunff (1954b, p.306), since that author did not fully reference the basionym or clearly use the name Veryhachium oligospinosum.  It was not validly published in Downie and Sarjeant (1963, p.94) and Eisenack (1963b, p.209), since these authors did not fully reference the basionym.  Age: Silurian (erratic).
