"Ovum hispidum subsp. ramosum" (Ehrenberg, 1838, pl.1, figs.1-2,5) Eisenack, 1931, p.112.
TYPE: Holotype: not designated. Lectotype: Ehrenberg, 1838, pl.1, fig.5, designated by Davey and Williams (1966a, p.32). STATUS: Combination not validly published: specific name not validly published. HISTORY: NOW: Spiniferites. Originally Xanthidium ramosum (Appendix A), subsequently (and now) Spiniferites ramosus, thirdly Ovum hispidum subsp. ramosum (combination not validly published), fourthly Hystrichosphaera ramosa, fifthly Bion ramosum (Appendix A). SYNONYM(S): Taxonomic junior synonyms: Xanthidium (as Hystrichosphaera) furcatum, according to Davey and Williams (1966a, p.29-33); Galea korykos and Hystrichosphaeridium echinoides, both according to Sarjeant (1983, p.91-92); Areoligera birama, according to Morgenroth (1968, p.550); Geodia? tripunctata, by implication in Sarjeant (1964a, p.175), who considered Geodia? tripunctata to be a taxonomic junior synonym of Hystrichosphaera furcata; Hystrichosphaera (as Spiniferites) bulloidea, according to Harland (1977b, p.101-102) - however, Lentin and Williams (1981, p.259) retained Hystrichosphaera (as Spiniferites) bulloidea; Homotryblium distinctum, according to Jain and Garg (1982, p.69), who considered Homotryblium distinctum to be a taxonomic junior synonym of Spiniferites ramosus subsp. ramosus. MOTILE EQUIVALENT: Gonyaulax spinifera (Claparède and Lachmann, 1859) Diesing, 1866, according to Dodge (1989, p.289). COMMENTS: Downie and Sarjeant (1965, p.174) attributed this combination to Lohmann (1904); however, the combination was apparently not proposed in this latter publication. AGE: Late Cretaceous.
