"malleoferum" (White, 1842, p.37, pl.4, div.3, fig.7) Downie and Sarjeant, 1965, p.92. Holotype: White, 1842, pl.4, div.3, fig.7; Sarjeant, 1991, fig.4.6. NOW Achomosphaera?. Originally Xanthidium (Appendix A), subsequently Baltisphaeridium, thirdly (and now) Achomosphaera?, fourthly Hystrichosphaeridium (combination not validly published). This combination was not validly published in Downie and Sarjeant (1963, p.91), since these authors did not fully reference the basionym. Age: Late Cretaceous.
