"echinoides" (Maier, 1959, p.318–319, pl.32, figs.5–6) Downie and Sarjeant, 1965, p.90. Holotype: Maier, 1959, pl.32, fig.6. Originally Hystrichosphaeridium, subsequently Baltisphaeridium, thirdly Cleistosphaeridium. Taxonomic senior synonym: Xanthidium (now Spiniferites) ramosum, according to Sarjeant (1983, p.91–92). This combination was not validly published in Downie and Sarjeant (1963, p.90), since these authors did not fully reference the basionym. Age: middle Oligocene–middle Miocene.
