franconium (Sannemann, 1955, p.328, pl.3, fig.1; pl.5, figs.1–2) Downie and Sarjeant, 1965, p.90.  Holotype: Sannemann, 1955, pl.5, fig.1.  Originally Hystrichosphaeridium, subsequently (and now) Baltisphaeridium.  This combination was not validly published in Downie and Sarjeant (1963, p.90), since these authors did not fully reference the basionym.  Age: Devonian (late Givetian).
