staurasteroides (Deflandre, 1945a, p.25–26, pl.2, figs.7–9) Downie and Sarjeant, 1965, p.152.  Emendation: Stancliffe and Sarjeant, 1994, p.234, as Veryhachium staurasteroides.  Holotype: Deflandre, 1945a, pl.2, fig.7.  Originally Hystrichosphaeridium, subsequently (and now) Veryhachium.  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.  Age: Middle Silurian.
