mensula Wetzel, 1933b, p.49-50, pl.4, fig.32 ex Downie and Sarjeant, 1965, p.151. Holotype: Wetzel, 1933b, pl.4, fig.32. Originally Hystrichosphaera (name not validly published), subsequently Hystrichosphaeridium (name not validly published), thirdly (and now) Veryhachium. This combination was not validly published in Downie and Sarjeant (1963, p.94), since these authors did not reference the "basionym". The name Hystrichosphaera mensula was not validly published in Wetzel (1933b) since the generic name Hystrichosphaera was not validly published until 1937. N.I.A. Age: Late Cretaceous.
