Veryhachium lairdii Appendix A

"lairdii" Deflandre, 1946c, card 1112 ex Loeblich Jr., 1970, p.742.  Holotype: Deunff, 1959, pl.8, fig.75, designated by Loeblich Jr. (1970, p.742).  Originally Hystrichosphaeridium (name not validly published), subsequently Veryhachium.  Taxonomic senior synonym: Veryhachium valiente Cramer, 1964, an acritarch species, according to Martin (1969, p.95), who believed Veryhachium lairdii to be the senior name.  Taxonomic junior synonym: Veryhachium bromidense Loeblich Jr., 1970, an acritarch species, according to Turner (1984, p.142).  The name Hystrichosphaeridium lairdii was not validly published in Deflandre (1946c) since that author did not provide a description.  Age: Middle Silurian.
