"Polysphaeridium? majus" (Lejeune-Carpentier, 1940, p.B220-B221; text-fig.13) Davey and Williams, 1969, p.6.

EMENDATION: Lejeune-Carpentier and Sarjeant, 1981, p.12, as Amphorosphaeridium majus.

TYPE: Holotype: Lejeune-Carpentier, 1940, text-fig.13; Lejeune-Carpentier and Sarjeant, 1981, pl.2, figs.6-7; text-fig.7.

HISTORY: NOW: Amphorosphaeridium. Originally Hystrichosphaeridium, subsequently Polysphaeridium?, thirdly Cordosphaeridium, fourthly Dapsilidinium? (combination not validly published), fifthly (and now) Amphorosphaeridium. Questionable assignment: Davey and Williams (1969, p.6).

COMMENTS: This combination, as a questionable assignment, was not validly published in Davey and Williams (1966b, p.95), since these authors did not fully reference the basionym.

AGE: Senonian.
