Le Coze

Pb of priority + G. mariei Banner & Blow, 1960 is a primary junior homonym of G. mariai (emend. mariei) Gandolfi, 1955

G. quadrata should have the priority

I will ask Brian Huber to look at that (but he is away now for a copule of months). Jeremy

Brian Huber

Globotruncana quadrata moved from under mariei and now considered a junior synonym of Globotruncana linneiana
