TL;DR: One form of Circumpolles described originates in the Airel quarry (France), which also yielded Classopollis harrisii Muir van Konijnenburg-van Cittert and corresponds to Classoidites glandis Amerom, while the other three forms come from a sample of Triassic at Les Vans (France) in which the genera Circulina and Classopolls are found together.
