Amphistegina lessonii (several species represented see note)
Description Amphistegina lessonii sensu Jones, R.W. 1994. The Challenger Foraminifera. Image source: Brady, H.B. (1884) Pl. 111
Note: Hallock Muller (2019) pers. comm.: " 2 is A. bicirculata; 5 is A. lessonii, and probably also 6; 7 is A. gibbosa, and probably also 4. Larsen (1976) called both 1 and 2 A. bicirculata, but 2 is nearly identical to his figures. I am not sure what 1 is, probably a younger A. radiata (look at the number of chambers compared to 2) ."
