Not Amphistegina bicirculata (?) see note

Description:

Amphistegina bicirculata sensu Jones, R.W. 1994. The Challenger Foraminifera. Image source: Brady, H.B. (1884) Pl. 111

Note: Hallock Muller (2019) pers. comm. :" I think Plate 111 fig. 2a,b,c are better representations of A. bicirculata than is Plate 111 fig. 1a,b,c, which I suspect is an A. radiata. I suspect that Larsen referred to the wrong set of images."
Plate 111 fig. 1a,b,c was originally included in the synonymies of A. bicirculata by Larsen (1976).
