Description: Large with gently convex sides, triserial stage bluntly angular; biserial stage distinct and well rounded.
Distribution: Bortonian to Otaian.
Comment: Finlay, and subsequent workers have regarded G. reussi as a descendant of G. proreussi but a recent discovery of a good reussi population in the lower Bortonian in North Canterbury has shown this not to be so. Forms like G. reussi with strongly concave sides in the Waitakian and Otaian, named Gaudryina anachrons by Finlay, are probably ecological variants of reussi.
