The material assigned by Totton (1930) to Oswaldella antarctica (Jaderholm, 1904) and O. bifurca (Hartlaub, 1904) has been re-examined and redescribed. This material shows such important differences with Hartlaub's and Jaderholm's species and the remaining species of Oswaldella that they are here considered as two new species: O. terranovae spec. nov. and O. tottoni spec. nov., respectively.Descriptors: OSWALDELLA TERRANOVAE new species; OSWALDELLA TOTTONI new speciesfigs 1-2.
