Description
Test triserial and triangular throughout, gradually enlarging; wall calcareous, coarsely perforate; aperture basal in final chamber, with internal tooth plate. [Reussella is restricted here to include only sharply angular species, commonly with carinate or spinose angles, coarsely perforate wall, and complex tooth plate. Upper Cretaceous species that have been previously referred to Reussella are here regarded as belonging to Pyramidina, differing in their less angular margins, finely perforate walls, and simpler tooth plate.]
