Diagnosis Test elongate, stout, circular in section, long triserial stage with depressed and oblique sutures, later chambers more loosely triserial, final one or two tending to become uniserial; wall calcareous, perforate, with narrow, elevated, and widely spaced longitudinal costae that commonly are continuous across the sutures but tend to die out early on the final chamber; aperture rounded, terminal, on a short and smooth cylindrical neck.
