Diagnosis Test large, discoidal, up to about 17 mm in diameter and 0.5 mm in thickness, early stage planispirally enrolled with rapidly enlarging spire, chambers of almost constant height although rapidly increasing in breadth to become peneropline and finally cyclic, interior subdivided by numerous incomplete vertical septula, aligned in successive chambers, lateral part of chambers becoming very irregular and forming meandriform ridges on the test surface; wall calcareous, imperforate; aperture multiple, of numerous rows of pores on the periphery.
