Diagnosis Test flattened, low trochospiral to nearly planispiral coil of two to three whorls, eight to twelve chambers in the final whorl, sutures slightly depressed, chambers on umbilical side separated by deeply incised sutures with granulose to spinose borders, the umbilical end of the wide sutural interlocular space covered by a backward extension from the lip of the final chamber, liplike extensions of successive chambers radiating from the umbilicus that is filled with a central pillar, simple spiral canal around the umbilical plug is connected to the hooked umbilical extensions from the chambers, periphery with imperforate keel interrupted by deep sutural incisions; wall calcareous, perforate, optically radial, surface of spiral side smooth between the numerous inflational knobs, pustules, and ridges that may obscure the sutures or the sutural incisions may be bordered by narrow ridges, three large solid spines arise as extensions from the imperforate keel of the first whorl in megalospheric specimens and from the third whorl of the microspheric generation and are subsequently enlarged by lamellar growth as new chambers and whorls are added; aperture a vertically aligned and nearly equatorial ovate opening at the base of the apertural face, a small hooked foraminal plate present at the umbilical margin of the foramen.
