Description
Test trochospiral, chambers numerous, with axial region of thickened shell material which may show irregular, reticulate texture in sections, septa more or less perpendicular to spiral axis and oblique to axis of test, wall calcareous, microgranular, imperforate, aperture consisting of numerous pores in center of apertural face, secondary intercameral foramina about equidistant from ends of chamber spaces, along central columella and appear there as spiral groove. [Pfenderina differs from Kurunubia in the absence of subepidermal partitions.]
