Description
Test spherical, ellipsoidal, fusiform, or cylindrical; septula alternating in adjacent chambers, with pre- and post septal passages; coiling of first whorls irregular in microspheric form of all species bu t regular in megalospheric form of most species; 2 rows of apertures alternating in position; may show enormous basal thickening in several internal whorls (e.g., "Flosculina") or secondary apertures and chamberlets irregularly distributed in axial zone and mostly not connected with preseptal passages (e.g., "Eoalveolinella"). [Many species are important as rock-builders.]
