Diagnosis Test biconvex, lenticular, with prominent radial spines, thick-walled embryo consists of spherical proloculus and one and a half whorls of trochospirally arranged chambers interconnected by two to three stolons each and communicate with the spiral canal system on the ventral side by a single small radial canal, four to eight large spines arise from the spiral juvenarium and continue to enlarge with growth, anastomosing spine canals connected by radial canals to the central spiral canal, spiral juvenile followed by successive growth steps of numerous domelike lateral chamberlets in a loose network over the test, chamberlets of successive networks alternate in position and communicate through oblique multiple stolons, but chamberlets also are aligned in series that radiate from the center, those adjacent to the spines may have connections to the spine canals and those of the final series have small basal apertures on all sides of the chamberlets, solid pillars inserted between the vertical rows of chamberlets and appear at the surface as imperforate pustules; wall calcareous, coarsely perforate.
