DIAGNOSIS. —“The single spherical shell is spongy; a basal layer is not present. Three to four apophyses arise from every ray of an internal spicule at one to several levels. They or their branches join directly, or through one or more intervening bars, to neighboring apophyses and form a complex network structure (N-frame). The N-frame is represented by a subcircular to sub rhombohedral frame (R-frame). The internal spicule with a median bar is six-rayed.” ( Won 1997b: 383).
