Diagnosis
Excavating sponges of alpha growth form with large tylostyles and generally two types of amphiasters as microscleres: stout, nodulose in the papillae and delicate thin-rayed with terminal branching of the slender rays, in the chambers. The nodulous amphiasters may be absent in some specimens or species (Topsent 1928b; Rützler 1973). On the other hand, a third kind, a very small diplaster has been reported to occur in the papillae (Volz 1939).
