Operculinoides Hanzawa as understood now consists of three distinct groups of forms typically represented by (a) Nummulites willcoxi Heilprin, (b) Operculina ocalana Cushman, and (c) O. bermudezi D. K. Palmer. It is shown that (a) can justifiably come under Nummulites, (b) may be regarded as involute Operculina, and for (c) there is Caudri's genus Ranikothalia which is based on valid grounds.
