Remarks. The first author ( Hanagata, 2004) erroneously identified this as the variation which has a bulla-like cover closing the umbilicus under the name of Candeina nitida . Belford (1962), Huang (1968, pl. 11, fig. 10), Kadar (1977), and Loeblich and Tappan (1994, pl. 193, figs. 8—10) illustrated variants with such bulla-like covers.

Occurrence. Common in the Minebari and Yonahama formations.
