DISTRIBUTION. — Indonesia, Vanuatu and Fiji. Bathymetric range: earlier known from shells in 130-614 m; Santo specimens collected alive in 20-125 m.

REMARKS

The Santo specimens are indistinguishable from the type material. The rudimentary internal riblets are very variable, i.e. lacking (typically) one or several short rudimentary.
