Material examined. MBC-A 022284; MBC-A 022285; MBC-A077893; MBC-A077903; MBC-A077899; MBC- A077900; MBC-A077896; MBC-A077898; MBC-A077897; MBC-A077895; MBC-A077902; MBC-A077894; MBC-A077901.

Identification. Test flat, raised center. Apical disc subcentral. Peristome also subcentrally located; round periproct positioned between peristome and posterior edge. Petals narrow, flexed, sometimes closed, in other cases opened. Spines short. Yellow or brownish in color.

Global maximum size. Maximum length 73 mm.

Global distribution. East coast region of South Africa, East Africa to Malayan region, Philippines, southern Japan and Hawaii; at 50–645 m depth ( Mortensen 1948d; Schultz 2009).
