Material examined. Korea, East Sea , station E3 (37°55 ʹ 4.816 ʺ N, 128°51 ʹ 11.786 ʺ E), 20 May 2016, by Van Veen Grab, collected by Raehyuk Jeong and Jisu Yeom. NIBR ID: NIBRPR0000107246 .

Diagnosis. Wall calcareous, porcelaneous. Test ovate, inflated, chamber arrangement biloculine, involute at later portion. Suture depressed. Aperture terminal, wide, with a broad tooth.

Remarks. Biloculine and strongly biconvex test and an oval shaped aperture with broad, rounded tooth are the typical features of P. inornata . Our specimen had a slightly more elongated test than specimens reported from New Caledonia ( Debenay, 2013) and Jeju island ( Kim et al., 2016), but mostly resembles the specimen reported by Cushman in 1921 from the Philippines and the type specimen reported from Austria ( Ellis & Messina, 1940).

Distribution. Korea, China, Japan, New Caledonia, New Zealand, Sahul Shelf, Gulf of Mexico, North Atlantic Ocean, Bay of Biscay ( France), Mediterranean Sea.
