( Plate 2. 1 a-c)

Ammobaculites cylindricus Cushman, 1910 View in CoL , pl. 441, figs. 15-16 (cited from Jones, 1994).

Material examined. Korea, East Sea , station E1 (38°24 ʹ 29.004 ʺ N, 128°30 ʹ 21.88 ʺ E), 19 May 2016, by Van Veen Grab, collected by Raehyuk Jeong and Jisu Yeom. NIBR ID: NIBRPR0000107249 GoogleMaps .

Diagnosis. Test free, large, elongated, cylindrical and uniserial with a planispiral early portion. Wall coarsely agglutinated. Suture depressed but not distinct due to agglutinated particles. Aperture rounded and terminal.

Remarks. This specimen is similar to A. cylindricus ( Jones, 1994, plate 33 fig. 6) in having the long, straight cylindrical outline of test. According to Cushman (1921), this species differs from the ordinary form of A. calcareus by having a cylindrical shape, and differs from A. agglutinans (d’Orbigny, 1846) in the greater proportion of involute coiling portion.

Distribution. Korea, Philippines, North Atlantic Ocean.
