Description

13. Cassidulina limbata Cushman & Hughes, 1925

(Plate 2. 7a-c)

Cassidulina limbata Cushman & Hughes, 1925, p. 12, pl. 2, fig. 2a-c (cited from Ellis & Messina, 1940).

Material examined. Korea, East Sea, station E8 (37°23 ʹ 55.665 ʺ N, 129°14 ʹ 57.671 ʺ E), 21 May 2016, Van Veen Grab, by Raehyuk Jeong and Jisu Yeom. NIBR ID: NIBRPR0000107248.

Diagnosis. Test nearly circular to lenticular in side view with slightly projecting final chamber. Peripheral margin carinate and slight lobulate. Chambers distinct, biserially arranged and clear umbonal boss in the center. Sutures distinct, curved, weakly limbate. Wall calcareous, hyaline, and perforate. Aperture close to inner margin of the final chamber, narrow elongate, parallel to periphery.

Remark. This specimen is superficially similar to C. translucens Cushman & Hughes, 1925, but the umbilical boss, carinate width, and the last chamber shape are different. There are 76 extant Cassidulina species worldide reported, and ten species have been reported from Korea.

Distribution. Korea, California.
