Terebratulina japonica (Sowerby, 1846) (Fig. 1A, B) 2006 Terebratulina japonica (Sowerby) —Bitner, p. 22–23, figs.3, 4A–G (cum syn.). 2008 Terebratulina japonica (Sowerby) —Bitner, p. 433–434, fig. 7A–D. 2010 Terebratulina japonica (Sowerby) —Zezina, p. 1185. Material examined. DongSha 2014 cruise, stn DW 4125, 21°02’N, 116°28’E, depth 305–306 m, four specimens. Remarks. In outline and ornamentation the specimens resemble Terebratulina japonica, a species known from off Japan (Hatai 1940, Logan 2007) and Fiji (Bitner 2006, 2008). Terebratulina japonica is characterized by a rounded to oval shell ornamented by numerous fine but distinct ribs. Two other Terebratulina species known from this region, T. photina and T. hataiana, are larger than T. japonica, the first having a nearly smooth surface, the second fine, flat costellae (Dall 1920, Cooper 1973c).
