| Summary: | Henricia pacifica Hayashi, 1940 Figures 10 A–F, 12I Henricia pacifica Hayashi, 1940: 152: pl. 9, figs 7–10.— Djakonov, 1958: 301; 1961: 16.— Hayashi, 1973: 79, pl. 13, fig. 2. Material examined. East China Sea. One (R 36– 19 mm, r 4.8 mm, R: r 7.5–4.0), MBM175692, CN V580B-23, Stn. 13, 30°30ʹN,128°00ʹE, 365-395m, muddy sand, AT, coll. ZHANG, 1 Jul 1978;Two (R 31– 29 mm, r 5.2 mm, R: r 6.0–5.6; R 17– 14 mm, r 3.5 mm, R: r 4.9–4.0), MBM175701, CN V469B-79, Stn. V-11, 27 °30ʹN,126°00ʹE, 162m, fine sand, AT, coll. WU, 10 Oct 1975; One (R 51– 47 mm, r 7.0 mm, R: r 7.3–6.7), MBM176346, CN KY10B-82, Stn. Z -4, 28°40ʹN, 128°40ʹE, 1115m, soft mud, AT, 4 Aug 1981. Distribution. East China Sea, Japan, and Sakhalin, 50–1115 m. Remarks. This species is closely related to Henricia arcystata Fisher, but differs in each adambulacral plate bearing more numerous subadambulacral spines (on the plate surface) and a single furrow spine, not three furrow spines in a vertical series. Our specimens do not possess a short series of the secondary ventrolateral plate at the arm base. In addition, the present specimen extends the depth of the species to 1115 meters.
