Milne Edwards, 1837), E. pusiolus (Kröyer, 1841), E. suckleyi (Stimpson, 1864), Heptacarpus brevirostris (Dana, 1852), H. herdmani (Walker, 1898), Hippolyte varians Leach, 1814, Lebbeus groenlandicus (Fabricius, 1775), Lebbeus polaris (Sabine, 1824), L. cf. spinirostris (Kobyakova, 1936), Spirontocaris arcuata Rathbun, 1902, S. holmesi Holthuis, 1947, S. lamellicornis (Dana, 1852), S. lilljeborgii (Danielssen, 1859), S. murdochi Rathbun, 1902, S. phippsii (Kröyer, 1841), S. spinus (Sowerby, 1805) (Hippolytidae) and Pandalopsis aleutica Rathbun, 1902, P. dispar Rathbun, 1902, Pandalus borealis Kröyer, 1838, P. goniurus Stimpson,1860, P. jordani Rathbun, 1902, P. montagui Leach, 1814 (Pandalidae), from Greenland, Iceland, Ireland, England, Denmark, Norway, Arctic Ocean, White Sea, Barents Sea, Sea of Okhotsk, Bering Sea, Japan, Korea, Yellow Sea, Taiwan, Kodiak, Alaska to Puget Sound, Washington, Ellsmere Island, Baffin Bay, Gulf of St. Lawrence, Nova Scotia, Maine to Cape Cod Bay, Massachusetts, 60 m (Yellow Sea), 506–680 m (Taiwan) (most other depths not recorded). REMARKS: Bopyroides hippolytes has been described many times in detail (see Markham, 1985a, for a more complete synonymy and discussion). The synonymy list provided here includes only select references published after Markham (1985a). All hosts are in Hippolytidae and Pandalidae. Boyko (2004) recorded this species from Chinese waters infesting Lebbeus cf. spinirostris (Kobjakova) off Taiwan. The present specimens conform well to previous descriptions of this species, but the host and locality are new records. Birulia kishinouyei has not previously been reported as hosting any bopyrid.

MATERIAL EXAMINED: Infesting Hippolyte sp. (Hippolytidae), 1 ♀ (CIEHI 560901), 1 ♂ (CIEHI 560902), Sea Island, Dalian City, Jiangsu Province, 123 ° 15′E, 39 ° 00′N, 27 September 1956. DESCRIPTION: Female (CIEHI560901): Length 4.86 mm, maximal width 3.60 mm, head length 0.84 mm, head width 1.28 mm, sinistrally distorted 36 ° (fig. 12A, B). Head ovate, anterior edge bilobate, frontal lamina present, eyes absent (fig. 12A). Maxilliped (fig. 12C) with setose, articulated palp, inner edge fringes with setae. Barbula (fig. 12D) with two pairs of sharp, elongate falcate lateral projections on each side. Pereon broadest across third pereomere (fig. 12A). Narrow rudimentary coxal plates on first four pereomeres of both sides. Lateral margin of pereomeres 5–7 indented (fig. 12A). Brood pouch completely open (fig. 12B). Oo‐ stegite 1 (fig. 12E, F) with two equally long articles, internal ridge almost smooth, posterolateral point blunt and directed laterally; fifth oostegite longest. Pereopods with sub‐ equal size and structure (fig. 12G), blunt dactyli, bases with carinae. Pleon of five pleomeres, fused medially. Pleopods and uropods lacking. DESCRIPTION: Male (CIEHI560902): Length 1.87 mm, maximal width (across pereon 5) 0.58 mm, head width 0.34 mm, pleonal length 0.51 mm. All pereon segments distinct, pleomeres fused (fig. 12H, I). Head a flattened ellipse (fig. 12H), eyes in posterolateral corners (fig. 12H). Antennule of three articles, antenna of five articles, terminally setose, extending beyond margins of head (fig. 12I). Pereomeres subequal in width, lacking midventral projections (fig. 12I). Pereopods with subequal size and structure (fig. 12I). Pleon completely fused, pleopods and uropods lacking (fig. 12I). HOSTS AND LOCALITIES: Infesting Heptacarpus geniculatus (Stimpson, 1860), Heptacarpus pandaloides (Stimpson, 1860), Hippolyte sp., Spirontocaris ochotensis (Brandt, 1851) (Hippolytidae), Japan and Jiangsu Province, China. REMARKS: Shiino (1937a) recorded Bopy ‐ roides hippolytes infesting three Spirontocaris spp. from Japan, but this material was considered as belonging to B . shiinoi by Rybakov and Avdeev (1991), which was described from a more northerly locality in the Sea of Japan and from different hippolytid hosts. Rybakov and Avdeev (1991) noted that the most obvious difference between B . hippolytes and B . shiinoi is in the fusion of the terminal pleomeres. The present female does not have tubercular pleopods but does have fusion of the last two pleomeres, suggesting that it is conspecific with B . shiinoi . The host of the present specimens must be new, as no species of Hippolyte was previously known as a host for B . shiinoi , but this host specimen is not identifiable beyond the genus level.
