way) to Greenland, the Spitsbergen, the White Sea, and the Novaya Zemlya (72°23′N,52°41′E); in the Pacific Ocean from the Inland Sea of Japan to the Chukchi Sea(67°44.9′N, 172°47.9′W). In the Sea of Japan it occurs in Peter the Great Bay, off thenorthern coast of Primorye, and in the Tatar Strait.Habitat and breeding. N. bipes is found in depths from 0 to 200–820 m, mostlyto 50 m, on sandy, silty, less commonly on stony and rocky grounds, often among algaeand sea grasses. Females with embryos were recorded in the Sea of Japan Maythrough early September.2. Nebalia hessleri Martin, Vetter & Cash-Clark, 1996(Pl. II, figs. 6–10)Martin et al., 1996: 347–372.Description. Posterior margins of pleonal segments with acutely poined denticles.Dorsal terminal seta on peduncle of first pleopod reaches basal 1/3 of row ofsmall setae on exopod. Fifth and sixth pleopods with 6–8 distolateral spines. Furcalrami 2–2.2 times as long as telson. Length of body up to 15 mm.Distribution. Until recently, this species was known only from the type locality:32°52.5′N, 117°15.5′W (La Jolla, South California). Four specimens of N. hessleriwere collected on July 18, 1975 near the Asian coast, viz.: off the southern coast ofPrimorye, between Zeleny and Bugristy Capes (northeast of Povorotny Cape, about42°50′N, 133°30′E).Habitat. N. hessleri occurs in the high sublittoral zone between 10 and 20 m(type locality at 19 m).Remarks. The specimens found in the Sea of Japan differ from the type specimensin the larger number of distolateral spines on fifth and sixth pleopods (7–8spines in the Sea of Japan specimens versus 6 spines in the type specimens).ReferencesCannon, H.G. 1960.
