A. viridintestinalis is a littoral and high sublittoral species. It is distributed in theeastern part of the Pacific Ocean from the Californian shore up to Panama. It has alsobeen found in the southern part of the Sea of Japan near Dagelet Island and HornetIsland.*Anoplodactylus carnatus Nakamura & Child, 1983(Pl. XXI, figs. 7–10)Nakamura & Child, 1983: 42–44, fig. 14; Nakamura, 1994: 15.Anoplodactylus carnatus provisionally is endemic from the waters surroundingthe Japanese Islands. It was found near the eastern coast of Japan in Suruga andSagami Bays at depths of 7–15 m, and in the Sea of Japan in the littoral zone ofToyama Bay.*V. Family COLOSSENDEIDAE Hoek, 1881Trunk segmented or unsegmented, sometimes with traces of articulation lines.Lateral processes separated by intervals. Neck absent. Ocular tubercle situatedanteriorly on cephalic segment. Adults usually lack chelifores; in some juveniles 3-segmented chelifores present (adults of some deep-water species have similar 3-segmented chelifores (Turpaeva, 1989). Palp 8–9-segmented. Oviger 10-segmented,with terminal claw and compound spines, placed in several rows on 4 distal segments.Legs long; propodus lacks heel. Coxae 2 of all legs bear genital pores in both malesand females.Two genera are represented in the Sea of Japan. They presumably occur in theRussian waters, too.KEY TO THE GENERA OF THE FAMILY COLOSSENDEIDAE1(2). Trunk unsegmented, eyes not developed ........................... *Colossendeis (p. 127)2(1). Trunk segmented, eyes large, pigmented ............................. *Hedgpethia (p. 128)*Genus Colossendeis Jarzynsky, 1870Type species: Colossendeis borealis Jarzynsky, 1870.Trunk unsegmented; cephalic segment slightly larger than next segment.Proboscis robust, usually straight, but in some species tapers toward end and may benoticeably longer than trunk. Palp 8–9-segmented. Oviger with false chela, or, moreoften, has normal shape. Four pairs of legs present; tarsus and propodus equal inlength, or tarsus longer; no cement glands on femur; no auxiliary claws.Hedgpeth (1949) recorded two species of the genus Colossendeis in the waterssurrounding Japan, namely, C. nasuta Hedgpeth and C. macerrima Wilson. Hedgpetherroneously named the latter species C. japonica Hoek. Both species were found nearthe south-western coast of Kyushu Island at 700–800 m depths. Assuming theoccurrence of these two species in the deep waters of the Sea of Japan, a key for theiridentification is given below.127
