In the Sea of Japan it inhabits thehigh sublittoral zone of the western coast of Japan.3. Genus Cilunculus Loman, 1908Type species: Lecythorhynchus armatus Böhm, 1879.Trunk elongated, well segmented. Anterior margin of cephalic segment coverspeak-like (or hood-like) insertions of chelifores. Ocular tubercle tall, thin, situatednear frontal margin. Proboscis oval, with flat apex. Chelifore 2–3-segmented; adultfingers of chela reduced. Oviger 10-segmented, with extremely long segment 2;terminal claw absent. Femur in males provided with thin cement gland duct, pointeddistally, often longer than femur’s diameter. Auxiliary claws present.One species of this genus has been recorded in the Sea of Japan.1. Cilunculus armatus (Böhm, 1879)(Pl. XV, figs. 8–13)Böhm, 1879b: 141 (Lecythorhynchus armatus); Schimkewitsch, 1909: 4, fig. 2(Ammothea armata); Nakamura & Child, 1983: 33; Nakamura, 1987: 33–34, pls. 30, 39(Cilunculus armatus).Description. Trunk elongated, segmented; each of first 3 segments dorsodistallybear one tall tubercle with several setae. Anterior part of cephalic segment covers 1stlateral processes hood-like. Lateral angles of anterior "hood" bear tubercles with setae,lower than dorsal tubercles. Lateral processes long, separated by less their owndiameters. Several small tubercles with rather long spines situated on distal margins oflateral processes. Ocular tubercle situated near anterior margin of cephalic segment,conical, with acutely pointed top, as tall as distal tubercles on trunk segments; no eyes.Proboscis large, elongated, oval, with flat apex, as long as trunk. Abdomen cylindrical,slightly swollen distally, convex dorsally, armed with strong spines on tubercles,reaches middle of 2nd coxae of 4th legs. Chelifore small; scape 2-segmented; segment1 short; segment 2 twice longer, bearing tubercles with spines on dorsal and lateralsides; chela small, globular, without fingers. Palp 9-segmented; segment 2 longest, 9times as long as its own diameter; segment 4 about 1/3 shorter than segment 2, withseveral setae dorsally; 5 distal segments almost equal in length, ventrally armed withdense setae twice or more longer than diameters of these segments. Oviger 10-segmented; segment 2 longest, straight; male segments 6 and 7 covered with longsetae distally; segments 8 and 9 bear one compound spine each; segment 10 bears 2compound spines. Compound spines thin, long, with numerous blunt lateral teeth.Legs armed with numerous setae; coxa 1 bears long setae laterally and dorsally; coxa2 twice in males and 1.5 times in females longer than coxa 1; femur, tibiae 1 and 2subequal; cement gland duct thin, long, situated on distal third of femur at angle tofemur’s end; propodus slender, noticeably curved, about 1.5 times shorter than tibia 2,117
