St. WS 85. 25. iii. 27. 8 miles S 66° E of Lively Island, East Falkland Islands, from 52" 09' S, 58° 14' W to S2' 08' S, 58° 09' W, 79 m.; S. Sh. Commercial otter trawl: i ?. Description. Trunk compact; lateral processes in contact, 1-3 each with an anterior and a posterior spinose process, 4 with an anterior one only (Fig. 69). Cephalic segment distinctly separated off by a suture from the succeeding segments, which are all com- pletely fused. Two acute antero-lateral spinose processes on cephalon; ocular tubercle high, tubular, situated mid-way between these on the anterior border of cephalon. Eyes large, sub-terminal. Two high, slender, spinose projections on mid-dorsal surface, between cephalic suture and abdomen (Fig. 69).. Fig. 69. Nymphopsis denticulata, Holotype. Lateral view of body with chelophore: x 30. Proboscis slightly longer than trunk, ovate, tapering anteriorly to a blunt point (Fig. 69). Abdomen, long, slender, sub-cylindrical, elevated in distal half and reaching a little beyond the distal end of the second coxa; two small spinose projections on proximal half (Fig. 69). Chelophore approximately half as long as proboscis. Scape of almost uniform diameter throughout and consisting of a single segment; a short, stout, spinose process on the mid-dorsal surface, a bifurcated process at the inner, and two smaller spines at the outer distal angle (Fig. 70 a, lateral aspect). Chela small and imperfect. Palp as represented in Fig. 70 b, nine-jointed and longer than proboscis. Oviger ten-jointed, with one or two denticulate spines on the four terminal segments as in some species of Achelia (Fig. 70 c: cf. Fig. 59 a, c); terminal claw absent. Walking leg. The second walking leg, which was already detached from the specimen, is represented in Fig. 70 d and e
