| | | | | | | Ref.: | | | Ummerkutty, 1963 (p.19, figs.F,M); Humes & Smith, 1974 (p.130, Rem.) |  issued from : A.N.P. Ummerkutty in Bull. Dep. mar. Biol. Oceanogr., 1963, 1. [Pl.I, Figs.10-18]. Female: 10, habitus (dorsal); 12, Mxp; 13, Md (mandibular palp); 14, P1; 15, PP3; 18, urosome and posterior part of prosome (lateral). Nota: Ratio Prpsome: Urosome as 72:28. Head and 1st pediger segment separate, 4th and 5th separated. Urosome 4-segmented. Genital segment symmetrical. Relative lengths of urosomal segments and caudal rami 44.3:17.1:15.7: 5.8: 17.1 = 100. A1 26-segmented, reaching to posterior end of prosome. Male: 11, right A1; 16, P5; 17, right P5 (terminal part of exopod, enlarged). Nota: Right A1 geniculate, 23-segmented; the point of geniculation between 2th and 21th segments; posterior margin of the thirteenth segment is highly shortened, almost to a point, so that the segment is triangular; the 2ith segment carries a row of spinules arranged along its length towards anterior face.
