 Issued from : G.O. Sars in Résult. Camp. Scient. Prince Albert I, 69, pls.1-127 (1924). [Pl.XLVI, figs.5-22]. Female: 15, habitus (dorsal); 16, idem (lateral left side); 17, forehead (lateral); 18, rostrum; 19, P1; 20, P2; 21, P3; 22, P5.

 issued from : R.B.S. Sewell in The John Murray Expedition, 1933-34, Scientific Reports, VIII (1), 1947. [p.153, Fig.39, A]. Female (from G. of Oman): A, genital segment and 2nd urosomal segment (ventral). Nota: The proportional lengths of the cephalothorax and abdomen as 77 to 22. The proportional lengths of the various segments of the body (cephalon to caudal rami) as 350:186:106:80:35:20:95:44:34:24:26 = 1000. Head and 1st pediger segment almost completely fused, but a faint line of fusion can be traced across the dorsal region, similarly 4th and 5th almost completely fused. Caudal rami as broad as long and hairy on their inner aspects. A1 24-segmented (segments 8-9 fused) reaches back to the anal segment. The genital aperture presents certain differences, as will be seen from a comparison with L. frontalis.

 issue from : O. Tanaka in Publ. Seto Mar. Biol. Lab., 1961, IX (1). [p153, Fig.111]. Female (from Suruga Bay): a, habitus (dorsal); b, forehead (lateral); c, last thoracic segment and urosome (lateral, left side); d, P1; e, P2; f, P5. - Cephalothorax about 4.16-4.26 times the abdomen length (5.2 : 1.25 or 81 to 19). - Head and 1st pedigerous segment fused, 4th and 5th pediger segments fused. - Head without crest. - Forehead obtusely rounded in lateral aspect. - Posterolateral corners of the last thoracic segment narrowly rounded. - Rostrum strong, short and bifurcate. - Urosome 4-segmented; abdominal segments and caudal rami in yje proportional lengths 39 : 18 : 14 : 18 : 11 = 100. - Genital segment about as long as wide. - Abdominal segments 1 to 3 fringed with fine teeth on distal margin. - Caudal rami longer than wide (20: 18). - A1 24-segmented, exceeds the distal end of the caudal rami by terminal 1 segment. - A2 exopod about as long as endopod; distal segment of exopod short. - Mouthparts and swimming legs as those of Lophothrix frontalis Giesbrecht. - P5 3-segmented, resembles that of L. frontalis; 1st and 2nd segments furnished coarsely with small spines on the anterior surface.
