Planche 1 issued from : O. Tanaka & M. Omori in Publs Seto Mar. Biol. Lab., 1974, XXI (3/4). [p.228, Fig.16].
Female: a, forehead (lateral); b, last thoracic segment and urosome (lateral left side); c, idem (dorsal); d, Md; e, Mx1; f, Mx2; g, Mxp; h, P1; i, exopod of P2; j, P5.
Nota: The urosome segments and furca are in the proportional lengths as 41:11:25:23 = 100. Prosome and urosome are in the proportional lengths as 77:23 A1 reaches to the tip of the furca.
The specimen from the Izu region differs in some details from Sars's (1925) and Sewell's (1932) descriptions. A specimen from the Gulf of Guinea , provided by Vervoort, has 26 setae on the 2nd basal segment and the endopod of Mx2, the two basal segments of Mxp have 0, 0, 2, 2 and 2 setae.

Planche 2 issued from : O. Tanaka & M. Omori in Publs Seto Mar. Biol. Lab., 1974, XXI (3/4). [p.198, Fig.1,l].
Female: l, mandibular teeth.

Female: 1, habitus (dorsal); 2, idem (lateral left side); 3, forehead (lateral); 4, rostral prominence; 5, A2; 6, Md; 7, Mx1; 8, Mx2; 9, Mxp; 10, P1; 11, P2; 12, P3; 13, P5; 14, posterior part of urosome.

Planche 4 Issued from : R.B.S. Sewell in Mem. Indian Mus., 1932, X (continued). [p.324, Fig.106].
Female (from off W Sri Lanka): a, habitus (dorsal); b, urosome (dorsal); c, Md; d, Mx1; e, Mxp; f, P1; g, P2; h, P5.

Planche 5 issued from : S. Ali-Khan & J. Ali-Khan in Crustaceana, 1984, 47 (3). [p;306, Figs.13-20].
Female (from 24°09'N, 64°27'E): 13, forehead (ventral); 14, Md (mandibular palp); 15, Md (biting edge); 16, Mx1; 17, Mx2; 18, terminal portion of seta (enlarged; 19, P1; 20, P5.

Nota: Exopod of A2 about 1/3 of the length of the endopod as in Sars (1925), while Sewell (1932) stated that it resches halfway. There is incomplete fusion of only segments 7 and 8 of the exopod (as in Sars' specimen). Internal lobe 1 of Mx1 with 3 + 3 setae (Sars shows 3 + 2, and Sewell 3+ 1); lobes 2 and 3 absent; external lobe show 3 setae (as in Sewell's figure, but Sars depicted 4). The greatest difference has been noted in the total number of setae on basipod 2 and endopod of Mx2 together: 22 (Sewell's figure shows 35 and Sars's 15).

Planche 6 issued from : O. Tanaka & M. Omori in Publs Seto Mar. Biol. Lab., 1974, XXI (3/4). [p.228, Fig.16].
Female (Canarias Islands): a, forehead (lateral); b, last thoracic segment and urosome (lateral left side); c, idem (dorsal); d, Md; e, Mx1; f, Mx2; g, Mxp; h, P1; i, exopod of P2; j, P5.
Nota: The urosome segments and furca are in the proportional lengths as 41:11:25:23 = 100. Prosome and urosome are in the proportional lengths as 77:23 A1 reaches to the tip of the furca.

Planche 7 issued from : O. Tanaka & M. Omori in Publs Seto Mar. Biol. Lab., 1974, XXI (3/4). [p.228, Fig.16].
Female:Number of setae on the various lobes of Mx2.
Nota: In Mx2 of some of these females lobe 6 and endopod cannot be distinguished, and in one specimen there is some variation between the left and right side.

Planche 8 issued from : H.S.J. Roe in Bull. British Mus. (Natural History) Zool., London, 1975, 28 (7). [p.352, Fig.26, i-q].
Female (from Cape Verde Is. - Canarias Is.): i, habitus (dorsal); j, forehead (lateral); k, last thoracic segment and urosome (lateral, roight side); l, A2; m, Md (mandibular palp); n, Md (mandible blade); o, Mx1; p, Mx2; q, P1.
