Espèce Euaugaptilus elongatus - Planche 1 de figures morphologiquesissued from : O. Tanaka & M. Omori in Publs Seto Mar. Biol. Lab., 1974, XXI (3/4). [p.206, Fig.6].
Female: a, forehead (lateral); b, last thoracic segment and urosome (lateral left side); c, idem (dorsal); d, rostrum (frontal view); e, A2; f, Mx1; g, Mx2; h, P1; i, P5.
Nota: The urosome segments and furca are in the proportional lengths as 45:13:17:23 = 100. Prosome and urosome are in the proportional lengths as 77:23.

Male: j, P5. Nota: The urosome segments and furca are in the proportional lengths as 19:15:14:12:14:26 = 100.

Espèce Euaugaptilus elongatus - Planche 2 de figures morphologiquesissued from : O. Tanaka & M. Omori in Publs Seto Mar. Biol. Lab., 1974, XXI (3/4). [p.198, Fig.1,b].
Female: b, mandibular teeth.

Espèce Euaugaptilus elongatus - Planche 3 de figures morphologiquesIssued from : G.O. Sars in Résult. Camp. Scient. Prince Albert I, 69, pls.1-127 (1924). [Pl.LXXXIV, figs.1-13].
Female: 1, habitus (dorsal); 2, idem (lateral left side); 3, rostrum; 4, A2; 5, Md; 6, Mx1; 7, Mx2; 8, Mxp; 9, P1; 10, P3; 11, P5.

Male: 12, P5; 13, urosome (dorsal).

Espèce Euaugaptilus elongatus - Planche 4 de figures morphologiquesissued from : R.B.S. Sewell in The John Murray Expedition, 1933-34, Scientific Reports, VIII (1), 1947. [p.204, Fig.52]. With doubt.
Female (from Arabian Sea): A, A2; B, Md; C, Mx1; D, Mx2; E, P1; F, P5.
Nota: Proportional lengths of the prosome and urosome as 70 to 30. Proportional lengths of the various segments of the body (cephalon to caudal rami) as 408:122:61:46:70:119:43:51:80 = 1000. A1 overreaches the tip of the caudal rami by the last 5 or 6 segments. In A2 the endopod and exopod are approximately equal length; exopod 8-segmented, the 3rd devoid of seta. Md possesses a well-developed palp, the two rami being of approximately equal length; the biting edge is much more oblique than in either nodifrons or indicus, the teeth are arranged in 3 groups, possessing 2, 2, 3 teeth respectively. The 2nd basal segment of Mx1 (on the right side) bears 4 setae (instead of 3 in Farran, 1906). In both the Mx2 and Mxp the distal setae are fringed with large \"buttons\" and in each seta one can trace a gradualtransition from hairs, through small spines to \"buttons\". In P1 the 2nd basal segment bears a retroverted seta near the distal outer angle. In P5 the 2nd basal segment bears an extremely long, delicate seta, the total length of which is about twice the length of the exopod.
