Espèce Euaugaptilus mixtus - Planche 1 de figures morphologiquesissued from : O. Tanaka & M. Omori in Publs Seto Mar. Biol. Lab., 1974, XXI (3/4). [p.249, Fig.26]. As Euaugaptilus propinquus.
Female: a, habitus (dorsal); b, head (lateral); c, rostrum (frontal view); d, last thoracic segment and urosome (lateral left side); e, A2; f, Mx1; g, Mx2; h, Mxp; i, P1; j, P5.
Nota: The urosome segments and furca are in the proportional lengths as 47:12:18:23 = 100. Prosome and urosome are in the proportional lengths as 75:25. Furca 1.5 times as long as wide.
The present specimen differs from the description and figures of Sars (1925).

Female: i, mandibular teeth.

Female: 1, habitus (dorsal); 2, idem (lateral left side); 3, forehead (lateral); 4, rostrum; 5, A2; 6, Md; 6a, Md (masticatory edge of the same appendage, enlarged); 7, Mx1; 8, Mx2; 9, Mxp; 10, P1; 11, P2; 12, P3; 13, P5; 14, urosome.


Espèce Euaugaptilus mixtus - Planche 4 de figures morphologiquesissued from : K. Hulsemann in Crustaceana, 1967, 12 (2). [p.164, Figs.1-11].
Female (from N Azores; specimen from Lysholm & Nordgaard collection): 1-2, habitus (dorsal and lateral, respectively); 3, forehead with rostrum (lateral); 4,A2; 5, Md (mandibular palp); 6, Md (biting edge); 7, Mx1; 8, Mx2; 9, Mxp; 10, P1; 11, P5.
Nota: The present specimen differs from the description of Sars (1907) in the somewhat longer A1. Head and 1st thoracic segment separate, 4th and 5th fused.urosome less than one third of length of cephalothorax. Genital segment slightly longer than the two following segments together. Anal segment longer than preceding. caudal rami as long as anal segment. A1 25-segmented, exceeds end of caudal rami by nearly 3 segments; Exopod of A2 about as long as 1st endopodal segment, 8-segmented (segments 7 and 8 partly fused). Mx1 with 3rd inner lobe and endopod lacking; 2nd inner lobe and 2nd basipodal segment each with 1 seta; exopod with 6 setae, the strongest two situated distally; external lobe with 5 setae. Mx2 with on first six lobes: 2, 1, 2, 2, 2, 1 setae; Mxp with on first two segments: 1, 2 (1 on the fig.9 !), 3, 2, 2 setae; long setae on endopods of Mx2 and Mxp equiped with buttons. 2nd exopodal segment of P1 with short external spine.
