Female (from Bay of Biscay): A, habitus (dorsal); B, idem (lateral left side); C, rostrum (ventral view); D, A2; E, Md (masticatory blade); F, Mx1; G, Mxp; H, P1; I, P2; J, P3; K, P4.
Scale bars = 0.100 mm.

Plate 2 issued from : A. Fosshagen in Sarsia, 1967, 29. [p.315, Fig.4].
Female (from 60°2'30''N, 5°58'E): A-B, habitus (lateral and dorsal, respectively); C, rostrum (ventral view).

Nota: Rostrum large and obtusely rounded. 4th and 5th thoracic segments fused and rounded posteriorly. Urosome 4-segmented. Anal segment as long as the preceding segment. Caudal rami with 4 setae of unequal size.

Plate 3 issued from : A. Fosshagen in Sarsia, 1967, 29. [p.316, Fig.5].
Female: A, A1; B, A2; C, Md; D, Mx1; E, Mx2; F, Mxp; G, P1; H, P2; I, P3; J, P4.

Nota: A1 25-segmented, reaching slightly beyond genital segment. A2: exopod longer than endopod; exopod 8-segmented, with 5 setae on inner border; endopod with prominent anterior part. Md: denticulate process with few spine-like teeth; exopod 4-segmented; endopod with 2 segments of nearly same length. Mx1: well-developed, with 6 lobes all furnished with setae; inner lobe with 6 masticatory spines; endopod with 8 setae. Mx2: 5 lobes with plumose setae; endopod with 1 plumose and 3 smooth setae. Mxp: moderately strong with few coarsely plumose setae along inner margin; endopod 5-segmented with 1 strong seta terminally; the 3 innermost segments of endopod carry fine spines on inner margin. Basipod of all swimming legs devoid of setae. P5 absent.

Plate 4 issued from : A. Fosshagen in Sarsia, 1967, 29. [p.317, Fig.6].
Male: A-B, habitus (lateral and dorsal, respectively); C, distal part of left A1; D, Md; E, Mx1; F, Mx2; G, Mxp; H, P1; I, endopod and exopod of P2; J, P4 (terminal spine on exopod missing); K, P5.

Nota: head and 1st thoracic segment partly fused. Urosome 5-segmented. Left A1 geniculate, 20-segmented, sensory organs on each segment along the whole antenna. A2 and Md much as in female. Mx1, Mx2 and Mxp reduced. P5 biramous; right leg slightly longer than the left; both exopods 3-segmented, both endopods 2-segmented.
