Hansen, 1905

Description:
Body more or less semicylindrical in shape, the eyes are lateral and of normal size. Antenna 1 scarcely reaching the anterior lateral angle of the pereion; peduncle with article 3 slightly shorter than article 2; flagellum robust in both sexes. Antenna 2 peduncle of 4 distinct articles. Maxillipedes without coupling hooks on the inner border. The dactyls of pereiopods 1 to 3 are not markedly larger than those of pereiopods 4 to 7. Pereion segments 2 to 6 with the posterior corners of the coxal plates produced into fairly long processes, those on segment 6 longer than in any other Eurydice species. Pleon with five distinct segments plus one (the uropodal segment) fused with the telson. Pleon segment 5 not markedly reduced, with the lateral borders contributing to the body outline. Pleopod 1 with both rami thinly chitinised and fringed with setae. Pleotelson sharply narrowing posteriorly; posterior border emarginate with two conspicuous spines at each lateral corner on each side of the row of plumose setae. Uropods lateral, not arching dorsally and with the pleotelson forming a terminal fan. Uropod peduncle not markedly produced backwards alongside inner border of endopod; articulation between peduncle and endopod short.
Body length up to 9 mm.

Habitat:
Of several Eurydice species occurring in the North Sea, this is the most likely to turn up occasionally in surf plankton or in intertidal sand.

Distribution:
It ranges from the southern North Sea down the Atlantic coast of France into the Mediterranean.
