Hansen, 1905

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.

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.

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