The genital somite, which is 1-3 as long as wide and i;a as long as deep, is in dorsal view slightly asymmetrical, and has the lateral margins strongly convex, somewhat in front of the middle. The genital prohtberance has in lateral view a wing-like anterior process, sometimes slightly concave in the middle, and a more dorsal and posterior process, separated from the former by a distinct incision (text- figs 51 a—e). In ventral view the vulva shows some similarity to Wolfenden's figure 53 a, which is, however, too incomplete for a detailed comparison, and is distinctly different from the mentioned species of this group. The posterior incision in the median plate is not observed; the anterior tri- angular point, of which an oval plate is found, is just indicated. The antennulae extend just beyond the end of the third thoracic tergite, but not to the end of the cephalo-thorax; the segments 24^25 are as long as the segment 19; the appendages scarcely show differences from those of E. norvegica. The mouth-limbs are scarcely different from those of £. barbata; 23*.
