The basipodite has 5 setae, the Ri I 3, Ri II 4 (one very delicate), and the Ri III 3 setae. The pes I has the articular membrane between Re I—II fairly well developed anteriorly (text- figs 48 b—c), and the Se Re I is fairly well developed. The Se Re II scarcely extends to the end of the short Se i Re III, and the Se 2 Re III extends somewhat beyond the middle of the third division (cf. Wolfenden's fig. 9, p. 134).

Lateral corner X 18. seem in main features to be like E. norvegica; the oral surface of the labrum is somewhat different from E. norvegica, as seen by comparing figs 6 a and 3 a; the lateral anterior group has about 60 rather strong short spines, the groups 1—6 are more regularly placed. The area in front of the lamina labi- alis differs by the less square, more rounded, lateral group of short hairs. Y$ (St. V). Size 8-3 mm.; anterior division 6 mm.; urosome 2-3 mm. The lateral corners of the thorax are regularly rounded; in other respects, except the usual ones, this stage is scarcely different from the adult females (text-fig. 48 f). Occurrence. This species was gathered at the following stations by the Ingolf Expedition. ^/7 1896 St. 104 66^23 L.
