Pes I has the articulation between the Re I—II better developed than in the female, but the Se of Re I is wanting; the pes II shows a similar sexual difference. Pes F dext. has, about in the middle, an almost complete articular line between Re I and II; proximally to this a short tooth is found exteriorly, which is indicated in E. norvegica; the Re III is terminally somewhat hollowed, and less widened. The Re II—III pes V sin. are distinctly shorter; the ringed appendage is comparatively short, and the serrated process is moderately hollowed between the two rows of teeth; the left endopodite has only one single segment (text-fig. 47 g). Yq (St. V). Size of specimen from Thor 1904 St 154 was 771 mm.; anterior division (3'5i -}- 2'3) = 5'8i; urosome 1-9 mm. Hansen's specimen measured 7 mm. This stage is easily distinguished from the corresponding stage of E. norvegica by the more obtusely pointed lateral corner of the fifth thoracic somite (text-figs 47 h—j). The differences in the.
