. The Danish Ingolf-Expedition. Scientific expeditions; Arctic Ocean. 112 COPEPODA The measurements and appendages differ scarcely from those of G. Krtippi. The antennae are like those of G.

The third segment of the maxillipeds is 1-2 as long as the first and second combined, and 27 as long as the endopodite, but in other respects this pair of appendages is scarcely different from those of G. Kriippi. The first pair of legs is like that of Gaidius brevispinus (PI. Ill fig. i g), but the articular line between Re I—II is indicated anteriorly, though wanting posteriorly; the Se of Re I and II are wanting. The Se of Ri I of the pes II is wanting; the St, which has about 30 teeth, is a little longer than Re III, which is again a little longer than the Re I—II; no glandular pore is found at the base of Se Re I. The pes III—IV have a secretory pore at the base of Se Re 1; the basipodite of the third pair has a marginal row of setae, but that of the fourth pair is completely smooth. The fi/t/i pair of legs (text-fig. 28b) is in most features like that of Gaet. Kruppi (PL III fig. 3d); the right leg is less slender, especially the third basipodite, which is, however, less clumsy than in G. brevispiinis (PI. Ill fig. I h); the first segment of the right exopodite has exteriorly a slight concavity almost in the middle and, proximally to it, a slender seta (Se Re I), thus indicating that this segment really corresponds to Re IcNill; the Re III differs from that of G. Kruppi by the structure of the terminal portion (that distal to inner process) which is only two thirds as long as the basal part and not in the least as long as, and, proximally to a hair-shaped terminal j^art, has an inner lamina in the distal half. The right endopo- dite when observed from behind, is almost completely like that of 6". Krnppi (fig. 3d), but v
