. The Danish Ingolf-expedition. Marine animals -- Arctic regions; Scientific expeditions; Arctic regions. COPEPODA 139 fc?. Size of speciineu from Thor vSt. 183 was 5-35 111111.; anterior 4-08111111.; iircsoiiic 1-27. The rostrum and the frontal keel are scarcely different from those of the adult female. The body is more slender, and the lateral corners are rounded and symmetrical. The abdomen is scarcely different from that of the two preceding species. The aiifrttuiilae extend about to the end of the third abdominal somite, and are also in other respects similar to those of the preceding species. The antennae are practically like those of the female, but in the Re I a small conical process was observed medially, apparently bearing a delicate seta. The manducatory portion of the mandilnthie possesses posteriorly one or two rudimentar\- teeth. The i/iaxillulae have short soft aj)pendages in Li i—2; the Le has 2 short and 6 long setae, and the 10 setae of the Re are as usual in the male not .shortest in the middle; the Li 3 has 3 setae, and the Basp. as well as Ri have a similar luimber of setae as in the fe- male, but they are softer. The maxillae and iiinxillipcds are scarcely different from those of the preceding species. The first pair of legs has as usual a well developed articulation between Re I—II, and the Se Re II is compara- tively short; the pes II—IV are scarcely different from those of the females. The rigJit leg of the fifth pair has the basal seg- ments like those of the preceding species (cf. fig. 3 b PI. V). The right endopodite is in general shape very much like that of U. viiiior (figs 9 a—b PL IV, cf. fig. 3 e PI. V); it is terminally somewhat curved and has here lamellar margins, turned over to establish a gutter-shaped excavation facing forwards and Outwards and backwards a well developed conical tooth is found near the base, and be\-oud this, removed one third of the length of the segment from the base, another striated tooth
