. The Danish Ingolf-expedition. Marine animals -- Arctic regions; Scientific expeditions; Arctic regions. 70 CRUSTACEA MALACOSTRACA. V. 60 A. Orchomene (lsevipes?) (Fig. 12, partim.). Occurrence. The "Iiigolf" has W. of Greenland (St. 78: 6o°37'N., 52°oo'W., 1505 m., between spieulae of sponges) secured a number of specimens (3 spec, up to abt. 8 mm., abt. 50 spec. abt. 5 mm.), which probably are identic with 0. Icevipes. I have dissected the biggest specimen ($ without marsupial plates, 8 mm.) from this station, and it totally agrees with 0. krvipcs except in the following respects.

Lateral lobes of the head much broader. Eyes distinct, but ocelli colourless. Ant. 1: 1. joint in peduncle barrel-shaped as is usually the case, not cylindrical; flagellum 8-articulate, accessory flagellum 4-articulate. P. 5—p. 7: the dentition on the hind edge of 2. joint is a little more distinct; number of teeth on anterior edge of the same joint is a little greater. Epimeral part of 3. segment of the metasome has abt. 13 middle-sized teeth; the inferior hind corner acute-angled, not almost right-angled. Telsou has 3 (not 2) pairs of dorsal spines. *6i. Orchomene faeroensis n. sp. (fig. 13). Occurrence. The "Thor" has secured 1 3 ad. of this new species. S. W. of the Faeroes: "Thor" St. 99 ( 1904): 6l°l5'N., 9°35'W. 900 m. 1 J ad., 7 mm. The present species is very closely allied to 0. pectinata, but differs from this species in some few respects. Eyes not visible. Lateral corners of the head and epistomal plate almost totally as in 0. pectinata. (Both pairs of antennae have calceoli). Ant. 1: flagellum > 11 joints (apex is lost), accessory flagellum5-articulate. Ant. 2 long, > 30 joints in flagellum (apex lost), which is abt. half the length of the body. Pereiopoda almost totally as in 0. pectinata with the single exception, that basal plate in p. 7 is somewhat narrower, especially in the distal part. Epimeral plate of 3. meta- some seg
