Phronima was taken in great quantities in the surface waters during our southern and northern sections across the Atlantic. In the Norwegian Sea two forms are very important: Parathemisto oblivia (Fig. 424), which lives in the open sea, frequently even in very cold water, and also in the Norwegian fjords ; and Euthemisto libellula, which sometimes attains a length of 4h cm., and lives in the icy waters of the Fig. 422. Cystosoma neptuni, Gu£rin-Mdn£ville. (After Wyville Thomson.) Polar Sea. Both these forms were taken also in the Atlantic, but only in boreal areas (see list, pp. 654-655). A form which lives at great depths in the Norwegian Sea is Cyclocaris guilelmi, taken by the Prince of Monaco off the Lofotens and described by Gran. While capturing turtles at Station 56 we observed a great number of deep-blue Isopoda belonging to the species Idotea metallica. Decapoda. The Decapoda include nearly all the large types of crustaceans, like prawns, lobsters, crayfish, crabs, etc. The first deep-sea expeditions captured a considerable number of decapod crustaceans in the trawls at
