. The depths of the ocean; a general account of the modern science of oceanography based largely on the scientific researches of the Norwegian steamer Michael Sars in the North Atlantic. Oceanography. Fig. 429. Limacina retroversa, Fleming. (From Sars.) Fig. 430. Clio pyramidata, L. (From Boas.) acicula (Fig. 431) and Cavolinia gibbosa (Fig. 432) are characteristic forms. The " whale's food," Clione limacina (Fig. 433), is specially abundant in north- ern waters, and is better known than most of the Gymnosomata. It is 3 or 4 cm. long, perfectly transparent, with red shad- ings and black stomach. In the Polar Sea it may be seen swimming among the ice-floes, but it occurs also in the Nor- wegian Sea, in the Norwegian fjords, and in the Atlantic south of Iceland. The majority of the pteropoda (both species and individuals) are restricted to warm water : in the Atlantic the northern limit for the warm- water forms may be roughly drawn from the Bay of Biscay to New York, and the southern limit from Brazil to the Cape. This area is the real home of Clio pyramidata, C. cuspidata, Creseis acicula, the Cavolinidae, the Cymbulidae, Pneumoderma violaceum, Limacina in flat a, L. lesueuri, L. bulimoides. As with the radiolaria and copepoda, many Fig. 431. Creseis acicula, Rang. (From Meisenheimer.).
