Dimensions.—Length of the central capsules 0.2 to 0.3, breadth of them 0.1 to 15.
Habitat.—North Pacific, Station 244, surface.
5. Collozoum ellipsoides, n. sp. (Pl. 3, figs. 8, 9).
Central capsules regularly ellipsoidal, very large; their longer diameter once and a half to twice as large as the shorter. In every capsule fifty to eighty oil-globules.
Dimensions.—Length of the central capsules 0.3 to 4, breadth of them 0.2.
Habitat.—North Atlantic, Færöe Channel (Gulf Stream), surface, John Murray.
Subgenus 3. Collophidium, Haeckel.
Definition.—Form of the central capsules cylindrical, often snake-like, contorted, with one axis much prolonged, several times longer than the transverse axis.
6. Collozoum contortum, n. sp.
Central capsules cylindrical, three to four times as long as broad, C- or S-like curved, transparent, without oil-globules.
Dimensions.—Length of the central capsules 0.2 to 0.3, breadth 0.06 to 0.08.
Habitat.—Tropical Atlantic, Station 347, surface.
7. Collozoum serpentinum, n. sp. (Pl. 3, figs. 1-3).
Central capsules cylindrical, filiform, much elongated, ten to one hundred times, sometimes two hundred to four hundred times as long as broad, snake-shaped or worm-shaped, curved and contorted in the most irregular manner, often spiral or twisted into a large nodule. Numerous oil-vesicles constantly present, forming one series of globules in the axis of every capsule; distance of the globules, one from another, and also from the capsule-membrane, about equal to their diameter. (This interesting and very curious form was very frequently observed living by me in the Canary Islands, in January 1867; the jelly-colonies were commonly spherical, and contained fifty to two hundred or more capsules of very different size and form.)
Dimensions.—Length of the central capsules 1 to 10, sometimes 20 to 40 mm.; average breadth 0.1 mm.
Habitat.—Canary Islands, Lanzerote, Haeckel, surface.
