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).
Collophidium serpentinum, Haeckel, 1882, Manuscript.
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.
8. Collozoum vermiforme, n. sp. (Pl. [3], figs. 6, 7).
Collophidium vermiforme, Haeckel, 1882, Manuscript.
Central capsules cylindrical, much elongated, five to ten times (sometimes twenty to fifty times) as long as broad, snake-shaped or worm-shaped, very irregularly curved and contorted. Numerous oil-globules constantly present, forming in the axis of every capsule a double series of alternating rose-coloured globules. (This species is nearly allied to the preceding; but its capsules are thicker and shorter, and the oil-vesicles in them are arranged not in a single, but in a double row.)
