Habitat.—Tropical Atlantic, Station 347, depth 2250 fathoms.
14. Aulographis flosculus, n. sp. (Pl. [105], fig. 10).
Radial tubes club-shaped, straight, tapering gradually towards the rounded proximal end. Terminal branches nine to twelve, stout, conical, twice to three times as long as the breadth of the tube, studded with irregular secondary spines, connected in the proximal half by a solid, cap-shaped, flinty lamella, so that the terminal corona resembles a flower. The hollow canal of the tube sends a thin branch into each branch of the crown.
Dimensions.—Length of the tubes 1.2 to 1.8, distal breadth 0.04 to 0.05; branches 0.1 to 0.2.
Habitat.—North Atlantic, Færöe Channel (Gulf Stream), John Murray, depth 600 fathoms.
Subgenus 3. Aulographidium, Haeckel.
Definition.—Terminal branches of the radial tubes armed with terminal spathillæ (or whorls of small radial teeth), but without lateral denticles or spines.
15. Aulographis furcula, n. sp. (Pl. [103], figs. 10, 11).
Radial tubes cylindrical, slender, slightly curved. Terminal branches usually two, sometimes on single tubes three, eight to ten times as long as the tube is broad, strongly curved, ascending vertically from a horizontal base, with a terminal spathilla of four crossed teeth at the distal end.
Dimensions.—Length of the tubes 0.6 to 0.8, breadth 0.006 to 0.008; branches 0.06 to 0.08.
