Habitat.—South-west Atlantic, Station 318, depth 2040 fathoms.
7. Aulographis stellata, n. sp. (Pl. [103], figs. 23, a-c).
Radial tubes club-shaped, gradually thickened towards the distal end. Terminal branches stellate, numerous (five to ten or more), diverging in all directions, smooth, straight or slightly curved, slenderly conical, three to five times as long as the distal breadth of the tube. The branches are very variable in size, sometimes very small (figs. a, b).
Dimensions.—Length of the tubes 0.4 to 0.8, breadth 0.02; branches 0.01 to 0.02.
Habitat.—Indian Ocean, Madagascar (Rabbe), surface.
8. Aulographis penicillata, n. sp.
Radial tubes slender, cylindrical, of equal breadth. Terminal branches pencil-shaped, smooth, very numerous (twenty to thirty or more), diverging outwards, curved, eight to ten times as long as the breadth of the tube, very thin and fragile, resembling a brush.
Dimensions.—Length of the tubes 1.0 to 1.5, breadth 0.02; branches 0.15 to 0.2.
Habitat.—North Atlantic (Antilles), Weber, surface.
9. Aulographis pistillum, n. sp. (Pl. [105], fig. 6).
