2. Cœlotholus cruciatus, n. sp.
Eight styles of equal length, straight, twice as long (in their free part) as the diameter of the dense fork-thicket. Anchor-pencils of about equal size throughout their whole length. Each of four primary frontal tubes is divided into two equal, widely divergent branches; the anterior branches of the right side are diametrically opposed to the posterior branches of the left side, so that all eight together form a double cross.
Dimensions.—Diameter of the whole body 20, of the fork-thicket 4.0.
Habitat.—South-Western Pacific (off Sydney), Station 164A, depth 1200 fathoms.
3. Cœlotholus ancoratus, n. sp.
Eight styles of different lengths, slightly curved. Anchor-pencils gradually tapering from the proximal to the distal end. Each of the four primary frontal tubes is divided into two divergent branches of different lengths; the anterior (or pectoral branch) twice as long (in the free part) as the diameter of the fork-thicket, the posterior (or tergal branch) three times as long.
Dimensions.—Diameter of the whole body 20, of the fork-thicket 3.2.
Habitat.—Indian Ocean (Sunda Strait), Rabbe, surface.
Genus 732. Cœlothauma,[[348]] Haeckel, 1879, Sitzungsb. med.-nat. Gesellsch. Jena, Dec. 12, p. 6.
Definition.—Cœlographida with two paired lateral frenula on each galea, without external lattice-mantle, armed with twelve styles (three pairs of styles on each valve).
