Habitat.—North Pacific, Station 256, surface.
5. Sagenoscena spathillata, n. sp.
Pyramids more or less irregular, of different sizes and various forms, each composed of four to eight convergent rods and a central axial rod. The latter is prolonged into a free apical spine, which bears at the distal end a spathilla of eight to twelve recurved teeth, and often beyond it a second similar verticil.
Dimensions.—Diameter of the sphere 4.0, length of the bars 0.1 to 0.2, breadth 0.002.
Habitat.—Arctic Ocean, Greenland (Olrik).
6. Sagenoscena cruciata, n. sp.
Pyramids very irregular, of different sizes and various forms, each composed of six to nine convergent rods and a central axial rod. The latter is prolonged into a free apical spine, which bears three to five cruciate verticils, each composed of four perpendicularly crossed lateral branches which bear at the distal end a spinulate knob (similar to Sagmidium crucicorne, Pl. [108], fig. 9).
Dimensions.—Diameter of the sphere 1.0 to 1.2, length of the bars 0.06 to 0.09, breadth 0.001.
Habitat.—Central Pacific, Station 266, depth 2750 fathoms.
