Habitat.—Central Pacific, Stations 271 to 274, surface.
4. Sagoscena pellorium, n. sp. (Pl. [108], fig. 5).
Pyramids subregular, of equal size and similar form, usually five-sided or six-sided, crowned at the distal end with three to six divergent apical spines, which bear an irregularly spinulate terminal knob. (The size and form of the apical spines is here very variable, as well as the number of the edges of the pyramids, which varies between three and six.)
Dimensions.—Diameter of the sphere 3.2, length of the bars 0.15 to 0.25, breadth 0.008.
Habitat.—Antarctic Ocean, Station 156, surface.
5. Sagoscena cruciarium, n. sp.
Pyramids subregular, usually six-sided (intermingled with single five-sided and seven-sided or eight-sided forms), crowned at the distal top with three divergent, slender, apical spines, each of which bears three to six regular cruciate verticils; the four crossed lateral branches of each verticil bearing a spinulate terminal knob. (Similar to Sagoplegma scenophora, Pl. [108], fig. 13.)
Dimensions.—Diameter of the shell 2.5, length of the bars 0.2 to 0.3, breadth 0.004.
Habitat.—North Pacific, Stations 240 to 244, surface.
6. Sagoscena debilis, n. sp.
