Shell subspherical, rough, with subregular circular pores. Basal plate with three pores (?). Apical horn simple, conical, half as long as the shell. Feet cylindrical twice to three times as long as the shell, semicircular, with a strong conical tooth in the middle of their outer convex edge; their distal ends convergent, divided into a bunch of numerous short irregular branches.
Dimensions.—Shell 0.7 long, 0.08 broad; horn 0.03 long, feet 0.15 to 0.25 long.
Habitat.—South Atlantic, Station 332, depth 2200 fathoms.
6. Dendrospyris ramosa, n. sp.
Shell nut-shaped, spiny, with irregular roundish pores. Basal plate with three pairs of pores. Apical horn cylindrical, spinulate, twice to three times as long as the shell. Feet as long as the horn, S-shaped, widely divergent, irregularly branched, with widely distant pointed branches.
Dimensions.—Shell 0.08 long, 0.12 broad; horn and feet 0.2 to 0.3 long.
Habitat.—North Atlantic, Station 353, depth 2965 fathoms.
7. Dendrospyris arborescens, n. sp. (Pl. [85], fig. 9).
Shell nut-shaped, tuberculate, with subregular circular pores. Basal plate with four central larger and ten to twelve peripheral smaller pores. Apical horn cylindrical, twice as long as the shell, in the distal half spinulate or tuberculate. Feet about three times as long as the shell, cylindrical, nearly vertical, in the distal half irregularly branched, with dense bunches of aggregated blunt branches.
Dimensions.—Shell 0.07 long, 0.09 broad; horn and feet 0.12 to 0.18 long.
