Habitat.—Antarctic Ocean, Station 157, depth 1950 fathoms.
Genus 93. Elaphococcus,[[127]] Haeckel, 1881, Prodromus, p. 450.
Definition.—Astrosphærida with one simple lattice-sphere, covered with forked or dichotomously branched radial spines (the stem of the spine always forked).
The genus Elaphococcus differs from the preceding Cladococcus in the mode of ramification of the radial spines. These are forked; and the forked branches are either simple, again forked, or dichotomously ramified.
Subgenus 1. Elaphococcinus, Haeckel.
Definition.—Pores of the shell regular, of nearly equal size and similar form.
1. Elaphococcus furcatus, n. sp.
Pores of the spherical shell regular, hexagonal, four times as broad as the bars; four to five on the radius. Radial spines, arising from all the nodal-points of the network, cylindrical, as long as the radius, simply forked at the distal end; both branches half as long as the undivided part.
Dimensions.—Diameter of the shell 0.08, pores 0.01, bars 0.0025; length of the spines 0.04, breadth 0.004.
Habitat.—Tropical Atlantic, Station 348, surface.
