Original Description Shell conical, with three slight strictures. Length of the four joints = 4: 14: 5: 3. Cephalis large, conical, with two stout pyramidal, divergent horns of twice the length. From its base (in the middle of the collar stricture) arise three internal, downwardly divergent ribs, which are prolonged on the outside of the upper half of the thorax into three stout, pyramidal, lateral spines (similar to the horns). The fourth joint, with wide open mouth, was the broadest, but not fully developed in the single specimen observed. Pores subregular, hexagonal, with thin bars. Size: Length of the shell (with four joints) 0.02, breadth 0.09. Length of the single joints, a 0.02, b 0.07, c 0.025, d 0.015. Editors' Notes Haeckel listed Stichopilium bicorne under the subgeneric name Triacartus, but did not include the subgeneric name in the species name.[comment from RadWorld database]
