Original Description
Both arms different in size and form; larger arm club-shaped, four times as long as broad, at the distal end three times as broad as at the base, and twice as long as the smaller arm, which resembles a stalked knob, with thin basal peduncle and spherical distal part. Ends of the two arms thorny (with numerous smaller, and three to five larger spines); one very large conical terminal spine on each pole of the main axis.
Radius of the larger arm 300µm, of the smaller 150µm; distal breadth of the former 60µm, of the latter 40µm; basal breath 20µm.
