Column purple aborally merging to brown orally. Brown coloration may vary from dark to pale yellowish brown. Marginal tentacles all have a pale longitudinal stripe on each side with oral and aboral faces coloured, which gives them a distinctly striped appearance. Two tentacle colour forms: one pale yellowish brown the other deep purplish maroon. Labial tentacles pale cream. Oral disc deep brown in colour.

M2 and M3 also long, almost reaching to aboral pole. Half to two-thirds of M1 occupied by ciliated tract and distal three-quarters carries craspedonemes. The m1 mesenteries less than half length of M1, ciliated tract confined to proximal three-quarters. Slight reduction in length of m mesenteries as they approach multiplication chamber. M mesenteries undergo substantial reduction in length after second quartette. Micromesenteries generally very short, B mesenteries twice length of b. All micromesenteries possess cnidoglandular tract. After first quartette, micromesenteries vary little in length (
