Formula for arrangement of tentacles into pseudocycles are: marginal tentacles, 1(dt)2314. 2314.2314... labial tentacles, 2(dt)413.4231. 4312.4312... or 1(dt)341.4231.4312... In each crown, division into pseudo-cycles is difficult in some specimens. Directive labial tentacle (dt) is present. Marginal tentacles number 89-114 (type 110). Labial tentacles number 89-112. When animal not actively feeding, but still extended from tube, distal half to one third of marginal tentacles hang limply with distal quarter coiled loosely. This distal quarter remains coiled when animal withdraws into its tube.

Ciliated tract runs whole length of m1 and a few craspedonemes occupy aboral end. Third mesentery (b1) sterile, 1-1.5 x length of ml.

Mesenterial arrangement is BmbM. All macromesenteries (M, m) fertile, all micromesenteries (B, b) infertile. M1 long, but never reaches aboral pole. Three quarters to all of M1 occupied by ciliated tract and distal three quarters possess craspedonemes. The m1 mesenteries less than half length of M1 with ciliated tract running length of mesentery, distal half with craspedonemes. M2 longer or shorter than M1 and may reach aboral pole. Ciliated tract occupies nearly entire length of M2. After second quartette, M mesenteries reduced in length toward reproductive chamber, m mesenteries all of similar length. Micromesenteries usually very short. B1 usually similar in length to directive mesentery with b1 being half the length of Bl. All the micromesenteries carry considerable amounts of cnidoglandular tract. After second quartette, micromesenteries vary little in length (

The classes of spirulae could be separated on the length of the shaft in relation to the total capsule length. Spirulae 2 is the most common type, found in all tissue except the single chord of filament. Atrichs were found in all organs except the single chord and were uncommon in the labial and marginal tentacle tips. Homotrichs appear to be confined to the column.</paragraph>
