Enallopsammia rostrata (Pourtalès)

(tab. 4; fig. 5)

Remarks. B-rhabdoids (3) from tentacles are similar to those of the other dendrophylliids, but are smaller in size. Two size classes of p-rhabdoids D (2) could be distinguished in mesenterial filaments (fig. 5H, I). Holotrichs II were absent from tentacles and mesenterial filaments.

Remarks. A variety of b-rhabdoid similar to b-rhabdoid (2) was observed in mesenterial filaments (b-rhabdoid1: fig. 6L), presenting a tubule arranged in fewer coils, and a capsule more elongated and cylindrical. Opaque capsules occurred in the tentacles (fig. 6G).
