Below the cells on the dorsal sid... two diagonal
series of small round zooids are seen (lig. II, b); placed,
3 in each series; these, present nothing particularly
remarkable.
The polyps are retractile, and are about twice as
long as the cells; they are furnished with K thick tentacles,
having thick, short pinnules, placed pretty far apart
(fig. 12).
Both, the cells and the polyps, are largest at the
middle of tile raeliis; up, towards the superior extremity,
they become somewhat smaller, and in this situation, they
are met with, sometimes two, and sometimes, only one
polyp on each side. The terminal polyp, which is situated
oil the dorsal side, is, barely, half so large as the others.
The generative organs develope themselves in the gastral
cavity of the previously described bell-shaped zooids. upon
their two prolonged septula, and there, form pedunculated
capsules, in which the sexual product developes. In one
specimen, fully developed ova were observed in the oral
aperture of such a, zooid (fig. 13); and were, presumably,
about to be discharged in order to be impregnated;
because. Cladwrv:: KdUikeri does not give birth to living young
ones. The sexes are separated.
The calcareous axis is thin, and round, and extends,
nearly, quite down to the bottom of the terminal vesicle,
where, it becomes extremely slender, and forms a hook.
Colour,
The stalk is white, tending slightly lo yellow. The
cells and polyps are white.
Habitat.
Station No. 321). a few specimens.
Specific Character.
The stalk is 48™ long, thin, erect, and round. The
rachis is 30"" long. The ventral surface is occupied, ou
both sides of the mesial furrow, by diagonally situated,
bell-shaped zooids. Tile cells are cylindrical, and smooth,
and. are placed in alternating series (3 in each). Below
the cells 011 the dorsal side, there are 2 series of small round
zooids. 3 in each series. The axis forms a, hook, almost, at
the bottom of the terminal vesicle. The colour is white.
