mM, GM, For 
Af denne Søfjær have vi kun en Stump, nemlig hele 
Stilken og den nederste Del af Rachis, hvor der findes 
blot en enkelt, fuldt udviklet Polyp, da Sarcosomaet ovenfor 
' Slegten opkaldt efter den som Naturforsker bekjendte Biskop 
Gunnerus. 
Below the cells on the dorsal side, two diagonal 
series of small round zooids are seen (fig. 11, b); placed, 
3 in each series; these, present nothing particularly remark- 
able. | 
The polyps are retractile, and are about twice as 
long as the cells; they are furnished with 8 thick tentacles, 
having thick, short pinnules, placed pretty far apart 
(fig. 12). 
Both, the cells and the polyps, are largest at the 
middle of the rachis; 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 eaeh side. The terminal polyp, which is situated 
on 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. Im one 
specimen, fully developed ova were observed in the oral 
aperture of such a zooid (fig. 13); and were, presumably, 
about to be discharged m order to be impregnated; be- 
cause, Cladiscus Köllikert 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.

both sides of the mesial furrow, by 
bell-shaped zooids. The cells are cylindrical, and smooth, 
and, are placed in alternating series (3 in each). Below 
the cells on 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.
