den halvrunde Række af 6 store Polyper, fuldkommen lig 
dem, som ovenfor ere omtalte paa høire Side, Fig. 25, 8, 8, 
8, 8, 8, 8. 
Maalene af Polyperne ere foretagne paa Npiritus- 
exemplaret; men paa det levende Exemplar, der er tegnet 
Tab. XI, XII, havde Polyperne en ganske anden Størrelse; 
saaledes vare de i den ydre Række, naar de vare fuldt ud- 
strakte, indtil 100”” lange, 50—60”” i Omkreds ved Grun- 
den og Tentaklerne 70—80”" lange. 
Vi have paa dette Exemplar sogt at fremhæve de 
Rester af en tidligere bilateral Symetri, som endnu ved 
en skrupuløs Undersøgelse kan findes; men yi tilstaa, at 
den bilaterale Regelmæssighed er for en stor Del forsvun- 
den, idet Rachis danner en næsten rund Kvast, hvorpaa 
Polyperne, der udgjøre Duskerne, ere stillede i 3 ring- 
formede Rækker om de 3 Centralpolyper. I første, ydre 
Række ere de 12 store Polyper; denne Række er fuld- 
kommen sammenhængende, saa at Ventralfladen er mdtagen 
af 2 Polyper, Fig. 25, c, c; indenfor denne Række kommer 
en anden Række af 12 noget mindre Polyper, men denne 
Ring er afbrudt paa Ventralfladen, hvor der er en Afstand 
af 5”” imellem de 2 Polyper, der ikke slutte sig sammen, 
Fig. 95, d, d. Endelig kan man forestille sig en 3die, mdre 
Række, der bestaar af 4 Polyper, som forresten staa saa 
uregelmæssigt og usammenhængende, at man kun med Tvang 
kan danne en afbrudt Ring deraf. Imellem den ydre og 
mellemste Kreds, nær Ventralfladen, sees en liden, konisk 
Forhøining, der er en ganske ung Polyp. 
Polyperne ere cylindriske, meget tykke ved Grunden 
og kunne kontrahere sig stærkt, baade efter Længden og 
Bredden. Paa Kroppens ydre Flade, der i udspændt 
Tilstand er glat og uden Folder, sees 8 temmelig brede 
Liengdelinier, der betegne Insertionsstederne for de 8 
Septa. Huden er ikke gjennemsigtig, saaledes som Tilfæl- 
det er paa de tidligere omtalte; thi den er meget stærkt 
kontraheret som Følge af Opbevaringen i Spiritus. Ten- 
taklerne og Mundskiven er som paa No. 7, men ,de 8 
Mundlæber ere større og mere fremspringende. 
Axen gaar lige ned til Bunden af Stokken, hvor den 
ender med en kort Hage. Den er som sædvanligt firkantet 
med 4 dybe Furer og afrundede Kanter; men den er 
meget mere spiralformigt dreiet efter hele sin Længde end 
nogen af de foregaaende. 
Alle 31 Polyper have udviklede Generationsorganer 
og ere Hanner. 
Farven er som paa No. 7; se forresten den i levende 
Live afbildede Figur, Tab. XII, hvor Farven er gjengivet 
med Nøiagtighed. 
35””" in length, and 10”” in thickness, and the tentacles have 
a length of 40” (fig. 25, 7, 7). 
the semicircular series of 6 large polyps appears, exactly 
similar to those spoken of above as pertaining to the 
right side (fig. 25. 8, 8, 8, 8, 8, 8). 
Outside of these 7 polyps; 
The measurements of the polyps are taken from the 
specimen in alcohol, but in the live specimen which is 
seen illustrated on Pl. XI, XII, the polyps had quite 
another size, so that, those in the outer series, when they 
were fully extended, measured up to 100” long, and 
50—60”” in circumference at the base, and the tentacles 
were 70—80”” long. 
We endeavoured im this specimen, to trace 
out the remains of any earlier bilateral arrangement that 
a searching examination might still bring to light; but, we 
confess, that the bilateral regularity has for the most part 
disappeared; whilst, the rachis forms a nearly round knob,

on which, the polyps which compose the tufts, are situated 
in 3 annullar series, around the 3 central polyps. In the 
first outer series, there are 12 large polyps in a perfectly 
continuous series, so that, the ventral surface is occupied 
by 2 polyps (fig. 25, c, 0). 
series of 12, somewhat smaller polyps appears, but this 
series is interrupted on the ventral surface, and here, 
there is an interval of 5”” between the 2 polyps which do 
not unite with each other (tig. 25, d, d). 
Inside this series; another 
Finally, we may 
conceive a 3”¢ inner series, consisting of 4 polyps, which 
otherwise, are situated so irregularly, and unconnectedly, 
that it is only with difficulty, an interrupted ring can 
be formed out of them. Between the external and the 
middle ring; near the ventral surface; a small conical prom- 
inence is observed, this is a quite young polyp. 
The polyps are cylindric, and very thick at the base. 
They are capable of great longitudinal and lateral con- 
traction. On the exterior surface of the body; which in 
the dilated condition is smooth, and free from folds; 8 
rather broad, longitudinal lines are observed, denoting the 
points of insertion for the 8 septa. The integument is 
not translucent; as is the case in the specimens we have 
already spoken of; because, it is very greatly contracted

The axis extends quite to the base of the stalk, 
where, it terminates in a short hook. It is, as is gen-

and rounded but, it is spirally

erally case,

All the 31 polyps have, developed generative organs, 
and are males. 
The colour is like that of No. 7 specimen, and is 
otherwise like the illustration; (Pl. XII) taken from life; 
in which the colour is exactly repeated.
