5 """ brede med 25""" lange Tentakler til 45’"’" lange, 10""" brede
og med 45""" lange Tentakler. Til Siden og udenfor denne
Række er stillet 3 Polyper i en krumbøiet Linie, der ere
af omtrent lige Størrelse, 42""" lange, 12""" brede;
Tentaklerne lige lange som Kroppen, Fig. 26, 8, 8, 8. Disse
to Rækker dorsal-laterale Polyper omgives af 5 store,
laterale Polyper, der staa i en Halvkreds og slutte sig paa
Ryggen fuldkommen til de tilsvarende 4 paa venstre Side,
som de ligne i et og alt, imedens der paa Bugsiden bliver
et temmelig stort, aabent Rum, Fig. 26.
Den bilaterale Symetri er temmelig godt bevaret, og
det er paa dette Exemplar som paa de tidligere omtalte,
at da Racliis har udvidet sig saa betydeligt i Bredden og
er dreiet, faa Rækkerne en næsten horizontal Stilling paa
den saagodtsom plaue Rygside; imidlertid viser en nøiagtig
Undersøgelse, at Rækkerne, naar undtages Centralrækken,
have en lidt skraa Stilling forfra bagtil, nedenfra opad, saa
at Polyperne i Regelen naa hen til Midten af Rygfladen,
hvor især cle laterale støde sammen uden at efterlade
noget synderligt Mellemrum, saaledes som Tilfældet
ialinin-dclighed er paa Ventralfladen.
Polyperne ere som paa de Foregaaende. De to yderste
Rækker Polyper, der have fuldt udviklede Kjønsorganer, ere
Hanner; de centrale og dorsal-laterale ere golde.
Farven ligesom paa No. 9. Hele Polypstokken
overtrukken med et gelatinøst Slim.
Axen som paa No. 9.

Stilken er fra den nederste Ende til Rachis 1900’"’"
lang. Den bulbøse Del er 345""" lang, dennes nederste
Halvdel er rund, 60""" i Omfang strax ovenfor den konisk
afstumpede Ende ; tlen øverste Halvdel er firkantet, ogsaa
60""" i Omfang; Midtpartiet er noget smalere. Omtrent
430’"’" fra den øverste Del af Bulbus begynder Stilken at
dreie sig noget efter Længden og fortsætter med Dreiningen
helt op til Enden. Paa det smaleste er Stilken 4""".
Den skedeformige Udvidning er 55’""’ lang, 11""" bred,
5 polyps increase in size; according, as they are arranged
posteriorly on the dorsal surface; rising from 25 """long, 5"""
broad, with 25""" long tentacles; up to 55""" long, 10"""
broad, with 45""" long tentacles. To the side, and outside
of this series, 3 polyps are arranged in a curved line, and
these, are nearly uniform in size, viz 42""" in length, and
12""" in breadth, with the tentacles of same length as the*
body (fig. 26, 8, 8, 8). These two series of dorso-lateral
polyps are surrounded by 5 large lateral polyps, which are
placed in a semicircle, and completely unite on the dorsal
side, with the corresponding 4 polyps on the left side,
which they resemble in all respects; whilst, upon the
ventral surface, a pretty large open space is left
(fig. 26).
The bilateral symmetry is tolerably well preserved;
and in this specimen, like those already spoken of, the
series assume a nearly horizontal position on the almost
flat dorsal surface, owing to the rachis becoming so much
dilated in breadth, and also, so much twisted. A minute
examination, however, shows, that the series has a
somewhat diagonal arrangement, running from front to back,
and downwards to upwards, so that, in general, the polyps
reach to the middle of the dorsal surface; where, the
lateral ones, especially, unite with each other, without leaving
any considerable interspace, such as is the case, generally,
on the ventral surface.
The polyps are similar to those of the preceding
specimens. The two exterior series of polyps, have fully
developed sexual organs, and are males. The central and
dorso-lateral polyps are sterile.
The colour is similar to that of No. 9 specimen. The
entire polypdom, is coated with a gelatinous mucous.
The axis is similar to that of No. 9 specimen.

No. 11 specimen.
Pl. VIII, fig. 27.
The stem measures 1900’"’" from the inferior
extremity to the rachis. The bulbous part is 345’"’" long, and
it’s inferior half portion is round; it is 60""" in
circumference immediately above the conically blunted extremity.
The superior half portion is quadrangular, and is also
60""" in circumference. The middle portion is somewhat
narrower. About 430""" from the superior part of the
bulb, the stem commences to twist itself somewhat,
longitudinally, and it continues the twisting, right up to the
extremity. The stem is 4""" thick at it’s narrowest point.
The sheath-formed dilation is 55""" long, and 11"""
