øvrige, nemlig 30""" lang, 6""" bred og med 25""" lange
Tentakler.
Endnu paa dette temmeligt udviklede Exemplar har
man en bilateral Ordning af Polyperne, omendskjønt det
ved en overfladisk Betragtning ser ud, som om Polyperne
ere stillede i en kredsformig Dusk uden al Symetri. Det
er forst ved at hugge Polyperne meget omhyggelig ud fra
hverandre, at den bilaterale Ordning kommer tilsyne.
Polyperne ere cylindriske, have paa deres ydre Flade,
som alle de foregaaende, 8 gulbrune Linier, der betegne
Insertionsstederne for de 8 Septa paa den indre
Krops-flade. Igjennem Kropsvæggen skinner det lange, stærkt
foldede Svælg. Tentaklerne ere som paa de tidligere
beskrevne, hvilket ogsaa ei- Tilfældet med Mundskiven
og den 8 læbede Mund. Kun den ydre Kække (9) Polyper
har udviklede Gencrationsorganer med Æg i forskjellige
Stadier.
Axen ender nedentil med en liden Klump lige i Bunden;
den dreier sig i lange Spiraler efter Længden til op imod
den skedeformigc Udvidning, hvor Spiralerne blive kortere.
Paa Spiritusexemplarer, hvor Coenenchymet er
sammenfaldt, er Stilken firkantet.
Parven.
Den bulbøse Del er næsten kastaniebrun men bliver
lysere op iinod dens øverste Parti, saa at hele Stilken samt
Rachis er straagul, spillende lidt i det brunlige. Polyperne
lys-kastaniebrune; Tentaklerne lidt lysere paa den aborale
Flade men mørkere paa Halvdelen af den adorale Flade
samt Mundskiven. Mundheberne lys-gulbrune.

Stilken fra Grunden til Rachis 1480""" lang. Den
bulbøse Del er tenformig, fladtrykt paa Ventral- og
Dorsalfladen, 500""" lang; dens nederste Del er omtrent 50’""’i
Omkreds, ender i en ovoid Flade, der løber ud i en stump Spids,

pludselig udvider sig og indtager da en Omkreds af 100""". Nu
round, nearly, the whole rachis, as both the series unite
with each other, leaving only, a breadth of 6""" of the
ventral surface exposed. The polyp which actually unites
these two series together about the middle of the dorsal
surface, is a. little smaller than the others, being 30""" long,
and 6""" broad, and the tentacles 25""" in length.
Still, in this pretty fully developed specimen, we find
a bilateral arrangement of the polyps; although, on a
superficial observation it appears, as if the polyps are arranged
in a crescent-formed tuft, without any symmetry. It is
only, when the polyps are carefully separated apart from
each other, that the bilateral arrangement becomes
apparent.
The polyps are cylindric, and like all the previous
specimens, have 8 brownish-yellow lines on their exterior
surface, denoting the points of insertion for the 8 septa
on the inner surface of the body. The long, much
folded gullet, appeai-s visible through the wall of the body.
The tentacles are like those of the specimens already
described; and, this is also, the case with the oral disk,
and the oral aperture with it’s 8 labiæ. The outer
series (9) of polyps alone, has generative organs developed,
containing -ova in various stages.
The axis terminates beneath, in a small lump, situated
quite at the bottom; it twists itself in long longitudinal
spirals until in proximity to the sheath-formed dilation, at
which point the spirals become shorter.
In the specimens preserved in alcohol, the sarcosoma
is shrunk, and the stem appears quadrangular.
Colour.
The bulbous portion is almost chestnut brown, but
becomes lighter up towards the superior portion, so that the
entire stem, as well as the rachis, is straw-yellow, tending
a little to brownish colour. The polyps are a light chestnut
brown colour. The tentacles are a little lighter on the
aboral surface, but darker on the half portion of the
ador-al surface and oral disk. The labia1 of the oral aperture
are light-brown yellow.

The stem measures 1480""" in length from the base
to the rachis. The bulbous part is spindle-formed, and
flattened on the ventral and dorsal surfaces. It is 500"""
long at it’s broadest part, and it’s inferior part is about
50""" in circumference, terminating in an ovate surface
which projects in a blunted point. It increases a little in
