smalne af paa Midten, men udvide sig igjen noget op
imod Tentakelvanden. Paa den udvendige Kropsflade sees
de 8 Længdelinier for Insertionerne af Septa. Kroppens
Hud uigjeuneinsigtig. Tentaklerne, Mundskiven og
Munden som paa den foregaaende.
Farven er omtrent som paa No. 8. Hele
Polypstok-ken har som sædvanligt et temmeligt tykt, gelatinøst
Overtrade, der let gaar af/ ved Berørelse, og hvorved Overhuden
drages med. Den nederste (bulbøse) Del har en lys,
havannabrun Farve, den øvrige Del er meget lysere brungul.
Hvor det gelatinose Overtræk med Overhuden var borte,
var Sarcosomaets Farve bleg gulhvid. Paa Rachis er
Overhuden fastere, tyndere og har en svag gulbrun Farve.
Polyperne ere smukt kastaniebrune; Pinnulerne ere noget
lysere, imedens Mundskiven er mørkere. Mundlæberne
omtrent af samme Farve som Pinnulerne.
Axen som paa de Foregaaende, kun langtfra saa
dreiet.
Findested.

base, diminishing in thickness at the middle, but again
expanding somewhat, in proximity to the tentacular
margin. On the exterior surface of the body, 8 longitudinal
lines for tin* insertions of septa are observed. The
integument of the body is non-translucent. The tentacles,
oral disk, and oral aperture are similar to the same parts
in the preceding specimen.
The colour is almost similar to that of No. 8
specimen. The entire stalk of the polyp lias, as is commonly
the case, a rather thick gelatinous covering, which is readily
removed by contact, and which takes the cuticle along
with it. The inferior (bulbous) part has a light Havana
brown colour; the remaining part, is a much lighter
brownish-yellow. Where the gelatinous covering and Cuticle
were absent, the sarcosoma’s colour was pale yellow-white.
On the rachis, the cuticle is more consistent, and is
thinner, and has a light yellow-brown colour. The polyps are
a beautiful chestnut brown. The pinnules are somewhat
lighter in colour, whilst, the oral disk is darker. The
labia1, of the oral aperture are of nearly the same colour
as the pinnules.
The axis is similar to that of the preceding specimen,
only, not nearly so much twisted.

Stilken fra Grunden til Rachis 1820""" lang. Den
bulbøse Del er 340""" lang, aldeles rund, næsten lige tyk
overalt, kun dens øverste Parti, der er 50""" i Omkreds,
er noget fladtrykt, næsten firkantet; dens nederste Ende
er tvers afskaaren og 55""" i Omkreds. Den skedetbrmige
Udvidning er 180""" lang, 15""" bred, tæt besat med Zooider,
der længere ned paa Stilken Orclne sig i Rækker paa
Yen-tral- og Dorsalsiden. Fra den bulbøse Del aftager Stilken
i Tykkelse, saa at den op imod den skedeformige
Udvidning kun er 3.5""" tyk. Stilken er ganske lige indtil den
øverste Trediedel, men her begynder den svagt at dreie
sig efter Længden, saa at den skedeformige Udvidning er
spiral formigt vreden, Fig. 26.
Rachis er hægerformet, næsten rund og ender i en
saagodtsom fritstaaende Knop, 5""" bred, Fig, 26, a, og
hvor Polyperne tage deres Udspring, er den 95""" i
Omkreds. Den er 35""" høi, ligesaa bred og bærer 35
Polvper.
Ventralfladen er noget langstrakt, lidt konkav i Midten,

The stem measures 1820""" from the base to the
rachis. The bulbous part measures 340""" in length, and
is perfectly round, and almost uniformly thick throughout.
The superior portion alone, is somewhat flattened, and nearly
quadrangular, and measures about 50""" in circumference.
It’s inferior extremity is transversely truncated, and is 55"""
in circumference. The sheath-formed dilation is 130"""
long, and 15""" broad, and closely beset with zooids, which,
lower down on the stem, arrange themselves in series, on
the ventral and dorsal sides. From the bulbous part, the
stem diminishes in thickness, so that, it is 3.5""" thick in
proximity to the sheath-formed dilation. The stem is
quite straight, up to it’s superior third part, but it, there,
begins to twist itself gently, longitudinally, so that the
sheath-formed dilation becomes twisted in spiral form (fig. 26).
The rachis is chalice-formed, and almost round, and
it terminates in a nearly detached knob, which is 5""" broad
(fig. 26. fl) and. at the point where the polyps have their
origin, it’s circumference is 95""". It is 35""" high, and the
same in breadth, and carries 35 polyps.
The ventral surface is somewhat elongate, and a little
concave in the middle; it is broad at the lower
