Farven er omtrent som paa No. 8. Hele Polypstok- 
ken har som sædvanligt et temmeligt tykt, gelatinost Over- 
trek, der let gaar «af ved Berørelse, og hvorved Overhuden 
drages med. Den nederste (bulbøse) Del har en lys, ha- 
vannabrun Farve, den øvrige Del er meget lysere brungul. 
Hvor det gelatinøse Overtræk med Overhuden var borte, 
var Sareosomaets 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 om- 
trent af samme Farve som Pinnulerne.

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”” 1 Omkreds. Den skedeformige 
Udvidning er 180”” lang, 15”” bred, tæt besat med Zooider, 
der længere ned paa Stilken ordne sig i Rækker paa Ven- 
tral- og Dorsalsiden. Fra den bulbøse Del aftager Stilken 
i Tykkelse, saa at den op imod den skedeformige Udvid- 
ning 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 
spiralformigt vreden, Fig. 26. 
Rachis er bægerformet, næsten rund og ender i en 
saagodtsom fritstaaende Knop, 5”" bred, Fig, 26, a, og 
hvor Polyperne tage deres Udspring, er den 95”" i Om- 
kreds. Den er 35”” hoi, ligesaa bred og bærer 35

expanding somewhat, in proximity to the tentacular mar- 
gin. On the exterior surface of the body, 8 longitudinal 
lines for the insertions of septa are observed. The in- 
tegument 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 spec- 
The entire stalk of the polyp has, 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 brow- 
nish-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 thin- 
ner, and has a light yellow-brown colour. The polyps are 
The pinnules are somewhat 
lighter in colour, whilst, the oral disk is darker. The 
labiæ of the oral aperture are of nearly the same colour

Pl. VIII, fig. 26: 
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 3.57” 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 im 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, a) 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 12”” broad at the lower
