aftager den successivt, er næsten ganske rund, saa at den 
op imod den skedeformige Udvidning er knap 8””" bred. 
Fra den stærke Udvidning paa den bulbøse Del begynder 
Stilkens spiralformige Dreining, der fortsættes gjennem hele 
Længden, en Dreining, der især er stærkt fremtrædende 
paa Spiritusexemplaret. Den skedeformige Udvidning er 
spiraldreiet, Fig. 25, a, 150"" lang, 20”” bred, hvor den 
gaar over i Rachis; den er overalt tæt besat med Zooider, 
der sidde mere spredte, jo længere de komme ned paa 
Stilken. Ogsaa paa den øverste Del af det bulbøse Parti 
sees lignende Zooider. 
Rachis er bægerformet, næsten rund, Fig. 25, b, 38”” 
hoi, dens øverste Omkreds 150””. Bredden omtrent 48””. 
Ventralfladen er kort, lidt fladtrykt, tæt besat med Zooider. 
Dorsalfladen smelter saagodtsom sammen med Lateralfla- 
derne, og samtlige ere overalt optagne af Zooider, som 
danne lancetformige Felter imellem Polyperne, der tilsyne- 
ladende staa i Kredse rundt Rachis, men som ved ngiere 
Granskning vise tydelig Spor af en bilateral Stilling. 
Terminalpolypen er 30”” lang, 8”” tyk ved Grunden; 
Tentaklerne ere 35”” lange, Fig. 25, 1*. Omtrent et Par 
Mm. nedenfor og bagenfor 1 lige Linie sees en Polyp, hvis 
Krop er 35”” lang, 8”” tyk ved Basis og med 40”” lange 
Tentakler, Fig. 25, 1; i samme Afstand fra denne findes 
en tredie Polyp af omtrent samme Størrelse som den fore- 
gaaende, Fig. 25, 1. Disse 3 Polyper kunne betragtes som 
de central-dorsale Polyper, idet de udgaa fra Midten af 
den næsten horizontaltliggende, brede Rygflade. Omkring 
dem gruppere sig 28 større og mindre Polyper saaledes, 
at tilhøre er 15 og tilvenstre 13, dersom man tænker sig 
Rachis inddelt i 1 Centraldel og 2 Sidedele. 
Omtrent et Par Mm. tilhøire af de 3 Centralpolyper 
staar i en liden Bue 4 Polyper, Fig. 25, 2, 2, 2, 2, der 
ere næsten lige store; deres Krop er 35”” lang, 10”” tyk 
ved Grunden, og Tentaklerne ere 45"” lange; udenfor og til 
Siden af disse er 5 Polyper, hvoraf de 4 danne en svagt krum- 
met Linie, imedens den 5te staar for sig selv, Fig. 25, 3, 
3, 3, 3, 3; de have den samme Størrelse som de fore- 
gaaende 4, og endelig kommer den yderste Række, be- 
staaende af 6 store Polyper, som alle ere næsten af samme 
Størrelse; Kroppen er 45”” lang, 16”” bred ved Grunden 
og Tentaklerne 35”" lange, Fig. 25, 4, 4, 4, 4, 4, 4. 
Et Par Mm. tilvenstre at de 3 Centralpolyper staa i 
en lidt krummet Række 3 Polyper, hvis Krop er 30”” lang, 
10”” tyk, Tentaklerne 35”” lange, Fig. 25, 5, 5, 5. Uden- 
for disse sees 2 Polyper af samme Størrelse som de nys- 
nevnte 3, Fig. 25, 6, 6, og udenfor dem findes atter 2 
Polyper, hvis Krop er 35”" lang, 10”” tyk, Tentaklerne 
40”" lange, Fig. 25, 7, 7. Udenom disse 7 Polyper staar 
thickness, upwards, until, it rather abruptly, becomes 
enlarged and attains a circumference of 100". It sub- 
sequently diminishes, gradually, and becomes nearly round, 
so that, up towards the sheath-formed dilation, it is barely 
8”" broad. The spiral twisting of the stem commences, 
at the large dilation of the bulbous part, and continnes 
through its entire length: —a twisting, which is especially 
prominent in the specimen preserved in alcohol. The sheath 
formed dilation is spirally twisted (fig. 25, a), and is 
150”” long, and 20””" broad at the point where it passes 
over into the rachis. It is, everywhere, closely beset with 
zooids, which however, become more dispersed, the further 
down the stem they are situated. On the superior part of 
the bulbous portion, similar zooids are also seen... 
The rachis is chalice-formed, and nearly round (fig. 
25, b). It is 38”” high, and 150"" in circumference at 
the upper part. The breadth is about 48”". The ventral 
surface is short, somewhat flattened, and closely beset with 
zooids. The dorsal surface becomes, almost fused into the 
lateral surfaces, and, all of them are, everywhere, occupied 
by zooids forming lanceolate areas between the polyps, 
which, apparently, are situated in rings around the rachis, 
but, upon closer inspection, show distinct signs of a bilat- 
eral arrangement. 
The terminal polyp is 30”” long, and 8”" thick at 
the base, and the tentacles are 35”” long (fig. 25, 1*). About 
a couple of milimetres below and behind; in a straight 
line; a polyp is observed, whose body is 35"” long, and 
8”" thick at the base, and its tentacles 40”” in length 
(fig. 25, 1). At a similar distance from that polyp, a third 
polyp is observed, of about the same size as the previous 
one (fig. 25, 1). These 3 polyps may be considered, as 
the centro-dorsal polyps, because, they proceed from the 
middle of the nearly horizontal, broad, dorsal surface. 
Round about them; 28, larger or smaller polyps, are group- 
ed in such manner, that there are 15 polyps to the right, 
and 13 polyps to the left, if we suppose the rachis sub- 
divided, into a céntral portion, and 2 lateral portions. 
About a couple of millimetres to the right of the 3 central 
polyps; 4 polyps are seen, situated in a small are (fig. 25, 2, 
2,2,2). These aré nearly uniform in size, and their body is 
35” long, and 10”” thick at the base, and the tentacles 49”” 
in length. Outside of these, and to the side, there are 5 
polyps; 4 of which, form a gently curved line, whilst the

the same size as the previously mentioned 4 polyps; and, 
fimally, we have the exterior series, consisting of 6 large 
polyps that are nearly uniform in size. The body of 
these polyps is 45”” long, and 16”” broad at the base, 
and the tentacles have a length of 35”” (fig. 25, 4, 4, 4, 4, 4, 4). 
A couple of millimetres to the left of the 3 central 
polyps; 3 other polyps are situated, in a slightly curved 
series. Their body is 30”" long, and 10”” thick, and the 
tentacles have a length of 35"” (fig. 25, 5, 5, 5). Onut- 
side of these; 2 polyps of similar size as the 3 polyps just 
spoken of, are seen (fig. 25, 6, 6), and, outside of them, 
still other 2 polyps are found, whose bodies measure,
