hvor den gaar over i Rachis og er stærkt dreiet, Fig. 27, a, 
overalt tæt besat med Zooider, der nedover Stilken samle 
sig i Rækker paa Ventral- og Dorsalfladen, men blive alt 
sparsommere og sparsommere, saa at de paa den bulbøse 
Del staa ganske enkeltvis. 
Rachis er bægerformet, rund og saa fordreiet, at det 
ikke er muligt at se, hvor den ender. Den er 1107” i 
Omkreds, 23”” hoi, 32”” bred og bærer 26 Polyper, som 
indtage saavel Dorsal- som Ventralfladen, der egentlig er 
imaginær; thi Rachis danner en opad stærkt udvidet Klump, 
hvorpaa Polyperne sidde tilsyneladende i Kredse, den ene 
indenfor den anden. Imidlertid kan Polyperne lægges saa- 
ledes ud fra hverandre, at en bilateral Symetri kan frem- 
stilles; men den bliver jo altid ufuldkommen og maa kun 
betragtes som Rester af en fordums saadan. 
Omtrent paa Midten af den næsten horizontalt lig- 
gende Rygside staa 3 Polyper i Rad, hvoraf den forreste, 
Fig. 27, 1*, er Terminalpolypen, hvis Krop er 25”” lang og 
gr” bred ved Grunden; Tentaklerne 45”” lange; den anden 
er lidt større, Fig. 27, 1; men den tredie, bagerste, er den 
største; dens Krop er 35”” lang, 107” bred; Tentaklerne 
45” lange. Denne Række danner de central-dorsale Po- 
lyper, ihvorvel de ere skudte noget til Siden paa Grund 
af Fordreimingen af Rachis. 
Til venstre Side af Centralpolyperne staa 3 omtrent 
lige lange Polyper i en lidt skjæv Række, Fig. 27, 2, 2, 2; 
Kroppen er 35”” lang, 7”” bred; Tentaklerne 40”” lange. 
Den forreste af disse 3 dorsal-laterale Polyper udspringer 
egentlig fra Ventralfladen. Udenfor dem sees 5, omtrent 
lige store Polyper, der staa i en Halvkreds og maa be- 
tragtes som de egentlige laterale Polyper, Fig. 27, 3, 3, 3, 3, 3; 
Kroppen er 50”” Jang, 107” bred; Tentaklerne 65”” lange. 
Til høire Side, der er større end venstre, staa ved 
Siden af Centralpolyperne 4 lige store Polyper i en næsten 
lige Linie; Kroppen er 35”” lang, 7”” bred; Tentaklerne 
45”” lange, Fig. 27, 4, 4, 4, 4; udenfor dem staa atter 4 
lige store Polyper 1 en lidt skjæv Række, Fig. 27,5, 5, 5, 
5; Kroppen 33”” lang, 7”” bred; Tentaklerne 40”” lange. 
Til Siden af disse staa 2 Polyper, Fig. 27, 6, 6, af hvilke 
den ene er lige stor som de sidst omtalte 4, imedens den 
anden, der staar ganske nær den yderste Række, er kun 
227” lang, 4”” bred med 25”” lange Tentakler. Disse 10 
Polyper, som repræsentere de dorsal-laterale, omgives af 5 
store, laterale Polyper, Fig. 27, 7, 7, 7, 7, 7, stillede i en 
Halvkreds, der slutter sig ganske til de laterale Polyper 
paa venstre Side, hvorved den ydre Polypkreds dannes, 
som kun paa Ventralfladen er yderst lidt afbrudt, Fig. 27, 0. 
Af alle de tidligere beskrevne Former er der ingen, 
broad at the point where it passes over into the rachis, 
and it is strongly twisted (fig. 27, a). It is, everywhere, 
closely beset with zooids, which, down along the stem, are 
collected in series on the ventral and dorsal surfaces, but 
they become more and more sparingly placed, so that, finally, 
on the bulbous part, they are placed quite singly. 
The rachis is chalice-formed, and round, and is so 
much twisted, that it is impossible to detect where it ter- 
minates. It is 110”” in circumference, and 23" high; it’s 
breadth is 327; 
p) 
both the dorsal and ventral surfaces; the latter surface 
and it carries 26 polyps, which occupy 
is, however, only imaginary, becanse, the rachis forms an 
upwards, strongly-dilated lump, upon which the polyps, 
apparently, are seated in rings, the one inside the other. 
But, the polyps may, however, be separated apart from 
each other, and a bilateral arrangement thus presented; it 
is, however, always incomplete, and can only be considered, 
as the remains of an earlier bilateral arrangement. 
At about the middle of the nearly horizontally placed 
dorsal side, 3 polyps are placed in a series, of which, the 
anterior one (fig. 27, 1*), is the terminal polyp; the body 
of this one, is 25”” long, and 9”” broad at the base, and it's 
tentacles are 45”” in length. The second polyp is a little 
larger (fig. 27, 1); but the third (posterior) one is the 
largest. It’s body is 35”” long and 10”” broad, and the 
tentacles are 45”” long. his series forms the centro- 
dorsal polyps, although, they are somewhat pushed aside 
in consequence of the twisting of the rachis. 
To the left side of the central polyps, 3 nearly uni- 
formly long polyps are placed in a somewhat crooked 
Their body is 35”” long, and the 
The 
anterior one of these dorso-lateral polyps, originates, really, 
in the ventral surface. 
Series (fig. 27, 25 2. 2) 
breadth is 7””, whilst the tentacles are 40”” long. 
Outside these, 5 nearly uniformly 
large polyps are observed, situated in a semicircle, and may 
be considered to be, the real lateral polyps (fig. 27, 3, 3,3, 3,3). 
Their body is 50”” long, and 10”” broad, and the ten- 
tacles are 65”” long. 
On the right side; which is larger than the left one; 
4 polyps of uniform size are situated in an almost straight 
line, alongside the central polyps. Their body is 35”" 
long and 7”” broad, and the tentacles are 45”” long (fig. 
27, 4, 4, 4, 4). Outside these, there is placed, still 
other 4 polyps of uniform size, in a slightly crooked series 
(ie, 21, 5, 5, 5 wD), Wnewe looky ms 887 mg, amd (2 
broad, and the tentacles are 40”” long; and alongside of 
these, again, 2 polyps are situated (fig. 27, 6, 6), of which, 
the one is similar in size to the 4 polyps last spoken of, 
whilst, the other, which is placed near the outer series, is 
only 22”” long, and 4”” broad, with tentacles 25”” long. 
These 10 polyps, which represent the dorso-lateral polyps, 
are surrounded by 5 large lateral polyps (fig. 27, 7, 7, 7,7, 7) 
placed in a semicircle, and which quite unite with the lateral 
polyps on the left side, andin this manner, the outer polyp- 
ring is formed; which, upon the ventral surface alone, is 
extremely little interrupted (fig. 27, 0). 
Of all the previously described forms, there is none,
