smalner noget af opad mod den temmelig brede, afstum- 
pede Ende og nedad mod Stilken, Fig. 17. 18. 
Dorsalfladen er lidt hvælvet og paa dens nederste 
Del iagttages Enden af en noget dyb Fure, der strækker 
sig i en Bøining omtrent 20”” langt nedover Stilken, Fig. 
17. Ovenfor denne Fure udspringe Polyperne saaledes, at 
de danne 3 Længderækker. I den midterste Række er 
der 3 Polyper, hvoraf den mellemste staar lidt til Høire. 
Til Venstre sees 2 og til Høire 3 laterale Polyper. Un- 
der den nederste Midtpolyp, lidt til Siden, sees en uud- 
viklet Polyp, og en lignende findes ogsaa under de høire 
Sidepolyper. 
Dorsalfladen er besat med store, konisk fremspin- 
gende Zooider, som paa dens øverste Del staa meget tæt 
sammen, imedens de forøvrigt ere noget spredte og mangle 
ganske paa de aflange Felter, hvor Polyperne udspringe, 
Fig. 17. Disse Felter betegne egentlig den ydre Veg af 
Polypeellen, som er aflang, nedsænket 1 Sarcosomaet og 
skjuler ganske Polypen, naar den er indtrukken og dan- 
ner da en aflang Fremstaaenhed med en stjerneformig 
Aabning paa dens øverste Del. 
Ventralfladen har en dyb, temmelig bred Fure, der 
er nøgen 1 Bunden, hvor Axen skinner igjennem, men er 
til Siderne torsynet med Zooider, Fig. 18. Bugfuren er 
307” lang, ophorer 10”” fra øverste Ende og strækker sig 
langt nedover Stilken. Den er ganske lidet krummet efter 
Længden og dens tykke Rande ere besatte med Zooider, 
Fig. 18. 
Paa hele Ventralfladen sees Zooider, der paa de ne- 
derste */; Dele ere ordnede i 2—3 uregelmæssige Længde- 
rækker langs Bugfuren, imedens de paa den øverste Del 
indtage hele Fladen, Fig. 18, staa meget tæt sammen og 
støde til Dorsalfladen, saa at det øverste Parti af Rachis, 
der er frit for Polyper, faar et stærkt papilløst Udseende, 
Fig. 18. 
Stilken er næsten rund, 44”” lang og ender i en af- 
lang Blære. De paa Rachis beskrevne Furer fortsættes 
nedover Stilken saavel paa Dorsal- som paa Ventralfladen 
indtil omtrent 25”” fra Endeblæren, og paa hver af deres 
Sider sees en Række enkeltstaaende Zooider, der rage kun 
ganske lidet opover Fladen. 
Polyperne er eylindriske, gjennemsigtige, 18—20"” 
Deres Krop er 8—10”” lang med 8 ophøiede Li- 
nier, dannede af Spikler, som ligge pakkede paa hverandre 
i en Længderække og ere 0,357” lange, 0,018”” brede 
samt takkede i begge Ender. Imellem disse Ribber er 
Huden forsynet med lignende Spikler; men her ligge de

whence, it becomes somewhat narrower, upwards, towards 
the rather broad, blunted extremity; and, downwards, tow- 
ards the stem (fig. 17. 18). 
The dorsal surface is a little arched; and on its in- 
ferior part, the extremity of a somewhat deep furrow is 
observed, extending in a curvature, about 20””", down along 
the stem (fig. 17). Above this furrow, the polyps project 
in such a manner, that they form 3 longitudinal series. 
In the middle series, there are 3 polyps, of which, the 
median one, is placed a little to the right. To the left, 
two, and to the right, three, lateral polyps are seen. 
Below the inferior median polyp, and a little to the side, 
an undeveloped polyp is seen, and a similar one is seen 
below the right lateral polyps. 
The dorsal surface is beset, with large, conical, pro- 
tuberant zooids, which upon its superior portion are situ- 
ated very closely together, whilst, elsewhere, they are 
somewhat scattered, and are entirely devoid of the oblong 
areas where the polyps protrude (fig. 17). These areas, 
really, denote the outer wall of the cell of the polyp; 
this is oblong, and depressed in the sarcosoma, and 
quite conceals the polyp, when it is retracted; but it then 
forms an oblong protuberance, with a stellate aperture on 
the upper part. 
The ventral surface has a deep, rather broad furrow, 
which is bare at the bottom, where the axis appears vis- 
ible through it, but is furnished with zooids on it’s sides 
(fig. 18). The ventral furrow is 307" long, and ter- 
minates 10”” from the superior extremity, and extends far 
down the stem. It is quite slightly curved longitudinally ; 
and it’s thick margin is beset with zooids (fig. 18). 
On the entire ventral surface, zooids are seen; which 
on the lower */s'" parts, are arranged in 2—3 irregular, 
longitudinal series along the ventral furrow; whilst, upon 
the upper part, they occupy the whole surface, (fig. 18), 
and are placed very closely, together, and abut upon the 
dorsal surface, so, that the superior portion of the rachis, 
which is devoid of polyps, acquires a prominent papillous 
appearance (fig. 18). 
The stem is almost round, and is 44”” long, and ter- 
minates in. an oblong vesicle. The furrows described as 
pertaining to the rachis, are continued down the stem, both 
along the dorsal and the ventral surface, until about 257" 
from the terminal vesicle; and on each of their sides, a 
series of isolated zooids is seen, which only project a very 
little beyond the surface. 
The polyps are cylindrical and translucent, 18—20"” 
long. Their body is 8—10” long, and has 8 elevated 
lines formed of spiculee, which lie, packed upon each other in 
a longitudinal series, and measure 0.351” long, and 0.018”” 
broad, and are aculeated at both the extremities. Between: 
these ribs, the integument is furnished with similar spic- 
ulæ, but here, they are placed singly, and in a diagonal 
direction. The tentacles are 10—12”” long, and have a 
longitudinal series of large triangular spiculæ, situated in 
the middle of their aboral surface; these are 0.577” long,
