selve Spidsen, hvilket dog ikke er Tilfældet, thi den tager sit
Udspring lidt under denne paa Dorsalfladen, Fig. 6, a*. 7, b.
Polypkroppen er 8""" lang, 2""" bred; Tentaklerne 9mm lange.
Paa hver Side, strax nedenfor (under) Endepolypen, paa
Dorsalfladen udspringe 2 Polyper, hvoraf de til høire Side,
Fig. 6, b, b. 7, c, c, ere 14""" lange, 3""" brede, med 14"""
lange Tentakler; de til venstre, Fig. 6, c, c. 7, d, d, ere
11—12""" lange, Tentaklerne 14""". Tæt under
Endepolypen, omtrent paa Midten af Dorsalfladen, staar 2 Polyper,
af hvilke den nederste er 6"’m lang, 1’""’ bred, med 7"""
lange Tentakler, Fig. 6, d, imedens den øverste, nærmest
Endepolypen, er 5""" lang, med 7"’"’ lange Tentakler, Fig.
li, e. 7, /.
Alle Polyper have en cylindrisk, glat Krop, paa hvis
udvendige Flade sees 8 hvide Linier, som ere
Insertions-stederne for Septa. Igjennem Kropshuden sees det lange,
stærkt foldede Svælg. Mundskiven er hvælvet, og i dens
Midte er Mundaabningen, der danner en Tverspalte med
8 lancetformede Læber.
Tentaklerne ere næsten cylindriske, paa den adorale
Flade tæt besat med yderst fine Papiller og forsynede
paa hver Rand med koniske Pinnuler, der staa
uregelmæssigt over for hverandre og have forskjellig Størrelse,
saaledes at imellem to store staa sædvanligvis 1, stundom 2
meget smaa.
Axen er som hos No. 1.
ceeded from the point itself; but that is, however, not the
case, becanse it originates a little below the point, on the dorsal
surface (figs. 6, a*. 7, b). The body of the polyp is 8""" long,
and 2’""’ broad, and the tentacles are 9""" long. On each sidt;,
immediately below (underneath) the terminal polyp on the
dorsal surface; 2 polyps proceed, of which, those to the
right side (figs. 6, b, b. 7, c, c), are 14""" long, and 3"""
broad, with 14""" long tentacles; and those to the left
side, (fig. 6, c, c. 7, d, d) are 11—12""" long, with 14"""
long tentacles. Close under tin* terminal polyp, and about
the middle of the dorsal surface; 2 polyps are situated,
of which, the lower one is 6’""’ long, and lmm broad, with
7""" long tentacles (fig. 6, d)\ whilst the other, upper one,
next the terminal polyp, is 5""" long, with t’"" long tentacles
(figs. 6, e. 7, /).
All the polyps, have a cylindric, smooth body; on
the exterior surface of which, 8 white lines are visible;
these are the points of insertion for septa. Through the
integument of the body, the long, numerously folded gullet
is seen. The oral disk is arched; and in its middle; the
oral aperture occurs, and forms a transverse fissure,
having 8 lancet formed labiæ.
The tentacles are nearly cylindric; and on the adoral
surface, are closely beset with extremely minute papilla»;
and are furnished on each margin, with conical pinnules,
situated irregularly, opposite each other; these are of varying
size, so that in general, between two large, 1, and
occasionally 2, very small ones, are placed.
The axis is like that of No. 1 specimen.

Stilken, der paa den øverste Trediedel er næsten
S-formigt bøiet, har en Længde af 160""" fra den nederste
Ende til Rachis. Den nederste, bulbøse Del, som er
noget fladtrykt, paa Ventral- og Dorsalfladen, er 48""" lang,
noget indkneben paa Midten, 4""" bred foroven, og dens
nederste Ende danner en ægformet Skraat!ade, der løber ud
i en Spids, Fig. 8; — hverken paa denne eller Skraafladen
opdagedes nogen Pore. Stilkens øverste Del er stærkt
krummet og skedeformigt udvidet imod Rachis. Denne
Udvid-ning er 7mm lang, 2,5’""’ bred øverst oppe, hvor der sees
endel Zooider.
Rachis er stærkt, næsten S-formigt bøiet efter
Længden, noget dreiet til Siden, 8""" lang, 4’""’ bred, og har en
afrundet, fri Ende, Fig. 9, a. Ventralfladen er konvex og
krummet S-formigt; paa Midten af dens nederste Del,
deier glat og nøgen, skinner Axen igjennem, imedens den
øverste. Del og Siderne ere tæt besatte med Zooider, Fig.
9, b. Dorsalfladen er omtrent halvt saa lang som Ventral-
No. 3 specimen.

The stem is curved oil the superior third part, in
nearly S-form; and, its length is 160’""1 from the inferior
extremity to the rachis. The inferior bulbous part; which
is somewhat flattened on the ventral and dorsal surface,
is 48""" long; is somewhat constricted at the middle; and is
4""" broad above. It’s inferior extremity forms an ovate
sloping surface, which projects in a point (Pl. V, fig. 8).
Neither upon it, nor on the sloping surface, were any
pores detected. The superior part of the stem is strongly
bent; and is dilated in sheath-form, towards the rachis.
This dilation is 7m"’ long, and 2.5""" broad, at the
superior termination; at which point, a number of zooids are
visible.
The rachis is strongly bent, longitudinally; nearly in
S-form; and is somewhat twisted laterally. It is 8",m
long, and 4’""’ broad, and has a rounded free extremity
(Pl. V, fig. 9, a). The ventral surface is convex, and bent
in the form of an S. In the middle of its inferior part;
which is smooth, and bare; the axis appears visible;
whilst, the superior part, and the sides, are closely beset
