Stilken fra Grunddelen til Rachis 1560”” lang. Den 
bulbøse Del er tenformig og ender i en stump Spidsj; dens 
nedre Del er næsten rund, omtrent 50”” i Omkreds, imedens 
den øvre, mere udvidede Del er noget fladtrykt paa Ven- 
tral- og Dorsalfladen og 60”” 1 Omkreds. Fra denne øvre 
Udvidning aftager Stilken successivt, indtil den imdtager 
kun 3”” i Bredde op imod den skedeformige Del. Denne 
er 12”” bred, hvor den gaar over 1 Rachis og tæt besat 
med Zooider, der strække sig nedover Stilken, hvor de paa 
Ventral- og Dorsalfladen ordne sig til Rækker lige ned til 
den runde Del af Bulbus. Paa dette Exemplar er Stilken 
aldeles ikke dreiet, førend op imod Rachis, hvor den i 
Forening med denne gjør en S-formig Boining, Fig. 24. 
Rachis er bægerformet, næsten rund, kun lidt fladtrykt 
paa Ventralfladen og har en Omkreds af 90"", Fig. 24, a, 
den er 26”” hoi, 30”” bred, lidt hvælvet nedenfra opad

Rygsiden er tæt besat med Zooider, som danne lancetfor- 
mige Felter ind imellem Polyperne, der indtage en næsten 
lignende Stilling som paa No.j8 med Undtagelse af, at 
Ventralfladen her er nøgen, det vil sige uden Polyper. 
Ligesom paa de foregaaende er her 3 Centralpolyper, 
der indtage Midtpartiet af Rygsiden,'og hvoraf Endepolypen, 
som sædvanligt, er den mindste. 
Terminalpolypen danner Grændsen foroven imellem 
Ventral- og Dorsalfladen; den er 16”” lang, 5”” bred med 
25”” lange Tentakler, Fig. 24, 1*. _ De to bagenfor (neden-

lange, 5”” brede; Tentaklerne lige lange som Kroppen. 
De centrale Dorsalpolyper staa 1—2”” fra hinannen, fig.

No. 9 specimen. 
Pl. VII, fig. 24. 
The stem measures 1560”” in length from the basal 
part to the rachis. The bulbous part is spindle-formed, 
and terminates in a blunt point. It’s inferior portion is 
almost round, and is about 50”” in circumference; whilst 
the superior, more dilated portion, is somewhat flattened 
on the ventral and dorsal surfaces, and is 60”” in circum- 
ference. From the superior dilation, the stem diminishes, 
gradually, in breadth, until, in proximity to the .sheath 
formed portion, it is only 3”” broad. The sheath-formed 
part is 12”” broad at the point where is passes into the 
rachis; and is, closely, beset with zooids, which extend 
themselves down along the stem, where they arrange them- 
selves in series, on the ventral and dorsal surfaces right 
down to the round part of the bulb. In this specimen, the 
stem is not at all twisted until in proximity to the rachis, 
and then, in conjunction with the rachis, it forms an S 
formed curve (fig. 24). 
The rachis is chalice-formed, nearly round, and only 
a little flattened on the ventral surface, and it has a cir- 
cumference of 90”” (fig. 24, a). Itis 26”" high, and 30””" 
broad, and is a little arched from below, upwards, but 
more flattened in the middle, and it also carries 28 polyps. 
The ventral surface is 10”” broad at the broadest part, 
but diminishes in breadth, upwards, so that, up towards 
the terminal polyp, it is only about 5”” broad (fig. 24, b). 
The dorsal surface is broad, and may be subdivided into 
a central portion, and two, somewhat diagonally sloping, 
The whole of the dorsal side is, closely, 
forming lanceolate areas between the 
polyps; similar arrangement as in 
No. 8 specimen, with the exception, that in this spec- 
imen,.the ventral surface is bare, that is to say, is devoid 
of polyps. 
Just as in the previous specimen, there are im this 
lateral surfaces. 
beset with zooids, 
assuming a nearly 
one, 3 central polyps occupying the middle portion of the 
dorsal side, and, of these, the terminal polyp, as is usually 
the case, is the smallest one. 
The terminal polyp forms the superior margin be- 
tween the ventral and dorsal surface. It is 16””" long, and 
5” broad, and the tentacles are 25”” in length (fig. 
24, 1*). The two posterior (below) polyps, situated in 
the mesial line of the dorsal side, are 25”” long, and 
5” broad, and the tentacles are of the same length 
as the body. The centro-dorsal polyps, are situated 
at intervals of 1—2”" apart from each other (fig. 24. 1, 
1). Alongside of these, to the left hand, 3 polyps appear, 
situated in a slightly curved series (fig. 24, 2, 2, 2),
