der ere af forskjellig Størrelse og staa uregelmæssigt over 
for hverandre. Imellem de store Pinnuler er der sædvanlig 
1 liden, stundom ?. Antallet varierer efter Tentakelens 
Længde; paa Tentakler, der ere 25—30”” lange, talte 
man 24—36 store Pinnuler paa hver Side og omtrent 20 
smaa. — Øyerst paa Tentaklerne kunne flere smaa Pin- 
nuler star sammen. Saavel Pinnulerne som Tentakelens

Axen er firkantet med 4 dybe Furer og 4 afrundede 
Kanter; den strækker sig helt igjennem Stokken, hvor den

saaledes, at den yderste, traadformige Ende synes at

Zooiderne indtage ikke alene Rachis men strække

sig nedover den skedeformige Udvidning af Stilken, hvor 
de paa Ventralfladen optage især Sidedelene og lader det 
midterste Parti være frit, imedens de paa Dorsalfladen sees 
overalt, dog temmelig spredt paa den nederste Del, Fig.

sine Detailler. 
Paa Spiritusexemplarer er Stilken mere eller mindre 
firkantet, idet Coenenchymet er faldt sammen og slutter 
sig tæt til den firkantede Axe; men 1 levende Live, hvor 
Coenenchymet es udfyldt af Væsker, og hvor de 4 Længde- 
kanaler ere udspændte af det i dem cirkulerende Fluidum, 
er Stilken rund, naar undtages den nederste, bulbøse Del, 
hvor den er lidt fladtrykt mod Ventral- og Dorsaltladen. 
Farven er den samme som paa de mindre Exempla-

mørkere. Polyperne ere brune. Tentaklerne ere paa den 
aborale Flade lidt lysere end Kroppen, imedens den ado-

Forøvrigt varierer Farven noget hos de forskjellige Poly- 
per paa samme Stok, hvilket tildels afhænger af Udvik- 
lingsgraden. Paa enkelte Polyper var Mundskiven næsten 
ogsaa er 
kjødrød, og da havde ogsaa Tentaklernes adorale Flade 
cylindric, somewhat flattened on the inferior half portion 
of the adoral surface, and, furnished on each margin, 
with conical, accuminate, round pinnules, of varying size, 
situated irregularly, opposite to each other. Between the 
large pinnules; there is, usually, a small one, and, oc- 
casionally, 2 small ones. The number of these varies, 
according to the length of the tentacles. On each side 
of such tentacles as measure 25—30”” long, 24—36 long

pinnules and the tentacles, are closely beset with extremely

The oral 
at which 
point, the oblong, oral aperture, has 8 lancet-formed lab- 
iæ; one, in each oral wall, and, three, on each margin; the 
centre, 
latter of which, have a longitudinal furrow in the middle 
of their inner surface (Pl. IX, fig. 44). 
The axis is quadrangular, with 4 deep grooves, and 
4 rounded edges. It extends along the entire stem, mak- 
ing the same curves as are described under No. I spec- 
imen; but, im such manner, that the outermost, filiform 
extremity, appears to pass into the ventral canal. 
The zooids occupy, not only the rachis, but extend 
themselves down the dilation of the 
stem, occupying, especially, the lateral parts of the ventral 
over sheath-formed 
surface, but leaving the middle part free, whilst, on the 
dorsal surface, they are everywhere visible, although rather 
dispersed on the lower part (Pl. VII, fig. 20%. Further 
down the stem, they become still more dispersed, and are 
situated, partly, in a series on each side. As the struc- 
ture of the zooids is, although quite peculiar, similar in 
all the specimens, it will be subsequently described in all 
its details. 
In specimens preserved in alcohol, the stem is more 
or less quadrangular, because the sarcosoma is shrunk 
together, and closes tight upon the quadrangular axis; 
but, in the living state, when the sarcosoma is filled with 
secretions, and when the 4 longitudinal ducts are expanded 
by the fluid circulating in them, the stem is round; with 
exception of the inferior bulbous part; where, it becomes 
a little flattened towards the ventral and dorsal surface. 
The colour is the same as in the smaller specimens, 
but it appears more intense in this specimen. The infer- 
ior bulbous part, is brown Havana colour; the superior 
part of the stem is yellow, but, on the sheath-formed dil- 
ation, 1t assumes a very light brown colour, which becomes 
somewhat darker on the rachis. 
On the aboral surface, the tentacles are a little lighter in 
colour than the body; whilst, the adoral side, on the con-

trary, is almost chestnut brown, which, is, also, the case 
with the oral disk; but, the oral labiæ are lighter in col- 
our. The colour varies, however, somewhat, in the various 
polyps on the same stalk, being, in a measure, dependent 
on the stage of development.
