samtlige Polyper havde Mundskiven og Adoralsiden af 
Tentaklerne samme Farve.

Stilken fra Grunden til Rachis er 470”” lane; den 
skedeformige Udvidning er 25”” lang, 6”” bred, hvor den 
gaar over i Rachis. Denne er 15”” lang, 13”” bred. Den 
øverste Del af Stilken tilligemed Rachis er spiralformigt 
dreiet. Den nederste, bulbøse Del er 80”” lang, smalere 
paa Midten (6”” bred) og 8”” bred, baade hvor den opad 
begynder at smalne af og mod den nederste Ende, hvor 
der er en oyoid Skraaflade, der ender i en Spids, Fig.

mærket, hos samtlige Exemplarer, na?r undtages det mind-

Det smaleste Parti af Stilken findes 
op imod den skedeformige Udvidning, hvor den er knapt 
1”” bred. Den bulbøse Del er lidt fladtrykt mod Ventral- 
og Dorsalfladen; den øvrige Del af Stilken, indtil det Sted, 
hvor den skedeformige Udvidning begynder, er rund og

Rachis er bægerformet udvidet til Siderne, bliver 
opad noget smalere, uden at det dog er muligt paa Grund 
af dens stærke Dreining at paavise, hvorledes den ender. 
Dens Ventralflade er konvex og tæt besat med Zooider; 
kun paa dens nederste Del iagttages en smal Midtstribe, 
som er nøgen og glat, og hvor Axen skinner igjennem,

disk was nearly flesh colour; and when this was so, the 
adoral surface of the tentacles, had, also, the same colour. 
In others, the colour was almost yellow; but, in the whole 
of the polyps, the oral disk, and the adoral side of the 
tentacles, were, uniformly, of the same colour.

The stem is 470”” long, from the base to the rachis; 
and the sheath-formed dilation is 25”” long, and 6”” broad, 
at the point where it passes over into the rachis. The 
latter is 15”” long and 13”” broad. The superior portion 
of the stem, and also the rachis, is twisted spirally. The 
inferior bulbous part, is 80”” long, and is narrowest at 
At the 
point above, where it commences to become narrower, it 
measure 8”” in breadth; and it also measures 8”” in breadth,

appears, to contribute in securing the stalk to the clay 
bottom. The narrowest part of the stalk occurs, up towards 
the sheath-formed dilation, at which point it is barely 1””

stem, up to the point where the sheath-formed dilation 
begins, is round, and somewhat longitudinally twisted. 
The rachis is enlarged laterally, in a chalice form, 
and becomes, somewhat narrower, upwards; but it is 
not possible; on account of its sharp twisting; to detect 
where it terminates. It’s ventral surface is convex, and 
closely beset with zooids, and, only, on the inferior part, 
may a narrow mesial stripe, be observed; this is bare, 
and smooth, and through it, the axis appears visible (Pl. VI, 
ke, WA, Øk 
Below, the dorsal surface is slightly concave; but, 
above, it is a little arched; becoming then nearly flat; 
then expanding, greatly, to the sides, producing thus, lateral 
surfaces whieh slope off towards the ventral surface. Both 
the dorsal surface, and the lateral surfaces are closely 
beset with zooids, which prolong themselves to the ventral 
surface, in lancet formed areas, between the polyps. On 
the sheath-formed dilation, there are, also, observed, com- 
pactly situated zooids, both, on the dorsal and ventral 
surface; and the further up the stem that they extend, the 
more dispersed do they become; whilst, they also arrange 
themselves more in series, of which, there are 2 at the 
commencement, and, then, one on each side. The rachis 
carries 17 developed polyps; of these, 2 are very small. 
The terminal polyp originates, just at the point where 
the dorsal surface appears to pass into the ventral surface.
