Ventralsiden er næsten flad, dens midterste Del dan- 
ner et smalt, nøgent Belte, og til hver Side er en regel- 
mæssig Række Zooider, der ligesom begrændser Ventralfladen, 
Fig. 15. Disse Zooider, der rage lidt mere frem end de 
paa Dorsalsiden, staa længere fra hinanden, og hvor de 
støde til Sidecellerne, er der som oftest to ved Siden af 
hinanden, ellers dannes Rækken kun af enkeltstaaende 
Zooider. Imellem enkelte Cellereekker sees Zooiderne 
at udfylde Rummet lige til Ventralrækken. 
Cellerne ere overalt rigt besatte med lange, stavfor- 
mede Spikler, der ere noget forskjellige baade i Længde og 
Bredde, fra 0,560—0,893”” lange og fra 0,020—0,035”” 
brede, Fig. 20; de ere trekantede, tilspidsede 1 begge En- 
der, farvefri og ligge tæt til og paa himanden; i de 
føromtalte Tænder ordne disse Spikler sig pyramideformigt 
imod Tandens Spids. Aldeles lignende Spikler findes i 
Sarcosomaet, der er temmelig tyndt og halvt gjennemsigtigt ; 
kun i det smale, nøgne Belte paa Ventralfladen ligge 
Spiklerne enkeltvis og meget langt fra hverandre og danne 
afbrudte Længderækker; de ere 0,223”” lange, 0,017”” brede 
paa Midten. 
Polyperne ere cylindriske; deres Krop er omtrent 
3”” lang, forsynet med 8 svage Længderibber, der antyde 
Insertionerne for Septa og er uden Kalk. Tentaklerne ere 
fjederformede, lange, omkring 5—6”” og have paa hver

nes aborale Flade sees lige fra Grunden og næsten til 
Side omtrent 20 Pinnuler. 
Spidsen en uafbrudt Række af trekantede, valseformede 
Spikler, Fig. 18, hvoraf de ved Tentakelens Grund og 
Spids ere meget smaa, imedens de øvrige ere fra 0,290—0,318”” 
lange og fra 0,020—0,027”” brede, Fig. 19. 
Zooiderne have en vid, næsten rund Mundaabning, 
Fig. 17, a, og ere omgivne krandsformigt af spindelformede, 
trekantede Spikler, der udgaa vifteformigt fra Grunden, 
ligge paa hverandre og udbrede sig omkring Zooiden, saa at 
denne er vel beskyttet. Disse Spikler ere fra 0,280—0,357”” 
lange og fra 0,020—0;035”” brede, Fig. 17, b. 
Spiklerne ere overalt uden Farve.

Et Exemplar. 
Vestfjorden, syd for Skraaven. 
Lerbund med iblandet Smaasten. 
The ventral surface is almost flat; it’s mesial part 
forms a narrow unoccupied stripe, and on each of the 
sides, there is a regular series of zooids, which, as it were. 
defines the ventral surface (fig. 15). . These zooids protrude 
a little more forward than those of the dorsal side, and 
are situated further apart from each other, whilst, also, at 
the point where they abut on the lateral cells, there are, 
usually, two of them placed alongside each other, but other- 
wise, the series is solely composed of solitary zooids. Between 
a few of the cellular series, the zooids are seen to occupy 
the space right up to the ventral series. 
The cells are, everywhere, richly beset with long, 
rod-like spicules, which vary somewhat, both, in length 
and breadth, measuring from 0.560—0.893”” long, and 
trom 0.020—0.035”" broad (fig. 20). They are triangular, 
acuminated at both extremities, and colourless, and they

pyramidal form towards the point of the tooth. 
thin and semi-transparent. Only in the narrow, unoccupied 
stripe on the ventral surface, do the spicules appear, singly, 
at long intervals from each other, and form imterrupted 
longitudinal series. They measure 0.223”” in length, and 
0.017”” in breadth at the middle. 
The polyps are cylindrical; their body is about 3” 
long, and is furnished with 8 delicate longitudinal ribs, 
which denote the insertions for the septa, and are devoid 
of calcium. The tentacles are feather-shaped, and about 
5—6”” long, and they have about 20 pinnules on each 
side. In the mesial part of the aboral surface of the ten: 
tacles, there is seen, extending right from the base and 
almost to the pomt, a continuous series of triangular, 
roller-formed spicules (fig. 18), of which, those situated at 
the base, and poimt of the tentacles, are very small, 
whilst, the others, are from 0.290—0.318"” long, and from 
0.020—0.027”” broad (fig. 19). 
The zooids have a wide, almost round oral aperture 
(fig. 17, a@,), and are surrounded in wreath form, by fusi- 
form triangular spicules, which issue from the base in 
a fan-shape, lie upon each other, and spread themselves 
around the zooid, so that it is well protected. These spic- 
ules are from 0.280—0.357”” long, and from 0.020—0.035”” 
broad (fig. 17,0). 
The spicules are, everywhere, colourless. 
Colour. 
The rachis is faint yellowish-red. The polyp-cells are, 
at their base, a beautiful brick-red colour. The polyps are 
clear as water, and the tentacles are the same.
