Del er hvid, deres Rand forsynet med hvide Spieler. 

 Forøvrigt er ogsaa Farven forskj eilig. 



Findested Askevold i Søndfjord paa 30—50 Favne. 

 Vi have kun havt 2 Exemplarer, hvoraf det største, som 

 ovenfor er beskrevet, var fuldvoxent; Bladene indeholdt 

 en Mængde Æg. Det andet var et ganske ungt Exempl., 

 og meget beskadiget i nederste Ende. 



PENNATULA D1STORTA, Nob. 

 (Tab. 11, Fig. 10, 11). 



Stokken temmelig rank, bredest paa Midten al den 

 polypbærende Del, smalere nedad, hvor den ender i en 

 conisk Spids, der i levende Live kan antage Kugleformen. 



Ventralfladen er forsynet med en Længdefure, paa 

 hvis Sider sees en Mængde Zooider ganske lig dem paa 

 Pennatula phosphorea, L. 



Dorsalfladen har ligeledes en Længdefure ; paa begge 

 Sider af denne 2 — 3 Rækker Zooider, der tildels afbrydes 

 af Bladinsertionerne. 



Bladene ere lange, småle, dreiede 3—4 Gange om 

 sin Længdeaxe og forsynede med 5—7 Polyper. 



Cellerne ere lange, sidde meget spredte, og paa 

 Grund af Bladets Dreining indtage de ikke en enkelt Rad, 

 saaledes som paa P. phosphorea, men staa afvexlende. 



Axen er temmelig tynd, næsten traadformig opad, 

 hvor den ender i en liden Anse noget over Midten af 

 Rachis. Nedad bliver den tykkere og gaar næsten lige 

 nedtil Spidsen af Stilken, hvor den ender i en mindst 

 dobbelt saa stor Anse, som foroven. 



Farven: Rachis mørkerød; Stilken bleg gulrød. 

 Bladene mørkerøde med blegrøde Spikelrækker efter 

 Længden. Cellerne ligeledes mørkerøde, den øverste Del 

 blegrød, Randen er forsynet med 8 fremragende næsten 

 hvide Spicier. 



Polyperne have saavel paa Tentaklerne, som paa 

 deres Traade, blegrøde Spicier.

 emplarer og i Stockholms 1.

and bearing more polyps; 4. by the upper part of the 

 cells being white, the margin furnished with white spicula. 

 Moreover the color is in other respects different. 



It is found at Askevold in Søndfjord 30 — 50 fathoms. 

 We have only had 2 specimens, of which the largest, 

 above described, was full grown. The leaves contained 

 a great many eggs. The other was a quite young spe- 

 cimen, and somewhat damaged at the lower extremity. 



PENNATULA D1STOBTA, Nob. 

 (Tab. 11, fig. 10, 11). 



The polypary rather slender, wider in the middle of 

 the polypiferous part, narrower downwards where it ter- 

 minates in a conical point, which during life may take a 

 globular form. 



On the ventral surface is a longitudinal furrow, on 

 the sides of which appear a number of zooids quite like 

 those of Pennatula phosphorea, L. 



The dorsal surface has also a longitudinal furrow, 

 and on both sides of it 2-— 3 rows of zooids, which are 

 partly interrupted by the insertions of the leaves. 



The leaves are long, narrow, turned 3 — 4 times round 

 the longitudinal axis, and bear 5 — 7 polyps. 



The cells are long, far apart and by reason of the 

 twisting of the leaves do not occupy a single row, as in 

 Penn. phosph., but stand alternately. 



The axis is rather thin, nearly filiform in the upward 

 direction, in which it ends in a small bend somewhat 

 above the middle of the rachis. In the downward direc- 

 tion it becomes thicker and goes nearly down to the 

 point of the stalk, where it terminates in a bend at least 

 double the size of that at the upper extremity. 



Color: rachis, dark-red; the stalk pale yellow-red; 

 the leaves dark-red with pale red rows of spicula run- 

 ning longitudinally; the cells likewise dark-red; the 

 upper part pale red, where the margin is furnished with 

 8 prominent, nearly white spicula. 



The polyps have, as well on their tentacles as on 

 their filaments, pale red spicula. 



It is found at Askevold in Söndfjord at a depth of 

 40—50 fathoms. In the museum at Christiania we have 

 seen 2 specimens and in the museum at Stockholm 1.

Pennatula distorta is characterised by its long narrow 

 fins twisted round its own axis, and by the small number 

 of cells 5 — 7 situated alternately on the fins.
