of calyx are of the same type, 0,72 mm., spicules of the upper polyp part 0,3-—0,47 mm. 
in length. 
1883 Clavularia arctica Kor. and DAN. 
The specimen is characterized by its large polyps, and by the high, well-developed 
calyx, which occupies more than one half, or 7/,, of the whole polyp. Spicules in the 
stolon and calyx are large, powerful spindles, respectively 0,5 and 0,72 mm. in length, with 
long thorns, very closely packed. (Fig. 8 c.) The few spicules of the apper polyp-part 
are 0,3—0,47 mm. long spindles and rods, slighltly thorned. (Fig. 8 e.) For other details 
I refer to BrRocH 1912, as my own investigations only confirm these of BRocH. 
General Distribution: 
Norway, Hardanger Fiord, Varanger Fiord, 55—300 met. BrocHu 1912 e). 
Clavularia stormi KoREN and DANIELSEN 1883. 
Diagnosis: Creeping, narrow stolons. The polyps are 3 mm. in length, with 2,5 mm. 
high calyx. Stolon spicules 0,25 mm., long spindles, thorns scarce. The spicules of calyx 
0,; mm. The few spicules of the upper polyp-part 0,1 mm. in length. 
1883 Clavularia stormi KOorREN and DANIELSEN. 
From the illustrations accompanying the description of KOREN and DANIELSEN, 
it may be concluded that this species has broad, membranous stolons. They are, however, 
very small in reality, and the rather large polyps lie scattered, and not in lines, and the 
branches of the stolons are feeble and narrow. The spicules of the calyx are very 
characteristic and the spicules of upper poly-part are very few in number, 0,1 mm. 
long, spindles and rods. (Fig. 8 d.) 
General Distribution: 
Norway, Trondhjem Fiord, 300 met. (BrRocH 1912 a). 
Fam. Xeniidae VERRILL, 1866. 
Diagnosis: Alcyonaceae of soft, fleshy build. The polyps in their free parts are, 
for the most part, not retractile; they are connected in their lower part with coenenchym, 
which is provided with an endodermal canal system. The lower part of the colony 
consists of one or more simple or ramified, sterile trunks. Dimorphismus may exist. The 
spicules are small, flat, and lamellated, or are entirely absent.
