som paa den udvendige Flade har Korsformen med en For- 
dybning paa Midten, der er Artikulationsfladen for den 
Paxille, som hver Plade bærer, Tab. IX, Fig. 11, a; den 
indvendige Flade af disse Kalkplader har Udseendet af et 
X med temmelig lange Arme, der hjælpe til at danne de 
ovenfor omtalte, rudeformige Masker, som hver har en Ten- 
takelpore. Tab. IX. Fig. 9. 0. : 
De dorsale Randplader ere ovale, skivedannede med en 
lidt konkav udvendig Flade, Tab. IX, Fig. 11,0, og støde 
umiddelbart. til de ventrale Randplader, Tab. IX, Fig. 10, a. 
I1,c. Disse ere lidt større men lidt mindre ovale end hine, 
og hvile med sin indre (øvre) Fiade paa Adambulacralpla- 
derne paa Armen, Tab. IX, Fig. 10, b, imedens de i In- 
terbrachialrummene støde til Bugpladerne; forresten have 
de samme Form som de dorsale Randplader. 
Bugfladens Hudskelet bestaar af lidt uregelmæssigt 
korsformede Plader, hvis Udløbere hvile paa hverandre saa- 
ledes, at der dog imellem Pladerne er smaa Rum, Tab.

Odontophoren har megen Lighed med den hos Sol- 
aster glacialis, dog er baade Rygapophysen og Sideapophy- 
serne noget større, ligesom der paa Midten af øverste Rand 
findes et Indsnit, Tab. IX, Fig. 9, ©. 
Solaster furcifer fandtes paa følgende Stationer: 
Station 137, 2 Exemplarer. Stat. 237, 2 Exempl. 
Stat. 343, et meget stort Exempl. Stat. 359, et do. 
Foruden paa de nævnte Stationer findes den langs Nor- 
ges Vestkyst fra Bergen til Nordkap, men meget sparsomt 
overalt; ved de nordamerikanske Kyster; ved Vestgrøn- 
lands Kyster; ved Novaja Semlja.

with small rhomboidal meshes, formed by calcareous plates, 
which, on their exterior surface, have the form of a cross, 
with a cavity in the middle forming the articulatory sur- 
face for the paxilla which each plate carries (Pl. IX, fig. 
11, a). The interior surface of these calcareous plates has 
the appearance of an X with rather long arms, which as- 
sist in forming the above described rhomboidal meshes, 
each of which includes a tentacular pore (Pl. TX, fig. 9,0). 
The dorso-marginal plates are ovate, disk-formed, and 
have a slightly concave exterior surface (Pl. IX, fig. 11,0) 
and they abut close upon the ventro-marginal plates (PI. 
IX, figs. 10, a. 11, 6). The ventro-marginal plates are a 
little larger. and not quite so ovate as the former, and they 
rest with their inner superior surface, on the adambulacral 
plates (Pl. IX, fig. 10, b), of the ray, whilst, those of the 
interbrachial space abut upon the ventral plates; in other 
respects, they are like the dorso-marginal plates in form. 
The actinal dermal skeleton consists, of rather irreg- 
ular cruciform plates, whose projections rest upon each ot- 
her, but, still leaving small spaces between the plates (PI. 
ID, 18; BG), 
The odontophore has much similarity with that of 
Solaster glacialis, but, both the dorsal and lateral apo- 
physes are somewhat larger, whilst, also, a groove occurs 
in the middle of the superior margin (Pl. IX, fig. 9, c). 
Solaster furcifer was found at the following stations:

very large specimen. 
Besides the stations named, it is found along the 
Norwegian coast from Bergen to the North Cape, but, ev- 
erywhere, sparingly. It is also found on the North Amer- 
ican Coast; the Greenland Coast; and at Nova Zembla.
