som paa den udvendige Flade har Korsformen med en
Fordybning 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
Tentakelpore. Tab. IX. Fig. 9, b.
De dorsale Randplader ere ovale, skivedannede med en
lidt konkav udvendig Flade, Tab. IX. Fig. 11 ,b, og støde
umiddelbart til de ventrale Randplader, Tab. IX, Fig. 10, a.
11, c. Disse ere lidt større men lidt mindre ovale end hine,
og hvile med sin indre (øvre) Flade 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
saaledes, at der dog imellem Pladerne er smaa Rum, Tab.
IX, Fig. 9, d,
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, c.
Solaster furcifer fandtes paa følgende Stationer:
Station 137, 2 Exemplarer. Ståt. 237, 2 Exempl.
Ståt. 343, et meget stort Exempl. Ståt. 359, et do.
Foruden paa de nævnte Stationer findes den langs
Norges Vestkyst fra Bergen til Nordkap, men meget sparsomt
overalt; ved de nordamerikanske Kyster; ved
Vestgrønlands 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
surface 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
assist in forming the above described rhomboidal meshes,
each of which includes a tentacular pore (Pl. IX, fig. 9, b).
The dorso-marginal plates are ovate, disk-formed, and
have a slightly concave exterior surface (Pl. IX. fig. 11, ft)
and they abut close upon the ventro-marginal plates (PI.
IX, figs. 10, a. 11, c). 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
irregular cruciform plates, whose projections rest upon each
other, but, still leaving small spaces between the plates (PI.
IX, fig. 9, d).
The odontophore has much similarity with that of
Solaster glacialis, but, both the dorsal and lateral
apophyses are somewhat larger, whilst, also, a groove occurs
in the middle of the superior margin (Pl. IX, fig. 9, c).
Solaster Jurcifer was found at the following stations:
Station No. 137, 2 specimens.
— „ 237, 2 —
— ,, 343, 1 very large specimen.
— „ 359] 1 * —
Besides the stations named, it is found along the
Norwegian coast from Bergen to the North Cape, but,
everywhere, sparingly. It is also found1 on the North
American Coast; the Greenland Coast; and at Nova Zembla.
