næsten firkantede, og bære afvexlende 2 og 3 Pigge, Fig.
3, a. 11, c.
Farven orangegul med et intens rødt Øie paa Enden
af hver Arm. Fødderne noget mørkere orangegule.
Spiri-tusexemplarer bleggule.
Findested.
Magdalena Bay, Spitsbergen. Ståt. 366.
Artskarakter.
Femarmet Søstjerne med stærkt hvælvet Ryg og flad
Bug. Den lille Radius forholder sig til den store som l:4l/s.
Skivens Ryg besat med større og mindre Pigge, der tildels
staa i Grupper. Paa Armenes Ryg staa Piggene i
Tver-rækker og paa Siderne i Længderækker. Imellem Piggene
Tentakelporer i den nøgne Hud. Analaabningen central.
Madreporpladen liden, lidt aflang, nedsænket i Huden strax
ovenfor Armvinkelen. Ambulaeralfuren forsynet med 3
Rækker Papiller. Overalt paa Armene og langs Bugfuren
Pedicellarier i 3 Former.
Farven orangegul; et intens rødt Øie paa Armenes
Spids.

Denne smukke, femarmede Søstjerne er en af de største,
der blev funden paa Expeditionen. Dens Diameter’ udgjør
330"".
Skivens Diameter er 52"". Armenes Bredde ved
Grunden 33"m og deres Høide 22mm. Den lille Radius
forholder sig til den store som l:51/3.
Rygsiden noget hvælvet. Paa den brede Skive sees
meget faa, enkeltstaaende, korte Pigge, forøvrigt er den
overalt tæt besat med ligedannede Pedicellarier, hvorimellem
Tentakelrørene strække sig frem. Madreporpladen rund,
temmelig hvælvet, og fjernet 12mm fra Arm vinkelen, Fig. 1.
Armene" meget hvælvede, besatte med 5 Længderækker
Pigge, hvoraf den, der følger Armens Midtlinie, er meget
regelmæssig og har de største Pigge, imedens de to
Siderækker ere mindre regelmæssige.
Piggene ere ved deres Grund omgivne af en Krands
korsformige Pedicellarier, Tab. II, Fig. 1. Foruden disse
Rækker findes paa hver Side af Armene en Række meget lange,
stærke Pigge, der danne Ryggens Gi’ændse. De staa tem-
and nearly square; they carry 2 and 3 spines alternately
(figs. 3, a. 11, c).
The colour is orange-yellow, with a deep red eye at
the extremity of each ray. The suckers are of a somewhat
darker orange-yellow colour. When preserved in spirit the
colour is pale yellow.
Habitat.
Madeleine Bay, Spitzbergen, Station 366.
Specific Character.
A five-rayed starfish with sharply rounded abactinal
surface and flat actinal surface. The disk-radius bears to
the brachial radius, the proportion of as 1:473. The abactinal
disk beset with longer or shorter spines, arranged partly,
in groups. On the dorsal surface of the rays, transverse
series of spines, and on the lateral surfaces, longitudinal
series of spines. The integument is bare between the spines,
and the seat of tentacular pores. A median anal opening.
The madreporite small, somewhat ovate, and embedded in
the integument, immediately above the inter brachial angle.
The ambulacral furrow furnished with 3 series of papillæ.
Everywhere, on the rays and along- the ventral furrow,
three forms of pedicellariæ visible.
The colour orange-yellow; a deep red eye at the
extremity of the ray.

This beautiful five-rayed starfish is one of the largest
which was discovered during the expedition. It measures
330mm jn diameter.
The diameter of the disk is 52mm. The breadth of
the rays is 33"’", and the height or thickness is 22m",
both, measured at the origin. The proportion of the
disk-radius to the brachial radius is, as l:51/3.
The abactinal region is somewhat rotund, and has
only a few solitary short spines visible on the broad disk,
otherwise, it is everywhere closely beset with rectiform
pedicellariæ, between which tentacular tubes protrude. The
madreporite is circular, rather rotund, and is situated at a
distance of 12mm from the interbrachial angle (Pl. II, fig. 1).
The rays are much rounded, and are furnished with
5 longitudinal series of spines, of which, the series in the
medial line of the ray is very regular, and has the longest
spines, whilst, the two lateral series are less regular.
The spines are, at their oi’igin, environed by a wreath
of cruciform pedicellariæ (Pl. II, fig. 1). Besides these
series of spines, there occur on each side of the rays,
very large, strong, spines, which form the dorsal margin^
