Artskarakter. 
Femarmet Søstjerne med stærkt hvælvet Ryg og flad 
Bug. Den lille Radius forholder sig til den store som 1:4/3. 
Skivens Ryg besat med større og mindre Pigge, der tildels 
staa i Grupper. Paa Armenes Ryg staa Piggene i Tver-

Denne smukke, femarmede Søstjerne er en af de største, 
der blev funden paa Expeditionen. Dens Diameter udgjør 
3307™. 
Skivens Diameter er 527". Armenes Bredde ved 
Grunden 33”” og deres Høide 227", Den lille Radius for- 
holder sig til den store som 1:51/;. 
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 12” fra Armvinkelen, 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 Side- 
rækker ere mindre regelmæssige. 
Piggene ere ved deres Grund omgivne af en Krands 
korsformige Pedicellarier, Tab. IT, Fig. 1. Foruden disse Ræk- 
ker findes paa hver Side af Armene en Række meget lange, 
-steerke Pigge, der danne Ryggens Grændse. De staa tem- 
and nearly square; they carry 2 and 3 spines alternately

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.

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 1:44/;. 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 papille. 
Everywhere, on the rays and along the ventral furrow, 
three forms of pedicellariz visible. 
The colour orange-yellow; a deep red eye at the ex- 
tremity of the ray.

This beautiful five-rayed starfish is one of the largest 
which was discovered during the expedition. 
330”” in diameter. 
The diameter of the disk is 527”. The breadth of 
the rays is 33"”, and the height or thickness is 227”

The proportion of the disk- 
radius to the brachial radius is, as 1:51/3. 
and has 
only a few solitary short spines visible on the broad disk, 
otherwise, it is everywhere closely beset with rectiform 
The 
madreporite is circular, rather rotund, and is situated at a 
distance of 12”” from the interbrachial angle (Pl. IT, fig. 1). 
The rays are much rounded, and are furnished with 
The abactinal region is somewhat rotund, 
pedicellarize, between which tentacular tubes protrude. 
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 origin, environed by a wreath 
of cruciform pedicellariz (Pl. IT, fig. 1). Besides these 
series of spines, there occur on each side of the rays, 
very large, strong, spines, which form the dorsal margin.
