hvilken ganske mangler hos Stichaster arcticus. 
Hudskelettet er mere aabent, har større Masker, saa 
at flere Tentakelrør kunne passere dem hos Stichaster ro- 
seus, imedens det hos Stich. arcticus er tættere, Maskerne 
mindre, saa at kun et Tentakelrør kan træde igjennem.

Der blev fundet af denne Søstjerne nogle Exemplarer 
i Sognefjorden (Husøen) paa 40—50 Fayne samt paa 25de 
Station et Par Exemplarer. En Arm af et ungt Exem- 
plar er afbildet for at vise Forskjellen imellem dens Hud- 
skelet og det hos Stichaster arcticus. NSaavidt os bekjendt 
er den hidtil kun fundet ved. den engelske og norske Kyst, 
og ved den sidste ikke nordligere end 25de Station.

the fact is, that situated between these and the former, 
there is a series of slender, oblong, caleareous plates, car- 
rying a spine, so, that, im Stichaster roseus, we find a se- 
ries of spines between the ambulacral papillæ and the vent- 
ral spines already spoken of, which are placed 3 and 3 
together, and this feature is entirely awanting in Stichas- 
ter arcticus. : 
The dermal skeleton in Stichaster roseus is more open, 
and has such large meshes, that several tentacular tubes 
can be included in them, whilst, in Stichaster arcticus, the 
dermal skeleton is closer, and the meshes smaller, so, that 
they cannot include more than one tentacular tube.

Several specimens of this Starfish were found, at a 
depth of 40—50 fathoms, at Husøen (Sognefjord), and also, 
a couple’ of specimens, at station No. 25. A ray of a 
young specimen is illustrated, to show the difference, be- 
tween its dermal skeleton, and that of Stichaster arcticus. 
As far as we are aware, it has, hitherto, only been found 
on the British and Norwegian coasts, and on the last 
named, not further North than station No. 25.
