Ogsaa paa denne Søstjerne have vi undersøgt Skelet- 
delene, afbildet en Del deraf og kommer længere hen at 
omtale dem. 
Den er meget almindelig langs hele Norges Kyster. 
Paa Expeditionen blev den funden paa følgende Stationer: 
267, 1 Exemplar (ikke meget stort, men dog udvoxet) med 
8 Arme. 280, et lidet Exemplar. 315, 1 do. 3863, 2 me- 
get store Exemplarer.  Desforuden er den udbredt ved 
den murmanske Kyst. de færøiske, islandske. grønlandske, 
britiske og nordamerikanske Kyster. 
Slægten Solaster, først opstillet af Forbes, har til for- 
skjellige Tider været underkastet en særskilt Bedømmelse, 
idet nogle Forskere, saasom Liitken, Duncan & Sladen og 
A. Agassiz have udtalt sig for, at dens to Arter, S. endeca 
og papposus, burde deles i to Slægter, — og Agassiz har 
da for Sol. papposus's Vedkommende optaget Miiller & Tros- 
chels Benævnelse Crossaster, — imedens Andre, f. Ex. Vi- 
guier og Perrier ikke vil vide af nogen Deling og have 
derfor bibeholdt Forbes's oprindelige Slægtsnavn. 
Professor Verrill har opstillet en ny Slægt, Lophaster, 
for en tredie Art, nemlig Solaster furcifer, hvilken enkelte 
Naturforskere ere tilbøielige til at godkjende. Der er saa- 
ledes for ikke mindre end 3 Arter af den forresten paa 
Arter fattige Slægt, Solaster, dannet 3 Slægter: Lophaster, 
Crossaster og Solaster, og det er disse. vi nu skulle under- 
kaste en kritisk Bedømmelse.

posus som Typen for en ny Slægt og benævnt den Cyoss- 
aster, der er Miller & Troschel's første Slægtsnavn for

We have also examined the skeleton parts of this 
starfish, and have illustrated a portion of these; and will 
subsequently proceed to speak of them. 
This Starfish is a very common one along the whole 
of thr Norwegian coast. During the expedition it was 
found at the following stations: 
Station No. 267. One specimen (not a very large specimen. 
but still, full grown) having 8 rays. 
— 280. One small specimen. 
— » 315. One small specimen. 
— » 9363. Two very large specimens. 
Its distribution, is, otherwise. The Murman Coast. The 
Faroe Islands. Iceland. The coast of Greenland and the 
British and North American coasts. 
The genus Solaster. originated by Forbes, has been at 
various times submitted to special criticisms, and some 
Naturalists, such as Liitken, Duncan and Sladen, and A. 
Agassiz, have expressed the opinion, that its two species, 
Solaster endeca and Solaster papposus, ought to be classed 
as two genera. Agassiz also, has in reference to Solaster 
papposus adopted Miiller and Troschel’s designation Cross- 
aster, whilst some others, as for instance, Viguier, and 
Perrier, will not admit of any division, and have therefore 
retained Forbes’ original generic designation. 
Professor Verrill has presented a new genus, Loph- 
aster, instead of a third species viz. Solaster furcifer, and this, 
some naturalists are inclined to accept. There is thus; 
for no fewer than three species of the genus Solaster, so 
poor otherwise in species; adopted three genera, viz. Loph- 
aster, Crossaster and Solaster. We shall now submit these 
to a critical examination.

as the type of a new genus, which he named Crossaster ;
