 bleg rosenrød med kastaniebrune Furer. De mindre Pigge 

 ligesom Pedicellarierne ere rosenrøde.

 Af de mangfoldige Exemplarer. der bleve fundne af 



Echinus norvegicus, var der kun faa, som helt igjennem sva- 

 rede til de af Diib. et Kor. beskrevne typiske Exemplarer. 

 Paa Undtagelser nær vare de meget større, havde alle de 

 Karakterer, som de nævnte Forfattere angive at tilhøre den 

 store Form fra Storæggen, en Havbro, som i aabne Havet 

 følger Norges Vestkyst i større eller mindre Afstand fra 

 denne. 



Echinus norvegicus er overordentlig udbredt, den gaar 

 i Syd ned til Bohuslehn (Sverige), hvor den dog forekom- 

 mer sjeldent og langs Norges hele Vestkyst til opimod 

 Beeren-Island. Den forekommer mig at være en nordisk 

 Art, der egentlig har sit Hjem i eller ved det aabne Hav ; 

 tirl imedens de Exemplarer, som tindes ved den sydlige Del 

 af Norge og i Bohuslehn ere meget smaa (Diib. et Kor. 

 Typer) tiltage de i Størrelse fra. Storæggen — 8 — 10 Mile 

 ud for Christianssund — og op til Vestfjorden, hvor den 

 synes at kulminere i Størrelse. Fra Vestfjorden bliver den 

 nordefter efterhaanden mindre, dog aldrig' saa liden som de 

 typiske Exemplarer. Det største Exemplar fandtes i den 

 aabne Vestfjord, og blev af Professor G. 0. Sårs erklæret 

 for at være hans Echinus rarispinus, og ved den første 



almost white sucking-disc. The primary spines are uni- 

 form chestnut-brown on the outermost half part; the inner- 

 raost half part is pale rose-red, with chestnut-brown grooves. 

 The round spines, as well as the pedicellaria are rose-red. 

 Distribution. Station 176. Only one specimen.

 Of the multitudinous specimens of Echinus norvegicus 



which were found, there were only a few that entirely cor- 

 responded to the typical specimens described by Diib. and 

 Kor. With only a few exc. j ptions they were verv large, 

 and possessed all the cbaracters the authors named report 

 as pertaining to the large form trom the great bank „Stor- 

 æggen", a bank which, in the open sea, lies off the west 

 coast of Norway at a greater or smaller distance from it. 

 Echinus norvegicus is extremely widely distributed ; it 

 passes southwards to Bohuslehn (in Sweden) where, 



however, it appears only rarely — and along the entire 

 coast of Western Norway as far north as to the vicinity 

 of Beeren Island. It appears to me to be a northern 

 species whose proper home is in, or near the open sea; 

 because, whilst the specimens found in the southern 

 portion of Norway and in Bohuslehn are very small (Diib. 

 and Kor. types) they increase in size from Storæggen 

 — 30—40 miles (Eng.) off Christianssund — and as far 

 north as Vestfiord, where the size appears to culminate. 

 From Vestfiord, northwards, it becomes gradually smaller 

 in size, yet never so small as the typical specimens. The 

 largest specimen was found in the open Vestfiord. and was
