Ved den norske kyst er astarte crenata ikke funden 
søndenfor Lofoten. Den er en høiarktisk art, som er kjendt 
fra Grønland, Amerikas nord- og østkyst indtil Maine, 
Island, Jan Mayen, Spitsbergen, Barentshavet, Karahavet 
og videre østover indtil Taimurhalvøen (Vega station 26). 
Den bathymetriske udbredelse er 5—410 fy. Fossil er den 
funden i Skandinavien, Britiske ger, Island, nordlige Rus- 
land og Sibirien.

Astarte crenata is not found on the Norwegian coast 
south of Lofoten. It is a high-arctic species, found off 
Greenland, the north coast of N. America and east coast 
down to Maine, Iceland, Jan Mayen, Spitsbergen, in the 
Barents Sea, the Kara Sea, and eastwards as far as the 
Taimur Peninsula (Vega Station 26). Its bathymetrical 
distribution is from 5 to 410 fathoms. It is found as a 
fossil in Scandinayia, the British Isles, Iceland, the north 
of Russia, and Siberia.

Vi har her opført denne lille dybvandsform som en 
selvstændig art. Muligens bør den dog hellere betragtes 
som en dybvandsvarietet af foregaaende, fra hvilken den 
dog adskiller sig ved sin mere rhombiske form, finere strie- 
ring og smalere laasplade. 
Findested. Stationerne 18, 31, 33, 48, 124, 192, 
237, 251, 323, 359 og 363. Samtlige stationer med und- 
tagelse af de tre sidste tilhører den kolde area. Dybde 
223—649 fy. 
Astarte acuticostata, er tidligere kjendt fra Færø- 
kanalen, 229—450 fv. Jeffreys anfører den fra Novaja 
Semlja og Osterfjorden ved Bergen, men vi har ikke op- 
daget den der, uagtet vi har skabet en god del paa dette 
sted. Den bathymetriske udbredelse er 200 —649 fy.

We have here recorded this little deep-water form as 
a distinct species. It ought, however, possibly to be 
regarded rather as a deep sea variety of the preceding 
species, although it is distinguished from that species by 
its more rhombic form, finer striation, and narrower hinge. 
Locality. Stations 18, 31, 33, 48, 124, 192, 237, 
251, 323, 359, and 363. All these stations, with the ex- 
ception of the last three, belong to the cold area. Depth 
223—649 fathoms. 
Astarte acuticostata had previously been recorded from 
the Faroe channel (229—450 fathoms). Jeffreys states its 
occurrence in Novaja Semlja, and in Oster Fjord near 
Bergen; but although we have dredged a good deal in the 
latter locality, we have not detected it. Its bathymetrical 
distribution is from 200 to 649 fathoms.
