Ved deu norske kyst er astarte crenata ikke funden 

 sondenfor Lofoten. Den er en hoiarktisk 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 hathymetriske udbredelse er 5 — 410 fv. Fossil er den 

 funden i Skandinavien, Britiske oer. Island, nordlige Rus- 

 land o<i' Sihirien.

Astarte crenata is not found on the Norwegian coast 

 south of Lofoten. It is a high-arctic species, found ofT 

 Greenland, the north coast of N. America and east coast 

 down to ]\raine, 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 Scandinavia, the British Isles, Iceland. the iiortli 

 of Russia. and Siberia.

^'i liar her opfort denne lille dybvandsform som en 

 selvstændig art. Muligens bør den dog hellere betragtes 

 som en dybvandsvarietet af forega ående, fra hvilken den 

 dog adskiller sig ved sin mere rhombiske form, finere strie- 

 i'ing og smalere hiasplade. 



Findested. Stationerne 18, 31, 33, 48, 124, 192. 

 237, 251, 323, 359 og 363. Samtlige stationer med und- 

 tagelse af de tre sidste tilhorcr den kokle area. Dybde

Astarte acuticostata. er tidligere kjendt fra Fa-ro- 

 kanalen, 229 — 450 fv. .Teffreys anfører den fra Novaja 

 Seralja og Ostertjorden ved Bergen, men vi har ikke op- 

 <laget den der, iiagtet vi har skabet en god del paa dette 

 .sted. Den bathymetriske udbredelse er 200 — 649 fv. 



We have here recorded this little deep-water form as 

 a distinct species. It ouglit, however. jiossibly to be 

 regarded rather as a deep sea variety of the jireceding 

 species, although it is distinguished from that species by 

 its more rhombie form, finer striation, and narrower hiuge. 



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. Dcptii 

 223—649 fathoms. 



Astarte acuticostata bad jjreviously been recoi-ded fi'oni 

 the Faroe ciiannel (229 — 450 fathoms). Jeffreys states its 

 occui-rence in Novaja Semlja, and in Oster Fjoi'd near 

 Bergen; bnt 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.
