Af denne art foreligger der kun fra Norskøerne, 10 
—20 fy., et yngre individ og et høire skal, der var 21 
mm. langt og 24 mm. bredt. 
Diplodonta torelli er kun kjendt fra Spitsbergen. 
Valorousexpeditionen hjembragte fragmenter fra station 12, 
56° 11" N. Br., 37° 41" V. Lg., 1450 fy., antagelig hører dog 
ikke arten hjemme paa dette dyb, men er uddrevet af isen.

Å young specimen, and a right valve measuring 21 mm. 
in length and 24 mm. in breadth, from the Norwegian 
Islands (Spitsbergen) (10-—20 fathoms), is all that was 
found of this species. 
Diplodonta torelli is only known from Spitsbergen. 
The Valorous Expedition brought back fragments from Sta- 
tion 12 (560 11’ N. Lat., 37° 41’ W. Long., 1450 fathoms) ; 
but the species is probably not a native of this depth, 
but has been carried out by the ice.

Axinus flexuosus er en af de hyppigst forekommende 
mollusker, idet den foreligger fra ikke mindre end 29 loka-

Advendt Bay og Magdalena Bay, 20—30 fy. Dybde 2(— 
672 fy. 
Exemplarerne tilhører dels hovedformen flexuosus, dels 
varieteterne særs og gouldii. Den sidste synes særlig at 
være en arktisk form, idet samtlige exemplarer fra Jan 
Mayen og Spitsbergensomraadet tilhører denne. Ved Grøn- 
lands østkyst er det ligeledes blot denne, som optræder 
(Posselt). 
Flere malacologer betragter saavel sarsii som gouldii 
som selvstændige arter, men maa vi med Jeffreys anse 
dem som varieteter, da de gaar umærkelig over i hinanden. 
Axinus fleruosus er en circumpolar art, som inden 
Atlanterhavsomraadet gaar mod syd til Adriaterhavet, Mid- 
delhavet, Nordafrikas vestkyst, Azorerne, Kanariske ger, 
St. Thomas og Den mexikanske golf. Inden det pacfik- 
arktiske omraade er den kjendt fra Sibiriens ishavskyster, 
Beringshavet, Korea og Nordamerikas vestkyst indtil Kali- 
fornien. Den er almindelig langs hele den norske kyst, 
formen gouldii er dog sjelden søndenfor Bodø. Den bathy- 
metriske udbredelse er 5—1095 fy. Fossil er den kjendt 
fra Spitsbergen, Grønland, Nordamerika, Skandinavien, 
nordlige Ruslaud, Britiske øer. Belgien, Frankrig, Italien 
og Madeira.

Axinus flexuosus is one of the most frequently-occur- 
ring molluses, having been found in no less than 29 loca- 
lities, namely, Stations 1, 2, 9, 18, 31, 33, 79, 87, 137, 
192, 223, 224, 251, 255, 261, 262, 267, 273, 290, 323, 
326, 338, and 357. It was moreover found in the Sogne 
Fjord (100 fathoms), Husø, Advent Bay, and Magdalena 
Bay (20—30 fathoms). Depth 20—672 fathoms. 
Some of the specimens belong to the principal form 
The 
last-named appears especially to be an arctic form, as all 
the specimens from the Jan Mayen and Spitsbergen region 
belong to it, and it is also the only form appearing on 
the east coast of Greenland (Posselt). 
Several malacologists regard both sarsti and gouldii 
as distinct species; but we agree with Jeffreys in considering 
them as varieties, as the transition from the one to the other 
is imperceptible. 
Azinus flexuosus is a circumpolar species, which, in 
the Atlantic region, extends southwards to the Adriatic, 
the Mediterranean, the north-west coast of Africa, the 
Azores, the Canary Islands, St. Thomas, and the Gulf of 
Mexico. In the Pacific-Arctic region, it is known off the- 
Siberian shores of the Arctic Ocean, in the Bering Sea, 
the Corea, and off the west coast of North America down 
to Califormia. It is common all along the Norwegian coast, 
the form gouldii, however, being rare south of Bodø. Its 
bathymetrical distribution is from 5 to 1095 fathoms. It 
is found as a fossil in Spitsbergen, Greenland, North 
America, Scandinavia, the north of Russia, the British 
Isles, Belgium, France, Italy, and Madeira.
