Natica grønlandica har sin sydgrænse inden Atlanter- 
havsomraadet ved New England, Britiske øer, Ostende og 
Kattegat; inden Pacifikomraadet gaar den mod syd til det 
nordlige Japan. Desuden er den funden af Challenger-ex- 
peditionen ved Heard Island, SSO af Kerguelen. Den 
bathymetriske udbredelse er 2---1290 fy. Fossil er den 
funden i Skandinavien, Britiske ger, Island, Spitsbergen, 
nordlige Rusland, Sibirien og Nordamerika.

and 357, Hammerfest (20 fathoms), Advent Bay and Mag- 
dalena Bay (20—30 fathoms). Depth 20—658 fathoms. 
The southern limit of Natica grænlandica in the At- 
lantic is at New England, the British Isles, Ostend, and 
the Kattegat, and in the Pacific at the north of Japan. It 
was also found by the ‘Challenger’ at Heard Island, SSE 
of Kerguelen Land. Its bathymetrical distribution is from 
2 to 1290 fathoms. It is a fossil in Scandinavia, the Bri- 
tish Isles, Iceland, Spitsbergen, northern Russia, Siberia, 
and N. America.

Ved skallets forholdsvis større længde og ved den 
høie, mere langstrakte mundaabning, afviger natica pallida 
saa meget fra gronlandica, at vi foretrækker at opretholde den 
som egen art. Da tegningen til ,,Blossom*-exemplaret er 
udført af Sowerby, og da han ligeledes deltog sammen med 
Gray i bearbeidelsen af de ved kaptein Beechey's reise 
indsamlede mollusker, er der al grund til at antage, at det 
afbildede exemplar er en typisk natica pallida, Broderip & 
Sowerby. —

Locality. Stations 223, 224, 225, 267 and 336, and 
Magdalena Bay (30 fathoms). Depth 50—195 fathoms. 
Natica pallida differs so greatly from grænlandica in 
its comparatively greater length, and its more elongated 
aperture, that we prefer to retain it as a 
species. As the drawing of the ‘Blossom’ specimen is by 
Sowerby, and as that writer also collaborated with Gray 
in the classification of the Mollusca collected during Cap- 
tain Beechey’s voyage, there is every reason to suppose 
that the specimen depicted is a typical Natica pallida, 
Broderip & Sowerby.

Natica 
Lunatia 
Denne art foreligger kun i nogle faa exemplarer fra 
Norskøerne, 10—20 fy. 
Hos os er natica nana blot tagen ved Vardø og Vadsø. 
Forøvrigt er den kjendt fra Murmankysten, Hvidehavet, 
Spitsbergen, Grønland, New England, St. Lawrencebugten 
og Aleuterne. Porcupineexpeditionen har faaet et par døde 
skaller ved Skotlands vestkyst, Caudan har den fra Biskayer- 
bugten og Talisman fra Nordafrikas vestkyst. 
metriske udbredelse er 10—910 fy.

There are only a few specimens of this species, from 
the Norwegian Islands (10—20 fathoms). 
In Norway, Natica nana has only been found at 
Vardø and Vadsø. It further occurs off the Murman Coast, 
in the White Sea, off Spitsbergen, Greenland, New England, 
the Guif of St. Lawrence, and the Aleutian Isles. The 
‘Porcupine’ Expedition found a few empty valves on the 
west coast of Scotland; the ‘Caudan’ found it in the Bay 
of Biscay, and the *Talisman* off the north-west coast of 
Africa. Its bathymetrical distribution is from 10 to 910 
fathoms.
