Den er en cireumpolar art, som forekommer ved 
Grønland, Amerikas nord- og østkyst, Jan Mayen, Island, 
Spitsbergen, Murmankysten, Hvidehavet, Novaja Semlja, 
Karahavet, Sibirien, Okotske hav. Den bathymetriske ud- 
bredelse er 2—120 fy. Til ovennærnte dybdeangivelse fra 
station 353, 1333 fv., kan der vanskelig tages hensyn, da 
den staar 1 strid med alle tidligere observationer, desuden 
erholdtes arten paa denne lokalitet kun i et meget beska- 
diget skal. Fossil er den kjeudt fra Sverige og det nord- 
lige Rusland.

It is a circumpolar species, occurring off Greenland, 
the north and east cousts of North America, Jan Mayen, 
Iceland, Spitsbergen, the Murman Coast, in the White 
Sea, Novaja Semlja, the Kara Sea, Siberia, and the Sea 
of Okhotsk. Its bathymetrical distribution is from 2 to 
120 fathoms. It is hardly possible to pay any regard 
to the aboye statement of the depth at Station 3853 — 
1333 fathoms — as it is at variance with all previous ob- 
servations, and moreover, the species was represented in 
this locality by only one large fragment. It as fossil in 
Sweden and the north of Russia.

Findested. Stationerne 124, 
312 og 323. Dybde 191—778 fy. Exemplarerne fra sta- 
tion 312 udmerkede sig ved sin usædvanlige størrelse. Sars 
angiver denne arts længde til 5 mm., disse var derimod 
indtil 9 mm. lang. ; 
Lyonsiella abyssicola er tidligere kjendt fra Baffins- 
bugten, Grønlands vestkyst, New England, Spitsbergen, 
Barentshavet, Hvidehavet, Norges nord- og vestkyst, Irlands 
vestkyst, Kanalen og Portugal. Den bathymetriske udbre- 
delse er 90—1095 fv.

Locality. Stations 124, 192, 248, 251, 290, 312, 
and 323. Depth 191—778 fathoms. The specimens from 
Station 312 were remarkable for their unusual size. Sars 
gives the length of this species as 5 mm., whereas these 
were as much as 9 mm. in length. 
Lyonsiella abyssicola is known in Baffin's Bay, off the 
west coast of Greenland, New England, Spitsbergen, the 
Barents Sea, the White Sea, off the north and west 
coasts of Norway, the west coast of Ireland, in the Eng- 
lish Channel and Portugal. Its bathymetrical distribution 
is from 90 to 1095 fathoms.

There are two large, well-preserved right valves of 
Lyonsiella jeffreysi, and some fragments from Station 205 
(1100 fathoms), and the upper part of a right valve from 
Station 312 (656 fathoms). The species has not yet been 
observed elsewhere than off Spitsbergen.
