Nogle døde skaller og skalfragmenter af denne art 
fandtes paa stat. 255 (Vestfjorden), 341 fy. 
Lima excavata er almindelig paa de nederste afsatser 
mod fjorddybene langs hele den norske kyst. Den er des- 
uden kjendt fra dybet mellem Hebriderne og Færøerne, 
Portugal, Azorerne og Senegambien.

Fra Japan omtaler Sowerby en kjæmpemæssig lima, 
lima goliath*), som senere er gjenfunden af Challenger expedi- 
tionen syd for Japan, 775 fv. og Vest of Sydpatagonien, 
245 fv.*). Fra den nordiske lima excavata skal den ad- 
skille sig ved sit mere buede skal, ved en noget afvigende 
striering og ved en større og dybere cardinal area. Hos 
lima excavata er imidlertid, selv hos exemplarer fra samme 
lokalitet, skallets form og dets striering i høi grad vari- 
erende. Fra Nordfjord har vi saaledes en række exem- 
plarer, som i saa henseende ikke kan adskilles fra Sowerbys 
art. Af større betydning synes den cardinale area at være, 
om end ogsaa denne er meget varierende. Det er derfor 
et spørgsmaal, om ikke ma goliath, Sow. rettest bør be- 
tragtes som en kjæmpemeæssig varietet af Uma excavata, 
Fabr.

Some empty valves and fragments of shell of this 
species were found at Station 255 (West Fjord), at a depth 
of 341 fathoms. 
Lima excavata is common on the deepest coast-led- 
ges of the fjords all along the Norwegian coast. It is also 
known in the deep water between the Hebrides and the 
Faroe Isles, in Portugal, the Azores and Senegambia. Its 
bathymetrical distribution is from 150 to 982 fathoms. It 
is found as a fossil in Norway and Calabria. 
Sowerby mentions a gigantic Lima from Japan, Lima 
goliath*), which was subsequently found again by the Chal- 
lenger Expedition south of Japan in 775 fathoms, and 
west of South Patagonia in 245 fathoms?). It is distin- 
guished from the Scandinavian Lima excavata by its more 
convex shell, a somewhat different striation, and a larger 
and deeper cardinal area. In Lima excavata, however, even 
in specimens from the same locality, the form and striation 
of the shell vary very considerably. We have, for instance, 
a number of specimens from the Nord Fjord, which in 
these respects cannot be distinguished from Sowerby’s spe- 
cies. The cardinal area appears to have more significance, 
although it too varies greatly. It is therefore a question 
whether Lima goliath, Sow. should not properly be consi- 
dered as a gigantic variety of Lima excavata, Fabr.

Lima loscombii toges af Nordhaysexpeditionen ved 
Husø, 40—60 fy. og ved stat. 192, 649 fy. 
Den er almindelig ved den norske syd- og vestkyst 
op til Lofoten (Skraaven). Arten er forøvrigt kjendt fra 
Middelhavet og det nordøstlige af Atlanterhavet mellem 
Lofoten og Færøerne i nord og Azorerne og kysten af 
Senegambien i syd. Desuden har Challengerexpeditionen 
den fra Tristan da Cunha og Nightingale Island i Syd- 
havet. Den batbymetriske udbredelse er 20—1440 fv. 
Fossil er den funden i Norge, Belgien, Italien og Rhodes.

Lima loscombii was taken by the North Atlantic 
Expedition at Huso in depths of from 40 to 60 fathoms, 
and at Station 192 in 649 fathoms.

way, as far north as Lofoten (Skraaven). The species
