Lima cxcarafa er almindelig paa de nederste afsatser 

 mod fjorddybene langs hele den norske kyst. Den er des- 

 uden kjeudt fra dybet mellem Hebriderne og Færoerne, 

 Portugal. Azorerne og Senegambien. Dens bathymetriske 

 udbredelse er 150 — 982 fv. Fossil er den funden i Norge 

 og Kalal)rien. 



Fra Japan omtaler Sowerby en kjænipeina;'ssig lima. 

 lima i/oJiafJi^). som senere er gjenfunden af Cliallenger expedi- 

 tionen sytl 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 storre og dybere cardinal area. Hos 

 lima excavata er imidlertid, selv hos exemplarer fra samme 

 lokalitet, skallets form og dets striering i hoi grad vari- 

 erende. Fra Nordfjorcl har vi saaledes en i-ække exem- 

 plarei", som i saa henseende ikke kan adskilles fra Sowerbys 

 art. Af storre betydning synes den cardiuale area at være, 

 om end ogsaa denne er meget varierende. Det er derfor 

 et sporgsmaal. om ikke lima goliafji, Soiv. rettest bør be- 

 tragtes som en kjæmi)emæssig varietet af lima excavata,

Sorae empty valves and fragments of shell of this 

 spedes were found at Station 255 (West Fjord), at a deptli 

 of 341 fatlioms. 



Lima e.iravata is commou 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 

 Farne Isles, in Portugal, the Azores and Senegambia. Its 

 bathymetrical distribution is' from 150 to 982 fathoms. It 

 is found as a fossil in Xorway and Calabria. 



Sowerby meutions a gigantic Lima from Japan, Lima 

 goliath '), which was subsequently found again by the Clial- 

 lenger Expedition south of Japan in 775 fathoms, antl 

 west of South Patagonia in 245 fathoms-). It is distin- 

 guished from the Scandinavian Lima excavata h\ 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 siiell vary very considerably. We have. for instnnce. 

 a number of specimens from the Nord Fjord, which in 

 these respects cannot be distiuguished 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 ijoliath. Sow. should not properly be consi- 

 dered as a siigantic varietv of Lima excarata. Fabr.

Lima loscomhii toges af Xordhavsexi)editioneu ved 

 Huso. 40— 6U iv. og ved stat. 192, 649 fv. 



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 F;erøerne i nord og Azorerne og kysten af 

 Senegambien i syd. Desuden har Challengerexpeditionen 

 den fra Tristan da Cuuha og Nightingale Island i Syd- 

 havet. Den bathymetriske udbredelse er 20 — 1440 fv. 

 Fossil er den funden i Norge, Belglen, Italien og Rhodes. 



Lima hiscomhii was tåken h\ the North Atlantic 

 Expedition at Huso in cleptlis of from 4(1 to tid fathoms, 

 and at Statiou 192 in 649 fatlioms. 



It is common ofl' the south and west coasts of Nor- 

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

 is also known in the Mediterranean and the north- 

 eastern regions of the Atlantic between Lofoten and the 

 Faroe Isles in the north, and the coast of Senegambia in 

 the south. It was also found liy the Challenger Expedi- 

 tion off Tristan da Cunha and Xightiugale Island in the 

 South Pacific. Its l)athymetrical distribution is from 20 

 to 144IJ tathoms. It is found as a fossil in Norway, Bel- 

 gium. Italv and Rhodes.
