Denne art, .som al' Jeffreys er henfort til lioflii/ris 

 ritrea rar. minor (Proc. Zool. Soc. 1878, p. 4U4) er ikke 

 alene opretholdt af David.son, men ogsaa af Fischer it Oehlert 

 i deres monografi over brachio])oder fra „Travailleur" og 

 ..Talisman- (p. 56). 



Af Nordhavsexpeditionen fandtes Jiotlii/ris ardica kun 

 paa en loktilitct ved Jan Mayen, stat. 237, 263 fv. Den 

 er forovrigt kun kjendt fra Grønlands østkyst og Islands 

 nordvestkvst. 120—160 fv. 



This si)eries, which is referred liy Jeffreys to Liallii/ris 

 vitrea rar. minor (Proc. Zool. Soc. 1878. p. 404), is not 

 only maintained liy Davidson, but also liy Fisciier & Oehlert 

 in their nionogr;iph cm the Brachiopoda from the 'Travailleur" 

 and the 'Talisman' (p. 56). 



LiotJti/ris ardica was foiind by the Norwegian Nortli 

 Atlantic E.K|)edition in only one locality off Jan Mayen. 

 Station 2o7 (263 fathoms). In addition to this, it hns 

 only been found off the east coast of Greenland and the 

 north-west coast of Iceland (120 — 160 fathoms).

Waklheimia .septigera forekommer sparsomt paa de 

 storre dyb. ved vor nord- og vestkyst. Ved Østfinmarken 

 er den dog endnu ikke funden. Dens udbredelse synes 

 at være mere sydlig end WaldJicimia craniu)iis\ den 

 mangler nemlig fra de hoiarktiske farvande. Den er 

 kjendt fra Vestfinmarken og Fa-roerne til Gap Bojador 

 (25" 38' X. Br.), Canariske oer og Azorei^ne. Den kan 

 derfor ikke som af Sårs lietegnes som en arktisk art. 

 Den bathymetriske udbredelse er 75 — 725 fv. Fossil er 

 den funden i de postglaciale afleiringer ved Christiansund 

 samt i de tertiære las i Italien.

Waldheimia septigera is of sparse occurrence in 

 great depths off the north and west coasts of Norway. 

 It has not yet been found in east Finmark. Its 

 distribution appears to he more southern than tiiat of 11'. 

 craiiiinn. for it is absent from the high arctic waters. It is 

 found from west Finmark and the Faroe Isles to Cape 

 Bojador (25" 38' W. Long\ the Canary Isles nnd the 

 Azores. It cannot tiierefore be designated, as Sårs has 

 designated it, an arctic si)ecies. Its bathymetrical distribu- 

 tion is from 75 to 725 fathoms. It is found as a fossil 

 in the post-glacial deposits at Christiansund. aud in the 

 tertiarv strata in Italv.
