74. Diastylis Rathkii, (KrSyer). 



Exemplarer at' denne ved vore Kyster niegcl alminde- 

 lige, paa sine Steiler i store Masser forekommende Art 

 toges under Expeditionen i Saltenfjord, Kjosen og Pors- 

 angerfjord, fremdeles i Adventbay paa Spitzbergen samt 

 paa Stat. 18. 192 og 357, de 2 første beliggende i Havet 

 udenfor vor Kyst. den sidste V at' Spitsbergen; Dybden 

 indtil 649 Favne. 



Skjondt Arten gaar sydlig til Pommerens Kyst. er 

 den dog utvivlsomt at betragte sum en oprindelig arktisk 

 Form, da den er udbredt til Grønland, Nordamerikas Øst- 

 kyst, Sibiriens Ishav og det kariske Hav. To af de Sta- 

 tioner, hvor den under vor Expedition blev observeret, til- 

 hører desuden den kolde Area. 



75. Diastylis cornuta. Boeck. 



Denne ved vore Kyster ligeledes meget almindelige 

 Art observeredés under Expeditionen ved Husø paa 80 — 

 100 Favnes Dybde. Den er aaberibart en mere sydlig Form 

 og udbredt til de britiske Øer (D. bicornis Sp. Hate) og 

 Vestkysten af Frankrige (Fischer). Norman autorer den 

 ogsaa fra Porcupine-Expeditionen som forekommende paa 

 stort Dyb i Atlanterhavet. Den af samme Forfatter under 

 Benevnelsen I) strigata beskrevne Form anser jeg for den 

 fuldt udviklede Han af nærværende Art. 



76. Diastylis echinata. Sp. Bate. 



Fortiden ved Huso blev denne Art under Expeditio- 

 nen observeret paa 2 i Havet udenfor vor Vestkyst belig- 

 gende Stationer (Stat. 31 og 124 1. begge tilhørende den 

 kolde Area; Dybden indtil 417 Favne. Norman anfører 

 den ogsaa fra "Lightning" Expeditionen. Arten erforøvrigt 

 kun kjendt fra de britiske Øer og den norske Kyst. 



77. Diastylis spinulosa. Heller. 



Af denne smukke under den osterrigsk-unuarske Nord- 

 polexpedition opdagede Art toges enkelte Exemplarer i

Examples of this spedes, a very common one off the 

 coast of Norway, and occurring most abundantly in certain 

 localities, «ere tåken on the Expedition in the Saltenfjord. 

 the Kjosen, aud the Porsangerfjord; moreover, in Advent Bay, 

 Spitzbergen, as also at Stations 18, 192, and 357 — thetwo 

 former located in the sea ofl' the Norwegian coast, the 

 latter west of Spitzbergen; depth reaching 649 fathoms. 



Though the animal occurs as far south as the coast 

 of Pommerania, it must unquestionably be regarded, in 

 origin at least, as an Arctic form, its range of distribution 

 extending northward to Greenland, the east coast of America, 

 the Siberian Polar Sea. and the Kara Sea,. Besides. two 

 of the Stations at which it svas observed on the Norwegian 

 Expedition belong to the cold area. 



75. Diastylis cornuta. Boeck. 



This species, likewise a very common one off the 

 Norwegian coast. was observed on the Expedition at Husø ; 

 depth 80 — 100 fathoms. It is obviously a. more southern 

 form. being distributed to the British Islands (D. bicornis 

 Sp. Bate) and the west coast of France (Fischer). Norman 

 records the animal, too, from the "Porcupine" Expedition, 

 as occurring at a great depth in the Atlantic. The form 

 described by the same naturalist as D. strigata, I regard 

 as the fully developed male of the present species. 



76- Diastylis echinata. Sp. Bate. 



Besides Husø, this species was observed on the Ex- 

 pedition at 2 Stations off the West Coast of Norway (Stats. 

 31 and 124). both belonging to the eld area; depth reach- 

 ing 417 fathoms. Norman also records the form from the 

 "Lightning" Expedition. Kor the rest. the animal is known 

 only from the British Islands and the coast of Norway.

 Hungarian Expedition. a few individuals were tåken in the
