74. Diastylis Rathkii, (Kroyer). 
Exemplarer af denne ved vore Xyster megel alminde- 
lige, paa sine Steder 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 forste beliggende i Havet 
udenfor vor Kyst, den sidste- Y af Spitsbergen; Dybden 
indtil 649 Favne. 
Skjondt Arten gaar sydlig til Pommerens Kyst, er 
den dog utvivlsomt at betragte som en oprindelig arktisk 
Form, da den er udbredt til Gronland, Nordamerikas 0st- 
kyst, Sibiriens Tshav og det kariske Hav. To af de Sta- 
tioner, hvor den under vor Expedition blev observeret, til- 
borer desuden den kolde Area. 
75. Diastylis cornuta, Boeck. 
Denne ved vore Xyster ligeledes meget almindelige 
Art observeredes under Expeditionen ved Huso paa 80 — 
100 Favnes Dybde. Den er aabenbart en mere sydlig Form 
°g udbredt til de britiske 0er ( D . Ucornis Sp. Bate) og 
Vestkysten af Frankrige (Fischer). Norman anforer den 
°gsaa fra Porcupine-Expeditionen som forekommende paa 
stort Dyb i Atlanterhavet. Den af samme Forfatter under 
Benmvnelsen D strigata beskrevne Form anser jeg for den 
fuldt udviklede Han af naarvmrende Art. 
76. Diastylis echinata, Sp. Bate. 
Foruden ved Huso blev denne Art under Expeditio- 
nen observeret paa 2 i Havet udenfor vor Yestkyst belig- 
gende Stationer (Stat. 31 og 124), begge tilhorende den 
kolde Area; Dybden indtil 417 Favne. Norman anforer 
ben ogsaa fra “Lightning” Expeditionen. Arten er forovrigt 
kun kjendt fra de britiske 0er og den norske Kyst. 
77. Diastylis spinulosa, Heller. 
Af denne smukke under den osterrigsk-ungarske Nord- 
Polexpedition opdagede Art toges enkelte Exemplarer i 
74. Diastylis Rathkii, (Kroyer). 
Examples of this species, a very common one off the 
coast of Norway, and occurring most abundantly in certain 
localities, were taken on the Expedition in the Saltenfjord, 
the Kjosen, and the Porsangerfjord; moreover, in Advent Bay, 
Spitzbergen, as also at Stations 18, 192, and 357 — the two 
former located in the sea off 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 was 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 Huso ; 
depth 80—100 fathoms. It is obviously a more southern 
form, being distributed to the British Islands (D. Ucornis 
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 TJ. strigata, I regard 
as the fully developed male of the present species. 
76. Diastylis echinata, Sp. Bate. 
Besides Huso, this species was observed on the Ex- 
pedition at 2 Stations off the Y7 est Coast of Norway (Stats. 
31 and 124), both belonging to the cold area; depth reach- 
ing 417 fathoms. Norman also records the form from the 
“Lightning” Expedition. For the rest, the animal is known 
only from the British Islands and the coast of Norway. 
77. Diastylis spinulosa, Heller. 
Of this beautiful species, discovered on the Austrio- 
Hungarian Expedition, a few individuals were taken in the
