EmleUloen er tydeligt udviklet, skjøndt ikke af nogen
betydelig Længde og ganske glat.
Gangfødderne (se Fig. 1) er omtrent dobbelt saa
lange som Legemet og idethele af temmelig kraftig
Bygning, kun lidet afsmalnende mod Enden. De 3 Hofteled
er korte og tykke, næsten terningformige og omtrent af
ens Størrelse. Laarleddet er omtrent 3 Gange saa langt
som Hoftepartiet og kun lidet opsvulmet. De 2 Lægled
er betydelig kortere og ikke meget forskjellige indbyrdes,
begge simpelt cylindriske. Endepartiet (Fig. 1 d) er noget
kortere end sidste Lægled og betydelig smalere. Af dets
2 Led er det lste (Tarsalleddet) betydelig større end
Fodleddet og begge ganske simple, uden anden Bevæbning
end de samme smaa mikroskopiske Torner, der ogsaa
bedækker den øvrige Del af Fødderne. Endekloen er
adskilligt kortere end Fodleddet, fuldkommen lige og sylformigt
tilspidset. Af Bikloer er der intet Spor at opdage.
Farven er hos det levende Dyr gulrød, noget mere
intens ved Enden af Leddene.
Forekomst. Det ovenfor beskrevne Individ toges
under Expeditionens lste Togt i Havet V af Storeggen
(Ståt. 18) paa et Dyb af 412 Favne.
Udbredning. Arten synes at have en vid Udi
Hedning i de arktiske Have. Den blev først beskrevet af
Sabine fra Polarhavet mellem Grønland og Nordamerika
og er senere noteret af Jarzynsky fra den murmanske
Kyst, af Hoek fra flere Punkter i Barentssøen samt fra
Færo-Shellands-Renden (Triton’s Expedition), af Miers fra
Frantz Josephs Land, af Hansen fra det kariske Hav og
fra Nord-Grønland; endelig af Stuxberg fra det sibiriske
Ishav. Ifølge denne Udbredning maa Arten siges at være
circumpolar, og skjøndt den er observeret saa langt Syd
som til den 60de Bredegrad, er den utvivlsomt at betragte
som en ægte arktisk Form, da hine sydlige Stationer alle
tilhører den kolde Area.
short, compressed spines. The terminal claw is distinctly
developed, although not of any considerable length, and
quite smooth.
The ambulatory legs (see fig. 1) are about twice as
long as the body and altogether of pretty powerful
structure, only little tapered towards the extremity. The 3
coxal joints are short and thick, almost quadrate, and
about equal in size. The femoral joint is about 3 times
as long as the coxal part and only little tumefied. The
2 tibial joints are considerably shorter and not very
different from each other, both plain cylintlric. The terminal
part (fig. 1 d) is somewhat shorter than the last tibial
joint and considerably narrower. Of its 2 joints the 1st
one (the tarsal joint) is considerably larger than the
propodal joint, and both are quite plain, without any other
armature than the same small microscopical spines as
also cover the remaining portion of the legs. The
terminal claw is considerably shorter than the propodal joint,
perfectly straight, and pointed like an awl. No trace of
auxiliary claws can be discovered.
The colour in the living animal is yellow-red,
somewhat more intense at the extremity of the joints.
Occurrence. The individual described in the
foregoing was taken on the 1st cruise of the Expedition, in
the ocean W. of the Storeggen bank (Ståt. 18) at a depth
of 412 fathoms.
Distribution. The species seems to have a wide
distribution in the Arctic seas. It was first described by
Sabine from the Polar Sea between Greenland and North
America, and is subsequently recorded by Jarzynsky from the
Murruan coast, by Hoek from several points in the Barents
Sea and from the Faroe—Shetland Channel (Triton’s
Expedition), by Miers from Frants Josephs Land, by Hansen
from the Kara Sea and from North Greenland, and finally,
by Stuxberg from the Siberian Polar Sea. According
to that distribution, the species must be said to be
circumpolar. and although it has been observed as far south
as the 60th parallel of latitude, it must, indubitably, be
considered as a genuine Arctic form, as those southern
stations all pertain to the cold area.
