Endeldoen er tydeligt udviklet, skjondt ikke af nogen be- | 
tydelig Lrengde og ganske glat. 
Gangfodderne (se Fig. 1) er omtrent dobbelt saa 
lange sotn Legemet og ideifhele af temmelig kraftig Byg- 
ning, kun lidet afsmalnende mod Enden. De 3 Hofteled 
er korte og tykke, rnesten terningformige og omtrent af 
ens Storrelse. Laarleddet er omtrent 3 Gauge saa langt 
som Hoitepartiet og kun lidet opsvulmet. De 2 Lsegled 
er betydelig kortere og ikke meget forskjellige indbyrdes, 
begge simpelt cylindriske. Endepartiet (Fig. 1 d) er noget 
kortere end sidste Liegled og betydelig smalere. Af dets 
2 Led er det Iste (Tarsalleddet) betydelig storre end 
Fodleddet og begge ganske simple, uden anden Bevadming 
end de samme smaa mikroskopiske Tomer, der ogsaa be- 
dsekker den ovrige Del af Fodderne. Endeldoen er adskil- 
ligt kortere end Fodleddet, fuldkommen lige og sylformigt 
tilspidset. Af Bikloer er der intet Spor at opdage. 
Farven er hos det levende Dyr gulrod, noget mere 
intens ved Enden af Leddene. 
Porekomst. Det ovenfor beskrevne Individ toges 
under Expeditionens lste Togt i Havet V af Storeggen 
(Stat. 18) paa et Dyb af 412 Favne. 
Udbredning. Arten synes at have en vid Udbred- 
ning i de arktiske Have. Den blev forst beskrevet af 
Sabine fra Polarhavet mellem Grpnland og Nordamerika 
og er senere noteret af Jarzynsky fra den murmanske 
Kyst, af Hoek fra Here Punkter i Barentss0en samt fra 
Faerp-Shellands-Renden (Triton’s Expedition), af Miers fra 
Frantz Josephs Land, af Hansen fra det kariske Hav og 
fra Nord-Grouland; endelig af Stuxberg fra det sibiriske 
Ishav. Ifolge denne Udbredning maa Arten siges at vsere 
circumpolar, og skjondt den er observeret saa langt Syd 
som til den 60de Bredegrad, er den utvivlsomt at betragte 
som en gegte arktisk Form, da bine sydlige Stationer alle 
tilhorer den kolde Area.

short, compressed spines. The terminal claw is distinctly 
developed, although not ot 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 struc- 
ture, only little tapered towards the extremity. The 3 
coxal joints arc 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 dif- 
ferent from each other, both plain cylindric. 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 pro- 
podal 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 ter- 
minal claw is considerably shorter than the propodal joint, 
perfectly sti'aight, and pointed like an awl. No trace of 
auxiliary claws can be discovered. 
The colour in the living animal is yellow-red, some- 
what more intense at the extremity of ihe joints. 
Occurrence. The individual described in the fore- 
going was taken on the 1st cruise of the Expedition, in 
the ocean W. of the Storeggen bank (Stat. 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 
Murman coast, by Hoek from several points in the Barents 
Sea and from the Faroe — Shetland Channel (Triton’s Ex- 
pedition), 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 cir- 
cumpolar, 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.
