Gangfodderne (se Fig. 1) er temmelig spinkle, naesten 
5 Gauge kengere end Legemet og besatte med korte, spredte 
Haar. 2det Hofteled er stserkt forlsenget, betydelig lsengere 
end de 2 ovrigc. tilsammen, Laarleddet temmelig stserkt 
opsvulrnet hos Hunnen, medens det lios Hannen er meget 
smalt og af lineaer Form, lste Lasglod er lidt og 2det do. 
l / 3 lsengere end Laarleddet og sserdeles spinkelt. Ende- 
partiet (Fig. 1 i) er ligeledes meget smalt, ikke fuldt halvt 
saa langt som 2det Laigled, og ligner noget samme hos 
N. longitarse. Tarsalleddet er ogsaa her temmelig forlsenget, 
dog forholdsvis kortere end hos hin Art. Fodleddet er 
ligeledes meget smalt, linesert og noget, skjondt ikke meget, 
kortere end Tarsalleddet; det er besat- langs Tnderkanten 
med talrige meget smaa, nsesten haarformige Torner, livoraf 
enkelte, fsestede i regelmaessig Afstand fra hinan'den, er 
ubetydelig stserkere. Endekloen er noget mere forlsenget 
end hos N. longitarse og gaar nd i en fin, noget buet 
Spids. BiklOerne er, som hos denne Art, meget smaa, 
neppe mere end 1 /b saa lange som Endekloen. 
De ydre ^Egmasser er forholdsvis meget smaa og 
ssedvanlig fsestede omkring 5te Led af de falske Fodder. 
.ZEggene er derimod kjendelig storre end hos foregaaende 
Art. 
Forekomst og Udbredning. Jeg har truffet denne 
meget distincte Art temmelig hyppig langs vor hele Vest- 
kyst, idetmindste til Lofoten, paa 50—100 F. D. Et 
enkelt Exemplar toges under Nordhavs-Expeditionens sidste 
Togt omtrent midtveis mellem Finmarken og Beeren Eiland 
(Stat. 290) paa 191 F. D. Paa andre Punkter er ikke 
denne Art blcven observeret, og det stiller sig saaledes 
noget tvivlsomt, hvorvidt den kan ansees som on segte 
arktisk Form.

The ambulatory legs (see fig. 1) are rather slender, 
almost 5 times as long as the body, and beset with short, 
scattered hairs. The 2nd coxal joint is greatly elongated, 
considerably longer than both the others taken together; 
the femoral joint a good deal swollen in the female, 
whereas in the male it is very slim, and linear in form. 
The 1st tibial joint is a little, and the 2nd joint a third, 
longer than the femoral joint and are exceedingly slender. 
The terminal part (fig. 1 i) is likewise very slim, not quite 
half as long as the 2nd tibial joint, and has some resem- 
blance to that of N. longitarse. The tarsal joint is also here 
rather elongated, though relatively shorter than in the species 
named. The propodal joint is likewise very slender, linear, 
and a little, though not much, shorter than the tarsal one; 
it is beset along the inner edge with numerous very small, 
well-nigh capilliform spines, a few of which, attached at 
regular intervals from each other, are inconsiderably stouter. 
The terminal claw is a little more elongated than in N. longi- 
tarse, and runs out in a fine, somewhat arcuated point. The 
auxiliary claws are, as in that species, very small, hardly 
more than one-fifth as long as the terminal claw. 
The outer egg-masses are relatively very small and. 
as a rule, are adherent round the 5th joint of the false legs. 
The eggs themselves are, on the other hand, appreciably 
larger than in the preceding species. 
Occurrence and Distribution. I have met with this 
very remarkable species pretty frequently along the whole 
of the West coast of Norway, at least as far north as 
Lofoten, at a. depth of 50 — 100 fathoms. A single specimen 
was taken on the last cruise of the North- Atlantic Expedition 
about midway between Finmark and Beeren Eiland (Stat. 
290) at a depth of 191 fathoms. In other localities this 
species has not been observed, and it is therefore somewhat 
doubtful whether the animal can be regarded as a true 
Arctic form.
