Saxlemmerne (se Fig- 2 a, 2 b) er ualmindelig smaa 
og svagtbyggede, med Skaftet smalt cylindriskt og naesten 
dobbelt saa laugt som Haanden. Derme sidste (1 ig- 2 d) 
er neppe bredere end Skattet, og har Palmen noget na-i 
cylindrisk samt tommelig sparsomt besat med korte Haar. 
Fingreue er lioget kortere end Palmen, staerkt krummede 
i Enden. og i Inderkanten bevsebnede med et ikke meget 
betydeligt Antal af forholdsvis smaa, ensformigt udviklede 
Sidetaender. 
Folerne (Fig. 2 e) overgaar kun lidet Saxlemmerne 
i Laengde og er som disse kun forsynede med meget smaa 
Haar. Af Leddene er det 2det lsengst, men adskilligt smalere 
end 3die, der er lidt laengere end de 2 yderste Led til- 
sammen. Sidste Led er ualmindelig lidet og af oval Form. 
De falske Fodder lios Hannen (se Fig. 2 b) er omtrent 
1 / 4 lmngere end Legemet og temmelig kraftigt byggede. Af 
Leddene er 5te som smdvanlig storst. men neppe lmngere 
end Endedelen (Fig. 2 f). Randtornerne (Fig. 2 g) ei 
forholdsvis smaa, smalt lancetformige og grovt saugtakkede 
i Kanterne. 
Gangfpdderne (se Fig. 2) er vistnok meget staerkt 
forkengede, idet de, lige udstrakte, naesten er B Gauge 
lmngere end Legemet, men har desuagtet et temmelig 
robust Udseende og afsmalnes kun meget ubetydeligt mod 
Enden. For det blotte 0ie synes de ganske nogne, men 
ved tilstraekkelig Forstprrelse viser de sig tset besatte i sin 
hele Laengde med overordeutlig smaa Haar. Af Leddene 
er Laarleddet og lste Lsegled naesten af ens Laengde, 
medens 2det Lfegled er betydelig laengere, dog neppe mere 
end 3 Gange saa langt som det terminate Afsnit. De 2 
Led, der sammensffitter dette Afsnit (Fig. 2 b), er begge 
kraftigt udvikledo og omtrent af ens Laengde. Fodleddet 
har i Inderkanten, foruden de fine Haar, der overalt be- 
klaeder disse Led, 6—7 staerke Torner. Endekloen er 
neppe mere end halvt saa lang som Fodleddet, men tem- 
melig kraftig og noget leformigt tilskjaerpet. Bikloerne 
er vel udviklede, naesten af Endeldoens halve Laengde. 
Ingen af de under Nordh. Expeditionen indsamlede 
Exemplarer havde ydre iEgmasser. Dr. Hansen har imid- 
lertid underspgt aegbaerende Individer og beskriver iEgmas- 
serne som forholdsvis store, af mere eller mindre kugle- 
dannet Form, og indeholdende talrige meget smaa iEg. 
Forekomst. 3 Exemplarer af denne eiendommelige 
Art blev under Nordh. Expeditionens sidste Togt tagne i 
Havet mellem Beeren Eiland og Spitsbergen (Stat. 315 
og 337) paa et Dyb af 146-180 Favne. Ved Norges 
Kyster er den hidtil ikke observeret. 
Udbredning. Arten er udbredt til Barents Seen 
(Hoek), det kariske Hav (Hansen) og Davisstraedet (den 
samme), og er saaledes utvivlsomt at betragte som en 
aegte arktisk Form. 
The chelifori (fig. 2 a, 2 b) are remarkably small 
and feeble in structure, with the scape narrow cylindiic 
and well-nigh twice as long as the hand. The latter 
(fig. 2 d) is scarcely hroader than the scape, and has the 
palm very nearly cylindric and rather sparingly beset with 
short hairs. The fingers are somewhat shorter than the 
palm, strongly bent at the tips, and armed on the innei 
edge with a not very considerable number comparatively 
small lateral teeth, uniform in development. 
The palpi (fig. 2 e) exceed the chelifori but little 
in length, and are, like those limbs, provided only with 
very delicate hairs. Of the joints, the 2nd is the longest, 
but considerably narrower than the 3rd, which is a little 
longer than the 2 outermost joints taken together. Tim 
last joint is remarkably small and oval in lorm. 
The false legs in the male (see fig. 2 b) are about 
one-fourth longer than the body and rather powerful in 
structure. Of the joints, the 5th is as usual the largest, 
but scarcely longer than the terminal part (fig. 2 f). 
The marginal spines (fig. 2 g) are comparatively small, 
narrow-lanceolate and coarsely serrate on the edges. 
The ambulatory legs (see fig. 2) are indeed very much 
elongated, measuring, when fully extended, nearly 5 times 
the length of the body, but have, nevertheless, a rather 
robust appearance and taper but very slightly towards 
the extremity. To the naked eye they appear to be quite 
bare, but when sufficiently magnified they are found to be 
densely beset throughout their entire length with exceedingly 
minute hairs. Of the joints, the femoral joint and the 1st tibial 
joint are almost equal in length, whereas the 2nd tibial joint 
is considerably longer, though hardly more than 3 times as 
long as the terminal section. The 2 joints which compose 
this section (fig. 2 h) are both powerfully developed, and 
about equal in length. The propodal joint bears on the 
inner edge, besides the delicate bristles with which these 
joints are everywhere covered, 6 or 7 strong spines. The 
terminal claw is hardly more than halt as long as the 
propodal joint, but rather powerful and somewhat falci- 
formly sharpened. The auxiliary claws are well developed, 
almost half the length of the terminal claw. 
None of the specimens collected on the North- Atlantic 
Expedition had outer egg-masses. Dr. Hansen has, how- 
ever, examined ovigerous individuals, and describes the egg- 
masses as comparatively large, more or less globular in 
form, and containing numerous very minute ova. 
Occurrence. The 3 examples of this peculiar species 
were taken on the last cruise of the North-Atlantic Expe- 
dition, in the ocean between Beeren Eiland and Spitsbergen 
(Stats’. 315, 337), at a depth of 146—180 fathoms. On the 
coasts of Norway the animal has not hitherto been observed. 
Distribution. The range of the species extends to 
Barents’ Sea (Hoek), the Kara Sea (Hansen), and Davis’ 
Straits (same author), and hence the animal must unques- 
tionably be regarded as a true Arctic form.
