Form, idet dot successivt udvides mod Enden, der gaar ud 
i en temmelig stor omboiet mod taffte Forster besat Lap. 
Saavel dette som det foregaaende Led er desuden forsynet 
med et bctydeligt Antal at eiendommelige, bageformigt oin- 
boiede Smaabarstcr, der rirneligvis tjener til at t'seste og 
holde i Situs de ydre /Eggemasser. Af de Led, der sam- 
menssetter det terminale Parti (Fig. 1 g), er det lste starst, 
skjandt ikke meget lsengere end det derpaa falgende, og 
overalt tset baaret. De 4 falgende Led aftager successivt 
lidt i Starrelse og er alle temmelig sammentrykte samt stserkt 
indknebne ved Basis. 1 Inderlcanten bar disse Led en re- 
gelmsessig Rad af smalt lancctformige Tomer, der ved stserk 
Forstarrelse (Fig. 1 h) viser sig at vsere sserdeles tint saug- 
takkede i sit ydre Parti, medens de nan-mere Basis bar i 
hver Kant en Del betydelig grovere tandformige Fremspring. 
Endekloen er betydelig kortere end sidste Led og tint tan-

navnlig i sit ydre Parti, tset haarede, bvorimod lignende 
pigformige F ortsatser som bos foregaaende Slsegt ganske

midterste omtrent saa langt som de 2 avrigo tilsammen og 
noget kolleformigt opsvulmet i Enden. Laarleddet' er for- 
holdsvis stort, skjandt neppe dobbelt saa langt som Hoftc- 
partiet, og bos Hunnen noget opsvulmet paa jGrund af de

end Laarleddet, bvorimod 2det Lsegled er adskilligt lsengere 
og betydelig smalere. Tarsalleddet (se Fig. 1 i) er sserdeles 
kort, bredere end langt og af trekantet Form; paa Yder- 
siden gaar det ud i en lideu tilspidset Lap og har langs 
den stserkt buede Inderkant en tset Rad af Torner, der til- 
tager i Lsengde udad. Fodleddet er kraftigt udviklet og 
noget krummet, med Inderkanten tydeligt indbugtet i Midten 
og ved Basis noget pladeformigt udvidet saint her bevsebnet 
med en Rad af 6 eller 7 temmelig forlamgede og tset sam- 
mentrsengte Torner. Den avrige Del af Inderkanten barer 
ogsaa en Rad at Torner, men som er meget mindre, og langs 
Yderkanten og ved Spidsen er Led let tset baaret. Ende- 
kloen er betydelig kortere end Fodleddet, temmelig tynd og 
leformigt krummet, uden det miudste Spor af Rikhter. 
Dyrets Farve er i levende Tilstand ensformig gul- 
hvid. 
Forekomst. Af donne interessante Form blev 4 fuld- 
voxne Exemplarer indsamlede under Nordbavs Expeditionens 
sidste Togt. Exemplarerne var fra 3 forskjellige Stationer, 
nemlig Stat. 290, 362, 363. Af disse er den lste beliggende 
omtrent midtveis mellem Finmarken og Beeren Eiland. de 
2 ovrige i Havet udenfor Spitsbergens Nordvestkyst; Dyb- 
den fra 191 til 459 Favne. 
Udbredning. Arten er utvivlsomt at betragte som 
en segte arktisk Form. Foruden i Nordliavet forekommer 
taken together, and characterised, too, by a somewhat deviating 
form, expanding successively, as it does, towards the extremity, 
which projects in a rather large, recurved, with dense setae 
beset lobe. Both this and the preceding joint are, moreover, 
provided with a considerable number of small peculiar recurved 
hamate bristles, serving probably to attach and retain in situ - 
the outer egg-masses. Of the joints composing the terminal 
part (tig. 1 g), the I st is largest, although not much longer 
than the one succeeding it, and everywhere densely hairy. 
The 4 following joints diminish successively a little in size, 
and are all rather compressed, as also very much constricted 
at the base. On the inner edge these joints have a regular- 
series of slender lanceolate spines, which, under a strong mag- 
nifier (fig. 1 h), appear most finely serrated in their outer 
part, whereas, nearer' the base, they have on each edge a 
number of considerably coarser dentiform projections. The 
terminal claw is a good deal shorter than the last joint, 
and finely dentated on the inner edge. 
The ambulatory legs (see fig. 1) are comparatively ro- 
bust in structure and not quite 3 times as long as the body. 
They are, more especially in their outer part, densely 
hairy, whilst spiniform processes, similar to those in the 
preceding geuus, are altogether wanting. Of the 3 joints 
composing the coxal region, the mesial one attains about the 
length ot the 2 others taken together, and is somewhat 
clavately swollen at the extremity. The femoral joint is 
comparatively large, although hardly twice as long as the 
coxal part, and in the female somewhat swollen owing to 
the eggs developing within it. The 1st tibial joint is 
shorter than the femoral joint, whereas the 2nd tibial joint 
is considerably longer and much narrower. The tarsal 
joint (see fig. 1 i) is exceedingly short, broader than long, and 
triangular in form ; on the outer side it projects as a small 
accumulated lobe, and exhibits along the arcuate inner edge 
dense series of spines increasing in length outwards. The 
propodal joint is powerfully developed and somewhat curved, 
with the inner edge distinctly emarginate in the middle, and 
at the base somewhat lamellarly expanded, as also armed in 
that part with a series of 6 or 7 rather elongated and den- 
sely crowded spines. The upper part of the inner edge 
also bears a series of spines, but much smaller, and along 
the outer edge and at the point the joint is densely hairy. 
The terminal claw is much shorter than the propodal joint, 
rather thin and falciform curvate, without exhibiting the 
slightest trace of auxiliary claws. 
The colour of the animal in the living state is a uni- 
form yellowish white. 
Occurrence. Of this interesting form only 4 adult 
examples wore collected on the last cruise of the North 
Atlantic Expedition. The specimens were from 3 different 
Stations, viz. Stats. 290, 362, 363. The 1st of these lies 
about midway between Finmark and Beeren Island, the 
other 2 in the ocean off the north-west coast of Spitsbergen ; 
depth from 191 to 459 fathoms. 
Distribution. The species must unquestionably be re- 
garded as a true Arctic form. Besides in the Norwegian Sea,
