(se Fig. 2 b, 2 g) kjendelig kraftigere uclviklede og navnlig 
5te Led -af betydelig Storrelse, noget krummet og i sit 
ydre Parti forsynet med en staerk Opsvulmning besat med 
lange og tsette Burster. Ogsaa Endedelens lste Led er 
forholdsvis sturre og bredere end hos Hunnen. Rand- 
tornerne (Fig. 2 k) er hos begge Kjon bredt lancetformige 
og utydeligt crenulerede i Kanterne, med det yderste Parti 
glat. Endekloen er fint tandet i den ene Kant. 
. Gangfodderne (se Fig. 2) riser ogsaa hos denne Art, 
en temmelig robust Bygning, men afsrualnes kjendelig mere 
mod Enden og er besatte mea lsengere og stserkere Haar. 
Do er omtrent 3 1 / s Gang ltengere end Legemet og har 
Laarleddet hos Hunnen meget bredt og noget sammeutrykt 
fra Siderno, hos Hannen (Fig. 2 k) betydelig smalere og 
i den indre Kant forsynet med en Rad af talrige (omkring 
14) smaa Knuder, der giver denne Kant et fint crenuleret 
Udseende. 2det Lsegled er omtrent 3 Gauge kengere end 
det terminale Afsnit og afsmalnes temmelig steerkt mod 
Enden. Tarsalleddet (se Fig. 2 i) er noget lsengere end 
bredt og danner ikke nogen tydelig Lap indad. Fodleddet 
er mere end dobbelt saa langt og afsmalnes successivt mod 
Enden. I den indre Kant har dette Led 4 — 5 tynde 
Tomer, der dog kun indtager den indre Halvpart af Led- 
det, og hvoraf de yderste er af betydelig Lsengde. Ende- 
kloen er forholdsvis lsengere og tyndere end hos foregaaende 
Art og noget leformigt tilskjserpet. Derimod er Bikfoerne 
yderst smaa. 
De ydre JEgmasser (se Fig. 2 b), der altid kun er 
tilstede i et enkelt Par, er af betydelig StUrrelse og uregel- 
msessig kugledannede, med talrige JEg af middels Storrelse 
og, paa Grand af det gjensidige Tryk, mere eller mindre 
kantet Form. 
Dyrets Farve er ialmindelighed skidd en graa, gaaende 
over i det brunlige. Ofte er imidlertid Legemet saa tret 
besat med fremmede Dele, at Farven er vanskelig at be- 
stemme. Ikke sjelden har jeg til Fpdderne fundet fsestet 
Bryozoer, Anneliderflr, Hydroider og andre Pseudoparasiter. 
Forekomst. Ved vore Kyster har jeg kun obsei'veret 
denne Art i den ai'ktiske Region, hvor den imidlertid paa 
sine Steder, f. Ex. ved Yadso, er temmelig hyppig paa 
50 — 100 F. D. Under Nordhavs-Expeditionen toges den 
paa ikke mindre end 12 forskjellige Stationer. Af disse 
ligger en (St. 48) 0 af Island, en anden (St. 223) S af 
Jan Mayen, 6 Stationer (St. 262, 267, 270, 273, 275, 
290) i Havet N og 0 af Finmarken, endelig 4 Stationer 
(St. 326, 336, 338, 363) i Havet om Spitsbergen ; Dybden 
fra 70 til 299 F. Ogsaa fra det kai’iske Hav har jeg 
havt Anledning til at undersoge talrige Exemplarer, ind- 
samlede under Nordenskjolds Expedition. 
Udbredning. Arten synes at have en vid Udbred- 
ning i de arktiske Have. Foraden de ovenomtalte Steder, 
er den observeret ved arktisk Nordamerika (Bell), Gron- 
limbs (see fig. 2 b, 2 g) are appreciably more powerfully 
developed, the 5th joint in particular being of consider- 
able size, somewhat curved, and furnished in its outer 
part with a prominent tumefaction beset with long and 
dense bristles. Also the 1st joint of the terminal part 
is relatively lai’ger and broader than in the female. The 
marginal spines (fig. 2 h) are, in both sexes, broad-lance- 
olate and indistinctly crenulated on the edges, with the 
outermost part smooth. The terminal claw has one of 
the edges finely dentate. 
The ambulatory legs (see fig. 2) exhibit, also, in 
this species a rather robust structure, but taper appreci- 
ably more towards the extremity, and are beset with 
longer and stiffer hairs. They are about 3 l / 2 times longer 
than the body and have the femoral joint in the female 
very broad and somewhat compressed from the sides, in 
the male (fig. 2 k) a good deal narrower, and furnished 
on the inner edge with a series of numerous (about 14) 
small nodules, which gives to this edge a delicately cren- 
ulated appearance. The 2nd tibial joint is about 3 times 
longer than the terminal section, and tapers rather abruptly 
towards the end. The tarsal joint (see fig. 2 i) is some- 
what longer than broad, and does not form a distinct 
lobe inwards. The propodal joint is more than twice as 
long, and tapei's successively towards the end. On its 
inner edge this joint has 4 or 5 slender spines, which oc- 
cupy, however, only the inner half of the joint, and of which 
the outermost are of considerable length. The terminal 
claw is relatively longer and thinner thau in the pre- 
ceding species, and somewhat falciformly sharpened. The 
auxiliai’y claws, on the other hand, are exceedingly small. 
The outer egg-masses (see fig. 2 b), present always 
as a single pair, are of considerable size and irregularly 
globiform, with numerous ova of moderate size and, owing 
to the reciprocal pressure, more or less angular. 
The colour of the animal is generally a dirty grey, 
bordering on brownish. Very often, however, the body 
is so coated with foreign substances as to render the 
colour difficult to determine. Not infrequently I have 
found attached to the legs, Bryozoa, the tubes of Annelids, 
Hydroids, and other pseudo-parasites. 
Occurrence. On the coasts of Noi’way I have 
only observed this species in the Arctic region, where 
however, in some localities, it is rather common at a 
depth of 50 — 100 fathoms. On the North Atlantic Ex- 
pedition it was taken at- as many as 12 different Stations, 
viz: 1 (St. 48) east of Iceland, 1 (St. 223) south of 
Jan Mayen, 6 (St. 262, 267, 270, 273, 275, 290) in the 
sea north and east of Finmark, and finally 4 (Sts. 326, 336, 
338, 363) in the sea round Spitzbergen; depth from 70 
to 299 fathoms. Also from the Kara Sea I have had 
opportunity of examining numerous specimens collected on 
Nordenskjold’s Expedition. 
Distribution. The species seems to be widely dis- 
tributed throughout the Arctic Seas. Besides in the 
above-mentioned localities, it is l’ecorded from Arctic
