(se Fig. 2 b, 2 g) kjendelig kraftigere udviklede og navnlig
5te Lecl af betydelig Størrelse, noget krummet og i sit
ydre Parti forsynet med en stærk Opsvulmning besat med
lange og tætte Borster. Ogsaa Endedelens lste Led er
forholdsvis større og bredere end hos Hunnen.
Rand-tomerne (Fig. 2 h) er hos begge Kjon bredt lancetformige
og utydeligt crenulerede i Kanterne, med det yderste Parti
glat. Endekloen er fint tandet i den ene Kant.
Gangfødderne (se Fig. 2) viser ogsaa hos denne Art
en temmelig robust Bygning, men afsmalnes kjendelig mere
mod Enden og er besatte med længere og stærkere Haar.
De er omtrent 3’/a Gang længere end Legemet og har
Laarleddet hos Hunnen meget bredt og noget sammentrykt
fra Siderne, hos Hannen (Fig. 2 k) betydelig smalere og
i den indre Kant forsynet med en Rad af talrige (omkring
1-4) smaa Knuder, der giver denne Kant et fint crenuleret
Udseende. 2det Lægled er omtrent 3 Gange længere end
det terminale Afsnit og afsmalnes temmelig stærkt mod
Enden. Tarsalleddet (se Fig. 2 i) er noget længere 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
Torner, der dog kun indtager den indre Halvpart af
Leddet, og hvoraf de yderste er af betydelig Længde.
Endekloen er forholdsvis længere og tyndere end hos foregaaende
Art og noget leformigt tilskjærpet. Derimod er Bikløerne
yderst smaa.
De ydre Ægmasser (se Fig. 2 b), der altid kun er
tilstede i et enkelt Par, er af betydelig Størrelse og
uregelmæssig kugledannede, med talrige Æg af middels Størrelse
og, paa Grund af det gjensidige Tryk, mere eller mindre
kantet Form.
Dyrets Farve er ialmindelighed skidden graa, gaaende
over i det brunlige! Ofte er imidlertid Legemet saa tæt
besat med fremmede Dele. at Farven er vanskelig at
bestemme. Ikke sjelden har jeg til Fødderne fundet fæstet
Bryozoer, Anneliderør, Hydroider og andre Pseudoparasiter.
Forekomst. Ved vore Kyster har jeg kun observeret
denne Art i den arktiske Region, hvor den imidlertid paa
sine Steder, f. Ex. ved Vadsø, 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 kariske Hav har jeg
havt Anledning til at undersøge talrige Exemplarer,
indsamlede under Nordenskjolds Expedition.
Udbredning. Arten synes at have en vid
Udbredning i de arktiske Have. Foruden de ovenomtalte Steder,
er den observeret ved arktisk Nordamerika (Bell), Grøn-
limbs (see fig. 2 b, 2 g) are appreciably more powerfully
developed, the 5th joint in particular being of
considerable 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 larger and broader than in the female. The
marginal spines (fig. 2 h) are, in both sexes,
broad-lanceolate 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
appreciably more towards the extremity, and are beset with
longer and stiffer hairs. They are about 3’/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
crenulated 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
somewhat longer than broad, and does not form a distinct
lobe inwards. The propodal joint is more than twice as
long, and tapers successively towards the end. On its
inner edge this joint has 4 or 5 slender spines, which
occupy, 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 than in the
preceding species, and somewhat faleiformly sharpened. The
auxiliary 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 Norway 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
Expedition 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
Nordenskjöld’s Expedition.
Distribution. The species seems to be widely
distributed throughout the Arctic Seas. Besides in the
above - mentioned localities, it is recorded from Arctic
