Snabelen (se Fig. 3 a, 3 b) er vel udviklet, dog
adskilligt kortere end Hovedsegmentet, og af den sædvanlige
cylindriske Form.

Saxlemmerne (ibid.) er forholdsvis spinkelt byggede,
med Skaftet smalt cylindriskt og omtrent af Snabelens
Længde. Haanden (Fig. 3 d) er noget kortere end Skaftet
og ligeledes forholdsvis spinkel, ganske svagt udvidet paa
Midten og besat med korte Haar. Fingrene er stærkt
forlængede, omtrent af Palmens Længde, og stærkt krummede
i sit ydre Parti, hvorfor Spidserne krydser hinanden, naar
Saxen er lukket.

Folerne (Fig. 3 e) er ligeledes ualmindelig smale og
forlængede, med 2det og 3die Led af ens Længde.
Ende-partiet er noget længere end 3die Led og har næstsidste
Led kun lidet kortere end sidste.

De falske Fodder hos Hannen (se Fig. 3 b) er mere
end ’/2 Gang længere end Legemet og har 4de og 5te Led
omtrent lige lange, medens Endedelen (Fig. 3 f) er
Adskilligt længere. Randtornerne (Fig. 3 g) er forholdsvis smaa,
forøvrigt af en lignende Bygning som hos de foregaaende
Arter. Ved Enderne af Leddene findes imidlertid enkelte
Torner af en simplere Form, paa hvilke de stærke basale
Tænder synes at mangle.

Gangfodderne (se Fig. 3) er overordentlig spinkle og
forlængede, mere end 5 Gange længere end Legemet og
besatte med korte, spredte Haar. 2det Hofteled er
adskilligt længere end de 2 øvrige tilsammen, og de 3 følgende
Led tiltager stærkt i Længde, saa at 2det Lægled næsten
er dobbelt saa langt som Laarleddet- Det terminale Afsnit
(Fig. 3 h) er meget smalt og noget mere end ’/s saa langt
som 2det Lægled. Tarsalleddet er stærkt forlænget, næsten
dobbelt saa langt som Fodleddet, og noget buet.
Fodleddet er noget smalere og lige, samt i Inderkanten kun besat
med yderst korte haarformige Torner; hos enkelte
Exemplarer sees dog paa Midten nogle faa (sædvanlig 4) noget
stærkere, tiltrykte Torner. ’Endekloen er forholdsvis kort,
kun lidet mere end halvt saa lang som Fodleddet, og
Bikløerne er meget smaa, neppe ’h saa lange som
Endekloen.

De ydre Ægmasser (se Fig. 3 b) er af
middelmaadig Størrelse, cylindrisk-kugleformige og sædvanligvis
fæstede omkring öte Led af de falske Fødder, undertiden
dog ogsaa paa 4de. En enkelt Gang har jeg paa hver af
de falske Fodder fundet ikke mindre end 3 særskilte
Æggemasser, 2 paa 4de og 1 paa 5te Led. Æggene er
forholdsvis betydelig mindre end hos N. Sluiteri.

Dyret er i levende Tilstand temmelig gjennemsigtigt,
med et blegt kjødrodt Anstrøg, især ved Enden af
Krops-segmenterne og Leddene paa Fødderne.

Forekomst. Jeg har truffet denne Art af og til
langs vor hele Kyst paa 20:—100 F. D. Under
Nordhavs-Expeditionen toges 4 Exemplarer udenfor Sydspidsen af
Spitsbergen (Ståt. 336) paa 70 F. D. Desuden har jeg

The proboscis (see fig. 3 a, 3 b) is well developed,
considerably shorter, however, than the cephalic segment,
and of the usual cylindric form.

The chelifori (ibid.) are comparatively slender in
structure, with the scape narrow cylindric and about
same length as the proboscis. The hand (fig. 3 d) is a
trifle shorter than the scape and is, also comparatively
slender, very slightly expanded in the middle, and beset
with short hairs. The fingers are exceedingly elongate,
well-nigh the length of the palm, and sharply curved in
their outer part; the points therefore cross each other
when the chela is shut.

The palpi (fig. 3 ei are also uncommonly slender
and elongate, with the 2nd and 3rd joints equal in length.
The terminal part is a trifle longer than the 3rd joint
with the penultimate joint only little shorter than the
terminal one.

The false legs in the male (see fig. 3 b) are more
than half as long again as the body, and have the 4th and
5th joints about uniform in length, while the terminal part
(fig. 3 f) is a good deal longer. The marginal spines
(fig. 3’g) are comparatively small, but similar in structure,
otherwise, to those in all-the preceding species. At the
ends of the joints there occur, however, a few spines of a
simpler form on which the strong basal teeth are
apparently awanting.

The ambulatory legs (see fig. 3) are extremely slender
and elongate, more than 5 times longer than the body, and
beset with short, scattered hairs. The 2nd coxal joint is
considerably longer than the 2 others taken together, and
the 3 succeeding joints increase rapidly in length, so that
the 2nd tibial joint is almost twice as long as the femoral one.
The terminal section ifig. 3 h) is very slender and
something more than ’h of the length of the 2nd tibial joint. The
tarsal joint is greatly elongated, nearly twice as long as
the propodal joint, and somewhat arcuate. The propodal
joint is a trifle slenderer, and straight, and beset along the
inner edge with only extremely short, capilliform spines; in
some specimens there are seen, however, in the middle, a few
(generally 4) somewhat stronger, adpressed spines. The
terminal claw is comparatively short, but little more than
half the length of the propodal joint, and the auxiliary claws
are very small, hardly ’/i the length of the terminal one.

The outer egg-masses (see fig. 3 1)1 are of moderate
size, cylindrical^ globular, and generally adherent round the
5th joint of the false legs, sometimes, however, on the 4th
one also. Once only did I find on each of the false legs
as many as 3 separate egg-masses, 2 on the 4th and 1 on
the 5th joint. The ova are, relatively, a good deal smaller
than in N. Sluiteri.

The animal is, in the living state, rather transparent,
with a pale carnation tint, especially at the end of the
body-segments and on the leg-joints.

Occurrence. 1 have now and again met with this
species at a depth of from 20—100 fathoms along the
whole coast of Norway. On the North Atlantic
Expedition, 4 specimens were taken off the southern extremity of
