Fig. 1 4), der navnlig paa den ubevægelige Finger er af
meget ulige Længde, idet større Tænder her temmelig
regelmæssigt afvexler med neppe halvt saa store. Begge
Fingre udmærker sig forøvrigt i høi Grad ved den
eiendommelige Maade, hvorpaa de ender. Den ubevægelige Finger
gaar nemlig ud i en særdeles stærkt, hageformigt
indad-krummet skarp Spids, medens den bevægelige omvendt
ender med en stump knudeformig Opsvulmning (se Fig. 1 d).
Folerne (Fig. 1 e) er overordentlig tynde og
for-længede, hvorfor de ialmindelighed viser en meget stærk
zigzag-formig Krumning. Det indbyrdes Længdeforhold af
Leddene skiller sig ogsaa kjendeligt fra samme hos de 2
foregaaende Arter. 2det Led er saaledes her betydelig
længere end 3die, hvorimod de 2 ydre Led er forholdsvis
mindre og smalere, omtrent af ens Størrelse og begge
til-sammentagne neppe længere end 3die Led. Som hos de
2 foregaaende Arter er disse Lemmer kun besatte med
meget korte og spredte Haar.
De falske Fødder hos Hannen (se Fig. 1 a) er
forholdsvis meget spinkle og lige udstrakte neppe længere end
Legemet. Af Leddene er det 5te størst og længere end
Endedelen. Bandtornerne (Fig. 1 t) er smalt
lancetfor-mige og grovt saugtakkede i Kanterne.
Gangfødderne (se Fig. 1) er meget spinkle og stærkt
afsmalnende mod Enden, samt næsten nøgne. De er
henimod 5 Gange længere end Legemet og har 2det Lægled
forholdsvis endnu stærkere forlænget end hos A7. gracilipes
og af særdeles smal lineær Form. Det terminale Afsnit
er neppe J/4 saa langt som 2det Lægled og bar Fodleddet
noget kortere end TarsaUeddet; begge Led er smalt lineære
og i den indre Kant bevæbnede med korte Torner, imellem
hvilke staar Grupper af meget finere saadanne.
Endekloen er betydelig kortere end Fodleddet, dog af kjendelig
spinklere Form end hos N. Strømii. Bikløerne er
forholdsvis smaa, neppe mere end ’/4 saa lange som selve
Kloen.
De ydre Ægmasser (se Fig. 1 a) er forholdsvis mindre
end hos de 2 foregaaende Arter, af kugledannet Form og
kun tilstede i et enkelt Par. Derimod er Æggene
kjendelig større end hos hine Arter.
Forekomst. Ved vore Kyster har jeg endnu ikke
observeret denne Art. Derimod toges den under
Nordhavs-Expeditionen i stort Antal paa mange forskjellige Punkter.
Den er noteret fra ikke mindre end 11 forskjellige
Stationer, nemlig: St. 18, 31, 48, 124, 164, 262, 275, 312,
315. 343. 363. Af disse ligger de 3 første i den sydligste
Del af det af os undersøgte Havstrøg, dels nærmere den
norske Kyst, dels nærmere Island (St. 48); de 2 følgende
Stationer ligger i Havet udenfor Nordlandskysten og Lofoten;
de øvrige 6 falder alle paa den nordlige Del af det af os
bereiste Havstrøg, dels i Østhavet (St. 262, 275), dels i
Naboskabet af Beeren Eiland og Spitsbergen; Dybden fra
appearance. The fingers are abont as long as the palm,
and both have, on the inner edge, numerous sharply pointed
teeth (see fig. 1 d), which, more particularly on the
immobile finger, are very unequal in length, as, here, largish
teeth alternate pretty regularly with others scarcely half
their size. Both fingers are prominently distinguished,
otherwise, by the peculiar way in which they terminate. The
immobile finger runs, thus, out into a very strongly
ungui-form incurvate sharp [joint, while the mobile one terminates,
on the contrary, in an obtuse tuberculiform swelling (see
fig. ld).’
The palpi (fig. 1 e) are remarkably slender and
elongated, and exhibit therefore, as a rule, a very prominent
zigzag-shaped curvature. The longitudinal relations of the
joints inter se differ, too, appreciably, from those in the 2
preceding species. Thus, the 2nd joint is considerably
longer than the 3rd, whereas the 2 outer joints are relatively
smaller and more slender, about equal in length, and both
taken together hardly longer than the 3rd joint. As in
the 2 preceding species, those limbs are only beset with
very short and scattered hairs.
The false legs in the male (see fig. 1 a) are relatively
very slender, and. when fully extended hardly longer than
the body. Of the joints, the 5th is the largest, and
longer than the terminal part. The marginal spines (fig.
I f) are narrow lanceolate, and coarsely serrated on the
edges.
The ambulatory legs (see fig. 1) are ver/slender, taper
rapidly towards the end, and are well-nigh bare. They
are nearly 5 times longer than the body, and have the
2nd tibial joint, relatively, still more elongate than in N.
gracilipes, and particularly narrow linear in form. The terminal
section is scarcely one-fourth as long as the 2nd tibial joint,
and has the propodal joint somewhat shorter than the
tarsal joint; both joints are narrow linear, and armed
on the inner edge with short spines between which are
groups of delicate spinules. The terminal claw is
considerably shorter than the propodal joint, but appreciably
slenderer than in N. Stfomii. The auxiliary claws are
comparatively small, hardly more than one-fourth as long
as the claw itself.
The outer egg-masses (see fig. 1 a) are relatively
smaller than in the 2 preceding species, are globular in
form and present only as a single pair. The ova, on the
contrary, are perceptibly larger than in those species.
Occurrence. I have not, as yet, observed this Species
on the coasts of Norway. The animal was, however, met
with on the North-Atlantic Expedition in great abundance
at many different places. It is noted from not less than
II different Stations, viz: Sts. 18, 31, 48, 124, 164,262,
275, 312, 315, 343, 363. Of these, the 3 first lie in the
southernmost part of the ocean tract investigated by the
Expedition, partly not far from the Norwegian coast and partly
not far from Iceland (St. 48); the 2 following Stations lie
in the seas off the coasts of Nordland and Lofoten; the
remaining 6 are all located in the northern part of the ocean
tract explored, 2 in the Barents’ Sea (Sts. 262, 275) and
