Fig. 1 cl), der navnlig paa den ubeveegelige Finger er af 
meget ulige Lamgde, idet storre T ten der her temmelig 
regelmaessigt afvexler med neppe halvt saa store. Begge 
Fingre udrnasrker sig forpvrigt i hoi Grad ved den eiendom- 
melige Maade. hvorpaa de ender. Ben ubevaegelige Finger 
gaar nemlig ud i en sserdeles stserkt, hageformigt indad- 
krummet skarp Spids, medens den bevsegelige omvendt 
ender med en stump knudeformig Opsvulmning (se Fig. 1 d). 
Folerne (Fig. 1 e) er overordentlig tynde og for- 
lsengede, hvorfor de ialmindelighed viser en meget stserk 
zigzag-formig Krumning. Det indbyrdes Lsengdeforhold af 
Leddene skiller sig ogsaa kjendeligt fra samme hos de 2 
foregaaende Arter. 2det Led er saaledes her betydelig 
laengere end 3die, hvorimod de 2 ydre Led er forholdsvis 
mindre og smalore, omtrent af ens Stprrelse og begge til- 
sammentagne neppe lmngere end 3die Led. Som hos de 
2 foregaaende Arter er disse Lemmer kun besatte med 
meget korte og spredte Haar. 
De falske Fodder hos Hannen (se Fig. 1 a) er for- 
holdsvis meget spinkle og lige udstrakte neppe lmngere end 
Legemet. Af Leddene er det 5te storst og lsengere end 
Endedelen. Rand torn erne (Fig. 1 f) er smalt lancetfor- 
mige og grovt saugtakkede i Kanterne. 
Gangfpdderne (se Fig. 1) er meget spinkle og stserkt 
afsmalnencle mod Ender, samt naesten nogne. De er hen- 
imod 5 Gange lmngere end Legemet og bar 2det Lrngled 
forholdsvis endnu stserkere forlaenget end hos N. gracilipes 
og af sserdeles smal lineser Form. Det terminale Afsnit 
er neppe 1 / 4 saa langt som 2det Lsegled og bar Fodleddet 
noget kortere end Tarsalleddet ; begge Led er smalt linesere 
og i den indrc Kant bevsebnede med korte Torner, imellem 
hvilke staar Grupper af meget finere saadanne. Ende- 
kloen er betydelig kortere end Fodleddet, clog af kjenclelig 
spinklere Form end hos N. Strmiii. Bikloerne er for- 
holdsvis smaa, neppe mere end */ 4 saa lange som selve 
Kloen. 
De ydre iEgmasser (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 iEggene kjen- 
delig storre end hos hine Arter. 
Porekomst. 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 1 1 forskjellige Sta- 
tioner, nemlig: St. 18, 31, 48, 124, 164, 262, 275, 312, 
315, 343, 363. Af disse ligger de 3 forste i den syclligste 
Del af det af os underspgte Havstr 0 g, dels nsermere den 
norske Kyst, dels naermere Island (St. 48); de 2 folgende 
Stationer ligger i Havet udenfor Nordlandskysten og Lofoten ; 
de pvrige 6 falder alle paa den nordlige Del af det af os 
bereiste Havstrog, dels i Gsthavet (St. 262, 275), dels i 
Naboskabet af Beeren Eiland og Spitsbergen ; Dybden fra 
appearance. The fingers are about 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 im- 
mobile finger, are very unequal in length, as, here, largish 
teeth alternate pretty regularly with others scarcely half 
their size. Both fingers are prominently distinguished, other- 
wise, by the peculiar way in which they terminate. The 
immobile finger runs, thus, out into a very strongly ungui- 
form incurvate sharp point, while the mobile one terminates, 
on the contrary, in an obtuse tuberculiform swelling (see 
fig. 1 d). 
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 very 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. gra- 
dlipes, 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 con- 
siderably shorter than the propodal joint, but appreciably 
slenderer than in N. Stromii. 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 Ex- 
pedition, 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 re- 
maining 6 are all located in the northern part of the ocean 
tract explored, 2 in the Barents’ Sea (Sts. 262, 275) and
