6 stærke Torner, fæstede til ligeiuange særskilte Afsatser.
Endekloen er noget mere end halvt saa lang som Fodleddet
og temmelig stærk. Bikløerne er vel udviklede, dog
adskilligt kortere end hos de 2 foregaaende Arter.
De ydre Ægmasser (se Fig. 3 e) er af uregelmæssig
kugledannet Fonn og fæstede omkring 4de Led af de
falske Fodder. De talrige Æg er omgivne af en fælles tynd
membranøs Kapsel.
Forekomst. Det ovenfor beskrevne Exemplar blev
taget under Nordenskjolds Expedition 1870 i Strædet
Matotschkin Sharr paa 10—15 F. D., Lerbund.
Udbredning. Arten er først beskreven af Krøyer
fra Grønland. Derimod er den hverken observeret ved
Norges eller Englands Kyster; thi Angivelserne om dens
Forekomst her beror ganske sikkert paa en Forvexling med
enten N. gracile eller ganske unge Exemplarer af en eller
anden af de øvrige Arter.
than in N. gracile, and has oil the inner edge (i strong
spines, each affixed to its separate ledge. The terminal
claw is a little more than half as long as the propodal joint
and rather powerful. The auxiliary claws are well
developed, though considerably shorter than in the 2 preceding
species.
The outer egg-masses (see fig. 3 e), affixed round the
4th joint of the false legs, have an irregular globular
form. The numerous ova are enclosed in common, in a
thin membranous capsule.
Occurrence. The specimen described above was
taken on Nordenskjold’s Expedition, 1876, in tiie Strait
of Matotschkin Sharr at a depth of 10—15 fathoms; clay
bottom.
Distribution. This species was first described by
Krøyer, from Greenland. It has not been observed,
however, either on the coasts of Norway or England, as all
statements of its occurrence there have unquestionably
arisen from confounding the animal with either N gracile
or quite young examples of some one or other of the
known species.

Artscharacter. Legemet noget mindre undersætsigt
end hos foregaaende Art, med temmelig lange, vel skilte
Sidefortsatser. Hovedsegmentet noget længere end de 2
følgende Segmenter tilsammen, Halsen vel begrændset og
smalere end Snabelen, Pandedelen temmelig stærkt
fortykket. Øieknuden forholdsvis lav, stumpt tilspidset i Enden.
Snabelen kortere end Hovedsegmentet. Saxlemmerne af
middelmaadig Størrelse, Haanden noget kortere end Skaftet,
aflang oval, Fingrene omtrent af Palmens Længde.
Folerne med 2det og 3die Led af ens Længde, sidste Led
noget længere end næstsidste. De falske Fødder hos
Hannen længere end Legemet, 4de Led kortere end 5te,
Endedelen omtrent af dette sidste Leds Længde, Randtoraerne
bredt lancetformige, med et Par stærke Tænder nærmere
Basis og det ydre Parti fint og regelmæssigt saugtakket.
Gangfodderne neppe 3 Gange længere end Legemet og
besatte med temmelig lange, men spredte Haar; Tarsalleddet
forlænget, lineært; Fodleddet lidt kortere, med omtrent 9
stærke Torner i Inderkanten; Endekloen noget mere end
halvt saa lang som Fodleddet, meget kraftig; Bikløerne
vel udviklede, af Endekloens halve Længde. Legemets
La-ngde 4"""; Spandvidde 34"’"’.

Specific Character. Body somewhat less thickset than
in the preceding species, with rather long, well separated
lateral processes. Cephalic segment somewhat longer than
the 2 succeeding segments taken together, neck well marked
off and more slender than proboscis, frontal part very
considerably tumified. Oculiferous tubercle comparatively
low, obtusely pointed at the extremity. Proboscis shorter
than cephalic segment. Chelifori of moderate size; hand
a trifle shorter than scape, oblongo-oval; fingers about the
length of palm. Palpi with 2nd and 3rd joints equal in
length, last joint somewhat longer than penultimate one.
False legs in male longer than body; 4th joint shorter than
5th; terminal part about the length of that (5th) joint,
marginal spines broadly lanceolate, with a pair of strong teeth
nearer the base, and the outer division finely and regularly
serrate. Ambulatory legs hardly 3 times longer than body
and beset with rather long, but scattered hairs; tarsal joint
prolonged, linear; propodal joint a trifle shorter, with about 9
strong spines on the inner edge; terminal claw somewhat
more than half as long as the propodal joint, very powerful;
auxiliary claws well developed, half the length of the
terminal claw. Length of body i’/.,""", extent 34""’.
