6 stserke Torner, festede til ligemange sserskilte Afsatser. 
Endekloen er noget mere end halvt saa lang som Fodleddet 
og temmelig staerk. Bikloerne er vel udviklede, dog adskil- 
ligt kortere end hos de 2 foregaaende Arter. 
De ydre xEgmasser (se Fig. 3 e) er at uregelmsessig 
kugledannet Form og fiestede omkring 4de Led at de fal- 
ske Fodder. De talrige Mg er omgivne af en faelles tynd 
membranos Kapsel. 
Forekomst. Det ovenfor beskrevne Exemplar blev 
taget under Nordenskjolds Expedition 1876 i Strmdet 
Matotschkin Sharr paa 10 — 15 F. D., Lerbund. 
Udbredning. Arten er forst beskreven at Kroyer 
fra Grottland. Derimod er den hverken observeret ved 
Gorges eller Englands Xyster; 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 ovrige Arter.

Artscharacter. Legemet noget mindre underssetsigt 
end hos foregaaende ikrt, med temmelig lange, vel skilte 
Sidefortsatser. Hovedsegmentet noget lsengere end de 2 
folgende Segmenter tilsammen, Halsen vel begrfendset og 
smalere end Snabelen, Pandedelen temmelig stserkt fortyk- 
ket. Gieknuden forholdsvis lav, stumpt tilspidset i Enden. 
Snabelen kortere end Hovedsegmentet. Saxlemmerne at 
middelmaadig Storrelse, Haanden noget kortere end Skaftet, 
allang oval, Fingrene omtrcnt al Palmens Lamgde. ho-

Gangfodderne neppe 3 Gauge lsengere end Legemet og be- 
satte med temmelig lange, men spredteHaar; Tarsalleddet 
forlsenget, linemrt; Fodleddet lidt kortere, med omtrent 9 
stserke Torner i Inderkanten; Endekloen noget mere end 
halvt saa lang som Fodleddet, meget kraftig ; Bikloerne

than in N. gracile, and has on the inner edge 6 stiong 
spines, each affixed to its separate ledge. The ter niinal 
claw is a little more than half as long as the propodal joint 
and rather powerful. The auxiliary claws are well devel- 
oped, 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 Nordenskj eld’s Expedition, 1876, in the Strait 
of Matotschkin Sharr at a depth of 10 — 15 fathoms; clay 
bottom. 
Distribution. This species was first described by 
Kroyer, from Greenland. It has not been observed, how- 
ever, 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.

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. Oculiterous 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, mar- 
ginal 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 4 1 / 2 , "“, extent 34““.
