som hos foregaaende Art og er som hos denne ofte tilstede

Forekomst. Yed vore Kyster har jeg kiln observeret 
denne Art i den arktiske Region, saaledes ved Tromso. 
Under Nordh. Expeditionen toges den typiske Form ikke 
ualmindelig ved Norske 0er, Nordvestsiden af Spitzbergen, 
paa 10 — 30 F. D. Desuden indsamledeg Exemplarer af 
Varieteten „abyssicola“ paa folgende Havstationer : Stat. 
164, 336, 343, den fqrste beliggende udenfor Lofoten, de 
2 pvrige Syd af Spitsbergen; Dybden fra 70 til 743 Favne. 
Ogsaa fra Nordenskjolds Expedition 1875 bar jeg havt 
nogle faa Exemplarer til Undersegelse, indsamlede dels i 
Striedet Matotshkin Scliarr dels ved Cap. Grebeni ; Dybden 
•2 — 14 Favne. 
Udbredning. Arten er udbredt til Grpnland (Krpyer), 
0stkysten af Nordamerika (Wilson), Barents Seen (Hoek) 
og det kariske Hav (Hansen). Derimod er jeg tilboielig 
til at anse Angivelserne om dens Forekomst lsengere syd 
(i Nordsoen og ved Englands Kyster) som beroende paa en 
Forvexling med andre nserstaaende Arter.

Artscbaracter. Legemet sterdeles spinkelt, med vidt 
adskilte forlsengede Sidefortsatser. Hovedsegmentet laengere 
end de 3 folgende Segmenter tilsammen, med sterdeles smal 
og forlaenget Hals, Pandedelen kun lidet udvidet. 0ieknu- 
den stserkt ophoiet, Enden udtrukket i en konisk Spids. 
Snabelen vel udviklet, noget kortere end Hovedsegmentet. 
Saxlemmerne svagere end hos foregaaende Art, Haanden 
neppe saa lang som Skaftet. lidt udvidet mod Enden, Fin- 
grene ltengere og mere krummede end hos N. yrossipes, 
nsesten af Palmens Lamgde. Folerne meget spinkle, 2det 
og 3die Led af ens Lamgde, sidste Led kun ubetydeligt 
lsengere end nsestsidste. De falske Fodder hos Hannen 
nsesten dobbelt saa langc som Legemet, 4de Led lidt lsen- 
gere end 5te, Endedelen kortere end dette Led, Randtor- 
The outer egg-masses (see fig. 2) are about as in the 
preceding species, and, as in that form, often occur in 
double the usual number on each of the false legs. 
Occurrence. On the coasts of Norway I have ob- 
served this species only in the Arctic region, for inst., at 
Tromso. On the North Atlantic Expedition, the typical 
form was not infrequently taken off the Norway Islands, 
the north-west coast of Spitzbergen, in depths of 10 — 30 
fathoms. Specimens of the variety „abyssicola“ were 
further collected at the following ocean-stations : Stat. 164, 
336, 343, the first lying off Lofoten, the 2 others south of 
Spitzbergen: depth from 70 to 743 fathoms. Also from 
N or denskj old’s Expedition in 1875, I have had a few 
specimens for examination, collected partly in the Strait 
of Matotshkin Scharr, partly at Cape Grebeni; depth 
2 — 14 fathoms. 
Distribution. The species extends as far as Green- 
land (Kroyer), the east coast of North America (Wilson), 
Barents Sea (Hoek), and the Kara Sea (Hansen). As 
to the statements of its occurrence farther south (in the 
North Sea and off the coasts of England), I am inclined 
to think they must arise from confounding the animal with 
other closely allied forms.

Specific Characters. Body exceedingly slender, with 
widely separated, elongated lateral processes. Cephalic seg- 
ment longer than the 3 following segments taken together, with 
the neck exceedingly slim and elongate, frontal part but 
slightly expanded. Oculiferous tubercle remarkably protube- 
rant, extremity drawn out as a conical point. Proboscis well 
developed, somewhat shorter than the cephalic segment. Che- 
lifori less powerful than in the preceding species; hand hardly 
as long as scape, a little" expanded towards the extremity; 
fingers longer and more curvate than in N. grossipes, 
almost the length of the palm. Palpi very slender. 2nd 
and 3rd joints equal in length, last joint only inconsiderably 
longer than the penultimate one. False legs in male almost 
twice as long as the body, 4th joint a trifle longer than 5th.
