De ydre Ægmasser forholder sig omtrent som hos
N. grossipes.
Farven hos det levende Dyr er hvidgul med brede,
vakkert orangefarvede Tværbaand over Legemet og
Lemmerne.
Forekomst. Nærværende Art er meget almindelig
langs vor hele Kyst paa 10—50 —100 F. D. Under
Nordhavs-Expeditionen blev Exemplarer tague i
Saltstrømmen samt paa følgende Hav-Stationer: Ståt. 31, 223, 273.
290, den lste beliggende udenfor vor Vestkyst, den 2den
Syd af .Tan Mayen, de 2 sidste Nord af Finmarken;
Dybden fra 70—417 F. Ogsaa fra det kariske Hav har jeg
havt nogle faa Exemplarer til Undersøgelse, indsamlede
under Nordenskjølds Expedition 1875.
Udbredning. Angaaende Artens øvrige Udbredning
er det vanskeligt at afgjøre noget med fuld Sikkerhed, da
senere Forskere ialmindelighed ikke har villet anerkjende
den som saadan. Den synes imidlertid ifølge Dr. Hansens
Meddelelse at forekomme ved Danmark (Hellebæk),
ligesom 2 Exemplarer, ..nærmest svarende til Formen mixtum
Kr.", af samme Forfatter anføres som tagne under Dijmphna’s
Expedition ved Vestkysten af Novaja Semlja. Af Hodge
angives den at forekomme ved England (Kysten af Durham),
og Buchholz nævner Arten fra Østkysten af Grønland og
fra Spitsbergen. De af Hoek fra Challenger Expeditionen
omtalte Exemplarer blev tagne ved Østkysten af
Nord-Amerika (Syd af Halifax), paa 83 F. D. Arten synes
herefter at have en særdeles vid geographisk Udbredning,
skjøndt den nærmest er at betragte som en arktisk Fonn.

Artscharacter. Legemet af spinkel Form, med vidt
adskilte Sidefortsatser. Hovedsegmentet noget længere
end de 2 følgende Segmenter tilsammen. Halsen sinai og
forlænget, Pandedelen temmelig fortykket i Enden.
Øie-knuden meget lav, stumpt tilspidset i Enden. Snabelen
forholdsvis liden, neppe mere end halvt saa lang som
Hovedsegmentet. Saxlemmerue temmelig korte. Haanden
neppe saa lang som Skaftet, tæt haaret; Fingrene meget
korte, neppe mere end halvt saa lange som Palmen.
Følerne med 3die Led noget kortere end 2det, sidste Led
dobbelt saa langt som næstsidste og begge tilsammen
længere end 3die Led. De falske Fødder af middelmaadig
Længde, Randtornerne omtrent som hos N. brevitarse.
Gangfødderne tynde og forlængede, næsten 5 Gange, længere
The outer egg-masses are about as in N. grossipes.
The colour in the living animal is a whitish yellow,
with broad transversal bands of a beautiful orange hue on
the body and limbs.
Occurrence. The present species is very common
along the whole coast of Norway, at a depth of 10—50 —
100 fathoms. On the North Atlantic Expedition specimens
were taken in the Saltström and at the following
ocean-stations: Ståt. 31, 223, 273, 290, the first lying off the
AVest Coast of Norway, the 2nd South ol Jan Mayen,
the 2 last North of Finmark; depth from 70 to 417
fathoms. Also from the Kara Sea I have had a few
specimens for examination, collected on Nordenskjold’s
Expedition in 1875.
Distribution. As to the further distribution of the
species, it is difficult to say anything with certainty, later
naturalists having in general not been disposed to recognize its
claim to specific distinction. Meanwhile it would seem,
according to Dr. Hansen’s statement, to occur on the Coast of
Denmark (Hellebæk), while, also, 2 specimens, „approximating
closest the form mixtum Kr.", are recorded by the same
author as taken .on Dijmphna’s Expedition, on the West
Coast of Novaja Semlja. By Hodge it is said to occur
on the English Coast (that of Durham), and Buchholz
records the species from the East Coast of Greenland and
from Spitzbergen. The specimens mentioned by Hoek
from the Challenger Expedition were taken on the East
Coast of North America (South of Halifax), at a depth of
83 fathoms. The species would seem from these data to
have an exceedingly wide geographical distribution, though
strictly it must be regarded as an Arctic fonn.

Specific Characters. Body slender, with widely
separated lateral processes. Cephalic segment somewhat longer
than the 2 succeeding segments taken together, neck slender
and elongated, frontal part tumeficated at the extremity.
Oculiferous tubercle verv low, obtusely pointed at the end.
Proboscis comparatively small, scarcely more than half as
long as the cephalic segment. Chelifori rather short, hand
hardly as long a$ scape, densely hirsute; Angel’s very short,
hardly more than half as long as palm. Palpi with the 3rd
joint somewhat shorter than the 2nd, last joint twice as long
as the penultimate one. and both taken together longer than
the 3rd joint. False legs of moderate length, marginal
spines about as in N. brei’itarse. Ambulatory legs slim and
elongated, well-nigh 5 times longer than the body, and beset
