Artscharacter. Legemet overordentlig spinkelt, med 
vidt skilte Sidefortsatser. Hovedsegmentet stmrkt forleenget, 
lsengere end de 3 fslgende Segmenter tilsammen, Halsen 
srerdeles lang og smal, Pandedelen jevnt ndvidet mod Enden. 
0ieknuden stumpt tilrundet. Snabelen noget kortere end 
Hovedsegmentet. Saxlemmerne forholdsvis svage, Haanden 
noget kortere end Skaftet, kun lidet opsvulmet, haaret, 
Fingrenc forlamgede, af Palinens Lsengde og stmrkt krum- 
mede i Spidsen. Folerne spinkle, 2det og 3die Led af 
ens Laeugde, nmstsidste Led noget kortere end sidste og 
begge tilsammen laengere end 3die. He falske Fodder hos 
Hannen 1 / i Gang laengere end Legemet, 4de og 5te Led 
af ens Laengde, Endedelen laengere end 5te Led; Rand- 
tornernc forholdsvis smaa og mindre tret saugtakkede end 
hos foregaaendc Art. Gangfodderne overordentlig spinkle, 
mere end 5 Gange laengere end Legemet og besatte med 
korte sprcdteHaar; 2det Lsegled nsesten dobbelt saa langt 
so m Laarleddet og sterdeles smalt. Tarsalleddet forlasnget, 
lineael't ; Fodleddet lidet mere end halvt saa langt, Inder- 
kanten besat med meget smaa Tomer; Endekloen noj >] »e 
mere end halvt saa lang som Fodleddet; Bikloerne meget 
smaa. Farven blegrod. Legemets Lsengde 6 mm ; Spand- 
vidde 62"”". 
Bemserkninger. Naervaerende Art ligner noget i sin 
ydre Habitus den ovenfor beskrevne A. microrkynchum, 
med hvilken Hr. Hansen har forvexlet den, men er let 
kjendelig ved den betydelig staerkere forlsengede Hals, 0ie- 
knudens Form, Saxlemmernes Bygning og Forholdet af de 
2 ydre Fodled. 
Beskrivelso. Legemets Lsengde er omtrent 6 mm , med 
en Spandvidde af 62"”". 
Formen er hos denne Art (se PI. VII, Fig. 3) maaske 
spinklere end hos nogen anden Art af Slaegten, saavel 
hvad Kroppen som Lemmerne angaar. Kroppen (Fig. 3 a, 
3 b) er af den saedvanlige smalt cylindriske Form, dog 
ovenfra sect noget afsmalnede bagfra fortil (se Fig. 3 a). 
Sidefortsatserne er lange og smale, samt skilte ved brede 
Mellemrum; som hos N. mixtum , udgaar de alle fra den 
bagre Hel af de respektive Segmenter. Hovedsegmentet 
er af meget betydelig Storrelse, selv laengere end de 3 
fplgende Segmenter tilsammen, og udmasrket ved den over- 
ordentlig smale og forlsengede Hals. Pandedelen udvides 
jevnt mod Enden og er her mere end dobbelt saa bred 
som Halsen. 
Hieknuden (Fig. 3 c). der paa Grand af Halsens 
Lsengde er mere end 3 Gange Isengere fjernet fra Pande- 
randen end fra Hovedsegmentets bagre Rand, er noget 
opheiet, men, uligt de fleste pvrige Arter, stumpt afrundet 
i Enden. Lindserne er forholdsvis store og beliggende 
omtrent ved Midten af Gieknudens Hoide.

arctica, No. 22. 
Specific Characters. Body remarkably slender, with 
widely separated lateral processes. Cephalic segment very 
much elongated, longer than the 3 succeeding ones taken 
together, neck exceedingly long and slender, frontal part 
evenly expanded towards the extremity. Oculiferous tubercle 
obtusely rounded. Proboscis somewhat shorter than the cep- 
halic segment. Chelifori relatively feeble, hand a trifle shorter 
than the scape, only little swollen, hairy, fingers elongate, 
same length as the palm, and sharply curved at the point. 
Palpi slender, 2nd and 3rd joints equal in length, penultimate 
joint somewhat shorter than the ultimate one and both together 
longer than the 3rd. False legs in male 1 / s as long again as the 
body, 4th and 5th joints equal in length, terminal part longer 
than 5th joint; marginal spines comparatively small and less 
densely serrate than in the preceding species. Ambulatory 
legs remarkably slender, more than 5 times longer than 
the body, and beset with short, scattered hairs; 2nd tibial 
joint well-nigh twice as long as the femoral one and exceed- 
ingly slender; tar-sal joint elongate, linear; propodal joint 
little more than half as long, inner edge beset with minute 
spines; terminal claw scarcely more than half the length 
of the propodal joint; auxiliary claws very small. Colour- 
pale red. Length of body 6 mm , extent 62””". 
Remarks. The present species exhibits, in its outer- 
habitus, some resemblance to the above described N. mic- 
rorhynchum , with which Hr. Hansen has confounded it, but 
it is easily distinguishable by the much more elongated neck, 
the form ol the oculiferous tubercle, the structure of the 
chelifori, and the relative lengths of the 2 outer leg-joints. 
Description. The length of the body is about 6 mm , 
the extent 62”"". 
The body (see PI. VII, fig. 3) is in this animal 
more slender, perhaps, than in any other species of the 
genus, both as regards the trunk and the limbs. The 
trunk (fig. 3 a, 3 b) is of the usual narrow, cylindrical form 
but, viewed from above, diminishes a little from rear to front 
(see fig. 3 a). The lateral processes are long and slender, 
and are separated by wide intervals; as in N. mixtum, 
they all issue from the posterior part of the respective 
segments. The cephalic segment is ol very considerable 
size, longer even than the 3 following segments taken 
together, and is characterised by the remarkably slender 
and elongated neck. The frontal part expands uniformly 
towards the end, and is here more than twice as broad 
as the neck. 
The oculiferous tubercle (fig. 3 c), which, owing to 
the length of the neck, lies more than 3 times farther 
from the frontal margin than from the posterior edge of 
the cephalic segment, is somewhat elevated but, unlike most 
of the other species, is obtusely rounded at the extremity. 
The lenses are comparatively large, and are located about 
midway up the tubercle.
