BemEerkninger. N;erv;erende Art udmierker sig 
navnlig ved den ringe Stsrrelse af Snabelen, hvad der liar 
givet Anledning til Artsbenrevnelseu. Ogsaa i de ovrige 
anatomiske Detailler er den, som af ovenstaaende Diagnose 
vil sees, vel adskilt fra de i det foregaaende omtalte Arter. 
Ved npiere at conferere med Dr. Hansens Arbeide over 
Kara II a vets Pycuogonider, ser jeg, at den af ham under 
Benaevnelsen N. longitarse beskrevne Form er denne og 
ikke Krqyers Art. 
Beskrivelse. Legemets Laengde lios det storste af 
de 2 foreliggende Exemplarer, der synes at vsere en ung 
Hun, er 5’"”', med en Spandvidde af 46”"". Dr. Hansen 
opgiver Lamgden til 5,50'"’". 
Legemets Form er (se PI. VII, Fig. 1) meget spinkel 
og Lemmerne tynde og forlsengede. Kroppen (Fig. 1 a, 
1 b) er af smal cylindrisk Form, med Sidefortsatserne 
lange og tynde saint skilte ved brede.Mellemrum. Hoved- 
segmentet er noget lmngere end de 2 falgende Segmenter 
tilsammen og har Halsen meget smal og forlaenget, hvori- 
mod Pandedelen er temmelig stserkt fortykket i Enden. 
Dieknuden (Fig. 1 c). der er beliggende nsesten 3 
Gauge lmngere fra Pan dor an den end fra Hovedsegmentets 
bagre Rand, er ganske lav, med Enden stumpt tilspidset. 
Lindserne er forholdsvis smaa. 
Snabelen (se Fig. 1 a, 1 b) er ualmindelig kort, 
neppe mere end halvt saa lang som Hovedsegmentet og 
noget skraat nedadrettet. Den er af den ssedvanlige cy- 
lindriske Form og betydelig tvkkere end Hovedsegmentets 
Halsdel. 
Saxlemmerne (ibid.) er forholdsvis temmelig smaa og 
har Haanden (Fig. 1 d) noget kortere end Skaftet samt 
taet besat med korte Haar. Fingrene er meget korte, 
neppe mere end halvt saa lange som Pal men og kun lidet 
krummede; som hos de fleste pvrige Arter danner de med 
Palmen en stump Vinkel. 
Fplerne (Fig. 1 e) har 3die Led lidt kortere end 
2det, og sidste Led ualmindelig stort, omtrent dobbelt saa 
langt som naestsidste; begge disse Led er tmt haarede og 
tilsammen adskilligt lmngere end 3die Led. 
De falske Fodder (see Fig. 1 b) er hos det under- 
sOgte Exemplar neppe laengere end Legemet og har 4de 
og -5te Led af ens Liengde. Randtornerne paa de ydre 
Led (Fig. 1 f) ligner i sin Bygning samme hos N. brevi- 
tarse. men har de basale Tam der noget svagere. 
Gangfodderne (se Fig. 1) er meget spinkle og for- 
lsengede, nsesten 5 Gange laengere end Legemet, og besatte 
med spredte Haar. 2det Hofteled er omtrent dobbelt saa 
laa langt som de 2 ovrige tilsammen. De 3 folgende Led 
tiltager successivt i Lsengde og 2det Laegled er omtrent 
with scattered hairs; tarsal joint linear, propodal joint 
likewise very slender and but little shorter than tarsal 
joint, the inner edge beset with delicate, capillary spines, 
of which 2 or 3 in the middle are somewhat stouter; 
terminal claw a good deal produced, but with relatively 
small auxiliary claws. Length of body 5*™, extent 46”””. 
Bemarks. The present species is distinguished chiefly 
by the small size of the proboscis, a character that has sug- 
gested the specific designation. Also in the other anatomical 
details, it is, as shown by the above diagnosis, well defined 
from all the previously mentioned species. After a closer 
comparison with Dr. Hansen’s work on the Pycnogonidea of 
the Kara Sea, I find the form he describes as N. lonc/itarse. 
Kroyer. to be this, and not Kroyer’s species.

Description. The length of the body in the largest 
of the 2 specimens before ’me, apparently a young female, 
is 5””", the extent 46”””. Dr. Hansen gives [the length 
as 5,50’”"’. 
The body (see PI. VII, fig. 1) is very slender and 
the limbs slim and elongated. The trunk (fig. 1 a, 1 b) 
has a narrow, cylindrical form, with the lateral processes 
long and slender and separated by broad interspaces. The 
cephalic segment is somewhat longer than the 2 succeeding 
segments taken together, with the neck very narrow and 
elongated, whereas the frontal part is pretty much tume- 
ficated at the extremity. 
The oculiferous tubercle (fig. 1 c), located well-nigh 3 
times farther from the frontal margin than from the posterior 
edge of the cephalic segment, is quite low, with the extremity 
obtusely pointed. The lenses are comparatively small. 
The proboscis (see fig. 1 a, 1 b) is uncommonly short, 
hardly more than half as long as the cephalic segment. 
! and is directed somewhat obliquely downwards. It has the 
usual cylindric form and is much thicker than the cervical 
part of the cephalic segment. 
The chelifori (ibid.) are, comparatively, rather small 
and the hand (fig. 1 d) is somewhat shorter than the 
scape, also densely beset with short hairs. The fingers 
are very short, hardly more than half as long as the palm 
and but little curvate; as in most of the other species, 
they form an obtuse angle with the palm. 
The palpi (fig. 1 e) have the 3rd joint a little shorter 
than the 2nd. and the last joint uncommonly large, about 
twice as long as the penultimate one; both these joints are 
densely hairy and, taken together, considerably longer than 
the 3rd one. 
The false legs (see fig. 1 b), in the specimen examined, 
are scarcely longer than the body and have the 4th and 
5th joints equal in length. The marginal spines on the 
outer joints (fig. 1 f) resemble in structure those in 
N. brevitarse. but have the basal teeth somewhat feebler. 
The ambulatory ’legs (see fig. 1) are very slim and 
elongated, well-nigh 5 times longer than the body, and beset 
with scattered hairs. The 2nd coxal joint is about twice 
as long as the 2 others taken together. The 3 following 
joints increase successively in length, and the 2nd tibia!
