staerkt forlsenget, naesten clobbelt saa langt som Laarleddet 
og omtrent 1 ji lsengere end det terminale Afenit. Tarsal- 
leddet (se Fig. 2 i) er af linear Form og betydelig lsengere 
end Fodleddet, der er kjendelig smalere og i Inderkanten 
besat med en Rad af meget smaa Torner, mellem bvilke 
der Andes fine Haar (se Fig. 2 k). Endekloen er ualmin- 
delig kort, neppe halvt saa lang som Fodleddet, men meget 
stark, sammentrykt og endende i en skarp Spids. Bikloerne 
er af middelmaadig Storrelse, Hasten 1 /-j saa lange som 
Endekloen. 
De ydre .ZEgmasser (se Fig. 2) er temmelig store, 
kugleformige, og indeholder talrige yderst smaa iEg. Ofte 
er de tilstede i dobbelt Antal paa enhver af de falske Fodder. 
Farven er i lovende Tilstand mere eller mindre intenst 
gulrod, navnlig mod Enden af Leddene paa Fpdderne. 
Forekomst. Dette er nden Sammenligning den ved 
vor Syd- og Yestkyst almindeligste Pycnogonide og forekom- 
mer ofte i store M*ngder paa maadeligt Dyb, fra 10 til 
50 Favne. Det nordligste, jeg har truffet den er ved 
Lofoten. Yed Finraarken synes den derimod at erstattes 
af fplgende Art. 
Udbredning. Foruden ved Norge er Arten lain med 
Sikkerhed observeret ved England (Goodsir) og Gstkysten 
af Nordamerika (Wilson); thi Angivelserue af dens Fore- 
komst i de arktiske Have beror ganske sikkert paa en 
Forvexling med folgende Art. At domino efter dens Fore- 
komst ved vore Kyster, synes den at vsere en mere sydlig 
(boreal) Form.

Arts character. Ydre Habitus meget lig samme lios 
foregaaende Art. Hovedsegmentet betydelig lsengere end 
de 3 folgende Segmenter tilsammen, Pandedelen endnu 
bredere end bos N. Stremi. 0ieknuden lav, stumpt af- 
kuttet i Enden. Snabelen af Hovedsegmentets Lamgde, 
noget afsmalnende, Saxlemmerne forboldsvis storre og 
kraftigere end hos foregaaende Art, Haanden betydelig 
lfengere end Skaftet, stserkt buet, Fingrene lsengere end 
Palmen, Spidsen af den bevsegelige nsesten ret, af den 
joint is appreciably longer than the femoral one and the 
2nd joint is remarkably elongated, well-nigh twice as long 
as the femoral joint and about one-fourth longer than the 
terminal section. The tarsal joint (see fig. 2 i) is linear in 
form and considerably longer than the propodal joint, which 
is appreciably Slenderer and beset on the inner edge with 
a series of very small spines with fine hairs between them 
(see fig. 2 k). Tim terminal claw is uncommonly short, hardly 
half as long as the propodal joint, but very strong, com- 
pressed, and terminating in a sharp point. The auxiliary 
claws are of moderate size, almost one-third longer than 
the terminal claw. 
The outer egg-masses (see fig. 2) are rather large, glob- 
ular in shape, and contain numerous, exceedingly small ova. 
They often occur in double numbers on eacli of the false legs. 
The colour in the living state, is a more or less 
intense yellowish-red, particularly towards the end of the 
joints of the legs. 
Occurrence. This is beyond comparison the Pycnogonid 
most commonly met with on the south and west coasts of 
Norway, and often occurs in great abundance at moderate 
depths, from 10 to 50 fathoms. The farthest north that I have 
taken it is off Lofoten. On the Finmark coast it appears, on 
the other hand, to be replaced by the following species. 
Distribution. Besides off Norway, England (Goodsir) 
and the east coast of North America (Wilson) are the 
only places where the species has with certainty been 
observed; as the statements of its occurrence in the Arctic 
seas rest cpute assuredly on a confusion oi the animal w Lh 
the following species. To judge from its occurrence off the 
coasts of this country, it would seem to be a more southern 
(boreal) form.

Specific Characters. Outer habitus much the same 
as in the preceding species. Cephalic segment considerably 
longer than the 3 following segments taken together, frontal 
part still broader than in N. Strimii. Oculiferous tubercle low, 
obtusely truncated at the extremity. Proboscis same length 
as the cephalic segment, somewhat tapering. Chelifori rela- 
tively larger and more powerful than in the preceding species, 
hand considerably longer than the scape, exceedingly arcuate, 
fingers longer than the palm, the point of the mobile one
