stærkt forlænget, næsten dobbelt saa langt som Laarleddet 

 og omtrent 1 4 længere end det terminale Afsnit. Tarsal- 

 leddet (se Fig. 2 i) er af lineær Form og betydelig hengere 

 end Fodleddet, der er kjendelig smalere og i Inderkanten 

 besat med en Rad af meget smaa Torner, mellen) hvilke 

 der tindes fine Haar (se Fig. 2 k). Endekloen er ualmin- 

 delig kort. neppe halvt saa lang som Fodleddet, men meget 

 stærk, sammentrykt og endende i en skarp Spids. Bikløerne 

 er ai' middelmaadig Størrelse, næsten 1 / 3 saa lange som 

 Endekloen. 



De ydre Ægmasser (se Fig. 2") er temmelig store, 

 kugleformige, og indeholder talrige yderst smaa Æg. Ofte 

 er de tilstede i dobbelt Antal paa enhver af de ialske Kodder. 



Farven er i levende Tilstand mere eller mindre intenst 

 gulrød, navnlig mod Enden af Leddene paa Pødderne. 



Forekomst. Dette er uden Sammenligning den ved 

 vor Syd- og Vestkyst almindeligste Pycnogonide og forekom- 

 mer ofte i store Mængder paa maadeligt Dyb, fra 10 til 

 50 Favne, Det nordligste, jeg har truffet den er ved 

 Lofoten. Ved Finmarken synes den derimod at erstattes 

 af følgende Art. 



Udb redning. Foruden ved Norge er Arten kun med 

 Sikkerhed observeret ved England (Goodsir) og Østkysten 

 af Nordamerika (Wilson); thi Angivelserne af dens Fore- 

 komst i de arktiske Have beror ganske sikkert paa en 

 Forvexling med følgende Art. At dømme efter dens Fore- 

 komst ved vore Kyster, synes den a.t være en mere sydlig 

 (boreal) Form.

 Artscharacter. Ydre Habitus meget lig samme hos 

 foregaående Art. Hovedsegmentet betydelig længere end 

 de 3 følgende Segmenter tilsammen. Pandedelen endnu 

 bredere end hos N. Strømii. Øieknuden lav, stumpt af- 

 kuttet i Enden. Snabelen af Hovedsegmentets Længde, 

 QOget afsmalnende. Saxlemmerne forholdsvis større og 

 kraftigere end hos foregaående Art, Haanden betydelig 

 længere end Skaftet, stærkt buet, Fingrene hengere end 

 Palmen. Spidsen af den bevægelige næsten ret, af den 



joint is appreciably longer than the femoral one and the 

 2nd joint is remarkably elongated, well-riigh 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). The 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 eontain numerous, exceedingly small ova. 

 They often occur in double numbers on each of the false legs. 



The colour in the living state, is a more or less 

 intense yellowish-red, partieularly 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 1 to 50 fathoms. The farthest north that I have 

 tåken 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 eertainty been 

 observed; as the statements of its occurrence in the Arctic 

 seas rest quite assuredly on a confusion of the animal with 

 the following species. To judge from its occurrence off the 

 coasts of this country, it would seem to be a more southern 

 (boreal) form.

Speciflc Characters. Outer habitus much the same 

 as in the preceding species. Cephalic segment considerably 

 longer than the 3 following segments tåken together. frontal 

 part still broader than in V. Stromii. 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
