Fig. 1 <k der navnlig paa den ubevægelige Finger er af 

 meget ulige" Længde, idet større Tiender her temmelig 

 regelmæssigt afvexler med neppe halvt saa store. Begge 

 Fingre udmærker sig forøvrigt i hoi Grad ved den eiendom- 

 melige Maade, hvorpaa de ender. Den ubevægelige Finger 

 gaar nemlig ud i en særdeles stærkt, hageformigt indad- 

 krummet skarp Spids, medens den bevægelige omvendt 

 ender med en stum]) knudeformig Opsvulmning (se Fig. 1 d). 



Følerne (Fig. 1 e) er overordentlig tynde og for- 

 længede, hvorfor de ialmindelighed viser en meget stærk 

 zigzag-formig Krumning. Det indbyrdes Længdeforhold af 

 Leddene skiller sig ogsaa kjendeligt fra samme hos de 2 

 foregaaende Arter. 2det Led er saaledes her betydelig 

 længere end 3die, hvorimod de 2 ydre Led er forholdsvis 

 mindre og smalere, omtrent af ens Størrelse og begge til- 

 sammentagne neppe længere end 3die Led. Som hos de 

 2 foregaaende Arter er disse Lemmer kun besatte med 

 meget korte og spredte Haar. 



De falske Fodder hos Hannen (se Fig. 1 a) er for- 

 holdsvis meget spinkle og lige udstrakte neppe længere end 

 Legemet. Af Leddene er det 5te storst og længere end 

 Endedelen. Randtornerne (Fig. 1 < ) er smalt lancetfor- 

 mige og grovt saugtakkede i Kanterne. 



Gangfødderne (se Fig. 1) er meget spinkle og stærkt 

 afsmalnende mod Enden, samt næsten nøgne. De er hen- 

 imod 5 Gange længere end Legemet og har 2det Lægled 

 forholdsvis endnu stærkere forlænget end hos N. gracilipes 

 og af særdeles smal lineær Form. Det terminale Afsnit 

 er neppe 1 J i saa langt som 2det Lægled og har Fodleddet 

 noget kortere end Tarsalleddet ; begge Led er smalt lineære 

 og i den indre Kant bevæbnede med korte Torner, imellem 

 hvilke staar Grupper af meget finere saadanne. Ende- 

 kloen er betydelig kortere end 'Fodleddet, dog af kjendelig 

 spinklere Form end hos A 7 . Strømit. Bikløerne er for- 

 holdsvis smaa, neppe mere end l / 4 saa lange som selve 

 Kloen. 



De ydre Ægmasser (se Fig. 1 a) er forholdsvis mindre 

 end hos de 2 foregaaende Arter, af kugledannet Form og 

 kun tilstede i et enkelt Par. Derimod er Æggene kjen- 

 delig større end Ims hine Arter. 



Forekomst. Ved vore Kyster har jeg endnu ikke 

 observeret denne Art. Derimod toges den under Nordhavs- 

 Expeditionen i stort Antal paa mange forskjellige Punkter. 

 Den er noteret fra ikke mindre end 11 forskjellige Sta- 

 tioner, nemlig: St. 18, 31, 48, 124, 164, 262, 275, 312, 

 315, 343, 363. Af disse ligger de 3 første i den sydligste 

 Del at det af os undersogte Havstrog, dels nærmere den 

 m irske Kyst, dels nærmere Island (St. 48); de 2 følgende 

 Stationer ligger i Havet udenfor Nordlandskysten og Lofoten ; 

 de øvrige 6 falder alle paa den nordlige Del af det af os 

 bereiste Havstrøg, dels i Østhavet (St. 262, 275), dels i 

 Naboskabet af Beeren Eiland og Spitsbergen; Dybden fra 



appearance. The fingers are about as long as the palm. 

 and both have, on the inner edge. numercus sharply pointed 

 teeth (see fig. 1 d), which. more particularly on the im- 

 mobile finger, are very unequal in length. as, here. largish 

 teeth alternate pretty regularly with others scarcely half 

 their size. Both fingers are prominently distinguished. other- 

 wise, by the peculiar way in which they terminate. The 

 immobile finger runs, thus, out into a very strongly ungui- 

 form incurvate sharp point, while the mobile one terminates, 

 on the contrary. in an obtuse tuberculiform swelling (see 

 fig. 1 d). 



The palpi (fig. 1 e) are remarkably slender and 

 elongated, and exhibit therefore, as a rule, a very prominent 

 zigzag-shaped curvature. The longitudinal relations of the 

 joints hiter se differ, too, appreciably, from those in the 2 

 preceding species. Thus. the 2nd joint is considerably 

 longer than the 3rd, whereas the 2 outer joints are rélatively 

 smaller and more slender. about equal in length. and both 

 tåken together hardly longer than the 3rd joint. As in 

 the 2 preceding species, those limbs are only beset with 

 very short and scattered hairs. 



The false legs in the male (see fig. 1 a) are rélatively 

 very slender, and. when fully extended hardly longer than 

 the body. Of the joints, the 5th is the largest. and 

 longer than the terminal part. The marginal spines (fig. 



I f) are narrow lanceolate, and coarsely serrated on the 

 edges. 



The ambulatory legs (see fig. 1) are very slender, taper 

 rapidly towards the end, and are well-nigh bare. They 

 are nearly 5 times longer than the body, and have the 

 2nd tibial joint, rélatively, still more elongate than in N. gra- 

 cilipes, and particularly narrow linear in form. The terminal 

 section is scarcely one-fourth' as long as the 2nd tibial joint, 

 and has the propodal joint somewhat shorter than the 

 tarsal joint; both joints are narrow linear, and armed 

 on the inner edge with short spines between which are 

 groups of delicate spinules. The terminal claw is con- 

 siderably shorter than the propodal joint, but appreciably 

 slenderer than in N. Stromii. The auxiliary claws are 

 comparatively small, hardly more than one-fourth as long- 

 as the claw itself. 



The outer egg-masses (see fig. 1 a) are rélatively 

 smaller than in the 2 preceding species, are globular in 

 form and present only as a single pair. The ova. on the 

 contrary, are perceptibly larger than in those species. 



Occurrenee. I have not. as vet, observed this species 

 on the coasts of Norway. The animal was. however. met 

 with on the North-Atlantic Expedition in great abundance 

 at many different places. It is noted from not less than 



II different Stations, viz: Sts. 18, 31, 48, 124. 164,262, 

 275, 312, 315, 343, 363. Of these, the 3 first lie in the 

 southernmost part of the ocean tract investigated by the Ex- 

 pedition, partly not far from the Norwegian coast and partly 

 not far from Iceland (St. 48); the 2 following Stations lie 

 in the seas off the coasts of Nordland and Lofoten; the re- 

 maining 6 are all located in the northern part of the ocean 

 tract explored. 2 in the Barents' Sea (Sts. 262, 275) and
