en sylforraig Spids. Derimod er Bikloerne forholdsvis meget 

 mindre end hos hin Art, neppe l / 10 saa l an 9-' sora Ende- 

 kloen. 



De ydre Ægmasser (se Fig. 3 a) forholder sig omtrent 

 som hos foregaaende Art. Æggené er yderst smaa og 

 talrige. 



Forekomst. Ved vore Kyster synes denne Art kun 

 at være indskrænket til den arktiske Region; jeg har saa- 

 ledes tåget den ikke sjelden i Varangerfjord ved Vadsø 

 paa 60 — lm» F. D. Under Nordhavs-Expeditionen erholdtes 

 talrige Exemplarer paa forskjellige Punkter, saaledes ved 

 Jan Maven, i Adventbay paa Spitsbergen og i Havet uden- 

 for Spitsbergens Nordvestkyst (Stat. 362, 363); Dybden 

 fra 70 til 459 Favne Desuden har jeg havt til Under- 

 sogelse flere vel udprægede Exemplarer fra det kariske 

 Hav. indsamlede under Nordenskjølds Expedition 1875; 

 Dybden 10—80 Favne. 



Udbredning. Arten synes at have en vid Udbred- 

 ning i de arktiske Have. Den er saaledes observeret ved 

 Frants Josephs Land (Heller), i Barents Soen (Hoek), det 

 kariske Hav (Hansen), Grinnels Land (Miers) og, som jeg 

 formoder, ogsaa ved Østkysten af Nordamerika (Wilson).

 Artscharacter. Temmelig lig de 2 foregaaende Arter, 

 men noget spinklere og med Sidefortsatserne videre skilte. 

 Hovedsegmentet længere end de 3 følgende Segmenter til- 

 sammen. Halsen tynd, Pandedelen stærkt udvidet. Øie- 

 knuden særdeles lav, afrundet. Snabelen kortere end Hoved- 

 segmentet, smalt cylindrisk. Saxlemmerne meget stærkt 

 forlængede og smækre; Skaftet krummet i Enden; Haanden 

 neppe længere end Skaftet, stærkt buet og smal, Fingrene 

 af Palmens Længde, Spidsen af den bevægelige Finger 

 knudeformig fortykket . af den ubevægelige hageformigt 

 indkrummet, Tænderne i Inderkanten af Fingrene, navnlig 

 paa den ubevægelige. af meget ulige Størrelse. Følerne 

 særdeles tynde og forlængede. 2det Led betydelig længere 

 end 3die, de 2 sidste Led af ens Længde og tilsammen 

 neppe længere end 3die. De falske Fødder hos Hannen 

 omtrent af Legemets Længde. meget tynde, 5te Led længst 

 og længere end Endedelen, Randtornerne smalt lancetfor- 

 mige og grovt saugtakkede i Kanterne. Gangfodderne 



almost as long as the propodal joint, and very narrow, 

 running out to an awl-shaped point. The auxiliary claws 

 are, on the contrary, relatively much smaller than in that 

 species, hardly one-tenth as long as the terminal claw. 



The outer egg-masses (see fig. 3 a) have much the 

 same character as in the preceding species. The ova are 

 exceedingly small and numerous. 



Occurrence. On the eoasts of Norway this species 

 seems to be restricted to the Arctic region. I have, thus, 

 not infrequently tåken the animal in the Varangerfjord 

 near Vadso. at a depth of from 60 to 100 fathoms. On 

 the North-Atlantic Expedition numerous specimens were 

 collected in divers localities; for instance, off Jan Mayen, 

 in Advent Bay. Spitzbergen, and in the ocean off the north- 

 west coast of Spitzbergen (Stats. 362, 363); depth from 

 70 to 459 fathoms. I have, besides, had sent me for ex- 

 amination, several well-marked specimens from the Kara 

 Sea, tåken on NordenskjokFs Expedition in 1875; depth 

 from 10 to 80 fathoms. 



Distribution. The species seems to be widely dis- 

 tributed throughout the Arctic Seas. It has been met 

 with off Frantz Joscph's Land (Heller), in the Barents Sea 

 (Hoek). the Kara Sea (Hansen), off Grinnel's Land (Miers). 

 and. as I suppose. also on the east coast of North-America 

 (Wilson).

Speeifle Characters. Rather closely resembling the 

 2 preceding species. but somewhat slenderer, and with the 

 lateral processes farther apart. Cephalic segment longer 

 than the 3 following segments tåken together. neck thin. 

 frontal part much expanded. Oculiferous tubercle exceed- 

 ingly low. rounded. Proboscis shorter than the cephalic 

 segment, narrow cvlindrical. Chelifori verv much elongated 

 and slender; scape curved at the extremity; hand hardly longer 

 than the scape, exceedingly arcuate and narrow. fingers same 

 length as palm, point of the mobile finger incrassated in 

 tuberculiform. and of the immobile one unguiformly incurvate, 

 teeth on inner edge of the fingers, especiallv on the immobile 

 one, very unequal in size. Palpi exceedingly thin and elongated. 

 2nd joint considerably longer than the 3rd. the 2 last joints 

 equal in length and. tåken together. hardly longer than the 

 3rd. False legs in male about same length as the body. very 

 thin. oth joint longest and longer than the terminal part, 

 marginal spines slender lanceolate and coarsely serrated
