6 stærke Torner, fæstede til ligemange særskilte Afsatser. 

 Endekloen er aoget mere end halvt saa lang som Podleddet 

 og temmelig stærk. Bikløerne er vel udviklede, dog adskil- 

 ligt kortere end hos de 2 foregaaende Arter. 



De ydre Ægmasser (se Fig. 3 e) er af uregelmæssig 

 kugledannet Form og fæstede omkring 4de Led af de fal- 

 ske Fodder. De talrige Æg er omgivne af en fælles tynd 

 membranøs Kapsel. 



Forekomst. Det ovenfor beskrevne Exemplar blev 

 tåget under Nordenskjølds Expedition 1876 i Strædet 

 Matotschkin Sharr paa KJ— 15 F. D., Lerbund. 



Udbredning. Arten er forst beskreven af Krøyer 

 fra Grønland. Derimod er den hverken observeret ved 



Norges eller Englands Kyster; thi Angivelserne om dens 

 Forekomst her beror ganske sikkert paa en Forvexling med 

 enten N. gracile eller ganske unge Exemplarer af en eller 

 anden af de øvrige Arter.

Artscharacter. Legemet noget mindre undersætsigt 

 end hos foregaaende Art. med temmelig lange, vel skilte 

 Sidefortsatser. Hovedsegmentet noget længere end de 2 

 følgende Segmenter tilsammen, Halsen vel begrændset og 

 smalere end Snabelen, Pandedelen temmelig stærkt fortyk- 

 ket. Øieknuden forholdsvis lav, stumpt tilspidset i Enden. 

 Snabelen kortere end Hovedsegmentet. Saxlemmerne af 

 middelmaadig Størrelse, Haanden noget kortere end Skaftet, 

 aflang oval, Fingrene omtrent af Palmens Længde. Fø- 

 lerne med 2det og 3die Led af ens Længde, sidste Led 

 noget hengere end næstsidste. De falske Fodder hos Han- 

 nen længere end Legemet, 4de Led kortere end 5te, Ende- 

 delen omtrent af dette sidste Leds Længde, Randtornerne 

 bredl lancetformige, med et Par stærke Tænder nærmere 

 Basis og det ydre Parti fint og regelmæssigt saugtakket. 

 Gangfødderne neppe 3 Gange længere end Legemet og be- 

 satte med temmelig lange, men spredte Haar ; Tarsalleddet 

 forlænget, lineært; Fodleddet lidt kortere, med omtrent 9 

 stærke Torner i Inderkanten; Endekloen noget mere end 

 halvt saa lang som Fodleddet. meget kraftig; Bikløerne 

 vel udviklede. af Endekloens halve Længde. Legemets 

 Længde 4""" ; Spandvidde 34""". 



than in N. gracile, and has on the inner edge 6 strong 

 spines, eaeh aftixed to its separate ledge. The terminal 

 claw is a little more than half as long as the propodal joint 

 and rather powerful. The auxiliary claws are well devel- 

 oped, though considerably shorter than in the 2 preceding 

 species. 



The outer egg-masses (see fig. 3 e), aftixed round the 

 4th joint of the false legs, have an irregular globular 

 form. The numerous ova are enclosed in common, in a 

 thin membranous capsule. 



Occurrence. The specimen described above was 

 tåken on Nordenskjøld's Expedition. 1876, in the Strait 

 of Matotschkin Sharr at a depth of 10 — 15 fathoms; elay 

 bottom. 



Distribution. This species was first described by 

 Krøyer, from Greenland. It has not been observed, how- 

 ever, either on the coasts of Norway or England, as all 

 statements of its occurrence there have unquestionably 

 arisen from confounding the animal with either .V gracile 

 or quite young examples of some one or other of the 

 known species.

arctica, No. 17. 



Speciflc Character. Body somewhat less thiekset than 

 in the preceding species, with rather long, well separated 

 lateral processes. Cephalic segment somewhat longer than 

 the 2 succeeding segments tåken together, neck well marked 

 ofl' and more slender than proboscis, frontal part very 

 considerably tumified. Oculiferous tubercle eomparatively 

 low, obtusely pointed at the extremity. Proboscis shorter 

 than cephalic segment. Chelifori of moderate size ; hand 

 a trifle shorter than scape, oblongo-oval ; fingers about the 

 length of palm. Palpi with 2nd and 3rd joints equal in 

 length, last joint somewhat longer than penultimate one. 

 False legs in male longer than body ; 4th joint shorter than 

 5th; terminal part about the length of that (oth) joint, mar- 

 ginal spines broadly lanceolate, with a pair of strong teeth 

 nearer the base. and the outer division finely and regularly 

 serrate. Ambulatory legs hardly 3 times longer than body 

 and beset with rather long, but scattered hairs; tarsal joint 

 prolonged, linear; propodal joint a trifle shorter. with about '.> 

 strong spines on the inner edge; terminal claw somewhat 

 more than half as long as the propodal joint, very powerful ; 

 auxiliary claws well developed, half the length of the 

 terminal claw. Length of body 4'/ , extent 34""".
