De ydre Ægmasser forholder sig omtrent som hus 

 N. grossipes. 



Farven hos det levende Dyr er hvidgul med brede, 

 vakkert orangefarvede Tværbaand over Legemet og Lera- 

 merne. 



Forekomst. Nærværende Art er meget almindelig 

 langs vor hele Kyst paa 10—50—100 F. D Under 

 Nordhavs-Expeditionen blev Exemplarer tagne i Saltstrøm- 

 men samt paa følgende Hav-Stationer : Stat. 31, 223, 273, 

 290, den Iste beliggende udenfor vor Vestkyst, den 2den 

 Syd af Jan Mayen, de 2 sidste Nord af Finmarken; Dyb- 

 den fra 70 — 417 F. Ogsaa fra det kariske Hav har jeg 

 havt nogle faa Exemplarer til Undersøgelse, indsamlede 

 under Nordenskjølds Expedition 1875. 



Udbredning. Angaaende Artens øvrige Udbredning 

 er det vanskeligt at afgjøre noget med fuld Sikkerhed, da 

 sanere Finskere ialmindeliglied ikke har villet anerkjende 

 den som saadan. Den synes imidlertid ifølge Dr. Hansens 

 Meddelelse at forekomme ved Danmark (Hellebæk), lige- 

 som 2 Exemplarer, ..nærmest svarende til Formen mixtum 

 Kr.", af samme Forfatter anføres som tagne under Dijmphna's 

 Expedition ved Vestkysten af Novaja Semlja. Af Hodge 

 angives den at forekomme ved England (Kysten af Durham), 

 og Buchholz nævner Arten fra Østkysten af Grønland og 

 fra Spitsbergen. De af Hoek fra Ohallenger Expeditionen 

 omtalte Exemplarer blev tagne ved Østkysten af Nord- 

 Amerika (Syd af Halifax i. paa 83 F. D. Arten synes 

 herefter at have en særdeles vid geographisk Udbredning, 

 skjondt den nærmest er at betragte som en arktisk Form.

Artscharacter. Legemet af spinkel Form. med vidt 

 adskilte Sidefortsatser. Hovedsegmentet noget hengere 

 end de 2 følgende Segmenter tilsammen, Halsen smal og 

 forlænget, Pandedelen temmelig fortykket i Enden. Øie- 

 knuden meget lav, stumpt tilspidset i Enden. Snabelen 

 forholdsvis liden, neppe niere end halvt saa lang si mi 

 Hovedsegmentet. Saxlemmerne temmelig korte. Haanden 

 neppe saa lang som Skaftet, tæt haaret; Fingrene meget 

 korte, neppe mere end halvt saa lange som Palmen. 

 Følerne med 3die Led noget kortere end 2det, sidste Led 

 dobbelt saa langt som næstsidste og begge tilsammen 

 længere end 3die Led. De falske Fødder af middelmaadig 

 Længde, Randtornerne omtrent som hos N. brevitarse. 

 Gangfodderne tynde og forlrengede, næsten 5 Gange hengere 



The outer egg-masses are about as in N. urossipes. 



The colour in the living animal is a whitish yellow, 

 with broad transversal bands of a beautiful orange hue on 

 the body and limbs. 



Oecurrenee. The present species is very common 

 along the vvhole coast ul' Norway, at a depth of l<i — 50— 

 100 fathoms. On the North Atlantic Expedition specimens 



tåken in the Saltstrom and at the following ocean- 

 stations: Stat. 31, 223, l'7;J, 290, the Brsl Lying off the 

 West Coast of Norway, the 2nd South oi Jan Mayen, 

 the 2 last North of Finmark; depth from 70 to 417 

 fathoms. Also from the Kara Sea I have had a few 

 specimens tor examination, collected on Nordenskjøld's 

 Expedition in 1875. 



Distribution. As to the turther distribution of the 

 species, it is difficult to say anything with eertainty, later natur- 

 alists having in general not been disposed to recognize its 

 claim tu specific distinction. Meanwhile it would seem, ac- 

 cording to Dr. Hansen 's atatement, to occur on the Coasl of 

 Denmark (Hellebæk), while, also. 2 specimens. „approximating 

 closest the form mixtum Kr.", are recorded by the same 

 author as tåken on Dijniphna's Expedition. on the West 

 Coast of Novaja Semlja. By Hodge it is said to occur 

 on the English Coast (tbat of Durham), and Buchholz 

 records the species from the East Coast of Greenland and 

 from Spitzbergen. The specimens mentioned by Hoek 

 from the Challenger Expedition were tåken on the East 

 Coast of North America (South of Halifax), at a depth of 

 83 fathoms. The species would seem from these data to 

 have an exceedingly wide geographical distribution, though 

 strictlv it must be regarded as an Arctic form.

 Specific Characters. Body slender. with widely sep- 

 arat. d lateral processes. Cephalic segment somewhat longer 

 than the 2 succeeding segments tåken together, neck slender 

 and elongated, frontal part tumeficated at the extremity. 

 Oculiferous tubercle very low, obtusely pointed at the end. 

 Proboscis comparatively small, scareely more than half as 

 long as the cephalic segment. Chelifori rat her short, hand 

 hardly as long a§ scape, densely hirsute; fingers very short, 

 harilly more than half as long as palm. Palpi with the ord 

 joint somewhat shorter than the 2nd, last joint twice as long 

 as the penultimate one. and both tåken together longer than 

 the 3rd joint. False legs of moderate length, marginal 

 spines about as in N. brevitarse. Ambulatory legs slim and 

 elongated, well-nigh 5 times longer than the body, and beset
