ligesom Saxlemmerne tæt haarede, navnlig i det ydre Parti. 

 Af Leddene er 2det størst. De 2 ydre Led er begge 

 yderst smaa og omtrent af ens Længde, det sidste af af- 

 rundet oval Form. 



De falske Fødder (Fig. i e) er neppe længere end 

 Legemet og har 4de og 5te Led omtrent af ens Udseende 

 og Længde, hvorved er at mærke, at det undersøgte Exem- 

 plar er en Hun. Randtornerne er forholdsvis smaa og 

 stærkt krummede, med meget smaa Sidedtænder. Paa sidste 

 Led (Fig. 1 f) er der 8 saadanne Torner, successivt tilta- 

 gende i Længde mod Spidsen. Endekloen (ibid.) er næsten 

 lige og har 7 smaa Sidetænder. 



Gangfodderne (se Fig. 1) er ualmindelig robuste, 

 QOget sammentrykte og overalt tæt laadne af korte, ens- 

 formigt udviklede Haar. De er neppe 3 Gange længere 

 end Legemet og kun lidet afsmalnende mod Enden. Dog 

 er Laarleddet betydelig bredere end de øvrige. 2det Læg- 

 led er næsten overalt af ens Bredde og omtrent 2 1 /, Gang 

 længere end det terminale Afsnit. Tarsalleddet (se Fig. 

 1 g) er meget kort, neppe længere end bredt, og danner 

 indad en afrundet, med fine Torner besat Lap. Fodleddet 

 er næsten 3 Gange saa langt, noget opsvulmet i sit basale 

 Parti og her i Inderkanten bevæbnet med en Rad af circa 

 8, udåd i Længde tiltagende Torner. Endekloen er for- 

 holdsvis kort, neppe mere end halvt saa lang som Fod- 

 leddet, men særdeles kraftig og stærkt krummet. Bikløerne 

 er vel udviklede, omtrent halvt saa lange som Endekloen. 



Farven var paa det undersøgte Exemplar ensformig 

 graahvid, halvt gjennemsigtig. 



Forekomst. Det ovenfor beskrevne Exemplar toges 

 under Nordhavs-Expeditionens sidste Togt i Saltstrommen, 

 ved Indløbet til Saltenfjord, paa et Dyb af 30—90 Favne 

 mellem Hydroider. Paa andre Steder af vor Kyst har jeg 

 ikke truffet den. 



Udbredning. Arten er udbredt til Island, hvorfra 

 saavel Kriiyers Typeexemplar som det nylig af Dr. Hansen 

 omtalte Individ var. Pan andre Localiteter er den hidtil 

 ikke med Sikkerhed observeret. Thi Angivelserne herom 

 beror ganske sikkert paa en Forvexling med følgende Art.

and, like the chelifori. densely hairy, particularly in the 

 outer part. Of the joints, the 2nd is the largest. The 2 

 outer joints are both very small and about equal in length; 

 the terminal one having a rounded oval form. 



The false legs (fig. 1 e) are hardiy longer than the 

 body, and have the 4th aud 5th joints about uniform 

 in length and appearance ; ljut it is to be noted that the 

 specimen examined was a female. The marginal spines 

 are comparatively small and strongly eurved, with verv 

 minute lateral teeth. On the last joint (fig. 1 f) 8 of 

 these spines occur, increasing successively in length towards 

 the point. The terminal claw (ibid.) is well-nigh straight 

 and lias 7 small lateral teeth. 



The ambulatory legs (see fig. 1) are uncommonly 

 robust, somewhat compressed, and everywhere densely hispid 

 with short, uniformly developed hairs. They are hardiy 3 

 times longer than the body, and taper hut little towards 

 the extremity. The femoral joint, however, is considerably 

 broader than the others. The 2nd tibial joint is alniost 

 uniform in breadth throughout, and about two and a half 

 times as long as the terminal section. The tarsal joint (see 

 fig. 1 g) is very short, scarcely longer than it is broad, and 

 forms inwards a rounded lobe beset with delicate spines. 

 The propodal joint is almost 3 times as long, a little 

 swollen in its basal part aud armed there, on the inner 

 edge, with a series of about 8 spines increasing in length 

 outwards. The terminal claw is comparatively short, 

 scarcely more than half the length of the propodal joint. 

 but exceedingly powerful and strongly eurved. The aux- 

 iliary claws are well developed, about half as long as the 

 terminal elaw. 



In the specimen examined the colour was a uniform 

 greyish white, semi-translucent. 



Occurrenee. The specimen described above was tåken 

 on the North-Atlantic Expedition's last cruise in Saltstrom- 

 men, at the mouth of the Saltenfjord. at a depth of 80 — 90 

 fathoms. among Hydroids. In other localities of the Nor- 

 wegian coast I have not met with the animal. 



Distribution. The range of this species extends to 

 Iceland, whence both Kroyers typical specimen and the 

 individual lately spoken of by Dr. Hansen were obtained. 

 Elsewhere it has not as yet been observed with certainty, 

 as all statements to that effeet assuredly rest on its being 

 confounded with the following species.
