bugtede samt ender i en fint udtrukken Spids (Fig. 3 g). 

 Endepartiet er betydelig længere i'iid 5te Led og har Iste 

 Lcd størst samt besat med lignende Børster som de paa 

 foregaaende Led. De paa de -1 ydre Led fæstede Rand- 

 torner (se Fig. 3 i) er forholdsvis smaa og ganske simple, 

 ilden Spor af Saugtakker, og heller ikke Endekloen (se 

 Fig. 3 h) viser nogen Antydning til de sædvanlige Side- 

 tænder. 



Gangfødderne (se Fig. 3) er vistnok af betydelig 

 Længde, idet de er over 3 Gange hengere end Legemet, 

 men dog idethele temmelig robuste og kun lidet afsmal- 

 nende mod Enden. De ser for det blotte Øie ganske 

 glatte ad. Ved nøiere Undersøgelse med en stærk Lupe 

 viser de sig imidlertid i sin hele Længde tæt besatte med 

 særdeles korte, men stærke, næsten pigformige Haar, der 

 giver dem en noget ru Overflade. De 3 Hofteled er 

 forholdsvis korte og næsten af ens Længde, eller det 2det 

 kun ubetydelig længere end de øvrige. Laarleddet er om- 

 trent dobbelt saa langt som Hoftepartiet og udmærker sig 

 ikke hos Hunnen ved nogen paafaldende Opsvulmning, saa- 

 ledes som hos Arterne af foregaaende Slægt, skjøndt det 

 er noget tykkere end hos Hannen. 2det Lægled afsmalnes 

 ganske svagt mod Enden og er omtrent 2 1 / s Gang længere 

 end det terminale Afsnit. Dette sidste (se Fig. 3 k) er 

 kjendelig smalere og har Tarsalleddet af simpel cylindrisk 

 Form. Fodleddet er 1 j- J Gang til saa langt og betydelig 

 smalere end Tarsalleddet, af lineær Form og mangler tyde- 

 lige Torner i Inderkanten. hvorimod det ligesom Tarsal- 

 leddet er rundt om besat med samme Slags smaa pigfor- 

 mige Haar som paa den øvrige Del af Foden. Ende- 

 kloen er betydelig kortere end Fodleddet, eller omtrent af 

 Tarsalleddets Længde, temmelig smal og jevnt krummet, 

 gaaende ud i en sylskarp Spids. Bikløerne synes ved 

 forste Øiekast ganske at mangle. Føist ved stærk For- 

 størrelse (Fig. 3 1) bemærkes paa deres Plads 2 yderst 

 smaa og fine Pigge som et Rudiment af samme. 



De ydre Ægmasser (se Fig. 3 a) er af kugledannet 

 Form og indeholder talrige Æg af middels Størrelse. 

 Oftere træffer man disse Masser sammensatte af de ud- 

 klækkede Larver i alle Udviklingsstadier; ja selv længe 

 eiter at Ungerne har tilbagelagt Larvestadiet og opnaaet 

 en meget anselig Størrelse, træffer man dem fastklamrede 

 til Hannens Legeme. Saavel hos Han som Hun er Fod- 

 derne og tildels ogsaa Kroppen ofte besat med forskjellige 

 pseudoparasitiske Organismer, især Polyzoer. 



Forekomst. Af denne characteristiske Form blev 

 talrige Exemplarer indsamlede under Nordhavs-Expedi- 

 tionens samtlige 3 Togter. Vi har noteret den fra 5 for- 

 skjellige Stationer, tildels beliggende i betydelig Afstand 

 fra hverandre. En af disse (Stat. 18) ligger i Havet 

 mellem Færøerne og Norge; en anden (Stat. 48) Øst af 

 Island; en 3die (Stat. 192) Nord af Vesteraalen, de 2 øvrige 

 (Stat. 362 og 363) NV af Spitsbergen; Dybden fra 260 



and terminate in a finely drawn out point (fig. 3 g). The 

 terminal division is considerably longer than the oth joint. 

 and has the Ist joint the largest, and also beset with 

 bristles similar to those on the preceding joint. The 

 marginal spines (see fig. 3 i), secured to the 4 outer joints, 

 are relatively small and quite plain. without trace of 

 secondary teeth; neither does the terminal claw (see fig. 

 3 h) show any indication of the usual lateral teeth 



The ambulatory legs (see fig. 3) are, indeed. of con- 

 siderable length, as they are more than 3 times longer 

 than the body but. vet. upon the whole, are robust, and 

 only diminish slightly towards the extremity. To the 

 naked eve they appear quite smooth. Upon closer ex- 

 amination with a powerful magnifier, they, however, appear 

 closely beset throughout their entire length with particul- 

 arly short hut strong, almost spiniform hairs, which gives 

 them a somewhat rough exterior surface. The 3 eoxal 

 joints are relatively short and almost equal in length. or 

 the 2nd only slightly longer than the others. The femoral 

 joint is about twice as long as the coxal section. and is 

 not distinguished, in the female, by any remarkable tumefi- 

 cation like that in the species of the preceding genus, 

 although it is somewhat thicker than in the male. The 

 2nd tibial joint is quite faintly diminished towards the 

 extremity. and is about 2 1 /,. times longer than the ter- 

 minal division. This last (see fig. 3 k) is appreciably nar- 

 rower, and has the -tarsal joint plain cylindric in form. 

 The propodal joint is 1 / s as long again, and considerably 

 narrower than the tarsal joint, linear in form, and defieient 

 in distinct spines on the inner margin, while, on the other 

 hand, it. like the tarsal joint, is beset roundabout with 

 the same kind of small spiniform hairs as upon the other 

 part of the leg. The terminal claw is considerably shoi - ter 

 than the propodal joint, or about half the length of the 

 tarsal joint, råtner narrow and uniformly curved. terminating 

 in a point sharp as an awl. The auxiliary claws appear 

 at the first glance to be entirely absent. It is only upon 

 powerful magnification that there are observed. in their 

 place. 2 extremely minute and delitate spines as a rudi- 

 ment of them. 



The outer egg-masses (see fig. 3 a) are globular in 

 form and contain numerous ova of medium size. We 

 frequently find those masses composed of the hatched 

 larvæ in all stages of development, indeed. even long after 

 the young have relinquished the larval stage and attained 

 a most respectable size, we find them firmly adherent to 

 the body of the male. Both in the male and the female, 

 the legs, and partly also the body, are often covered with 

 various pseudo-parasitic organisms, especially Polyzoa. 



Oceurrence. Of this characteristic form numerous 

 specimens were collected during all the 3 cruises of the 

 North Atlantic Expedition. We have remarked it at 5 

 different stations, separated. partly. by a considerable dis- 

 tance from each other. One of those (Stat. 18) is situated 

 in the ocean between the Faroe Island and Norway; a 

 second (Stat. 48) east of Iceland; a third (Stat. 192) north 

 of Vesteraalen ; the 2 others (Stat. 362 and 363) north-west
