/ 
bugtede samt ender i en fint udtrukken Spids (Fig. 3 g). 
Endepartiet er betydelig lamgere end 5te Led og liar lste 
Led storst samt besat med lignende Burster som de paa 
foregaaende Led. De paa de 4 yd re Led fsestede Rand- 
torner (se Fig. 3 i) er forholdsvis smaa og ganske simple, 
uden Spor af Saugtakker, og heller ikke Endekloen (se 
Fig. 3 h) viser nogen Antydning til de saedvanlige Side- 
tsender. 
Gangfodderne (se Fig. 3) er vistnok af betydelig 
Liengde, idet de er over 3 Gange lsengere end Legemet, 
men dog idethele temmelig robuste og kun lidet afsmal- 
nende mod Enden. De ser for det blotte 0ie ganske 
glatte ud. Yed noiere Undersogelse med en stserk Lupe 
viser de sig iinidlertid i sin hele Lsengde tait besatte med 
sairdeles korte, men staerke, nsesten pigformige Haar, der 
giver dem en noget ru Overflade. De 3 Hofteled er 
forholdsvis korte og nsesten af ens Laengde, eller det 2det 
kun ubetydelig lamgere end de ovrige. Laarleddet er om- 
trent dobbelt saa langt som Hoftepartiet og udmserker sig 
ikke hos Hunnen ved nogen paafaldende Opsvulmning, saa- 
ledes som hos Arterne af foregaaende Slsegt, skjondt det 
er noget tykkere end hos Hannen. 2det Lsegled afsmalnes 
ganske svagt mod Enden og er onitrent 2 1 /-a Gang lamgere 
end det teriuiiiale Afsnit. Dette sidste (se Fig. 3 k) er 
kjendelig smalere og har Tarsalleddet af 'simpel cylindrisk 
Form. Fodleddet er Gang til saa langt og betydelig 
smalere end Tarsalleddet, af lineser Form og mangier tyde- 
lige Torner i Inderkanten. hvorimod det ligesom Tarsal- 
leddet er rundt om besat med samme Slags smaa pigfor- 
mige Haar som paa den pvrige Del af Foden. Ende- 
kloen er betydelig kortere end Fodleddet, eller omtrent af 
Tarsalleddets Lsengde, temmelig smal og jevnt krummet, 
gaaende ud i en sylskarp Spids! Bikloerne synes ved 
fprste 0iekast ganske at mangle. Foist ved stserk For- 
storrelse (Fig. 3 1) bemaerkes paa deres Plads 2 yderst 
smaa og fine Pigge som et Rudiment af samme. 
De ydre iEgmasser (se Fig. 3 a) er af kugledannet 
Form og indeholder talrige iEg af middels StOrrelse. 
Oftere tneffer man disse Masser sammensatte af de ud- 
klsekkede Larver i alle Udviklingsstadier; ja solv kenge 
efter at Ungerne har tilbagelagt Larvestadiet og opnaaet 
en nieget auselig Storrelse, trreffer man dem fastklamrede 
til Hannens Legeme. Saavel hos Han som Hun er Fod- 
derne og tildels ogsaa Kroppen ofte besat med forskjellige 
pseudoparasitiske Organismer, isser Polyzoer. 
Porekomst. 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 Fmroerne og Norge; en anden (Stat. 48) 0st af 
Island; en 3die (Stat. 192) N ord af Vesteraalen, de 2 ovrige 
(Stat. 362 og 363) NV af Spitsbergen; Dybden fra 260 
118 
and terminate in a finely drawn out point (fig. 3 g). The 
terminal division is considerably longer than the 5th joint, 
and has the 1st 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, yet, upon the whole, are robust, and 
only diminish slightly towards the extremity. To the 
naked eye 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 but strong, almost spiniform hairs, which gives 
them a somewhat' rough exterior surface. The 3 coxal 
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 l / 2 times longer than the' ter- 
minal division. This last (sec fig. 3 k) is appreciably nar- 
rower, and has the tarsal joint plain cylindric in form. 
The propodal joint is , / 2 as long again, and considerably 
narrower than the tarsal joint, linear in form, and deficient 
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 shorter 
than the propodal joint, or about half the length of the 
tarsal joint, rather 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 delicate 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 
larvae 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. 
Occurrence. 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 V esteraalen ; the 2 others (Stat. 362 and 363) north-west
