bugtede samt ender i en fint udtrukken Spids (Fig. 3 g).
Endepartiet er betydelig længere end 5te Led og har lste
Led størst saint besat med lignende Borster som de paa
foregaaende Led. De paa de 4 ydre Led fæstede
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 sædvanlige
Sidetænder.
Gangfodderne (se Fig. 3) er vistnok af betydelig
Længde, idet de er over 3 Gange længere end Legemet,
men dog idethele temmelig robuste og kun lidet
afsmalnende mod Enden. De ser for det blotte Øie ganske
glatte ud. 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
omtrent dobbelt saa langt som Hoftepartiet og udmærker sig
ikke hos Hunnen ved nogen paafaldende Opsvulmning,
saaledes som hos Arterne af foregaaende Slægt, skjøndt det
er noget tykkere end hos Hannen. 2det Lægled afsmalnes
ganske svagt mod Enden og er omtrent 21/2 Gang længere
end det terminale 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 lineær Fonn og mangler
tydelige Torner i Inderkanten, hvorimod det ligesom
Tarsalleddet er rundt om besat med samme Slags smaa
pigformige Haar som paa den øvrige Del af Foden.
Endekloen er betydelig kortere end Fodleddet, eller omtrent af
Tarsalleddets Længde, temmelig smal og jevnt krummet,
gaaende ud i en sylskarp Spids. Bikløerne synes ved
förste Øiekast ganske at mangle. Foist ved stærk
Forstørrelse (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
udklækkede Larver i alle Udviklingsstadier; ja selv længe
efter at Ungerne har tilbagelagt Larvestadiet og opnaaet
en meget anselig Størrelse, træffer man dem fastklamrede
til Hannens Legeme. Saavel hos Han som Hun er
Fødderne og tildels ogsaa Kroppen ofte besat med forskjellige
pseudoparasitiske Organismer, især Polyzoer.
Forekomst. Af denne characteristiske Fonn blev
talrige Exemplarer indsamlede under
Nordhavs-Expedi-tionens samtlige 3 Togter. Vi har noteret den fra 5
forskjellige Stationer, tildels beliggende i betydelig Afstand
fra hverandre. En af disse (Ståt. 18) ligger i Havet
mellem Færøerne og Norge; en anden (Ståt. 48) Øst af
Island; en 3die (Ståt. 192) Nord af Vesteraalen, de 2 øvrige
(Ståt. 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 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
considerable 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
examination with a powerful magnifier, they, however, appear
closely beset throughout their entire length with
particularly 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 21/2 times longer than the
terminal division. This last (see fig. 3 k) is appreciably
narrower, and has the tarsal joint plain cylindric in form.
The propodal joint is 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 abont 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
rudiment 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.
Occurrence. Of this characteristic fonn 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
distance from each other. One of those (Ståt. 18) is situated
in the ocean between the Faroe Island and Norway; a
second (Ståt. 48) east of Iceland; a third (Ståt. 192) north
of Vesteraalen: the 2 others (Ståt. 362 and 363) north-west
