hos foregaaende Art, men er talrigere og orduede i flere 
Rader; de i den inderste Rad — de egentlige Randtorner 
- — er dog betydelig storre end de i de ovrige. 
Gangfodderne (se Fig. 2) er af spinkel Form, omtrent 
dobbolt saa lange som Legemet (udon Snabelen), og tmt 
besatte med fine, ensformigt ndviklcde Haar. Hos Hunnen 
er 2det Hofteled sserdeles stserkt, nmsten bkeref'ormigt op- 
blast og fyldt med store iEgceller, medens dette Led hos 
Hannen (se Fig. 2 p) er smalt og af linear Form; hos 
begge Kjon er det mere end dobbelt saa langt som de 2 
pvrige Hofteled tilsammen. Laarleddet er omtrent af Hofte- 
partiets Lsengde og- hos begge Kjpn af smal linear Form ; 
hos Hannen liar det nser Basis en stumpt al'rundet Knude 
(Fig. 2 q), som ganske mangier hos Hunnen. Af de 2 
Lsegled er det 2det noget lsengere end det lste og omtrent 
af Laarleddets Langde, begge meget. smale, lineare. Ende- 
partiet (Fig. 2 r. 2 s) er omtrent halvt saa langt som 2det 
Laegled og har Tarsalleddet meget kort, medens Fodleddet 
er temmelig stserkt forlanget og nsesten lige. 
De til de falske Fodder hos Hannen fsestede rEg er 
(se Fig. 2 c) forholdsvis meget store, kugleformige, og faa 
i Antal, neppe over 8 — 12 Stykker. De er enkeltvis grup- 
perede omkring 4de Led, uden at vsere omgivne af nogen 
failles Ombyllingsmembran. 
Legemet er i levende Tilstand af hvidagtig Farve og 
temmelig gjennemsigtigt, saa at flere af de indre Dele 
skinner mere eller mindre tydeligt igjennom Integumeu- 
terne. Saaledes er, naar Legemet sees nedenfra (Fig. 2 b) 
den liele Buggangliekjade meget ioinefaldende. Den be- 
staar af 5 vel adskilte Ganglier, hvoraf det forreste er af 
temmelig smal og forlsenget Form. jUo fra Ganglierne 
ndgaaende Hovednerver er ligeledes tydelig at forfolge. 
Forekomst. Af denne characteristiske Form blev 
under Expeditionen talrige Exemplarer indsamlede, navnlig 
i stor Mtengde paa ’de paa Bundskraben hestede Svab- 
berter. Arten er observeret paa ikke mindre end 5 for- 
skjellige Stationer, spredte omkring i det af os bereiste 
Havstrog fra den 63de til den 78de Bredegrad. Af Sta- 
tionerne ligger 2 (St. 35 og 53) i Havet mellem Norge. paa 
den ene Side og Fmroerne og Island paa den anden, en 
3die (St. 205) NY af Lofoten, de 2 ovrige (St. 303 og 
353) lsengere Nord i Havet mellem Spitsbergen og Beeren 
Eiland paa den ene Side og Gronland og Jan Mayen paa 
den anden. Dybden fra 1081 til 1539 Favne. Alle Sta- 
tioner tilhorer den kolde Area. 
Udbredning. Da denne Form hidtil ikke er obser- 
veret af andre Forskere, kan om dens Udbredning for 
Tiden kun siges, at den synes at vsere indskrsenket til den 
dybe, med iskoldt Vand paa Bunden fyldte Indssenkning i 
Nordhavet, der ligger vestenom de store Havbanker og 
disses Fortssettelse mod Nord forbi Beeren Eiland og 
Spitsbergen. Gstenfor den 13de Lsengdegrad er den hidtil 
ikke observeret. 
(fig. 2 o) exhibit a similar appearance as in the preceding 
species, but are more numerous and arranged in several 
series; those in the innermost series — the real marginal 
species — are, however, considerably larger than the others. 
The ambulatory legs (see fig. 2) are slender in form, 
about twice as long as the body (excluding the proboscis), 
and are closely beset with fine, uniformly developed 
setae. In the female the 2nd coxal joint is very much, 
almost vesicularly inflated, and is filled with large ovicells, 
whilst the same joint in the male (se fig. 2 p) is narrow 
and linear in form; in both sexes it is twice as long as 
the 2 other coxal joints taken together. The femoral joint 
is about the length of the coxal part, and in both sexes 
is narrow linear in form; it has, in the male, near the 
base, a bluntly rounded nodule (fig. 2 q), which is quite 
absent in the female. Of the 2 tibial joints the 2nd is 
somewhat longer than the 1st one, and about the length 
of the femoral joint, both very narrow, linear. The ter- 
minal part (fig. 2 r, 2 s) is about half the length of the 
2nd tibial joint and has the tarsal joint very short, while 
the propodal joint is pretty strongly elongated and almost 
straight. 
The ova attached to the false legs in the male (see 
fig. 2 c) are relatively very large, globular in shape, and 
few in number, scarely more than 8 — 12. They are 
grouped singly, round the 4th joint, without being enve- 
loped in any common enclosing membrane. 
The body is, in the live state, of whitish colour and 
pretty transparent, so that several of the internal organs 
appear more or less distinctly visible through the integu- 
ments. Thus, when the body is viewed from below (fig. 
2 b), the entire chain of ventral ganglia is very prominent. 
It consists of 5 well separated ganglia, of which the foremost 
is of rather narrow and elongate form. The chief nerves 
issuing from the ganglia may also be distinctly traced. 
Occurrence. Numerous specimens of this charac- 
teristic form were collected during the expedition, especi- 
ally attached in great numbers to the swabs secured to 
the dredge. The species was observed at not less than 5 
different stations scattered about in the tracts of the ocean 
cruised in, from the 63rd to the 78th parallels of latitude. 
Of the stations, 2 (St. 35 and 53) are situated in the 
ocean between Norway on the one side and the Faeroe 
Islands and Iceland on the other; a 3rd (St. 205) to the 
N. W. of Lofoten; the 2 others (St. 303 and 353) farther 
north, in the ocean between Spitzbergen and Beeren Eiland 
on the one side and Greenland and Jan Mayen on the 
other. Depth from 1081 to 1539 fathoms. All the stations 
pertain to the cold area. 
Distribution. As this form has not, hitherto, been 
observed by other naturalists, it can, for the present, only 
be said of its distribution, that it appears to be confined to 
the deep basin filled at the bottom with ice-cold water that 
exists in the North Sea, situated to the west of the great 
ocean banks and their continuation northwards past Beeren 
Island and Spitzbergen. To the east of the 13th degree 
of longitude it has not hitherto been observed.
