(Fig. 2 a) betvdelig stserkere forkengede end kos Hunnen, 
omtrent l / 4 lsengere end Legemet og har som ssedvanlig 
5te Led lsengst. Eudedelen ei’ kortere end dette Led. og 
har Randtornerne (Fig. 2 f) af bred lancetdannet Foim, 
med en regelmaessig Rad af stserke Saugtakker i h\ei 
Kant. 
Gangfodderne er (se Fig. 2) ualmindelig spinkle og 
forkengede, nsesten 5 Gange lsengere end Logemet, og be- 
satte med spredte, temmelig lange Haar. Af Leddene er 
som ssedvanlig 2det Lmgled dot lsengste og ganske over- 
ordentlig tyndt. Det terminal Afsnit (Fig. 2 g) er neppe 
l/j saa langt og har Tarsalleddet kjendelig lsengere end 
Fodleddet, begge af smal lineser Form og besatte med 
spredte Smaaborster. Eudekloen er neppe mere end halvt 
saa lang som Fodleddet, men temmelig stserk og tydeligt 
leformigt tilskjserpet. Biklperne udmserker sig i hoi Giad 
ved sin betydelige Storrelse, idet de er 2 / 3 saa lange som 
selve Kloen. 
De ydre rEgrnasser forefindes kun i et enkelt Par 
og smdvanligvis f'sestede omkring de falske Fodders 5te 
Led. De er (se Fig. 2 a) forholdsvis smaa og af kugle- 
daunet Form, hvorimod de i dem indeholdte -Eg er af 
ganske ualmindelig Storrelse. 
Forekomst. .Teg har fundet denne Art ikke saa 
sjelden langs vor Vestkyst. og nordlig til Lofoten, paa et 
Dyb af 40— 100 F. Under Nordhavs-Expeditionen toges 
den enkelt vis paa 2 Stationer, den ene (Stat. 262) 0st af 
Yardo, den anden (Stat. 290) omtrent midtveis raellem 
Finmarken og Beeren Biland; Dybden fra 148 til 191 F. 
Udbredning. Arten er udbredt til Nordamerikas 
Gstkyst, hvor den er taget i Golf'en ved Maine paa 85 
115 F. D. (Wilson). At domme efter denne Udbredning 
i Forbindelse med dens Forekomst i Uavet udenfor Fin- 
marken, maa den ulvivlsomt ansees for en oprindelig ark- 
tisk Form.

Artscharacter. Legemet af forholdsvis undeissetsig 
Form. Hovedsegmentet neppe lsengere end de 2 folgende 
Segmenter tilsammen; Halsen forholdsvis kort og tyk; 
Pandedelen kun lidet udvidet. 0ieknuden meget lav. af- 
rundet. Snabelen kortere end Hovedsegmentet, cylindrisk. 
Saxlemmerne forholdsvis smaa, Haanden neppe saa lang 
som Skaftet, af aflang oval Form, Fingrene kortere end 
Palmen. Folerne korte og tykke, tset haarede, 2det og 
3 die Led af ens Storrelse, sidste noget lsengere end nsest- 
sidste; begge tilsammen saa lange som 3die. De falske 
Fodder hos Haunen noget lsengere end Legemet, Endedelen 
male (fig. 2 a), they are considerably more elongated than- 
in the female, about one-fourth longer than the bod\ , and 
have, as usual, the 5th joint longest. The terminal part 
is shorter than that joint, with the marginal spine's (fig. 
2 f), broad-lanceolate in form and bearing a regular series 
of strong saw-teeth on either edge. 
The ambulatory legs (see fig. 2) are uncommonly 
slendfer and elongated, almost 5 times longer than the body, 
and beset with scattered, rather long hairs. Of the 
joints, the 2nd tibial joint is, as usual, the longest, and 
quite remarkably slender. The terminal section (fig. 2 g) 
is hardly one-fourth as long, and has the tarsal joint ap- 
preciably longer than the propodal joint, both narrow- 
linear in form and beset with scattered minute setae. The 
terminal claw is hardly more than half as long as the 
propodal joint, but rather powerful and distinctly falci- 
formly sharpened. The auxiliary claws prominently [dis- 
tinguish themselves by their considerable size, as they are 
two-thirds as long as the claw itself. 
The outer egg-masses occur as a single pair only, 
and. in general, affixed round the 5th joint 'of [the false 
legs. They are relatively small (se fig. 2 a) and globular 
in form, whereas the ova they contain are of [quite a 
remarkable size. 
Occurrence. I have not infrequently met with this 
species along the West Coast of Norway, and as far north 
as Lofoten, at a depth of from 40 to 100 fathoms. On 
the North- Atlantic Expedition solitary specimens were 
taken at 2 Stations, the one (Stat. 262) east of Yardo, 
the other (Stat. 290) about midway between Finrnark and 
Beeren Eiland; depth from 148 to 191 fathoms. . 
Distribution. The species ranges as far as the east 
coast of North America, where it has been found in the 
Gulf of Maine at a depth of 85—115 fathoms (Wilson). 
To judge from this distribution, along with its occurrence 
off the coast of Finrnark, the animal must doubtless be 
regarded as originally an Arctic foim.

Specific Characters. Body comparatively thickset in 
form. Cephalic segment hardly longer than the 2 suc- 
ceeding segments taken together; neck relatively short and 
thick; frontal part but little expanded. Oculiferous tubercle 
very low, rounded. Proboscis shorter than the cephalic 
segment, cylindric. Chelifori comparatively small, hand hardly 
as long as the scape, oblongo-oval in form, fingers shorter 
than the palm. Palpi short and thick, densely hairy, 2nd and 
3rd joints of equal size, last joint somewhat longer than the 
penultimate one ; both taken together as long as the 3rd. False 
legs in the male somewat longer than the body, terminal part
