meget tynd og sammensat af 6 Led. Bisvaben er neppe 
mere end halvt saa lang og 4-leddet. 
2det Par Falere (Fig. 4 b) er ubetydeligt bengere end 
I ste Par og har de 2 basale Led staerkt opsvulmede og 
del vis skjulte under Hovedslcjoldet. Skaftets naestsidste Led 
er noget udvidet mod Enden og temmelig rigeligt forsynet 
med Borster, der her ligesom overalt paa Legemet er uci- 
lierede. Svoben er tynd, 8-leddet. 
De 2 forreste Fodpar (Fig. 4 c) er indbyrdes fuld- 
kommen af samme Bygning, temmelig kraftige, med Haan- 
den af oval Form og Griberanden kort og noget skraa samt 
bagtil begrasndset af et tydeligt tandformigt Fremspring, ved 
hvis Basis er flestet on stark Torn. 
De 2 folgende Fodpar liar 3die Led forholdsvis stort 
og tiet borstebesat, de 2 sidste temmelig smaa. 
5te Fodpar har som hos de ovrige til denne Slsegt 
horende Arter Hofteleddet pladeformigt udvidet, de ovrige 
Led succesivt afsmalnende og temmelig rigeligt borstebesatte. 
6te Fodpar er naesten dobbelt saa langt, med Hofte- 
leddet nsesten elliptiskt, de ovrige Led cylindriske med 
spredte tornformige Borster; Endeldoen tynd og lige. 
Sidste Fodpar er igjen meget kort, men har Hofte- 
leddet saerdeles stort, pladeformigt, med den bagre Rand 
jevnt bueformigt boiet og utydeligt saugtakket. Den ovrige 
Del af Foden er neppe bengere end Hofteleddet og jevnt 
afsmalnende. 
Sidste Par Halefodder (se Fig. 4 e) har den ydre 
Gren stmrkt forkenget og sylfonnigt tilspidset samt besat 
med en Del simple Borster. Den indre Gren er meget 
kort, neppe mere end saa lang som den ydre. 
Halevedhamget (ibid.) er af atiang Form og ved et 
smalt Indsnit kloftet lige til Roden i 2 symmetriske Halvdele. 
Farven er hvidgraa, noget gjennemsigtig. 
Lmngden overstiger neppe 5 l / 2 mm . 
Forekomst og Udbredning. Nogle faa Exemplarer 
af denne distincte Art toges under Expeditionens 2det Togt 
ved Sydkystcn af Jan Mayen paa 15 — 20 Favnes Dyb. 
Samme Art har jeg ogsaa taget ved vor Kyst, nemlig i 
Varange r fjorden . Den er vistnok at betragto som en arktisk 
Form. 
non-ciliated bristles. The flagellum is somewhat shorter 
than the peduncle, very slender,, and composed of 6 artic- 
ulations. The secondary flagellum is scarcely more than 
half as long, and has 4 articulations. 
The 2nd pair of antonmw (fig. 4 b) are but very 
little longer than the 1st pair, and have the 2 basal joints 
greatly swollen, and in part covered by the cephalic shield. 
The penultimate joint of the peduncle is somewhat dilated 
towards the extremity, and rather abundantly provided with 
bristles, which here, as elsewhere on the body, are non- 
ciliated. The flagellum is slender, and composed of 8 ar- 
ticulations. 
The 2 anterior pairs of legs (fig. 4 c) are perfectly 
uniform in structure, rather powerful, with the hand of an 
oval form and the palmar margin short and somewhat ob- 
lique, as also posteriorly defined by a well-marked dentiform 
projection, at the base of which occurs a strong spine. 
The 2 succeeding pairs of legs have tin* 3rd articula- 
tion comparatively large and densely beset with bristles, 
the 2 last rather small. 
The 5th pair of legs have, as in the other species 
belonging to this genus, the basal joint lamelliform-dilated, 
the remaining articulations successively tapering and rather 
abundantly furnished with bristles. 
The 6th pair of legs are well-nigh double the length, 
with the basal joint almost elliptic in form, the remaining 
articulations cylindrie, with scattered spiniform bristles. 
Terminal claw slender and straight. 
The last pair of legs, again, are very short, but have 
the basal joint exceedingly large, lamelliform, with the 
posterior margin uniformly arched and indistinctly serrate. 
The remaining portion of the leg is scarcely at all longer 
than the basal joint, and tapers gradually. 
The last pair of caudal stylets (see tig. 4 e) have 
the outer branch very considerably elongate and awlshaped- 
acute, as also beset with a number of simple bristles. The 
inner branch is very short, scarcely more than one-third 
as long as the outer. 
The telson (ibid.) is oblong in form, and, by a narrow 
incision, cleft to the base into 2 symmetrical halves. 
Colour a whitish-grey, semi-translucent.

Occurrence and Distribution. — A few individuals 
of this distinct species were obtained on the 2nd cruise of 
the Expedition, oil the south-east coast of Jan Mayen, from 
a depth of 15 — 20 fathoms. The same species I have 
likewise taken on the Norwegian coast, viz. in the Varanger 
Fjord. It may no doubt be regarded as an Arctic form.
