Folerne (Fig. 1 d) har nogen Lighed med samme
hos foregaaende Art, men synes lidt spinklere. Forholdet
af Leddene er omtrent som hos hin Art, alene med den
Forskjel, at sidste Led synes noget mindre og smalere.
De falske Fodder er kun lidet længere end Legemet,
hvorved dog er at bemærke, at det undersøgte Exemplar
synes at være en Hun. Randtornerne (Fig. 1 e) er
ualmindelig tynde, dolkformige og ensformigt saugtakkede i
Kanterne, uden nogen særlig store basale Sidetænder.
Gangfodderne (se Fig. 1) er temmelig stærkt
forlængede, idet de er over 4 Gange længere end Legemet. De
er dog ikke af nogen ualmindelig Spinkelhed og afsmalnes
kun ganske svagt mod Enden; i sin hele Længde er de
besatte med meget fine, spredte Haar. Af Leddene er 2det
Lægled som sædvanlig det længste og omtrent 2’/2 Gang
længere end det terminale Afsnit. Dette sidste (Fig. 1 f)
forholder sig i Here Henseender eiendommeligt.
Tarsalleddet er saaledes forholdsvis usædvanlig kort, medens
Fodleddet udmærker sig ved en betydelig Udvikling. Det er
nemlig næsten l/s Gang til saa langt som Tarsalleddet og har
Inderkanten noget udbuet samt bevæbnet med en tæt Rad
af temmelig lange, skjøndt tynde Torner. Endekloen er
omtrent halvt saa lang som dette Led og temmelig kraftig,
med en eiendemmelig hornbrun Skygning ved Basis.
Derimod er Bikloerne saa yderst smaa og rudimentære, at de
meget let vil kunne oversees, uden Tilhjælp af stærke
Forstørrelser.
Forekomst. Det ovenbeskrevne Exemplar blev under
Nordenskjøld’s Expedition taget i det kariske Hav paa et
Dyb af 60 F.
The palpi (fig. 1 d) have some resemblance to those
in the preceding species, but appear to be a little more
slender. The relations between the joints are about the same
as in that species, with this difference only, that the last
joint seems to be somewhat smaller and more slender.
The false legs are but little longer than the body,
in relation to which it is to be noted, however, that the
specimen examined seems to be a female. The marginal
spines (fig. 1 e) are remarkably slender, dagger-shaped, and
uniformly-serrate on the edges, without any particularly
large lateral teeth at the base.
The ambulatory legs (see fig. 1) are a good deal
elongated, as they are more than 4 times longer than the
body. They are not, however, exceptionally slender, and
taper but very slightly towards the extremity; they are beset
throughout their entire length with very delicate scattered
hairs. Of the joints, the 2nd tibial joint is, as usual, the
longest, about two and a half times longer than the terminal
section. The latter (fig. If) is in many respects peculiar.
Thus, the tarsal joint is uncommonly short, whereas the
propodal joint distinguishes itself by a considerable
development, being almost half as long again as the tarsal joint,
with the inner edge somewhat arcuate and armed with a
dense series of rather long, though slender spiues. The
terminal claw is about half as long as that joint, and
rather powerful, with a peculiar horny-brown tint at the
base. The auxiliary claws, on the contrary, are so very
minute and rudimentary, as to admit of being easily
overlooked without the aid of a strong magnifier.
Occurrence. The specimen above described was
taken on Nordenskjøld’s Expedition in the Kara Sea, at
a depth of 60 fathoms.

Specific Character. Body somewhat slender, with
rather large, well separated lateral processes and 3 acuminated
dorsal projections. Cephalic segment about as long as the
3 following segments taken together, neck of moderate
length, frontal part but little expanded. Oculiferous tubercle
somewhat elevated, obtuse-conic, with the lenses of moderate
size. Proboscis the length of the cephalic segment.
Chelifori remarkably small, scape narrow-cylindric, extended
straight forward, hand hardly more than half as long,
with the fingers shorter than the palm and strongly
