Fclerne (Fig. 1 d) liar nogen Liglied 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 lamgere end Legemet, 
hvorved dog er at bemserke, at det undersogte Exemplai 
synes at vi.ere en Hun. Randtornerne (Fig. 1 e) er ual- 
mindelig tynde, dolkformige og ensformigt saugtakkede i 
Kanterne, uden nogen sterlig store basale Sidetender. 
Gangfoddcrne (se Fig. 1) er temmelig stserkt forlien- 
gede, idet de er over 4 Gange ltengere end Legemet. De 
er dog ikke af nogen ualmindelig Spinkelhed og afsmalnes 
kun ganske svagt mod Enden; i sin hele Lsengde er de 
besatte med meget fine, spredte Haar. At Leddene er 2det 
Lregled som saedvanlig det lamgste og omtrent 2 */ 2 Gang 
lsengere end det terminale Atsnit. Dette sidste (Fig. 1 1 ) 
forholder sig i Here Henseender eiendommeligt. Tarsal- 
leddet er saaledes forholdsvis ussedvanlig kort, medens Fod- 
leddet udmierker sig ved en betydelig Udvikling. Det er 
nemlig nrnsten 1 /'a Gang til saa langt som r l arsalleddet og kai 
Inderkanten noget udbuet saint bevsebnct med en tuet Rad 
af temmelig lange, skjoudt tynde Tomer. Endekloen ei 
omtrent halvt saa lang som dette Led og temmelig kraftig, 
med en eiendemmelig hornbrun Skygning ved Basis. Der- 
imod er Bikloerne saa yderst smaa og rudimentsere, at de 
meget let vil kunne oversees, uden Tilhjaelp af stserke For- 
storrelser. 
Forekomst. Det ovenbeskrevne Exemplar blev under 
Nordenskjpld’s Expedition taget i det kariske Hav paa et

Artscharacter. Legemet noget smaekkert, med tem- 
melig store vel skilte Sidefortsatser og 3 tilspidsede dorsale 
Fromspring. Hovedseginentet omtrent saa langt som de 3 
folgende Segmenter tilsammen, Halsen af middelmaadig 
Lamgdc, Pandedelen kun lidet udvidet. Gieknuden noget 
opboiet, stump konisk, med Lindserne at middelmaadig 
Storrelse. Snabelen af Hovedsegmentets Lrnngde. Sax-

The palpi (fig. 1 d) have some resemblance to those 
in the preceding species, but appear to be a little moie 
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 slendei. 
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. Hie 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. 1 f) is in many respects peculiar. 
Thus, the tarsal joint is uncommonly short, whereas the pro- 
podal joint distinguishes itself by a considerable develop- 
ment, 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 spines. 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 over- 
looked without the aid of a strong magnifier. 
Occurrence. The specimen above described was 
taken on Nordenskjold’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. Cheli- 
fori remarkably small, scape narrow-cylindric, extended 
straight forward, hand hardly more than half as long, 
with the fingers shorter than the palm and strongly
