De 3 bagre Fodpar er noget mindre kraftigt udviklede 
en< i hos foregaaende Art, forovrigt af den smdvanlige Byg- 
ning. 
Den rudimentsere Bagkrop (se Fig. 4 g — K) dannei 
^ Uri et yderst lidet knudeformigt Fremspring ved Enden af 
s alste Kropssegment mellem Boden af sidste Fodpar. Ved 
n0 iero Unders0gelse riser dette sig at bestaa ligesoiu al 3 
V abler, en dorsal og 2 ventrale. Disse indeslutter mellem 
Endeafsnittet af' Tarmen, der i minder paa Spidsen med 
en trekantet Aabning. Paa den nedre Side af de ventrale 
I a lvler sees 2 smaa knudeformige Fortsatser, der forestiller 
Eudimenter af et Par Lemmer. 
' 
Hannen (Fig. 4 x ) er betydelig stbrre end Hunnen 
°8 af mere langstrakt Kropsform. NaVnlig er de 2 forreste 
Segmenter kjendelig stserkere forlsengede. Legemets Be- 
'®bning er derimod lidet afvigende, skjpndt Piggene idet- 
bele syncs noget mindre fremtrsedende. 
lste Par Fplere er betydelig staerkere forlsengede end 
bos Hunnen og mere end dobbelt saa lange som 2det Par. 
Skaftets 2 ydre Led er indbyrdes nresten af e.ns Stprrelse 
°& Svoben neppe halvt saa lang som Skaftet. 
2det Fodpar, der ligesom hos Hannen af foregaaende 
^Jf udspringer fra den bagre Del af 2det Segment, er 
b'mnielig uligt samme hos Hunnen. Haanden er sserdeles 
shiv og a,f aflang Form samt i begge Ranter tiet.bosat med 
j* lu ‘ Oilier. Griberanden viser i Midten 2 dvbe Indsnit 
3e graendsede af 2 triangukere Fortsatser, hvoraf navnlig 
t * en forreste er meget stor. Foran det forreste og dybeste 
Indsnit og lige under Endekloens Insertion gaar Haanden 
Ud ‘ 2 spidse Hjorner. 
Bagkroppen (Fig. 4 h — 1) er forholdsvis noget mindre 
nndimentser end hos Hunnen, og de 2 knudeformige Appen- 
dices paa den nedre Side er her udviklede til et Par tyde- 
ifto 2-leddede og tret borstebesatte Lemmer. TTmiddelbart 
° ran Bagkroppen udgaar fra sidste Kropssegments Bugside 
^ koniske Fortsatser, som forestiller de ydre Kjonsvedhamg. 
Farven er hos begge Kjon ensformig graahvid, uden 
n °gen tvdelig Pigmentering. 
Lmngden af den aegbserende Hun er 14'"’”. Hannen 
'l'riaar en Laengde af indtil 20”"". 
Forekomst og Udbredning. Denne characteristiske 
1 f er under Expeditionen observeret paa ikke mindre end 
b forskjellige Stationer, alle tilhorende den kolde Area; 
Bybden fra 350 til 743 Favne. Paa enkelte af disse Sta- 
, l0rier forekom den i store Msengder. Det sydligste Punkt, 
v, u den er bleven observeret er i Fserp-Shetlands-Benden, 
l )aa hvilken Lokalitet den forst blev opdaget under den 
'Uelske Dightning-Expedition, det nordligste Punkt (Sta,t. 
ligger i Havet Vest af Spitsbergens Sydpynt.

The 3 posterior pairs of legs are somewhat less power- 
fully developed than is the case with those in the preced- 
ing species; for the rest, of the usual structure. 
The rudimentary abdominal division of the body (fig. 
4 q ]{) forms but an exceedingly small tuberculiform pro- 
jection. at the extremity of the last body-segment, between 
the bases of the last pair of legs. On closer examination, 
this projection is found to consist, as it were, of 3 \ a, Ives, 
one dorsal and 2 ventral. These valves enclose the terminal 
section of the intestine, which opens at the extremity with 
a triangled orifice. On the lower surface of the ventral 
valves, are seen 2 small, tuberculiform prolations, that rep- 
resent the rudiments of one or two limbs. 
The Male (fig. 4 ,r) is considerably larger than the 
female, and exhibits a more elongate form of body. Ihe 
2 foremost segments arc in particular appreciably more 
produced. On the other hand, the armature of the body 
deviates but little, though the spikes would, on the whole, 
appear to be less prominently developed. 
The 1st pair of antenna 1 are much more elongate 
than in the female, and upwards of double the length of 
the 2nd pair; the 2 outer joints of the peduncle occur al- 
most equal in length, and the flagellum is scarcely half as 
long as the peduncle. _ 
The 2nd pair of legs, 'which, as in the male of the 
preceding species, issue from the posterior part of the 2nd 
segment, differ considerably from those in the female. The 
hand is exceedingly large, oblong in form, and delicately 
ciliate along both margins. The palmar margin exhibits 
in the middle 2 deep incisions, bounded by 2 triangular 
projections, of which the foremost in particular is very 
laro-e Anterior to the foremost and deepest mcison, and 
immediately beneath the origin of the terminal claw, the 
hand juts forth as 2 sharp corners. 
The posterior division of the body (fig. 4 1: T) is, >,\ 
comparison, somewhat less rudimentary than in the female, 
and the 2 tuberculiform appendages on the lower side are 
developed as a pair of distinct two -jointed and densely 
bristle-beset limbs. Immediately anterior to the posterior 
division of the body, proceed from the ventral surface of 
the last body-segment 2 conical prolations, that represent 
the outer generative appendages. _ 
Until sexes a uniform greyish-white, with- 
out distinct pigmentation. 
Length of the ovigerous female 14“’". 
tains a length of 20"".

Oceurrence and Distribution. - This characteristic 
D ecies was taken on the Expedition at as many as 6 dif- 
rent Stations, all belonging to the cold area. Depth 
ailoi ng from 350 to 743 fathoms. At several of these 
Stations the animal occurred in great abundance. Ihe 
aost southerly point at which it has hitherto been observed 
s the Fferp-Shetland channel, the locality where the form 
vis first met with (on the English “Lightning” Expedition); 
, he most northerly point (Stub 343) lay some distance west 
if the southern extremity of Spitsbergen.
