0vrige Led tilsammen og af oval Form, med den forreste 
Band jevnt buet, den bagre naesten lige og forsynet med 
3 smaa tandformige Fremspring, hvoraf de 2 yderste staar 
t»t sammen og red et betydeligt Mellemrum er skilte fra 
det overste. Endekloen er saerdeles stserk, leformig krummet, 
og lsegger sig, naar den indboies, med Spidsen ind mod 
det Overste af de ovenomtalte tandformige Fremspring. 
De til 3 die og 4de Segment fsestede Gjolleblade er 
forholdsvis smaa og smale og rager fortil og bagt.il noget 
ud over Brystposen. 
De 3 bagre Fodpar er kraftigt udviklede og tiltager 
successivt noget i Laengde bagtil. Sidste Led er som smd- 
vanlig subcheliformt eller danner et Slags Haand, med en 
Afsats ved Basis i den forreste Kant, mod hvilken Ende- 
kloen kan indboies. 
Hamen (se Fig. 3 a') er af forholdsvis spinklere og 
mere langstrakt Form end Hunnen og liar de 4 forreste 
Segmenter nmsteu fuldkommen glatte eller kun med yderst 
svage Spor af de Kuuder, som Andes her hos Hunnen, hvor- 
imod de 3 bagerstc Segmenter riser en lignende Beveebning. 
Af Segmenterne er navnlig de 2 forreste kjendelig sfoerkere 
forlsengede end hos Hunnen, dog saaledes, at det (indbyrdes 
Forhold mellem begge er temmelig uforandret. 
lste Par Folere skiller sig fra samme Los Hunnen 
derved, at Skaftets Led er noget fortykkede paa Midten, 
sammentrykte og i Kanterne Ant- cilieredc. 
2det Fodpar, der ellers [ileier at vrere meget forskjel- 
ligt hos begge Kjon, er her naesten noiagtig af samme Ud- 
seeude som hos Hunnen, alene med den Forskjel, at Basal- 
leddet er noget mere forlamget. Derimod udspringer det 
ikke som hos Hunnen fra det forreste Parti af 2det Seg- 
ment, men kjendeligt bag Midten af dets Liengde. 
Legemet er hos begge Kjon temmelig gjennemsigtigt, 
gulagtigt, og navnlig hos Hunnen marmoreret med storre 
uregelmmssige morkebrune Shatteringer, der delvis danner 
afbrudte Tvserbaand over Kroppen. 
Lmngden af den aegbserende Hun er 12 mra . Hannen 
er noget storre og opnaar en Laengde af 17 mm . 
Forekomst. Nogle faa Exemplarer af denne Art blev 
under Expeditionens sidste Togt tagne paa 2 forskjellige 
Stationer, den ene (Stat. 315) beliggende i Havet NY af 
Beeren Eiland, den anden (Stat. 336) mer Sydpynten af 
Spitsbergen. Dybden fra 70 til 180 Fame. Exemplar erne 
fandtes fastsiddende paa Hvdroider optagne med Bundskraben 
fra klippefuld Bund. 
Skjoudt ingen at disse Stationer egentlig til borer den 
kolde Area, er man dog af Stationernes hoie nordlige Brede 
berettiget til at betragte Arten som en arktisk Form. 
section, or hand, is prodigiously developed, being longer 
than all the other joints taken together, oval in form, with 
the anterior margin evenly arched,)) the posterior almost 
straight and furnished with 3 small dentiform projections; 
of which the 2 outer ones occur close together, separated 
by a considerable interspace from the uppermost. The 
terminal claw is remarkably powerful, falciform, and im- 
pinges, when bent in, against the uppermost of the aforesaid 
dentiform projections. 
The branchial lamella? attached to the 3rd and 4th 
segments are comparatively small and thin, projecting, both 
anteriorly and posteriorly, over the marsupium. 
The 3 posterior pairs of legs are powerfully devel- 
oped, and increase somewhat in length posteriorly. The 
last joint is,* as usual, subcheliform, and forms, as it were, 
a hand, with a ledge at the base on the anterior margin, 
against which the terminal claw admits of being bent in. 
The Male (see Ag. 3 x) has comparatively a more 
slender and elongate form than the female, the 4 anterior 
segments being almost perfectly smooth, or exhibiting but 
very faint traces of the tubercles observed there in the 
female, whereas the 3 hindmost segments are furnished with 
a similar armature. Of the segments, the 2 foremost occur 
in particular more produced than in the female, yet in such 
manner that the relation between the two is very much 
the same. 
The 1st pair of antennae differ from those of the female 
in the joints of the peduncle being somewhat incrassated 
along the middle, compressed, and finely ciliated on the edges. 
The 2nd pair of legs, which, as a rule, are very dif- 
ferent in the two sexes, have almost exactly the same appear- 
ance as in the female, the only deviation consisting in the 
basal joint being a trifle more elongate. This articulation 
does not however" originate from tlxe foremost part of the 
2nd segment as in the female, but appreciably posterior to 
its longitudinal middle. 
The body is in both sexes well-nigh translucent, yel- 
lowish, and, more particularly in the female, relieved with 
large, irregular, dark-brown marbled shadings, that form in 
part transversal bands across the body. 
Length of the ovigerous female 12*"". The male is 
somewhat larger, attaining a length of 17"™’. 
Occurrence. — A few examples of this species were 
taken on the last cruise of the Expedition, at 2 different 
Stations, the one (Stat. 315) north-west of Beeren Eiland, 
the other (Stat. 336) near the southern extremity of Spits- 
bergen; depth ranging from 70 to 180 fathoms. The speci- 
mens were found attached to Hydroids, brought up in the 
dredge from a rocky bottom. 
Though neither of the said Stations strictly belonged 
to the cold area, their high northern latitude warrant our 
assuming the species to be an Arctic form.
