paa begge Par af ens Udseende og Lamgde, stserkt afsmal- 
nende mod Spidsen og bestaaende af 5 langstrakte Led. 
De 2 forreste Fodpar er mindre kraftigt udvildede end 
hos de 2 foregaaende Arter, med simpelt ovale Hmnder 
uden Torner, men besatte alene med fine Borster. De 3 
bagerste Par er indbyrdes mesten af ens Lsengde og har 
Hofteleddet temmelig bredt. 
Halefodderno og Halevedhmnget viser den s'sedvanlige 
Bvgning. 
Dyrets Farve er overall ensformig livid, uden Spor af 
nogen Pigmentering. 
Lmngden af det undersogte Individ er kun 3"”". 
Forekomst. Et enkelt Exemplar af mervmrende Art, 
en efter Udseendet fuldt udviklet Hun, blev under Expedi- 
tionens sidste Togt taget i Havet XV af Finmarken (St. 
295) fra det betydelige Dyb af UlOFavne. Stationen til- 
borer den kolde Area.

Artseharacteristik. Legemet smalt, nedtrykt, med 
Sferdcles smaa Epimerer. Hovedets Sidelober brede, stump- 
vinklede. De 3 forreste Bagkropssegmenters Sideplader 
meget smaa. 0inene store, afrundet ovale, med mqrkt Pig- 
ment. Folerne omtrent af ens Storrolso, mere end halyt 
saa lange som Legemet, bagtil med taette Borsteknipper; 
Svoben paa lste Par saa lang som Skaftets 2 sidste Led 
tilsaiumen, 12-leddet. lste Fodpar meget lidet og svagt 
bygget, med liden, ruesten qvadratisk Haand; 2det Par be- 
tydelig stmrkere udviklet, hos Hannon overordentlig stort, 
med 4de Led (carpus) staerkt opsvulmet og urns ten dobbelt 
saa langt som bredt samt gaaende nedad ud i en fortil- 
rettet dolkformig Fortsats, der naar til Enden af Haaden; 
dennes nedre Rand crenuleret. De fplgende Fodpar alle 
med pladeformigt ndvidet Hofteled; sidste Leal paa de bagerste 
I ar staerkt forlamget. Sidste Par Halefoddor korte, med 
en enkelt liden hageformig Gren. Halevedhsenget lidet. ror- 
lormigt. Farven hvidagtig med sparsomt brunligt Pigment. 
Lamgden 7 mm . 
and nearabout half as long as the 1st joint of the flagellum ■ 
The flagellum itself is on both pairs uniform in length 
and appearance, tapers rapidly toward the extremity, and 
consists of 5 elongated joints. 
The 2 foremost pairs of legs are less powerfully de- 
veloped than in the 2 preceding species, having simple, 
oval hands, without spines, merely furnished with delicate 
bristles. The 3 posterior pairs are almost equal in length, 
and have the basal joint rather broad. 
Hie caudal stylets and the telson exhibit the usual 
structure. 
The colour of the animal is everywhere a uniform 
white, without the slightest trace of pigmentation. 
Length of the specimen examined only 3 mm . 
Occurrence. — One individual only of the present 
species — to judge from its appearance a fully developed 
female — was brought up, on the last cruise of the Ex- 
pedition, north-west of Finmark (Stat. 295), from the con- 
siderable depth of 1110 fathoms. The Station lay in the 
cold area.

Specific Character. — Body slender, depressed, with 
exceedingly small epimera. Lateral lobes of head broad, 
obtuse-angled. Lateral plates of the 3 anterior abdominal 
segments very small. Eyes large, rounded oval, with dark 
pigment. Antenme about equal in size, more than half 
as long as body, furnished posteriorly with dense fascicles 
of bristles; flagellum on 1st pair twelve-jointed, and as 
long as the last 2 joints of the peduncle taken together, 
hirst pair ot legs very small and feeble in structure, 
with hand diminutive, well-nigh quadrate; 2nd pair much 
more powerfully developed, in male remarkably large, with 
4th joint (carpus) greatly swollen, almost twice as long as 
broad, and jutting down in the form of a forward-directed, 
mucroniforni projection, attaining the extremity of the hand, 
which has the lower margin crenellated. Succeeding pairs 
ot legs all with basal joint lamelliform-dilated ; last joint 
on hindmost pair exceedingly elongate. Last pair of caudal 
stylets short, with a small unguiform branch. Telson small, 
tubular. Colour whitish, with scattered brownish pigment.
