kan indboies. Solve Haanden er betydelig kortere og sma- 
lere, uden tydeligt begrsendset Griberand, men nedentil for- 
synet med flere knudeformige Fremspring. 
De 2 folgende Fodpar udmmrker sig derved, at deres 
Hofteled ligesom paa de 3 bagerste Par er pladeformigt 
udvidet og af oval oiler skivedannet Form. 5te Fodpar er 
betydelig mindre end baade dot foregaaende og efterfolgende 
og ialmindelighed boiet opad. Sidste Led paa de 2 bagre 
Par er steerkt forlsenget og barer en kraftig krummet 
Endeklo. 
Sidste Par Halefodder er kortere end de foregaaende 
Par og kun forsynede med en enkelt kort hageformig opad- 
krummet Gren. 
Halevedhaenget er lidet, rorformigt og ved Spidsen 
bevsebnet med en Del starke Torner. 
Dyrets Farve er hvidagtig, mere eller mindre spraglet 
med brunt Pigment. 
Ltengden er omtrent 7" m . 
Forekomst. Flere Exemplarer, saavel Hanner som 
Hunner, af denne Art toges under Expeditionens 2det Togt 
paa en enkelt Lokalitet (St. 200) i Ha vet NY af Finmaken 
Pa et Dyb af 620 Favne. Et enkelt Exemplar erholdtes 
desuden S af Jan Mayen (St. 224) paa betydelig ringere 
Dyb, nemlig 95 Favne. Da begge Stationer tilhorer den 
kolde Area, er Arten utvivlsomt at betragte som en mgte 
arktisk Form.

Artscharakteristik. Legemet smalt og forltenget, noget 
nedtrykt, med meget smaa Epimerer. Hovedet fortil af- 
stumpet, med tilspidsede Sidehjorner. lste Par Epimerer 
gaaende fortil ud i en tilspidset Flig. De 3 forreste Bag- 
kropssegmenters Sideplader med det nedre bagre Hjorne 
udtrukket i en skarp Spids. Ingen Dine, lste Par Folere 
tynde og forlamgede, med Skattets sidste Led neppe 1 ) J j saa 
langt som 2det, Svaben omtrent af Skaftets Lsengde, Bi- 
svoben meget liden, 2-leddet. 2det Par Folere betydelig 
kortere end lste Par, hos Hannen kraftigere udviklede, 
against which the terminal claw admits of being bent in. 
The hand itself is considerably shorter and narrower, with- 
out any well-defined palmar margin, but furnished below 
with several tuberculiform projections. 
The 2 succeeding pairs of legs are characterized by 
the basal joint occurring, as in the 3 posterior pairs, lamelli- 
form-dilated, and of an oval or discoid form. The 5th pair 
are considerably smaller than either the preceding or the 
succeeding, and, as a rule, upturned. The last joint of the 
2 posterior pairs is greatly produced, and bears a powerful 
curving terminal claw. 
The last pair of caudal stylets are shorter than the 
preceding, and furnished merely with a single short ungui- 
form upward-curving branch. 
The telson is small, tubular, and armed at the point 
with a number of strong spines. 
Colour of animal whitish, more or less variegated 
with brownish pigment. 
Length about 7 mm . 
Occurrence. — Several examples of this species — both 
male and female — were brought up on the 2nd cruise of 
the Expedition, in a single locality (Stat. 200), north-west of 
Finmark, from a depth of 620 fathoms. A single specimen 
was also taken south of Jan Mayen (Stat. 224), at a much 
less considerable depth, viz. 95 fathoms. Both Stations 
having belonged to the cold area, the species must unques- 
tionably be regarded as a true Arctic form.
