I 
Arter. idet her 3die Led er fuldkommen saa langt som 
2det, og de 2 sidste Led indbyrdes af ens Lrengde og til- 
sammentagne lig 3die. 
De falske Fodder hos Hannen (Fig. 1 f) er, lige ud- 
strakte, omtrent af Legemets Lsengde og af en temmelig 
spinkel Form. 5te Led er stserkt forhcnget og udvides 
ganske successivt mod Enden, uden her at vise en saadan 
abrupt Opsvulmning som hos de 2 foregaaende Arter. 
Ligcdedes er de til dette Led faestede Forster af et mere 
uniformt Udseende og betydelig kortere og finere end hos 
hine Arter. Kandtornerne paa Endedelen (Fig. 1 g) er 
forholdsvis smaa, stumpt lancetformige og uregelmsessigt 
rundtakkede i Kanterne. 
Gangfodderne (se Fig. 1) er kjendelig spinklere end 
hos de 3 foregaaende Arter, hvorved dog er at nuerke, 
at det undersogte Exemplar er en Han. De er ikke iuldt 
3 Gange kengere end Legemet og, navnlig i sit ydre laiti, 
tset laadne af temmelig lange og stive Haar. Laarleddet 
har i Inderkanten 3 temmelig store, afrundede Knuder, 
del- er indskrsenkede til det basale Parti af Leddet. 2det 
Laigled er af smal linear Form og omtrent 2‘/ 2 Gang 
langere end det terminale Afsnit. Dette sidste (se Fig. 
1 h) ligner noget samme hos Ch. spinosum, men har Tar- 
salleddet forholdsvis langere. Fodleddet er ikke fuldt 
dobbelt saa langt og tiltager lidt i Tykkelse mod Enden. 
I Inderkanten har det en Rad af 12 — 14 tynde iornei 
af noget ulige Lsengde, de i Midten kengst. Endekloen 
er forholdsvis kort, neppe mere end halvt saa lang som 
Fodleddet, men temmelig kraftig og stark! krummet ved 
Basis. Biklperae er som hos Ch. spinosum vel udviklede 
og omtrent halvt saa lange som Kloen. 
Ingen af de 2 undersogte Exemplarer var segbaerende, 
og om de ydre iEgmassers Form kan saaledes intet anfores. 
Forekomst. 2 Exemplarer af denne A.rt, begge 
Hanner, toges under Nqrdhavs-Expeditionens sidste Togt 
i Havet V. af Finmarken (Stat. 200) paa et Dyb af 620 F. 
Da Stationen tilhorer den kolde Area, er Arten utvivlsomt 
at betragte som en agte arktisk Form.

| preceding species, the 3rd joint being in this animal fully 
: as long as the 2nd, and the 2 last joints uniform in length 
and taken together equal to the 3rd. 
The false legs in the male (fig. 1 f) are, when fully 
extended, about same length as the body and rather slender 
in form. The oth joint is very' much elongated, and 
expands quite gradually towards the end without exhibiting 
there so abrupt a tumefaction as in the 2 preceding spe- 
cies. Moreover, the bristles affixed to that joint present 
a more uniform appearance than in those said species. The 
marginal spines on the terminal part (fig. 1 g) are com- 
paratively small, obtuse-lanceolate, and irregularly serrated 
on the edges. 
The ambulatory legs (see fig. 1) are appreciably more 
slender than in the 3 preceding species ; we must, how- 
ever, bear m mind that the specimen examined was a male. 
They are not quite 3 times longer than the body, and, 
more particularly in their outer part, densely hirsute with 
rather long and stiff hairs. The femoral joint bears on 
the inner edge 3 rather large rounded tubercles, confined 
in position to the basal part of the joint. The 2nd tibial 
joint is narrow linear in form, and about 2 1 / 3 times 
longer than the terminal section. The latter (see fig. 1 h) 
somewhat resembles that part in Ch. spinosum, but has 
the tarsal joint relatively longer. The propodal joint is 
not quite twice as long, and increases in thickness towards 
the extremity. On the inner edge it bears a series of 
12—14 slender spines, somewhat unequal in length, those 
in the middle being longest. The terminal claw is relatively 
short, scarcely more than half as long as the propodal 
joint, but rather powerful and sharply curved at the base. 
The auxiliary claws are well developed, as in Ch. spinosum, 
and about half as long as the main claw. 
Neither of the 2 specimens examined was ovigerous, 
and nothing can be said therefore respecting the form of 
the outer egg-masses. 
Occurrence. Two specimens of this species, both 
males, were taken on the last cruise of the North- Atlantic 
Expedition (St. 200), in the sea west of Finmark, at a 
depth of 620 fathoms. As this Station lies in the cold 
area, the species must unquestionably be regarded as a 
true Arctic, form.
