synes ikke, saavidt det kunde sees, i nogen vaesentlig Grad 
at skille sig i sin Bygning fra sarnine hos den typiske Art. 
Do 3 bagerste Fodpar er af en overordentlig robust 
Bygning og indbyrdes omtrent af ens Lrnngde. Hofteleddet 
er sserdeles stort, nsesten firkantet, med det nedre bagre 
Hjorne noget udtrukket og bredt afrundet. Af de ovrige 
Led er navidig det 3die sserdeles bredt og sammentrykt, med 
den bagre Band stserkt buet. Endekloen er ganske kort. 
if det Par Halefodder (se Fig. 3 og 3 a) udmserker sig 
ved den betydelige Brede og stserkt sammentrykte Form af 
Stammen. Greneno er som paa lste Par simpelt koniske, 
uden Burster eller Tomer. 
Sidste Par Halefodder (ibid.) er ganske rudimentsere 
og saa sraaa, at de neppe overrager Stammen paa det fore- 
gaaende Par. De er imidlertid som de ovrige Par tve- 
grenede, med Grenene sserdeles smaa og korte. 
Halevedhaenget (ibid.) er kort og bredt, rnesten fir- 
kantet, og ikke som hos den typiske Art dybt indskaaret, 
men kun i Enden ganske svagt udrandet. 
Farven var hos det friskt indfangede Exemplar hvid- 
agtig uden nogen tydelig Pigmentering. 
Lsengden af det erholdte Exemplar er 
Forekomst og Udbredning. — 1 enkelt Exemplar, 
efter Udseende at do mine en Han, af denne meget distinkte 
Art toges under Expeditionens 2det Togt i Havet Vest af 
Lofoten (Stat. 251) fra et Dyb af 634 Favne. 1 ganske 
ungt Exemplar, der synes at tilhqre samme Art, bar jeg 
tidligere taget ved Finmarkens Kyst paa 150 — 200 Favnes 
Dyb. Da den ovenomtalte Station tilliOrer den koldo Area, 
er vistnok Arten at betragte som en arktisk Form.

but they did not appear to differ essentially in structure 
from those in the typical form. 
The 3 posterior pairs of legs are remarkably robust 
in structure and well-nigh uniform in length. The basal 
joint is exceedingly large, almost quadrate, with the lower 
posterior corner somewhat produced and broadly rounded. 
Of the remaining articulations, the 3rd, in particular, is 
exceedingly broad and compressed, with the posterior margin 
very arcuate. The terminal claw quite short. 
The 2nd pair of caudal stylets (see figs. 3, 3 a) are 
distinguished by the considerable breadth and greatly com- 
pressed form of the trunk. The branches are, as in the 
1st pair, simple conic, without either bristles or spines. 
The last pair of caudal stylets (ibid.) are quite rudi- 
mentary, and so small as scarcely to project beyond the 
trunk of the preceding pair. They are, however, as in the 
other pairs, biramous, with the branches exceedingly small 
and short. 
The telson (ibid.) is short and broad, almost quadrate, 
and not, as in the typical species, deeply incised, having 
merely a slight emargination at the extremity. 
Colour in the recently taken specimen whitish, with- 
out any distinct pigmentation. 
Length of the specimen secured 7 1 // 1 '". 
Occurrence and Distribution. — One individual only 
— to judge by the appearance a male — of this very 
distinct species was brought up, on the second cruise of 
the Expedition, in the sea west of Lofoten (Stat. 251), 
from a depth of 634 fathoms. A very young example, 
apparently belonging to the same species, I had previously 
taken off the coast of Finmark, at a depth of 150 — 200 
fathoms. The Station mentioned above being in the cold 
area, the species may no doubt be regarded as an Arctic 
form.
