mere end halvt saa lang som Fodleddet, men meget stærk.
Bikloerne ere vel udviklede og omtrent af Endekloens halve
Længde.
I)e ydre Ægmasser var paa et af de undersøgte
Exemplarer (se Fig. 1) særdeles store og tilstede i dobbelt
Antal paa hver af de falske Fodder.
Forekomst. .Teg har af denne Art havt Anledning
til at undersøge 4 Exemplarer, indsamlede under
Nordenskjolds Expedition 1875 i det kariske Hav, Dybden 3—12
Favne, Sandbund.
Udbredning. Prof. Lilljeborg observerede denne Form
ved Sehuretskaja i Russisk Lapland. Af andre Forskere
er den ikke noteret. Dog maa Arten ifølge de her opførte
Findesteder utvivlsomt ansees for en ægte arktisk Form,
og dens specifiske Benævnelse ,.glaciale" maa derfor kaldes
vel begrundet.
The terminal claw is comparatively short, only little more
than half as long as the propodal joint, but exceedingly
powerful. The auxiliary claws are well developed, and are
about half the length of the terminal claw.
The outer egg-masses were in one of the specimens
examined (see fig. 1) remarkably large, and present in double
the usual number on each of the false legs.
Occurrence. Of this species I have had the opportunity
of examining 4 specimens collected on Nordenskjøld’s
Expedition, 1875. in the Kara Sea; depth from 3 to 12
fathoms, bottom sandy.
Distribution. Professor Lilljeborg observed this form
at Sehuretskaja in Bussian Lapland. By other naturalists
it is not recorded. The species must, however, to judge
from the localities here given, bo unquestionably regarded
as a true Arctic form, and, hence, its specific designation
„glaciale" must be said to be well founded.

Specific Characters. Body rather slim, with the lateral
processes well separated. Cephalic segment about as long
as the 3 succeeding segments taken together, neck slender
cylindrical, of moderate length, frontal part greatly expanded.
Oculiferous tubercle high, conically acuminated. Proboscis
comparatively large, almost the length of the cephalic
segment. Chelifori exceedingly powerful, hand the length
of scape, with the palm greatly prolonged, well-nigh cylindrie
and densely beset with short hairs, fingers scarcely more
than half as long and but very gently curved at the tips.
Palpi comparatively large, 2nd joint uncommonly short,
scarcely more than half as long as the 3rd one; last joint twice
as long as the penultimate one and tapering towards the
extremity. False legs in male excedingly elongated, more than
half as long again as the body, 5th joint somewhat longer
than the 4th. terminal part shorter than 5th joint, marginal
