mere end halvt saa lang som Fodleddet, men meget stork. 
Bikloerne ere vel udviklede og omtrent af Endekloens halve 
Lsengde. 
De ydre iEgmasser var paa et af de unders0gte 
Exemplarer (se Fig. 1) sserdeles store og tilstede i dobbelt 
Antal paa liver af de falske Fodder. 
Forekomst. Jeg liar af denne Art havt Auledning 
til at underspge 4 Exemplarer, indsamlede under Norden- 
skjolds Expedition 1875 i det kariske Hav, Dybden 3—12 
Favne, Sandbund. 
Udbredning. Prof. Lilljeborg observerede denne F orm 
ved Scburetskaja i Russisk Lapland. Af andre Forskere 
er den ikke noteret. Dog maa Arten if'plge de ber opforte 
Findesteder utvivlsomt ansees for en rngte arktisk Form, 
og dens specifiske Benaevnelse ,,glaciale“ maa derfor kaldes 
vel begrundet.

Arts character. Legemet temmelig spinkelt, med hide- 
fortsatserne vel adskilte. Hovedsegmentet omtrent saa langt 
som de 3 ftflgende Segmenter tilsammen, Halsen smalt cy- 
lindrisk, af middelmaadig Lsengde, Pandedelen storkt ud- 
videt. 0ieknuden hoi. konisk tilspidset. Snabelen forholds- 
vis stor, naesten af Hovedsegmentets Lamgde. Saxlemmerne 
saerdeles kraftige, Haanden af Skaftets Lamgde med Palmen 
storkt forlsenget, nresteu cylindrisk og tot besat med korte 
Haar, Fingrene neppe mere end halvt saa lange og kun 
meget svagt krummede i Spidsen. Fplerne forholdsvis store, 
2det Led ualmindelig kort, neppe mere end halvt saa langt 
som 3die , sidste Led dobbelt saa langt som nsestsidste og 
afsmalnentle mod Enden. De falske Fpdder lios Hannen 
storkt forlsengede, mere end V* Gang til saa lange, som 
Legemet, 5te Led noget lsengere end 4de, Endedelen kor- 
tere end 5te Led, Randtornerne smalt lancetformige, med

The terminal claw is comparatively short, only little more 
than half as long as the propodal joint, but exceediugly 
powerful. The auxiliary claws are well developed, and are 
about half the length of the terminal clan. 
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 Nordenskjqld s Ex- 
pedition, 1875, in the Kara Sea; depth from 3 to 12 
fathoms, bottom sandy. 
Distribution. Professor Lilljeborg observed this form 
at Scburetskaja in Russian Lapland. By other naturalists 
it is not recorded. The species must, however, to judge 
from the localities here given, be 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. Ohelifori exceedingly powerful, hand the length 
of'scape, with the palm greatly prolonged, well-nigh cylindric 
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, scar- 
cely 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
