148 til 743 F. Jeg liar endvidere liavt Anledning til at 
imders 0 ge flere Exemplarer fra det kariske Hav, tagne 
paa 3 forskjellige Punktcr under Nordenskjolds Expedition 
1875 og 1876; Dybden fra 40—70 F. Do af Dr. Hansen 
undersogte Exemplarer yar ligeledes fra det kariske Hav. 
TJdbredning. Ifolge skriftlig Meddelelse fra Di. 
Hansen, er Arten udbredt til det gronlandske Hav, idet 
den 1886 af Th. Holm er taget paa 72° 40' N. Br., 57° 
15' V. L.; Dybden 118 F. Den er saaledes utvivlsomt 
at betragte som en segte arktisk Form. Rigtignok ei 
den under Nordhavs-Expeditionen taget saa langt Syd som 
den 63de Bredegrad ; men det er at maerke, at den her 
kun forekom paa meget betydeligt Dyb i den kolde Area, 
hvor Forholdene tilnsermelsesvis svarer til dem paa grun- 
dere Vand i den arktiske Zone.

the others in the vicinity of Beeren Eiland and Spitzbergen ; 
depth from 148 to 743 fathoms. I have also had an op- 
portunity of examining divers specimens from the Kara 
Sea, taken in 3 different localities on Nordenskj old’s Expe- 
dition, 1875 and 1876; depth from 40 to 70 fathoms. The 
specimens examined by Dr. Hansen were likewise from the 
Kara Sea. 
Distribution. According to a written communication 
from Dr. Hansen, the species occurs as far north as the 
Greenland Sea, Th. Holm having taken it (1886) in lat. 
72° 40' N., long. 57° 15' W. ; depth 118 fathoms. The ani- 
mal must unquestionably, therefore, be regarded as a genuine 
Arctic form. It was taken, it is true, on the North- Atlantic 
Expedition as far south as the 63rd parallel of latitude; 
but it is to be remarked that it occurred there only at a 
very considerable depth, in the cold area, where the con- 
ditions agree approximately with those distinguishing shal- 
lower waters in the Arctic Zone.

Specific Characters. Body exceedingly slender, with 
thin and elongated limbs. Cephalic segment about as long 
as the 3 following segments taken together, neck very 
narrow, frontal part greatly expanded. Oculiferous tubercle 
somewhat elevated, and blunted at the extremity. Pro- 
boscis same length as the cephalic segment, narrow cvl- 
indric. Chelifori exceedingly slender, relatively shorter 
than in N. elegans, scape straight, with a few long setae 
on the upper edge, hand the length of scape, very narrow, 
fingers longer than the palm, both drawn out to an exceed- 
ingly thin and strongly incurvate point, teeth on the inner edge 
of the immobile finger long and thin, unequal in length. Palpi 
remarkably slender, 2nd joint almost twice as long as the. 3rd, 
last joint shorter and considerably more slender than the 
4th, both taken together longer than the 3rd. False legs in 
the male one-fourth longer than the body, 5th joint greatly 
elongated, marginal spines broad-lanceolate and regularly 
serrated on the edges. Ambulatory legs uncommonly slim 
and beset with scattered hairs, almost five times as long as 
the body, 2nd tibia! joint greatly elongated and remarkably 
thin, more than 4 times longer than the terminal section, 
propodal joint shorter than the tarsal joint, both thin and 
linear, with small capilliform spines on the edges, terminal 
claw half the length of the propodal joint, auxiliary claws 
uncommonly large, two-thirds of the length of the claw 
itself. Outer egg-masses small, but with very large ova.
