Tarsalleddet (se Fig. 2 k) er smalt cylindriskt, eller 
ganske svagt udvidet mod Enden, og omtrent 3 Gange lsen- 
gere end bredt. Fodleddet er stserkt forhengct, over dob- 
belt saa langt som Tarsalleddet, noget opsvulmet i sit basale 
Parti, og langs hele lnderkanten forsynet med en tret og 
regelmsessig Rad af tynde, ens udviklede Torner. Ende- 
kloen er af ganske ualmindelig Lsengde, neppe kortere end 
Fodleddet, og viser ved Basis en stasrk, ligesom knseformig 
Boining; dens ydre Parti er nmsten lige og af smal ledan- 
net Form, med den indre Kant tilskjferpet. Bikloerne er 
saa yderst smaa og rudimentmre, at de meget let vil kunne 
oversees. 
De ydre JEgmasser (se Fig. 2 b) er af kugledannct 
Form og indeholder kun et ringe Antal af ualmindelig 
store JEg. Ofte Andes AEgmasserne i dobbelt Antal paa 
hver af de falske Fodder. 
Forekomst. Af naervierende. characteristiske Art blev 
talrige Exemplarer indsamlede under Nordhavs-Expeditionen 
paa forskjellige Punkter af det af os undersogte Havst.rog. 
Den er saaledes noteret fra ikke mindre end 9 forskjellige 
Stationer, tildels temmelig vidt adskilte fra hinanden. Af 
disse ligger en (Stat. 18) i Ha vet mellem Norge og Fser- 
eerne, 2 (Stat. 124, 137) lmngere Nord, udenfor Nordlands- 
kysten, 2 (Stat. 190, 192) N af Vesteraalen, 1 (Stat. 262) 
O af Varda, 1 (Stat. 286) SV af Beeren Eiland, og ende- 
lig 2 (Stat. 343, 362) udenfor Syd- og Nordvestkysten af 
Spitsbergen; Dybden fra 148 til 870 Favne. Alle Sta- 
tioner, alene med Undtagelse af St. 262, tilharer den kolde 
Area. Ogsaa fra det kariske Hav bar jeg liavt adskillige 
Exemplarer til Undersagelse, indsamlede under Norden- 
skjolds Expedition. Exemplarerne forekom her, som smd- 
vanlig, paa betydelig ringere Dyb end i Nordhavet. 
Udbredning. Arten anfares af Hoek fra Havet oin 
Fasraerne („Knight Errant 11 Expedition) og af Hansen fra 
det kariske Hav. Derimod er den hverken kjendt fra 
Gronland eller Nordamerika’s Ostkyst. At Arten imidler- 
tid er en segte arktisk Form, er utvivlsomt. 
Gen. 10. Boreonymphon, G. 0. Sars, 1888. 
Slsegtscharacter. Legemet tykt og robust, med tset 
sammentrsengte Sidefortsatser. Hovedsegmentet af betyde- 
lig Storrelse, med kort Hals og stserkt fortykket Pandedel. 
Gieknuden rudimentser, uden Synselementer. Snabelen 
konisk tillabende. Saxlemmerne kraftigt udviklede, Haan- 
den med kort Palm og stserkt forltengede glatte, mesten halv- 
cirkelformigt baiede Fingre. Folerne omtrent som hos Nym- 
phon. De falske Fodder lidet forskjellige hos de 2 Kjoii, 
hos Hannen tint besatte med pigformige, omboiede Borster; 
Randtornerne simple, uden Saugtakker, Endekloen glat. 
The tarsal joint (see fig. 2 k) is narrow cylindric, 
or quite faintly expanded towards the extremity, and is 
about 3 times as long as it is broad. The propodal joint 
is greatly elongated, more than twice as long as the tarsal 
joint, somewhat tumefied in the basal portion, and is fur- 
nished along the whole of the inner ‘margin with a close 
and regular series of thin, uniformly developed spines. 
The terminal claw is of quite unusual length, scarcely 
shorter than the propodal joint, and at the base exhibits 
a strong, almost geniculate bend; its outer portion is almost 
straight, and of narrow falciform shape with the inner 
margin sharpened. The auxiliary claws are so extremely 
minute and rudimentary that they may easily escape ob- 
j servation. 
The external egg-masses (see fig. 2 b) are globular 
in form, and contain only a small number of unusually 
large ova. The egg-masses are frequently found in double 
number on each of the false legs. 
Occurrence. Numerous specimens of this characteristic 
species were collected during the North Atlantic Expedition, 
at different points of the ocean tracts investigated. It is thus 
remarked at no less than 9 different stations, to some 
extent greatly separated from each other. Of these, one 
(Stat. 18) is situated in the ocean between Norway and 
the Faroe Islands; 2 (Stat. 124, 137) farther north, off 
the coast of Nordland; 2 (Stat. 190, 192) north of Vester- 
aalen; 1 (Stat. 262) east of Vard5; 1 (Stat. 286) south- 
west of Beeren Island; and, finally, 2 (Stat. 343, 362) off 
■ the south and north-west coasts of Spitzbergen ; depth 
148 to 870 fathoms. All the stations, with the exception 
of St. 262 only, pertain to the cold area. From the Kara 
Sea I have also had several specimens for investigation, 
collected by Nordonskj old’s Expedition. These specimens, 
were obtained, as usual, at considerably less depth than 
in the North Atlantic Ocean. 
Distribution. The species is remarked by Hoek 
from the seas around the Faroe Islands („Knight Errant 11 
Expedition), and by Hansen from the Kara Sea. On the 
other hand, it is unknown from either Greenland or the 
east coast of North America. It is, however, indubitable, 
that the species is a genuine Arctic form.

Generic Characters. Body thick and robust, with 
.closely crowded lateral processes. Cephalic segment of 
considerable size, with short neck and greatjy tumefied 
frontal part. Ocular tubercle rudimentary, without visual 
elements. Proboscis running out in coniform. Chelifori 
powerfully developed ; the hand with short palm and greatly 
elongated, smooth fingers, almost semi-circularly bent. 
Palpi nearly the same as in Nymphon. False legs some- 
what different in the 2 sexes; in the male closely beset 
with spiniform, recurvate bristles; marginal spines plain
