mindre Torner sees paa den &vre Flade. Dot fplgende 
Led er ikke ineget laengere og gaar ligeledes ved Enden 
paa den ydre Side ud i en staerk Torn. Do 2 folgende 
Led er tynde og forlsengede, nassten af sammo Lsengde 
indbyrdes, og dot forstc af dem liar ligeledes Enden ud- 
draget i en spids Torn. Svoben (se Fig. 26) er ganske 
kort, omtrent halvt saa lang som Skaftets sidste Led og 
bestaar kun af 3 simpelt cylindriske Led, uden Torner og 
kun forsynede mod nogle korte Haar. 
Munddelene viser ingen vaesentlig Forskjel fra samine 
bos den typiske Art. 
De 4 forstc Fodpar er ligeledes idethele af samme 
Udseende som hos hin Art, alone med den Forkjel, at der 
fra Enden af Basallodet paa do 3 bagerste af disse Par 
udgaar en skarp, bagudrettet Torn. 
De 3 bagre Fodpar aftager stserkt i Lsengde Uhgtil 
og er udnuerket derved, at deres Basallud i Midton af den 
bagre Kant bar et stserkt tandformigt Fremspring. 
Brystposen er som bos A. baffini sammensat af 3 
Par tydelige Plader. 
Bagkroppens Lemmer viser ingen vmsentlig Forskjel 
fra samme bos A. baffini. 
Farven var i levende Tilstand hvidagtig, med et svagt 
gronligt Skjfer, der vel for en Del skrev sig fra de i 
Brystposen indsluttede iEg. De lieste af Exemplarerne 
var imidlertid ved Optagelsen saa trnt besat med Smnds 
og forskjellige fremmede Partikler, der bavde faestet sig 
paa og mellem de talrige Pigge, at Legemets Form og 
Farve kun vanskeligt kunde erkjendes.

Forekomst og Udbredning. 3 Exeniplarer, alle Hun- 
ner, af denne distincte Form togos under Expeditionens 
lste Togt paa samme Sted (Stat. 18), livor foregaaende 
Art erboldtes. Under 2det Togt fandtes enkelte Exenipla- 
rer, ligeledes Hunner, af samme Art paa 2 andre Lokali- 
teter i Havet udenfor Helgoland og Lofoten (Stat. 124 og 
164), Dybden fra 350 til 457 Favne. Saintlige Stationer 
til borer den kolde Area. 
Artens for Tiden hekjendte Udbredning er saaledes 
Havet udenfor Norgus ydre Havbanker fra den 63de til 
den 69de Bredegrad. Samme Art er imidlertid, som jeg 
bar kunnet overbevisc mig om ved et mig af Norman vel- 
villigt meddelt Individ, ogsaa taget under Valorous’ Ex- 
pedition i de arktiske Farvande. 
thick, and at the end juts forth on the outer side as a 
strong spiniform projection ; 2 other smaller spines are 
seen on the upper surface. The succeeding joint is not 
much longer, and also juts forth at the end from the outer 
side as a strong spine. The 2 succeeding joints are slender 
and elongate, almost uniform in length, and the first has 
likewise the end produced as an acute spine. The flagel- 
lum (see fig. 26) is quite short, about half as long as the 
terminal joint of the peduncle, and consists of only 3 
simple cylindric joints, without spines, and furnished with 
merely a few short hairs. 
The oral appendages exhibit no essential difference 
from those in the typical species. 
The 4 first pairs of legs have likewise, on the whole, 
the same appearance as in that species, saving only that 
a sharp, posteriorly directed spine proceeds from the end 
of the basal joint on the 3 hindermost of those pairs. 
The 3 posterior pairs of legs diminish very much in 
length posteriorly, and are characterized by their basal 
joint having in the middle of the posterior margin a strong 
dentiform projection. 
The marsupium is composed, as in A. baffini, of 3 
pairs of distinctly developed plates. 
The abdominal limbs exhibit no essential difference 
from those in A. baffini. 
Tile colour, in a living state, was whitish, with a 
faint greenish tinge, in part no doubt arising from the 
eggs in the marsupium. Most of the specimens, however, 
were thickly incrusted with mud and other foreign substan- 
ces, adhering to and between the numerous spikes, thus 
rendering the form and colour of the body extremely diffi- 
cult to determine. 
The length of the largest examples did not reach 
more than 9""". 
Occurence and Distribution. — Three specimens of 
this distinct form, all of them females, were taken on the 
first cruise of the Expedition, in the same locality (Stat. 
18) where the preceding species occurred. On the second 
cruise, a few examples were obtained of the same species, 
likewise females, in two other localities, viz. off Helgelaud 
and Lofoten (Stats. 124 and 164); depth ranging from 350 
to 457 fathoms. The Stations lie all of them in the 
cold area. 
The distribution of the species, as at present known, 
extends accordingly throughout the ocean tract lying off 
the outer banks of the Norwegian coast, from the 63rd to 
the 69th parallel of latitude. The same form was, how- 
ever, as I have found, from the examination of a specimen 
kindly sent me by Mr. Norman, likewise taken in the 
waters of the Polar Sea, on the British Expedition with 
the “Valorous.”
