Dyrets Farve er hvidagtig og temmelig gjennemsigtig,
med kun sparsomt rødligt Pigment, der er afsat hist og
her i uregelmæssige Shatteringer.
Længden gaar op til 14""", og nærværende Art maa
saaledes betragtes som en ren Kjæmpe i Sammenligning
med de øvrige, fordetmeste pygmæiske Former, der
sammensætter den ber omhandlede Familie.
Forekomst og Udbredning. Vi har taget denne
anselige Art paa 2 vidt adskilte Localiteter, den ene (St. 31)
beliggende i Havet udedfor Storeggen, ilen anden (St. 343)
SV af Spitsbergen; Dybden fra 417 til 743 Favne. Begge
Stationer tilhører den kolde Area. Arten forekommer
imidlertid ogsaa ved vore nordlige Kyster. Fra Hammerfest
har jeg nemlig et Par vel udprægede Exemplarer, der vistnok
er adskilligt mindre, men torøvrigt i alt væsentligt stemmer
overens med de under Nordhavsexpeditionen tagne.
The ground-colour of the animal is whitish and
well-nigh translucent, with a reddish pigment sparingly disposed
here and there in irregular patches.
Tbe length reaches 14’"™. and the present species
must, therefore, be regarded as a veritable giant in
comparison with the other, as a rule pygmean, forms that
constitute the family treated of here.
Occurrence and Distribution. — This large-sized
species was taken in 2 widely distant localities, tbe one (Ståt. 31)
lying in the open sea off Storeggen, the other (Ståt. 343)
located south-west of Spitzbergen; depth from 417 to 743
fathoms. Both Stations belonged to the cold area. Tbe
species, however, also occurs off’ the northern shores of
Norway. From Hammerfest, I have in my possession a
few well-marked specimens, which are indeed a good deal
smaller, but for the rest closely agree in all essential
characteristics with those taken on the Norwegian North-Atlantic
Expedition.

Artscharacteristik. Legemet noget mere undersætsigt
end hos foregaaende Art. Hovedets Sidehjørner mindre
fremspringende. 4de Par Epimerer elliptiske, større end
de 2 foregaaende tilsammen. Øinene smaa, runde, med rødt
Pigment. Begge Par Følere stærkt forlængede, kun lidet
kortere end Legemet og indbyrdes omtrent ens udviklede;
2det Led paa lste Pars Skaft noget længere end lste Led.
2det Fodpar kraftigt udviklet, med Haanden meget stor og
opsvulmet, Griberanden noget skraa og næsten lige samt
grovt tandet, begrændset nedentil af en kort Fortsats. De
øvrige Lemmer omtrent som hos foregaaende Art. Farven
hvidagtig. Længden 7’//™.
Findested. Ståt. 343.
Bemærkninger. Fra foregaaende Art er denne let
kjendelig ved sin ringere Størrelse og de stærkt forlængede
samt ligeligt udviklede Folere. Fra il. longicornis Boeck,
der i Følernes Udseende nærmest stemmer med vor Art,
skiller den sig ved det stærkere forlængede 2det Led paa
lste Par Folere samt ved en forskjellig Form og
Bevæbning af 2det Fodpars Haand.

Specific Charachter. — Body somewhat more thickset
than in preceding species. Lateral corners of head less
projecting. Fourth pair of epimera elliptic, larger than
the 2 preceding ones taken together. Eves small, round,
with a red pigment. Both pairs of antennæ greatly
elongated, but very little shorter than the body, and well-nigh
uniform in development; 2nd joint of peduncle in 1st pair
somewhat longer than 1st joint. Second pair of legs
powerfully developed, with hand very large and tumid, palmar
margin somewat oblique and well-nigh straight, as also
coarsely dentate, marked off below by a short projection.
The other limbs about uniform with those in preceding
species. Colour whitish. Length 71
Locality. — Ståt. 343.
Remarks. — From tbe preceding species, tilis form
may be readily distinguished by its inferior size, as also by
the greatly elongated and equably developed antennæ. From
il. longicornis Boeck, which, in the appearance of the
antennæ, approximates closest the present species, it differs
by the greater elongation of the 2nd joint of the 1st pair
of antennæ, as also by the different form and armature of
the hand of the 2nd pair of legs.
