De 2 f0lgende Fodpar (se Fig. 4) er overordentlig 
tynde, nsesten traadformige, med korte Borster og forlmnget 
Endeklo. 
De 3 bagre Par tiltager successivt i Laengde bagtil 
og liar Hofteleddet noget udvidet ved Basis og i det nedre 
bagre Hjorne udtrukket til en skarp Spids. 
De 2 forreste Par Halefodder liar den ydre Gren be- 
tydelig kortere end den indre. Sidste Par (se Fig. 4 f) 
er kraftigt udviklet, med temnielig tyk Stamme og stserkt 
forlmngede, lancetformige Grene, der mesten er indbyrdes 
af ens Lsengde. 
Halevedluenget {ibid.) er aflangt triangukert og raekker 
ud over Stammen paa sidste Par Halefodder. Spidsen er 
delt i 3 smaa Tsender, hvoraf den midterste er lsengst. 
Farven er hvidagtig, gjennemsigtig; kun hist og her 
bemserkes hos friske Exemplarer et rodligt Pigment, der 
tildels danner utydelige Tvserbaand. 
Lsengden gaar op til 24™ m , og nservserende Art er 
saaledes betydelig storre end nogen af de tidligere beskrevne. 
Forekomst. Et enkelt Exemplar af denne Art toges 
under Expeditionens lste Togt i Havet udenfor vor Yest- 
kyst (Stat. 33) fra et Dyb af 525 Favne. Under 2det 
Togt erholdtes talrige Exemplarer af samme Art paa et 
nordligere Punkt i Havet udenfor Helgelandskysten (Stat. 
124), Dybden 350 Favne. Begge disse Stationer tilliorer 
den kolde Area, og Arten maa derlbr utvivlsomt ansees for 
en arktisk Form.

Jeg giver her en forbedret Figur af denne characteri- 
stiske af Heller paa ovenantorte Sted beskrevne Form. I 
levende Tilstand er Legemet af bleg gulagtig Farve, med 
Munddelene og Storsteparten af Lemmerne carminrode. 0i- 
nenes Pigment er meget lyst, nsesten lividt. 
De af os indsamlede Exemplarer er betydelig storre 
end de af Heller undersogte, idet Lamgden gaar op til 
52"””, en for en Amphipode colossal Storrelse. 
The 2 succeeding pairs of legs (see fig. 4) are re- 
markably slender, almost filiform, with short bristles and 
elongate terminal claw. 
The 3 posterior pairs of legs increase successively in 
length from before to behind, and have the basal joint 
somewhat dilated at the origin, as also produced at the 
lower posterior corner to a sharp point. 
The 2 anterior pairs of caudal stylets have the outer 
branch considerably shorter than the inner. The last pair 
(see fig. 4 f) arc powerfully developed, with a thickish 
stem and very elongate, lanceolate branches, almost uni- 
form in length. 
The telson (ibid.) is oblongo-triangular, and reaches 
beyond the stem of the last pair of caudal stylets. The 
point is divided into 3 small teeth, the median being the 
largest. 
Colour whitish, translucent; here and there only, in 
recently taken specimens, can be detected a reddish pig- 
ment, forming a few indistinct transverse bands. 
Length 24”™; the present species is therefore consider- 
ably larger than any of those previously described. 
Occurrence. — One individual only of this species was 
taken, on the first cruise of the Expedition, off the west- 
coast of Norway (Stat. 33), at a depth of 525 fathoms. 
On the second cruise, numerous examples were obtained, 
in a more northerly locality, viz. off the coast of Helge- 
land (Stat. 124), depth 350 fathoms. Both of these Sta- 
tions were in the cold area, and hence the species may 
unquestionably be considered an Arctic form.

I annex here an improved representation of this char- 
acteristic form, described in the above-cited Memoir by 
Heller. When living, the animal has the body of a pale, 
yellowish colour, tin* oral appendages and most of the 
limbs being of a rich carmine. The ocular pigment ex- 
ceedingly light, well-nigh colourless. 
The specimens collected on the Norwegian Expedition 
are considerably larger than any of those examined by 
Heller, their total length reaching 52’™’ — a truly colossal 
size for an Amphipod.
