en for en Amphipode aldeles eolosal Størrelse. Vi liar
noteret den paa ikke mindre end 8 forskjellige Stationer
(St. 18, 33, 54. 124, 192, 251, 333, 312), alle tilhørende
dell kolde Area, Dybden fra 350 til 748 Favne.
Foruden i Nordhavet, hvor Arten forekommer fra den
63de til den 76de Bredegrad, er den som anført under den
Øster. Ungarske Nordpolexpedition observeret i Havet Øst
af Spitsbergen og nordlig til det nyopdagede Franz-Josephs
Land. Arten er saaledes utvivlsomt at betragte som en
ægte arktisk Fonn.

Artscharaeteristik. Legemet kort og undersætsigt,
med særdeles haarde Integuraenter, Hovedet stort og tykt
med et langt og tilspidset nedadboiet Pandehorn; imellem
dette og Hovedets Sider en dyb Indbugtning. Alle
Forkropssegmenter og de 3 forreste Bagkropssegmenter oventil
tydeligt kjolede. Kjolen paa de 4 bagre Forkropssegmenter
gaaende ud i enkle sammentrykte dorsale Fortsatser. paa
de forreste Bagkropssegmenter i 2 paa hinanden følgende
Spidser. De 3 bagre Segmenter hvert oventil i Midten
af den bagre Rand bevæbnet med et tandformigt opadrettet
Fremspring; 4de Segment desuden med et lignende i Midten
af Rygsiden. De forreste Epimerer smaa og smale; 4de
Par mindre end de foregaaende og skjævt afkuttet i Enden;
5te og 6te Par med den bagre Lap forlænget nedad. 3die
Bagkropssegments Sideplader bagtil i Midten noget
fremspringende og grovt saugtakkede, de nedre Hjørner skarpt
tilspidsede. Ingen Øine. Folerne tynde, af den for Slægten
characteristiske Bygning. De 4 forreste Fodpar meget smaa
og svage; de 3 bagerste derimod temmelig robuste, med
pladeformigt udvidet og bagtil saugtakket Hofteled.
Halevedhænget særdeles stort, triangulært, pladeformigt, med
en meget sinai median Fissur. der naar ud over Midten.
Farven ensformig gulgraa. Længden 8’/s™.

Amphipod a truly colossal size. We had the species from
not less than 8 different Stations (Stats. 18, 33. 54. 124.
192, 251, 333, 312), all in the cold area; depth ranging
from 350 to 748 fathoms.
Exclusive of the North-Atlantic, where the species ranges
from the 63rd to the 76th parallel of latitude, this form,
as seen from the work cited above, was observed on the
Austrio-Hungarian North Pole Expedition in the sea east
of Spitzbergen, and as far north as the recently discovered
Franz-Josephs Land. Hence the species must
unquestionably be regarded as a true Arctic form.

Specific Character. — Body short and thickset, with
exceedingly hard integuments. Head large and thick, with
long and acute, downward-bent rostrum; between the latter
and sides of head a deep sinus. All thoracic segments
and the 3 anterior abdominal segments distinctly carinated
above; keel on the 4 posterior thoracic segments jutting
out as simple, compressed, dorsal projections, on the 3
anterior abdominal segments, as 2 successive points. Each
of the 3 posterior segments armed above, in the middle
of the posterior margin, with a dentiform, upward-turning
projection: 4th segment furnished besides with a similar
projection, springing from the middle of the dorsal surface.
The foremost epimera small and slender; 4th pair smaller
than preceding, and obtusely truncate at extremity; 5th
and 6th pairs with posterior lobe prolonged downwards.
Lateral plates of 3rd abdominal segment somewhat
projecting in the middle posteriorly, and coarsely serrate.
No eyes. Antennæ slender, exhibiting the structure
characteristic of the genus. The 4 anterior pairs of legs
very small and feeble; the 3 posterior, on the other hand,
somewhat robust, with basal joint lamelliform-dilated and
serrate posteriorly. Telson exceedingly large, triangular,
lamelliform, with a very small median fissure, extending
beyond the middle. Colour a uniform yellowish - grey.
