en for en Amphipode aldeles colosal Storrelse. Vi har 
noteret den paa ikke inindre end 8 forskjellige Stationer 
(St. 18, 33, 54, 124, 192, 251, 333, 312), alle tilharende 
den kolde Area, Dybden fra 350 til 748 Favne.

63de til den 7(5de Bredegrad, or den som an fort under den 
0ster. Ungarske Nordpolexpedition observeret i Havet 0st 
af Spitsbergen og nordlig til det nyopdagede Franz-Josephs 
Land. Arten er saaledes ntvivlsomt at betragte som en 
asgte arktisk Form.

Artseharacteristik. Legemet kort og undersfetsigt, 
med s;erd eles haarde Integuraenter, Hovedet stort og tykt 
tiled et Iangt og tilspidset nedadboiet Pandehorn; imellem 
dette og Hovedets Sider en dyb Indbugtning. Alle For- 
kropssegmenter 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 liinanden folgende 
Spidser. De 3 bagre Segmenter livert oventil i Midten 
af den bagre Rand bevaffmet mod et tandformigt opadrettet 
Fremspring; 4de Segment desuden mod et ligne.nde i Midten 
af Rygsiden. De forreste Epimerer smaa og smale; 4de 
Par mindre end de foregaaende og skjcevt afkuttet i Enden ; 
5te og 6te Par med den bagre Lap forkenget nedad. 3 die

characteristiske Bygning. De 4 forreste Fodpar meget smaa 
og svage; de 3 bagerste derimod teinmelig robuste, med 
pladeformigt udvidet og bagtil saugtakket Hofteled. Hale-

Findested. Stat. 124. 
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 tin 1 cold area; depth ranging 
from 350 to 748 fathoms. 
Exclusive of the North-Atlantie, 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-H u ngarian North Pole Expedition in the sea east 
of Spitzbergen, and as far north as the recently discovered 
Franz-Josephs Land. Hence the species must unques- 
tionably 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 pro- 
jecting in the middle posteriorly, and coarsely serrate. 
No eyes. Antennse slender, exhibiting the structure char- 
acteristic 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 lamellifonn-dilated and 
serrate posteriorly. Telson exceedingly large, triangular? 
lamelliform, with a very small median fissure, extending 
beyond the middle. Colour a uniform yellowish -grey-
