en for en Amphipode aldeles colosal Størrelse. Vi har 

 noterel den paa ikke mindre end 8 forskjellige Stationer 

 (St. is. 33, .",4. 124. 192, 251, 333, 312), alle tilhørende 

 den kolde Area. Dybden fra 350 til 748 Favne. 



Poruden i Nordhavet, hvor Arten forekommer fra den 

 63de til tien 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 

 æarte arktisk Form.

Artseharacteristik. Legemet kort og undersætsigt, 

 med særdeles haarde [nteguraenter, Hovedet stort og tykt 

 med et langi og tilspidset nedadbøiet Pandehorn; imellem 

 dette og Hovedets Sider en dyb Indbugtning. Alle For- 

 kropssegmenter og de 3 forreste Bagkropssegmenter oventil 

 tydeligt kjølede, Kjolen paa de 4 bagre Porkropssegmenter 

 gaaende nd i enkle sammentrykte dorsale Portsatser, paa 

 de tniieste 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 frem- 

 springende og grovt saugtakkede, de nedre Hjørner skarpt 

 tilspidsede. Ingen Øine. Følerne tynde, af den for Slægten 

 characteristiske Bygning. De 4 forreste Podpar meget smaa 

 og svage; de 3 bagerste derimod temmelig robuste, med 

 pladeformigt udvidet og bagtil saugtakket Hofteled. Hale- 

 vedhænget særdeles stort, triangulært, pladeformigt, med 

 en meget smal median Pissur, der naar nd over Midten. 

 Farven ensformig gulgraa. Længden s' /"". 



Findested. Stat. 124. 



Amphipod a truly colossal size. We bad the species trom 

 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 parabel 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 unques- 

 tionablv be reearded as a true Arctic form.

Specific Character. — Body short and thickset, with 

 exceedingly hard integuments. Head large and thick, with 

 lung and aeute. 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. Antennæ 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 lamelliform-dilated and
