.■il' Bythocaris leucopis, samt 1 at' Pseudomysis abyssi, begge 

 Artor beskrevne i 1880 af Gr. O. Sars fva Nordhavs-Expedi- 

 tionens Indsamlinger. men ingeD af dem tidligere fundne 

 i en saa betydelig Dybde. Endelig fandtes et Individ af en 

 eiidnu ubestemt Hyperide. der saudsynligvis er ubeskreven. 



Udbredelse. Det eneste liidtil erholdte Exemplar 

 af denne mærkelige Art havde en Længde af omtrent l /a 

 Meter, og optoges. som ovenfor nævnt. fra det iskolde Vand 

 paa næsten 1300 Favnes Dyb midt ude paa Havet, den 

 l(3de Juli 1878. omtrent lige langt fra Spitsbergen. Jan

Diagn. Legemets Høj de nogei mindre, end Hovedlæng- 

 den, der indéholdes 4 — 4 1 ,-, Gange i Totallængden. Over- 

 kjæven gaar tilbage forbi Ojet, og ender triangulært afskaa- 

 ret ved Bonden of Praeoperculmu. Dorsalen ligger over 

 Mellemrummet méllem Ventrålerne og Analen. Øjet overor- 

 dentlig stort, indéholdes ikke fuldt 3 Gange, i Hovedlængden, 

 og er kon lidet mindre, end Hovedets postorbitale Del. 3 

 Skjælrækker ovenfor, 4 nedenfor Sidelinien. Skjællene glatte; 

 Sideliniens Skjæl større, end de øvrige. 21 — S3 Par Pletter 

 langs Buglinien (5 méllem St minn og Ventrålerne; 3 — 

 4 méllem Ventrålerne og Andlen; 7—8 langs Analen, 6 

 méllem Analen og Caudålen). Farven grønlig-brun oventil, 

 paa Midten gulagtig sølvglindsende , paa Bugen mørkere

and 1 of Pseudomysis abyssi, both species described (1880) 

 by Ci. O. Sars from specimens collected on the North At- 

 lantic Expedition, but not previously met with at so great 

 a depth; finally, an example of a Hyperid. as yet undeterm- 

 ined, and probably undescribed. 



Distribution. — The only example of this singular 

 species yet obtained measured in length one-third of a 

 metre, and. as previously mentioned, was taken in the 

 frigid area at a depth of nearly 1300 fathoms, in mid-ocean, 

 the locality being about equidistant from Spitzbergen, .Tan 

 Mayen, and Finmark. July Kith 1878.

Diagnosis. — Depth of the bodg a 'trifle less than the 

 length of the head, which is to total length as 1 to 4 — /',_■. 

 The ma. ciliary e.i tending backimrtls past the eye, and term- 

 inating in a triangular dilatation at the margin of the pre- 

 operculum. Dorsal fin placed above the space between 

 the centrals and the anal. Byes remarkably large: their 

 longitudinal diameter being to the length of the head very 

 nearly as 1 to 3. and a trifle less than the postqrbital region 

 of the head. Above the lateral line 3 rows of scales, below 

 4. Scales smooth : those on the lateral line larger than 

 the rest. Along the central line 21 — 23 pairs of spots (be- 

 tween the throat and the centrals ~> ; between the ventrals and 

 the anal 3 or 4: along the anal 7 — 8; between the anal 

 and the caudal 6). Colour (dioce a greenish-brown; in the 

 medial region yellowish, with a silvery lustre; on the abdo- 

 men, a dark dice green.
