'/.i længere end Laarleddet og næsten 3 Gange saa langt 

 som det terminale Afsnit. Tarsalleddet (se Fig. 1 g) er af 

 smal lineær Form og ubetydeligt længere end Fodleddet. 

 Dette sidste er endnu noget smalere, ligeledes lineært og 

 i Inderkanten besat med meget smaa, næsten haarformige 

 Torner, hvoriblandt dog bemærkes omtrent i Midten nogle 

 faa noget stærkere saadanne. Endekloen er temmelig 

 stærkt forlænget, skjøndt adskilligt kortere end Fodlecfdet, 

 og sylformigt tilspidset i Enden. Bikløerne er forholdsvis 

 smaa, neppe 1 / i saa lange som Endekloen. 



Forekomst. Det ovenfor beskrevne Exemplar, tillige- 

 med et meget mindre Individ, blev tåget under Norden- 

 skjølds Expedition 1875 i det kariske Hav paa et Dyb at 

 40 — 50 Favne. De af Dr. Hansen undersøgte Exemplarer 

 var ligeledes fra det kariske Hav.

Artscharacter. Legemet spinkelt med vidt adskilte 

 forlængede Sidelortsatser. Hovedsegmentet saa langt som 

 de 2 følgende Segmenter tilsammen, Halsen tynd og for- 

 længet. Pandedelen kun lidet udvidet. Øieknuden stærkt 

 opbøiet, med Enden konisk tilspidset. Snabelen næsten 

 af Hovedsegmentets Længde. Saxlemmerne mindre kraf- 

 tige ; Haanden omtrent af Skaftets Længde, noget udvidet 

 paa Midten og besat med korte Haar; Fingrene næsten 

 af Palmens Længde, temmelig stærkt krummede i Enden. 

 Folerne med 2det Led betydelig kortere end 3die; sidste 

 Led næsten dobbelt saa langt som næstsidste og afsmal- 

 nende mod Enden; begge tilsammen omtrent af 3die Leds 

 Længde. De falske Fodder hos Hannen a / 3 længere end 

 Legemet, 4de og Ste Led omtrent af ens Længde, Ende- 

 delen kortere end 5te Led. Randtornerne smalt lancet- 

 formige med et Par stærkere Tænder nærmere Basis, det 

 ydre Parti fint saugtakket. Gangfodderne stærkt forlæn- 

 gede. omtrent 5 Gauge længere end Legemet og besatte 

 med korte og spredte Haar; 2det Lægled meget smalt, 

 mere end 1 / 3 længere end Laarleddet. men neppe mere 

 end dobbelt saa langt som det terminale Afsnit; Tarsal- 

 leddet forhenget, lineært; Fodleddet adskilligt kortere, 

 noget afsmalnende mod Enden, og bevæbnet i Inderkanten 

 med tynde, næsten børsteformige Torner; Endekloen sær- 

 deles lang. næsten af Fodltddets Længde, leformigt 

 krummet ved Basis og endende i en sylformig Spids;

joint is about ' j longer than the femoral one, and nearly 

 3 times as long as the terminal section. The tarsal joint 

 (see fig. 1 g) is narrow, linear in form, and hut very 

 little longer than the propodal joint. The latter joint is 

 still somewhat slenderer and also linear, and is beset on 

 the inner edge with exceedingly small, well-nigh capilliform 

 spines, among which a few somewhat stronger ones are 

 observed almost in the middle. The terminal claw is a good 

 deal produced, though considerably shorter than the pro- 

 podal joint, and is acuminated in the form of an awl at the 

 extremity. The auxiliary claws are comparatively small, 

 scarcely l ji of the length of the terminal claw. 



Occurrence. The above described specimen as well 

 as a much smaller individual, were tåken on Norden- 

 skjold's Expedition in 1875, in the Kara Sea, at a depth 

 of 40 — 50 fathoms. The specimens examined by Dr. Hansen 

 were also from the Kara Sea.

Speciflc Characters. Body slender. with widely separ- 

 ated elongated lateral processes. Cephalic segment as long 

 as the 2 succeeding ones tåken together. neck slim and 

 elongate, frontal part only slightly expanded. Oeuliferous 

 tubercle exceedingly elevated, with the extremity conically 

 acuminated. Proboscis well-nigh as long as the cephalic 

 segment. Chelifori not very powerful; hand about as long 

 as the scape, somewhat expanded in the middle, and beset 

 with short hairs; fingers nearly as long as the palm, a 

 good deal curved at the tip. Palpi with the 2nd joint 

 considerably shorter than the 3rd; last joint nearly twice 

 as long as the penultimate one and tapering towards the 

 extremity. and together about as long as the 3rd joint. 

 False legs in male -',., longer than the body, 4th and 5th 

 joints about eqnal in length, terminal part shorter than 5th 

 joint, marginal spines slender lanceolate, with a pair of 

 strongish teeth near the base, outer part finely serrate. Am- 

 bulatory legs greatly elongated, about 5 times longer than the 

 body, and beset with short and scattered hairs; 2nd tibial joint 

 verv slender. upwards of l / 3 longer than the femoral joint 

 but hardly more than twice as long as the terminal section ; 

 tarsal joint elongated, linear; propodal joint a good deal 

 shorter, tapering a little towards the end, and arm ed on the 

 inner edge with delicate, well-nigh setiform spines; terminal 

 elaw particularly long. almost as long as the propodal 

 joint, faleiformly arcuate at the base and terminating
