1*9 



Beskrivelse. Legemet er (se Pl, XV. Fig. 5) noget 

 mere undersætsigt end hos foregaaende Art og har Ryggen 

 temmelig bred og hvælvet. 



Hovedet har de mellem begge Par Følere fremsky- 

 dende Sidelapper mindre fremspringende og jevnt tilrundede. 



De forreste Epimerer er. naar undtages Iste Par, der 

 som sædvanlig er rudimentært, meget store, mere end dob- 

 belt saa hoie som Kroppen og dækker hinanden delvis ind- 

 byrdes. 4de Par er at' elliptisk .Fonn og kjendeligt større 

 md de 2 foregaaende tilsammen samt bagtil stumpt til- 



llllldet. 



De 3 forreste Bagkropssegmenters Sideplader er meget 

 smaa og har det bagre Hjørne noget udtrukket, men i 

 Enden afrundet. 



Øinene er som hos foregaaende Art meget smaa, med 

 rødligt Pigment. 



Følerne er ualmindelig stærkt forlængede, næsten at' 

 hele Legemets Længde og indbyrdes omtrent ens udviklede. 

 Iste Pai- har Skaftets 2deJ Led noget hengere end Iste. 

 hvorimod 3die Led som sædvanlig er meget lidet. Svoben 

 er noget hengere end Skattet, meget tynd og delt i talrige 

 korte Led. 2det Par har Skaftets sidste Led storst og 

 Svoben vel ndviklet. omtrent af dettes Længde. 



Iste Fodpar synes i det nærmeste at ligne samme 

 hos foregaaende Art. 



2det Fodpar er særdeles kraftigt udviklet, med Haan- 

 den meget stor og udvidet mod Enden. Griberanden er 

 noget skråa og næsten lige samt grovt tandet i hele sin 

 Længde; nedentil begrændses den af et kort triangulært 

 Fremspring, der udgaar noget foran Midten af Haandens 

 Længde. 



De øvrige Fodpar ligner idethele samme hos foregaa- 

 ende Art. 



Det samme gjælder ogsaa Halefødderne og Haleved- 

 hænget. 



Farven er hvidagtig og gjennemsigtig, med kun yderst 

 sparsom Pigmentering. 



Længden af det undersøgte Exemplar er 7' altsaa 



betydelig mindre end af foregaaende Art. 



Forekomst. Et enkelt Exemplar af denne Art toges 

 under Expeditionens sidste Togt sammen med foregaaende 

 i Havet SV af Spitsbergen (Stat. 343) fra et Dyb af 743 

 Favne. 



Description. — The body is (see Pl. XV, fig. 5) a 

 trifle morr thickset than in tin' preceding species, with the 

 back rather broad and arcuate. 



The head has the lateral lobes — projecting hetween 

 both pairs of antenna' — less protruding, andevenlj rounded. 



The anterior epimera, saving the ist pair. which, as 

 nsual. occur rudimentary, are verylargt — more than twice 

 as high as the body — and pnrtially overlap each other. 

 The 4th pair are elliptic in form and appreciably larger 

 than the 2 preceding ones tåken .together, as also, hind- 

 wards. obtusely rounded. 



The lateral plates of the 3 anterior abdominal seg- 

 ments are very small, and have the posterior corner some- 

 what exserted, though rounded at the tip. 



The eyes, as in the preceding species, are exceedingly 

 small, aud furnished with a reddish pigment. 



The antennæ are remarkably elongated, -- attaining 

 well-nigh the total length of the body, and about equal in 

 development. The Ist pair have the 2nd joint of the 

 peduncle somewhat longer than the Ist. whereas the 3rd 

 joint occurs, as usual, very small. The flagellum is :i trifle 

 longer than the peduncle, exceedingly slender, and divided 

 into numerous short articulations. The 2nd pair have the 

 last joint of the peduncle largest, and the flagellum well 

 developed, about equal in length to the latter. 



The Ist pair of legs would appear in all essential 

 characters to resemble that pair in the preceding species. 



The 2nd pair of legs are most powerfully developed, 

 with the hand very large and dilated at the extremity. 

 The palmar margin is somewhat obhque, almost straight, 

 aud coarsely dentate throughout the whole of its length; 

 below, it is marked ofl' by a short triangular projection, 

 jutting out somewhat anteriorly to the longitudinal middle 

 of the haml. 



The remaining pairs ol' legs resemble upon the whole 

 the corresponding pairs in the preceding species. 



This applies also to the caudal stylets and the telson. 



The colour is whitish and translucent, with hut very 

 faint pigmentation. 



Length of the specimen examined 7 , )L .'"". and hence 

 considerablj less than that of the preceding species. 



Oceurrence. — A single specimen of this species 

 was tåken, along with the preceding, in the open sea 

 south-west of Spitzbergen 'Stat. 343), at a depth of 743 



fathonis.
