De 4 forreste Par Epimerer er vel udviklede, kjende- 
ligt hqiere end selve Kroppen, og tiltager noget i Storrelse 
bagtil. 3die Bagkropssegments Sideplader ender bagtil med 
et tydeligt, nresten retvinklet Hjorne. 
Af 0ine er paa de opbayarede Exemplarer intetsom- 
helst Spor at se. 
Folerne er forholdsvis usaedvanlig korte og robuste, 
paa langt nmr ikke opnaaende Legemets halve Lsengde, og 
er kun sparsomt besatte med ganske korte Bsrsteknipper 
i den bagre Kant, lste Par bar Skaftets 1 ste Led kortere 
end Hovedet, det fplgende betydclig laengere, sidste noget 
kortere end 2det. Svpben er lidt mere end halvt saa lang 
som Skaftet og sammensat af 7 Led. Bisvoben (se Fig 2 a) 
bestaar ogsaa her kun af 1 Led, men er dog mindre rudi- 
mentter end hos foregaaende Art og nsesten saa lang som 
Svpbens lste Led. 2det Par Fplere bar Svo'ben kortere 
end Skaftets sidste Led og bestaaende af 6 Led. 
De 2 forreste Fodpar (Fig. 2 b, c ) er af undersaetsig 
Bygning og som ssedvanlig noget ulige udviklede, idet 2det 
Par navnlig hos Hannen er betydelig stprre end lste. Haan- 
den er paa begge Par temmelig bred og sammentrykt, med 
tydeligt begrcendset Griberand; paa lste Par (Fig. 2 b) er 
den bagtil bevcebnet med 3 stmrke Torner; paa 2det Par 
(Fig. 3 c) ender den med et tydeligt vinkelformigt Frem- 
spring, der ligeledes fortil har 1 eller 2 smaa, Torner. 
\ 
De folgende Fodpar ligner i det mermeste samme hos 
foregaaende Art, dog med den Forskjel, at Hofteleddet paa 
de 3 bagerste Par er noget bredere. 
Halefpdderne er forholdsvis kortere end hos P. assi- 
milis; navnlig er dette tydeligt med sidste Par. 
Dyrets Farve er hvidagtig, uden tydelig Pigmentering. 
Laengden af de stprste erholdte Exemplarer overstiger 
ikke 6 1 /a mra . 
Forekomst. Yi har taget denne Art paa ikke mindre 
end 5 forskjellige Stationer, hvoraf ialfald de 4 tilhorer 
den kolde Area. Af disse ligger en (St. 31) udenfor Stor- 
eggen; de ovrige i Havet omkring Beeren Eiland og Spits- 
bergen: Dybden fra 146 til 767 Favne. Arten er herefter 
utvivlsomt at betragte som en aegte arktisk Form. 
The 4 anterior pairs of epimera are well developed, 
appreciably higher than the body, and increase a little in 
size posteriorly. The lateral plates of the 3rd abdominal 
segment terminate posteriorly with a distinct, almost rec- 
tangular corner. 
Of eyes in the specimens preserved no trace what- 
ever. 
The antennae are by comparison unusually short and 
robust, not attaining by far half the length of the body, 
and furnished, though sparingly, with very short bunches of 
bristles on the posterior margin. The 1st pair have the 1st 
joint of the peduncle shorter than the head, the succeeding one 
considerably longer, and the last somewhat shorter than the 
2nd. The flagellum is a little more than half as long as the 
peduncle, and composed of 7 articulations. The secondary 
flagellum in this form too, is uni-articulate, less rudimentary 
however than in the preceding species, and well-nigh as 
long as the 1st joint of the flagellum. The 2nd pair of 
antennae have the flagellum shorter than the last joint of 
the peduncle, and composed of 6 articulations. 
The 2 foremost pairs of legs (fig. 2 b, c) are thickset 
in structure, and as usual somewhat unequally developed, 
the 2nd pair, more particularly in the male, much larger 
than the 1st. The hand in both pairs is rather broad 
and compressed, with a distinctly defined palmar margin; 
on the 1st pair (fig. 2 b) it is armed posteriorly with 3 
powerful spines; on the 2nd (fig. 2 c) it terminates with 
a distinct angular projection, which, anteriorly, has likewise 
one or two small spines. 
The succeeding pairs of legs closely resemble those 
in the preceding species, but with this difference, that the 
basal joint on the 3 posterior pairs is somewhat broader. 
The caudal stylets are comparatively shorter than in 
P. assimilis; this is particularly appreciable as regards the 
first pair. 
Colour of animal whitish, without distinct pigmenta- 
tion. 
Length of the largest specimens taken not exceeding 
6 l l/ m . 
Occurrence. — We took this species at as many as 
5 different Stations, of which 4 at least belonged to the 
cold area. One of these (Stat. 31) lay off the Storeggen 
Bank, the others in the open sea round Beeren Eiland 
and Spitzbergen; depth ranging from 146 to 767 fathoms. 
Hence, the species must unquestionably be regarded as a 
true Arctic form.
