De falske Fodder hos Hannen (se Fig. 3 a) er naesten 
i/ 3 lamgere end Legemet og liar som ssedvanlig 5te Led 
lamgst, men kjendelig kortere end Endedelen. Randtor- 
nerne (Fig. 3 f) er af lancetdannet Form og bar i det 
basale Parti 2 Par staerke Sidetsender, medens Yderdelen 
er regelmaessigt saugtakket, med 6 Takker til liver Side. 
Gangfodderne (se Fig. 3) er mindre iorlaengede end 
hos de fleste evrige Arter, idet de neppe er mere end 3 / 3 
Gang laengere end Legemet. De er heller ikke saa staeikt 
afsmalnende mod Enden og viser i sin hole Lamgde en 
temmelig tact Besaetning af korte og fine Haar. Ai Led- 
dene er vistnok ogsaa her 2det Ltegled det lsengste, men 
er dog neppe dobbelt saa langt som det terminale Atsnit 
og kun lidet lamgere end Laarleddet. Tarsalleddet ei loi- 
holdsvis kort, hvorimod Fodleddet er temmelig iorlamget, 
noget krummet, og meget smalt, uden ioinefaldende Torner 
i Inderkanten. Endekloen er ualmiudelig kort, kun lidet 
mere end >/s saa lang som Fodleddet, men temmelig kraftig. 
Bikloerne er vel udviklede og naesten halvt saa lange som 
selve Kloen. 
Ingen af de undersogte Exemplarer havde ydre iEg- 
masser, om de end havde Udseendet af at vaere fuldt ud- 
viklede. 
Forekomst. Et Par Exemplarer af denne Art fandtes 
i den mig til Undorsogelse overladte Sanding af Pycnogoni- 
der, indsamlede under Nordenskjplds Expedition 1875 og 
76. Do var begge fra Straedet Matotschinscharr ; Dybden 
2—15 F. 
The false legs in the male (see fig. 3 a) are almost 
one-third longer than the body, with the 5th joint, as 
usual, longest, but appreciably shorter than the terminal 
part. The marginal spines (fig. 3 f) are lanceolate in 
form, and have in the basal part 2 pairs of strong latei al 
teeth, while the outer part is regularly serrate, with 6 
denticles on either side. 
The ambulatory legs (see fig. 3) are less elongated 
than in most of the other species, being hardly upwards 
of 3 1 / 3 times longer than the body. Nor do they tapei so 
rapidly towards the extremity, and they exhibit throughout 
their entire length a rather dense covering of short and 
delicate hairs. Of the joints, the 2nd tibial joint is here, 
also, certainly the longest, though hardly twice as long 
as the terminal section and but little longer than the 
femoral joint. The tarsal joint is relatively short, whereas 
the propodal joint is rather elongated, somewhat curved, 
and very narrow, without prominent spines on the inner 
edge. The terminal claw is uncommonly short, only little 
more than one-third as long as the propodal joint, but 
rather powerful. The auxiliary claws are well developed 
and almost half as long as the claw itself. 
None of the specimens examined had outer egg- 
masses. even though they were fully developed, to judge 
from their appearance. 
Occurence. Two examples of this species were found 
among the Pycnogonids collected on Nordenskjold’s Expedi- 
tion, 1875 and 76, and sent me for examination. They were 
both from the Matotschinsharr Strait; depth 2 — 15 fathoms.

Arts character. Legemet spinklere end hos foregaaende 
Art. Hovedsegmentet omtrent saa langt som de 3 folgende 
Segmenter tilsammen, med tydelig, skjondt ikke meget ior- 
henget Hals, og kun meget lidet udvidet Pandedel. 0ie- 
knuden temmelig lav, afkuttet i Enden og forsynet med 
fremspringende Sidehjorner. Snabelen kortere end Hoved- 
segmentet, eylindrisk. Saxleminerne smaa og svage, Haan- 
deu betydelig kortere end Skaftet, forholdsvis sinal og tset 
haaret ; Fingrene af Palmens Lamgde, med starlet indbpiede 
Spidser. Folerne forholdsvis korte og tret haarede, idet

Specific Characters. Body more slender than in 
the preceding species. Cephalic segment about as long as 
the 3 following segments taken together, with the neck dis- 
tinct, though not very elongated, and the frontal part but very 
little expanded. Oculiferous tubercle rather low, truncated 
at the extremity, and furnished with projecting lateral corners. 
Proboscis shorter than the cephalic segment, cyhndiic. 
Chelifori small and feeble, hand considerably shorter than 
the scape, comparatively narrow, and densely hairy ; the fin- 
gers same length as palm, with strongly incurvated points. 
The palpi relatively short and densely hirsute, 2nd and 
3rd joints of equal size; the last but little longer than the 
penultimate one, and both taken together equal i in length to 
the 3rd. False legs but little longer than the body, marg- 
inal spines very slender, dagger-shaped, shortly-serrated on 
the edges. Ambulatory legs beset with scattered delicate,, 
hairs, rather elongate, a trifle more than 4 tunes as long
