og noget kruramet ; det er langs den ydre Kant og ved En- 
den besat med korte Borster og liar i Tnderkanten 4 standee 
Torner, fmstede til saerskilte Afsatser. Endekloen er neppe 
halvt saa lang som Fodleddet, men meget kraftig og stserkt 
cliitiniseret. Bikloerne er vel udviklede og omtrent halvt 
saa lange som Endekloen. 
Dyrets Farve er i levende Tilstand hvidagtig, halvt 
gjennemsigtigt. med et mere eller mindre tydeligt udprseget, 
vakkert violet Pigment, der baade er afsat paa selve Krop- 
pen og paa Leminerne, hvor det danner tydeligc Tvser- 
baand. 
Forekomst. Jog bar lain taget denne lille Art ved 
vor Sydkyst (Risper, Arendal), hvor den forekom enkeltvis 
paa ganske grundtVand mellem Alger. Paa vort Universi- 
tets Museum findes ogsaa nogle Exemplarer af denne Art 
fra vor Vestkyst, indsamlede af min Fader, men bestemte 
som N. brevitarse , Kroyer. 
Udbredning. Arten er utvivlsomt at betragte som 
en mere sydlig Form. Foruden ved Norge er den nemlig 
noteret fra de britiske 0er (Leach, Johnston), Danmark 
(Hansen), Holland og Nordkysten af Frankrige (Hoek). 
Derimod er den ukjendt i de arktiske Have.

strakt, med vidt adskilte forlmngede Sidefortsatser, enhver 
ved Enden oventil forsynet med 2 stive divergerende Bpr- 
ster. Hovedsegmentet omtrent saa langt som de 2 folgende 
Segmenter tilsammen, med stserkt forkenget og smal Hals; 
Pandedelen forholdsvis kun lidet udvidet. 0ieknuden stserkt 
ophoiet, konisk tilspidset, hoiere end bred. Snabelen neppe 
mere end halvt saa lang som Hovedsegmentet. Saxlem- 
merne svagere end hos foregaaende Art, Haanden kortcre 
end Skaftet, t;et haaret, Fingrene kortere end Palmen. om- 
trent som hos N. grucile. Folerne spinkle, 2det og 3die 
Led omtrent af ens Lsengde, sidste, Led dobbelt saa langt 
som nsestsidste. De falske Fodder hos Hannen lsengere 
end Legemet; 4de og 5te Led sserdeles stserkt forkengede 
og tynde; Endepartiet neppe kengere end 5te Led, med 
talrige Randtorner, de sidste af en lignende Bygning som 
hos N. gracile. (xangfodderne saerdeles spinkle, over 3 
Grange kengere end Legemet, og besatte med spredte, stserkt 
chitiniserede Borster ; Laarleddet omtrent saa langt som 
propodal joint is more than twice as long as the tarsal joint 
and somewhat curved; it is beset, along the outer edge 
and at the end with short bristles, and has on the inner edge 
4 strong spines, affixed to separate ledges. The terminal 
claw is hardly half as long as the propodal joint, but very 
powerful and highly chitinised. The auxiliary claws are 
well developed and about half as long as the terminal 
claw. 
The colour of the animal, is in the living state, whitish, 
semi-transparent, with a beautiful, more or less distinct, 
beautiful, violet pigment, deposited both on the trunk itself 
and on the limbs, where it forms well defined transverse 
bands. 
Occurrence. This diminutive species I have taken 
exclusively on the south coast of Norway (Riscfer. Arendal), 
where it is sparingly met with in very shallow water be- 
tween alum. In our University Museum there are a few 
specimens of this form from the west coast of the country 
collected by my late father, but determined as N. brevitarse, 
Kroyer. 
Distribution. The species must unquestionably be 
regarded as a more southern form. Besides Norway, it is 
recorded from the British Islands (Leach, Johnston), Den- 
mark (Hansen), Holland and the north coast of France 
(Hock). On the other hand it is quite unknown in the 
Arctic Seas.

Specific Character. Body excedingly slender and 
elongate, with widely separated, prolonged lateral processes, 
each at the extremity above provided with 2 stiff diverging 
bristles. Cephalic segment about as long as the 2 suc- 
ceeding ones taken together, with exceedingly elongate and 
slender neck; frontal part, comparatively, but little expanded. 
Oculiferous tubercle remarkably elevated, conically-acum- 
inated, higher than broad. Proboscis hardly more than half 
as long as the cephalic segment. Chelifori less powerful than 
in the preceding species, hand shorter than the scape, densely 
hirsute, fingers shorter than thepalm, about as in N. gracile. 
Palpi very slender, 2nd and 3rd joints nearlyequal in length, 
last joint twice as long as the penultimate one. False legs 
in male longer than the body ; 4th and 5th joints greatly 
elongated and slender, terminal part scarcely longer than 5th 
joint, with numerous marginal spines, similar in structure 
to those of N. gracile. Ambulatory legs exceedingly slen- 
der, more than 3 times longer than the body, and beset with 
scattered, highly chitinised bristles; femoral joint about as
