og noget krummet ; det er langs den ydre Kant og ved En- 

 den besat med korte Børster og har Underkanten 4 stærke 

 Torner, festede til særskilte Afsatser. Endekloen er neppe 

 halvt saa lang som Podleddet, men meget kraftig og stærkt 

 chitiniseret. Bikløerne er vel udviklede og omtrent halvt 

 saa lanse som Endekloen. 



Dyrets Farve er i levende Tilstand hvidagtig. halvt 

 giennenisigtigt. med et mere eller mindre tydeligt udpræget, 

 vakkert violet Pigment, der baade er afsat paa selve Krop- 

 pen og paa Lemmerne, hvor det danner tydelige Tvær- 

 baand. 



Forekomst. Jeg har kun tåget denne lille Art ved 

 vor Sydkyst (Bisøer, Arendal), hvor den forekom enkeltvis 

 paa ganske grandt Vand mellem Alger. Paa vort Universi- 

 tets Museum tindes Ogsaa nogle Exemplarer af denne Art 

 fra vor Vestkyst, indsamlede af min Fader, men bestemte 

 som N. brevitarse. Krøyer. 



Udbredning. Arten er utvivlsomt at betragte som 

 en mere sydlig Form. Foruden ved Norge er den nemlig 

 noteret fra de britiske Øer (Leach, Johnston), Danmark 

 (Hansen), Holland og Nordkysten af Frankrige (Hoek). 

 Derhnod er den ukjendt i de arktiske Have.

Artscharaeter. Legemet særdeles smalt og lang- 

 strakt, med vidt adskilte forlængede Sidefortsatser, enhver 

 ved Enden oventil forsynet med 2 stive divergerende Bør- 

 ster. Hovedsegmentet omtrent saa langt som de 2 følgende 

 Segmenter tilsammen, med stærkt forhenget og smal Hals; 

 Pandedelen forholdsvis kun lidet udvidet. Øieknuden stærkt 

 ophøiet, konisk tilspidset, høiere end bred. Snabelen neppe 

 mere end halvt saa lang som Hovedsegmentet. Saxlem- 

 merne svagere end hos foregaaende Art, Haanden kortere 

 end Skaftet, tæt haaret. Fingrene kortere end Palmen, om- 

 trent som hos N. gracile. Følerne spinkle, 2det og 3die 

 Led omtrent af ens Længde, sidste Led dobbelt saa langt 

 som næstsidste. De falske Fodder hos Hannen hengere 

 end Legemet ; 4de og 5te Led særdeles stærkt forlængede 

 og tynde; Endepartiet neppe hengere end 5te Led, med 

 talrige Randtorner, de sidste af en lignende Bygning som 

 hos N. gracile. (xangfødderne særdeles spinkle, over 3 

 Gange hengere end Legemet, og besatte med spredte, stærkt 

 chitiniserede Børster; 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 tåken 

 exclusively on the south coast of Norway (Risøer. Arendal), 

 where it is sparingly met with in very shallow water be- 

 tween algæ. In our University Museum there are a few 

 specimens of this form from the west coast of the country 

 collected by my late fatlier, but determined as N. brevitarse, 

 Kroyer. 



Distribution. The speeies 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.

Speciflc 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 tåken toget her, with exceedingly elongate and 

 slender neck; frontal part, comparatively, but little expanded. 

 Ocuhferous tubercle remarkably elevated, eonically-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 ord 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 oth 

 joint, with numerous marginal spines, similar in structure 

 to those of N. gracile. Ambulatory legs exceedingly slen-

 scattered, highly chitinised bristles; femoral joint about ;is
