Characters.- A"-//"//'. Rather like N. loniiiruwlnta, hut of somewhat 

 -mailer xi/e and. when \iewed dorsally, at once distinguished by the epimeral 

 plate- <>!' the 4 anterior segments being expanded laterally, forming together a 

 broad hyaline rim surrounding the anterior part of the body, edges of the plates 



\ finely spiniilo-e. l"ro-ome with the segments very sharply marked oil from 



h other, the lateral parts forming in all of them, except the last, lamellar 

 .\p:m-ioiis den^i-ly spinulose at the edges. Posterior edges of all the segments 

 of the hodv >nni'-\vhat raised dorsally, and clothed with very coarse spinules. 



nl.il rami. as in the type species, narrow linear in form and exceeding half 

 the length of the urosome, apical seta? long and slender. Anterior antennae 

 -milling in structure those in S. lon<iic<imlt<i, though differing somewhat in the 

 mutual relation of the joints in the proximal part, the 1st joint being only slightly 

 longer than the 2nd. which is fully as long as the 2 succeeding joints combined. 

 I'.'-terior antenna' with the outer rarous comparatively smaller than in that species, 

 though of a \ery similar structure. 1st pair of legs with the outer ramus much 

 shorter than the 1st joint of the inner, the latter very narrow and somewhat 

 -iiMiioid in -liape. The 3 succeeding pairs of legs comparatively smaller than in 

 the typ.' -pecies, and having the basal part bent in an elbow-like manner, as 

 in >. both rami very narrow. Last pair of legs comparatively small, 



with the distal joint narrowly exserted at the tip; inner expansion of proximal 

 joint considerably smaller than in S. Ion yicau data and defined outside by 

 an angular sinus.

 length of adult female 0.80 mm. 



Remarks,- This form is closely allied to 8. longicaudata, and was indeed 



1 by 'I'h Scott to be only a variety of that species Having, however, 



"ii r comparison of both forms, found several perfectly constant differences, 



bo*h a- regards tin- external appearance and some of the structural details, I am 



led to the conclusion that the present form should more properly be separated 



di-tinct though closely-allied species. 



This form was found last summer rather abundantly at Kors- 

 havn in B d.-pth of 30 ->^ fathoms, coarse sandy bottom. In the same locality 



'"'"/' ' aKo oceiirred; but it was fairly easy to pick out the present form, 



"ii account of its c tarselj spinulose body and the laterally expanded epimeral 

 pl:it"-s of the .'interior N.-gnn-nts, which, in the dorsal aspect of the animal, give 

 it a rather prrnliar appe.-irance.
