Occurrence. I have found this form occasionally in the upper part of the 

 Christiania Fjord, as also off the west coast of Norway in moderate depths among 

 algae. Out of Norway it has not yet been recorded. 



162. Laophonte proxima, G. 0. Sars, n. sp. 



(PI. CLXX). 



Specific Characters. Female. Body more slender than in the preceding 

 species, though, as in that form, conspicuously depressed, with the segments sharply 

 marked off from each other. Cephalic segment about as in L. Koreni; the 3 suc- 

 ceeding segments however more angular and less densely setous. Urosome rather 

 short, and having the lateral expansions of the segments less produced. Caudal 

 rami comparatively longer than in L. Koreni and gradually tapering distally, 

 apical setae less divergent. Anterior antennae more slender, with the 2nd and 3rd 

 joints of about equal length. Posterior antennas resembling in structure those in 

 L. Koreni. 1st pair of legs somewhat, less robust than in that species, otherwise 

 of a very similar structure. Natatory legs also rather similar, except that the 

 distal joint of the inner ramus in the 3rd pair of legs has 5 setae, and that the 

 outer ramus of the 4th pair is somewhat shorter and stouter. Last pair of legs 

 differing more conspicuously from those in L. Koreni, the distal joint being much 

 shorter and broader, obliquely oval in form, and very densely hispid, marginal 

 setae 6 in number, 2 of them on the outer edge closely juxtaposed. 



Colour not yet ascertained. 



Length of adult female 0.84 mm. 



Remarks. The present form is closely allied to L. Koreni, differing how- 

 ever in the more slender form of the body, as also in some of the structural 

 details, for instance in the shape of the distal joint of the last pair of legs. Only 

 the female sex is as yet known. 



Occurrence. Some few specimens of this form were picked up from a 

 sample taken at Kopervik, west coast of Norway, from moderate depth.
