Colour of female pale orange, ovisac dark bluish. 



Length of adult female 0.64 mm. 



RemarJcs.This form was first recorded from the Arctic Ocean by Th. Scott, 

 who considers it to be most nearly allied to the 2 species L. ciirlirmtilti Boeck 

 and L. snailix Glaus. It is however undoubtedly much more closely related to 

 L. Irevirostris Glaus (= L. H<.'nlni<ini Scott), though differing both from that 

 species and the nearly-allied L. congenera G. 0. Sars. in the structure of the 1st 

 pair of legs, the outer ranius of which is only Inarticulate. It is also of rather 

 larger size than either of these 2 species. A remarkable feature in the present 

 species is that the inner ramus of the 3rd pair of legs in the male does not 

 exhibit any trace of the conspicuous transformation found in all other species 

 of the genus Laophoute. 



Occurrence. I found this form, many years ago, not infrequently off the 

 Finmark coast, at Hammerfest and Vadso, and it has also been recorded by Th. 

 Scott from that part of our country. It moreover occurs in the Trondhjem Fjord, 

 at Selven, and occasionally also at Kopervik and Bukken on the south-west coast 

 of Norway, in moderate depths. 



Distribution. Franz Josef Land (Scott), Polar islands north of Grinnell 

 Land (2nd Fram-Expedition)

Specific Characters. -Fanulr. Body slender and narrow, with the segments 

 sharply marked off from each other, and the integuments of very coarse consistency. 

 Cephalic segment comparatively large and deep, with the rostral projection not 

 very prominent, and blunted at the tip. The 4 succeeding segments much nar- 

 rower and rounded laterally. Urosome almost as long as the anterior division, 

 and having the lateral expansions of the segments rather prominent. Caudal rami 

 considerably produced, being about 4 times as long as they are broad, and nar- 

 row linear in form; apical setre of moderate length. Anterior antennae 7-articulate, 

 with the 2nd joint simple and about the length of the 3rd. Posterior antennae 

 with the outer ramus comparatively small, but of normal structure. Posterior 

 maxillipeds largely developed. 1st pair of legs with the outer ramus biarticulate, 

 and scarcely exceeding half the length of the proximal joint of the inner. Natatory 

 legs of normal structure. Last pair of legs with the distal joint of moderate size 

 and oval in form, inner expansion of proximal joint comparatively short, not ex- 

 tending to the middle of the distal joint. Ovisac small, rounded.
