slightly transformed. Last pair of le<_:s forming each a slender curved stem ex- 

 tending laterally, its -2 joints imperfectly defined, the proximal one without any 

 distinct expansion inside, but produced outside to a slender digitifonn process 

 tipped with a delicate bristle; those in male comparatively smaller than in female, 

 with the -2 joints completely continent, and the number of seta- reduced. 



Remarks. This ^-iius \\a> established by Tli. Scott in the year 1SD4. and 

 was at first merely regarded as a submenus of /.'f<,/ili"i/fr. In my opinion it is a 

 fairly well defined genus, differing very markedly from the other genera comprised 

 within the present family in several of the structural details, for instance, in the 

 total absence of an outer ramus on the posterior antenna 1 , and in the rather 

 peculiar structure of the legs. OH' the coasts of Norway, there occur 3 well 

 defined sp, cies belonging to this genus.

Sf,,ri/ir {'Itni-iirtrrx.- Fi-nnilf. Body narrow, elongate, tapering behind. 

 with the segments more or less angular in form. Cephalic segment sub-quadrangular 

 in outline, postero-lateral corners only slightly produced. Rostral projection not 

 very prominent, and obtuse at the tip. Urosome very narrow and (including the 

 caudal rami) almost as long as the anterior division, lateral expansions of the 

 incuts well defined and minutely spinulosc at the edges; last segment almost 

 long as the preceding one. and ha\ing the anal opercle finely denticulate, caudal 

 i ami narro\\ linear in form and rather di\er-ent, being nearly twice as long as 

 the anal segment, seta- of outer edge somewhat distant, dorsal seta well developed 

 and issuing near the end of the ramus; middle apical seta rather strong, the 

 other -2 very small, the outeimost one being the longer, and connected at the base 

 with the middle one. . \nteiior antenna' rather slender, almost attaining the length 

 of the cephalic segment, and composed of ^ articulations. L'nd joint about the 

 length of the Mnl. and exhibiting behind a slight ciliated expansion; terminal part 

 I'ulU as loim as the :inl joint. Posterior antenna 1 with the distal joint long and 

 narrow, exhibiting the usual armature. Posterior maxillipeds not very strong, hand 

 nario\\ t'lisiform in shape. 1st pair of le^s with the outer ramus about half as 

 lon.u as the proximal joint of the inii'-r. L-eniculate spines of the last joint rapidly 

 increa-ing in length, the inneiniost one being .'! times as lon.i; as the whole 

 ramus. apii-al claw of inner ramus ,,| moderate si/e and much curved at the end.
