slightly transformed. Last pair of legs 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 digitiform process 

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

 with the 2 joints completely confluent, and the number of setcc reduced. 



Remarks. This genus was established by Th. Scott in the year 1894, and 

 was at first merely regarded as a subgenus of Laophontc. 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 antennae, and in the rather 

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

 defined species belonging to this genus.

Specific Characters. Female. 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 

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

 as long as the preceding one, and having the anal opercle finely denticulate, caudal 

 rami narrow linear in form and rather divergent, being nearly twice as long as 

 the anal segment, setse 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 outermost one being the longer, and connected at the base 

 with the middle one. Anterior antennae rather slender, almost attaining the length 

 of the cephalic segment, and composed of 5 articulations, 2nd joint about the 

 length of the 3rd, and exhibiting behind a slight ciliated expansion; terminal part 

 fully as long as the 3rd joint. Posterior antennae with the distal joint long and 

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

 narrow fusiform in shape. 1st pair of legs with the outer ramus about half as 

 long as the proximal joint of the inner, geniculate spines of the last joint rapicll} 

 increasing in length, the innermost one being 3 times as long as the whole 

 ramus, apical claw of inner ramus of moderate size and much curved at the end
