Gnathopoda in female rather feeble and densely supplied with bristles, carpus 

 elongated and somewhat expanded below, especially in the posterior pair, 

 propodos shorter than the carpus and oblong oval in form, with the palm 

 scarcely defined in the anterior pair, and having in the posterior pair a 

 slender spine below ; gnathopoda in male somewhat stronger than in female, with 

 the carpus more expanded, propodos in the anterior pair having a slender 

 spine at the end of the palm, in the posterior pair produced below to an 

 acute, thumb-like projection, at the base of which occurs a small spine. The 



2 anteriors pairs of pereiopoda nearly twice as long as the gnathopoda; the 



3 posterior pairs still longer; last pair attaining the length of the body, 

 without the urosome. The 2 anterior pairs of uropoda rather slender, with 

 the rami linear and edged with scattered spines, outer ramus a little shorter 

 than the inner; last pair only represented by 2 very small lamellae covered 

 by the telson. The latter terminating in an obtuse point. Body greyish 

 white, with slight transverse bands of a somewhat orange hue. Length of 

 adult specimens, according to Boeck, 14 mm. 



Bemarkx. - This form was described, but not figured, by Boeck in 

 his great work, as the type of his genus X<'iw<lice. It is easily recognized 

 by its long and slender body, and the very much elongated antennae and 

 legs. But, as the animal is exceedingly fragile, it is very unusual to get any 

 specimen with all its appendages uninjured. The figure here given was 

 drawn from a young female specimen, immediately after being dredged, and 

 while still in a living state. 



Occurrence. The only place, where I have hitherto met with this 

 form, is at Bejan at the entrance to the Trondhjemsfjord, where some spe- 

 cimens were collected from a depth of 80 100 fathoms. Boeck records it 

 from 2 other localities of the Norwegian coast, viz., from the Hardangerfjord 

 and the Lofoten islands (Skraaven). Out of Norway, it has not yet been 

 recorded.

 Syn.-. Dyopedos, Sp Bate. 



Body slender and narrow, with the last 2 segments of mesosome 

 coalesced. Metasome poorly developed, 1st segment of urosome elongated 

 and slender. Cephalon produced in front to a hooded prominence, lateral 

 lobes obsolete. Coxal plates very small, 2nd pair in male generally larger 

 than in female. Eyes either well developed or wanting. Antennae very slender
