cies the much older name proposed by Boeck. Though rather nearly allied 

 to the type species, this form is easily distinguishable both by its much 

 smaller size and by several well-marked structural details; thus by the form 

 of the 4th pair of coxal plates and of the last pair of epimeral plates of 

 metasome, by the structure of the gnathopoda and of the telson, and finally 

 by the rather different coloration of the body. 



Occurn-uce. The only place, where I have met with this species, is 

 at Kopervik, west coast of Norway. It occurred here rather sparingly in a 

 depth of 4060 fathoms. 



Distribution. - Kullaberg (Lilljeborg), Shetland Isles (Norman), coast 

 of France (Chevreux, as L. furina}. 



Fam. 10. CEdiceridae. 



Body more or less tumid, with the coxal plates not very large and 

 fringed at the distal edge with setse. Metasome well developed, with the epi- 

 meral plates evenly rounded at the lateral corners. Urosome of normal 

 appearance. Cephalon more or less produced in front. Eyes, when distinctly 

 developed, contiguous, and placed at the end of the front dorsally. Antennae 

 more or less densely clothed with setse, some of which are generally plumose, 

 the superior one, as a rule, shorter than the inferior, and without any acces- 

 sory appendage. Epistome not projecting in front. Anterior lip rounded, 

 posterior lip well developed, with the inner lobes distinct. Mandibles short 

 and stout, molar expansion more or less developed, palp large and densely 

 setous. Maxillse normal. Maxillipeds with the masticatory lobes well develo- 

 ped, though generally not very large, palp robust, with the terminal joint 

 claw-like. Gnathopoda sometimes very strong, sometimes feeble, subcheliform, or 

 the posterior pair sometimes chelate. The 4 anterior pairs of pereiopoda gene- 

 rally rather stout and densely setous, with the meral joint more or less 

 dilated, basal joint of 3rd and 4th pair not very large, elliptical in form, and 

 fringed with long plumose setas; last pair very unlike the preceding pair, 

 much elongated, and turned posteriorly, basal joint laminarly expanded, outer 

 part minutely spinulose at the edges, terminal joint styliform. Branchial
