Posterior gnathopoda with the propodos very large, gradually expanded di- 

 stally, palmar edge defined below by a projecting angle and coarsely denti- 

 culated in its outer part, dactylus much curved and likewise denticulated 

 on the concaved edge. Basal joint of the last pair of pereiopoda 

 regularly oval in form and about as long as the remainder part of the leg". 

 Last pair of uropoda with the rami nearly equal in length and broadly 

 lanceolate. Telson nearly twice as long as broad and without any trace of 

 dorsal denticles, cleft extending beyond the middle and gradually widening 

 in its outer part, terminal lobes blunt, each with a small apical denticle. Co- 

 lour not stated. Length of adult female 14 mm. 



Remarks. There cannot, I think, be any doubt that the form de- 

 scribed by Hoek as Anonyx Debrwjnii is identical with the present form, 

 although the number of articulations in the antennal flagella is much greater; 

 but this may perhaps be accounted for by the specimen of Hoek being a 

 young male. It is now for the first time added to the Norwegian fauna. 



Occurrence. - I have as yet only met with 3 specimens of this form, 

 one of which was found at Christian sund on the West coast of Norway, the 

 two off the Lofoten isles ; depth 50 100 fathoms. 



Distribution. The Barents Sea (Hoek). 



Gen. 27. Menigrates, Boeck, 1870. 



Body of unusually coarse structure, with rather large coxal plates 

 and the last pair of epimeral plates of metasome produced at the lateral 

 corners. Antennse in both sexes short and stout, those of the male provided 

 with very distinct calceolse. Epistome flattened in front and not distinctly 

 defined from the anterior lip, both together forming a rather narrow flap- 

 shaped projection. Posterior lip with the lobes narrowly rounded at the tip. 

 Mandibles rather elongated, cutting edge simple, molar expansion very slight, 

 palp of moderate size and originating much nearer the base than does the 

 latter. First pair of maxilla3 nearly as in Onesimus; second pair with the 

 inner lobe somewhat more elongate, though a little shorter than the outer. 

 Maxillipeds with the masticatory lobe rather large, reaching considerably 

 beyond the antepenultimate joint of the palp, the latter not very large. An- 

 terior gnatliopoda not subcheliform, the propodos wanting any distinctly de- 

 fined palmar edge. Posterior gnatliopoda very slender, propodos not at all 

 produced beneath the minute dactylus. Pereiopoda very strong and stout,
