Posterior gii;itlio[)<i(la witli tlie i)i'opo(lo.s very large, gradually expanded di- 

 stally, palmai' edge defined below b}' a projecting angle and coarsel}' denti- 

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

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

 i-egularl)' 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 dentiides, cleft extending beyond tlie middle and gradu;illy widening 

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

 lour not .stated. Length of adult female 14 mm. 



Ileniuii's-. — There cannot, I think, be an}- douljt that tlie form de- 

 scribed by Hoelv as Anonyx Dehfii'piii is identical \\ith the present foi'm, 

 although the numljer cd' articulations in tlie antennal flagella is much greater; 

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

 young male. It is noAv 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 Christiansund on the West coast of Norway, the 

 two off the Lofoten isles; depth fiO— 100 fathoms. 



Disfrihiifioii. — The Barents Sea (Hoek). 



rien. ii, Menigrates, Boeck, 1870. 



Body of unusually coarse structure, with I'ather lai'ge coxal plates 

 and the last pair of ejiimeral ])la.tes of metasome produced at the lateral 

 corners. Antenna? in Ijoth sexes short and stout, those of the male provided 

 with very distinct calceolae. Epistome tiattened in front and not distinctly 

 defined from the anterior Yi-p, botli together forming a rather narrow fla^o- 

 slia])ed projection. Po.sterior lip with the lobes narrowly rounded at the tip. 

 Mandibles rather elongated, cutting edge sim])le, molar expansion very slight, 

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

 latter. First pair of maxillae nearly as in Oncsimns; second pair with the 

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

 Maxillij)eds with the masticatory lol)e rather large, reaching considerably 

 beyond tlic antejienultimate joint of tlic [lalji, the latter not very large. An- 

 terior gnatliopoda iiot subcheliforni, the propodos wanting any distinctly de- 

 fined palmar edge. Posterior gnathopoda very slender, projiodos not at all 

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