on the hind edge, propodal joint of the latter pairs much elongated and very 

 slender. Last pair of uropoda reaching somewhat beyond tlie preceding pairs, 

 rami narrow lanceolate and nearly si;bequal in length, terminal joint of the 

 outer ramus comparatively short. Tel son rather large, oblong triangular in 

 form, more than twice as long as it is broad, outer part evenly tapering, 

 cleft extending far beyond the middle, terminal lobes bidentate at the tip. 

 Colour yellowish grey, without any pigmentary ornament. Length of adult 

 female 8 mm., of male about the same. 



Iic-iiinrls. — As mentioned above, this form was at first described by 

 the author under the name of Bruselia serrata, from a few female specimens 

 collected during the Norwegian North Atlantic Expedition. I have subse- 

 quently found it, in both sexes, on the Norwegian coast, and a redescription 

 of the species would thus seem to be not inappropriate. The peculiar jagged 

 upper contour of the body will suffice to distinguish this form at once from 

 any of the other Si/rrhoi(ke. 



Occurrence. — I have met with this interesting form in 4 different 

 localities of the Norwegian coast, viz., in the Korsfjord, south of Bergen, in 

 the Trondhjemsfjord, at Selsovig on the Nordland coast, and on the Lofoten 

 Isles. It occurred in all these localities ratlier sparingly, in a very great depth, 

 ranging from 150 to 300 fathoms. The specimens procured during the Nor- 

 wegian North Atlantic Expedition were collected west of the Helgeland coast, 

 from a depth of 350 fathoms (cold area). Out of Norway it has not yet 

 been recorded.

Body comparatively stout and very broad, with strongly incrusted 

 integuments. Cephalon large, and produced in front to a variously formed 

 rostrum, lateral parts much expanded. Coxal plates resembling those in 

 Syrrhoiles. Metasome well developed; urosome short and depressed. Eyes 

 rudimentary and replaced by an irregular patch of pigment, without any 

 trace of visual elements. Superior antennae about as in Syrrhoites ; inferior 

 ones longer than the former, and very elongated and slender in the male. 

 Oral ])arts somewhat resembling those in Sijrrhoites. Anterior lip, however, 

 comparatively larger, and having along the middle a projecting keel; inferior 

 lip witli the lateral lobes not insinuated at the tip. Mandibles of a similar
