Anteniia 1, P^ Joint % as long as 2'\ 3*^ less than half as long as 1**^ flagellum 

 longer than peduncle, 20-jointod, accessory flagellum 8-jointed. Antenna 2 

 shorter. ultiraate Joint of peduncle as long as penultiraate, longer than the 

 8-jointed flagellum. Upper lip semicircular. Mandible, 3*^ Joint of palp longer 

 than 2*^. Maxiila 1, inner plate rudimentary, without setules. Maxillipeds, outer 

 plates rather large, strongly armed. Gnathopod 1 in d, 5*^ Joint a little 

 shorter than ß*''; 6^^ oval, palm slightly oblique, well defined, but without 

 a tooth, a small cavity occupying about 7« of its length adjacent to the 

 defining angle, which is slightly overlapped by the serrate finger. Gnatho- 

 pod 2 in d rather smaller, similar, except that the palm is more oblique, 

 simply and slightly convex. Gnathopod 1 in 9 , palm straight, oblique, 

 otherwise nearly as in d. Gnathopod 2 in 9 narrower than gnathopod 1, 

 palm less oblique. Peraeopods 1 and 2 as in L. arcticus (p. 595), or finger 

 rather longer. Peraeopods 3 — 5 as in L. arcticus, except that the 2*^ Joint 

 is rather more expanded, especially in peraeopod 5. Pleopods 1—3, peduncle 

 rather large, outer ramus the shorter. üropod 3, peduncle short and stout, 

 rami twice as long as peduncle, nearly equal. Telson longer than broad, 

 a setule in the indent on each side of rounded apex. Colour, bands of rose 

 alternating with sulphur-yellow or white. L. 5 — 7 mm.

Side-plate 1 in d subacutely produced, in 9 subrhomboidal. Pleon 

 Segment 3, postero-lateral corners obtusely quadrate. Eyes small. Antenna 1, 

 1^* Joint rather long, rest unknown. Antenna 2, antepenultimate Joint of 

 peduncle much thicker than penultimate, ultimate rather shorter than penultimate 

 and longer than the 4- or 5-jointed flagellum. Gnathopod 1 in ö, 2^ Joint with 

 brush of long setae at bind distal end; 5*^ Joint nearly as broad as 6*^ but con- 

 siderably shorter; 6*^ broad, oblong, palm transverse with deep narrow cleft 

 between a submedian tooth and the rather long and sinuous defining tooth, 

 beyond which the apex of the denticulate finger projects. Gnathopod 2 ind, 

 2^ Joint somewhat expanded, oval; 5*^ Joint rather longer and broader than the 

 oblong 6*^, both setose on both margins, the 5*^ having a group of very long 

 setae at the bind apex, and the 6*^ many such along the front; palm short, not 

 sharply defined, overlapped by the finger. Gnathopod 1 in 9 , 2"^ Joint slender, 

 unarmed, 6*^ Joint much longer than 5*^ and slightly broader, palm with 

 a little triangulär indentation. Gnathopod 2 in 9 , 2^ Joint slender, other joints 

 nearly as in d, but 5*^ and 6*^ much more sparsely furnished in front 

 though similarly on the bind margin. Peraeopods 1 and 2 in d, but not 

 in 9 , having the large 4*^ Joint on both margins densely fringed with long 

 simple setae. Peraeopod 3, 2*^ Joint moderately expanded, 6*^ longer than 

 4th QY 5th^ slightly curved, reverted; finger short. Peraeopod 4 longer, 6*^ Joint 

 straight, not reverted, finger short. Peraeopod 5? Pleopods 1 — 3, outer 

 ramus much shorter than inner, both with 10 joints. üropod 3, rami equal. 

 Telson as long as broad, with 2 setae at each lateral process, apex rounded. 

 L. 4 mm.
