Pleon Segments 1—5 dorsally dentate, 1^* and 2^ haviug 5 teeth each, 

 3^^ a vevv minute tooth- between two rounded lobes, 4*'* and 5*^ carinate 

 each witb a streng tootb: peraeon segments 6 and 7 with a dorsal tooth (?). 

 Head, rostrura very distinct. narrow, acute, lateral corners broadly rounded. 

 Side-plates 1--3 with very small denticles at the corners, 4*'^ with 2 teeth on 

 the bind margin. Pleon segments 2 and 3, postero-lateral corners acute, very 

 sligbtly produced. P^yes oval, not large, remaining dark in spirit. Antenna 1, 

 1^^ Joint fully twice as long as 2*^ and 3'^ combiued, flagellum mucli longer than 

 peduncle, 34-jointed, accessory flagellum more than half as long, 18-jointed. 

 Antenna 2 eonsiderably longer, penultimate Joint of peduncle long, but shorter 

 than ultimate, flagellum shorter than both combiued, 24-jointed. Maxilla 1, 

 inner plate with, 1 seta. Gnathopods 1 and 2 in 9 nearly as in L. consanguinea, 

 but 6^'^ Joint more broadly oval. In the d gnathopod 2 has the palm of 

 6^'' Joint well defined, but rather coucave than convex, the Joint distally 

 uarrowed, with the palm produced into a blunt tooth, strong but variable 

 in length, with a cavity between it and the lobe adjoining the hinge of the 

 finger; inner margin of the finger somewhat convex at the middle, cut into 

 teeth. Peraeopods 1 — 5, finger short. Peraeopods 3 — 5, 2<* Joint rather 

 broad, bind margin not very convex, strongly serrate. üropod 3, rami 

 lauceolate, inner rather the broader and longer, with 4 spiues on the inner 

 margin. Telson long and narrow, cleffc nearly to the base, outer point of 

 bidentate apices produced much beyond the inner, a long spine in each 

 notch. Colour in spirit showing a lustrous green on many parts. L. 15 mm, 

 but often much smaller.

Body very short and stout. Pleon segments 1, 2, 4 and 5 each produced 

 into a well marked dorsal tooth, this in segments 1 and 2 (Sars) accompanied 

 by a smaller tooth on each side. Peraeon segments 5 — 7 and(?) pleon 

 Segment 3 dorsally dentate (Bäte). Head, rostrum distinct, lateral corners 

 obtusely acuraiuate. Side-plate l broader than 2'^ or 3^, but scarcely expanded 

 distally, Pleon segment 3, postero-lateral corners acute, sligbtly upturned, 

 with very small sinus above. Eyes small, round, black. Antenna 1 short, 

 flagellum not nearly twice as long as peduncle, 12-jointed, accessory flagellum 

 more than half as long, 7-jointed. Antenna 2, ultimate Joint of peduncle scarcely 

 longer than penultimate. Gnathopod 1 as in L. brevicornis (p. 231), but 2*^ Joint 

 abruptly dilated uear base, finger with only 3 teeth at base. Gnathopod 2, 

 finger with 6 teeth on proximal half. Peraeopod 5, 'o^'^ Joint setose on 

 outer margin, finger about half as long, very slender. üropod 3, outer 

 ramus quite unarmed, inner with a Single spinule on inner margin. Telson 

 cleft nearly to base, lobes divergent, a long spine in the notch of each 

 apex, th^ points of the apices level. Colour whitish, pellucid (Sars), in
