Carinate (apparently) througbout, bind segments of peraeon projecting, 

 pleon Segments 1 — 6 each prolonged into dorsal tooth, large on P*^ — 3<^, on 

 3*^ upturned, in ö tooth on 5*^^ produced over 6**^, Q^^ fringed with close-set 

 spinules. Head carinate, rostrum sti'ongiy deflexed, acute, reaching apex 

 of P* Joint of antenua 1, lateral corners forming straight-fronted lobe. Side- 

 plates as in S. serratus (p. 279), unless 4*^ be a little deeper than 3^. Pleon 

 Segment 3, postero-lateral corners strongly produced, acute, margin above not 

 denticulate. Eyes wanting. Antenna 1 in 9 , 1^* Joint ending in a small 

 hook, 2"^ and 3*^ equal, flagellum subequal to peduncle, 9-jointed, accessory 

 flagellum small, 2-jointed. Antenna 2 in 9 equal to antenna 1, flagellum short, 

 7-jointed. Antenna 1 in d, 3*^ Joint shorter than 2*^, flagellum with 9 joints, 

 1^*^ as long as peduncle, longer than the other 8 combined, densely fringed 

 with sensory filaments, accessory flagellum 3-jointed. Antenna 2 in c? much 

 longer, ultimate Joint of peduncle rather longer than penultimate, flagellum 

 longer than peduncle. Epistome salient. Upper lip long, rounded. Other 

 mouth-parts nearly as in S. serratus, but maxilla 1, outer plate said to bave 

 12 spines, and maxillipeds have 11 spine-teeth of moderate size on outer 

 plates, which reach apex of palp's rather short 2*^ Joint. Triturating lobes 

 of stomach with 2 enormous spines in addition to the ordinary armature. 

 Gnathopods 1 and 2 as in S. seiTatus, but palm defined by a strong spine. 

 Peraeopods 1 — 5 similar to tbose of S. serratus but more slender, and 

 6*^ Joint in peraeopods 3 — 5 more elongate. Uropods 1 — 3 as in S. serratus. 

 Telson elongate triangulär, cleft to centre, apices notched. L. 7 mm.
