Pleon Segments 1^ — 6, none serrate or emarginate, segmeut 5 with 

 several slender spines on each side near median dorsal line. Eyes small, 

 round, black. Antenna 1 about -/g as long as body, 2^ Joint slightly longer 

 than 1^*, nearly twice as long as 3'^, flagellum longer than pediincle. Antenna 2 

 shorter, but with longer peduncle, ultimate Joint of peduncle rather longer 

 than penultiraate. Gnathopod 1, ö^^ Joint longer and broader than 6*K which 

 is oblong, slightly curved, finger very small but stout, curved, attached in notch of 

 apex of 6***joiut, not closing on palm but projectiug inwards. Gnathopod 2 stout, 

 5*^ Joint Short, triangulär, 6^^ somewhat oval, palm oblique, arcuate, conti- 

 nuous with bind margin, with spinules and stiff hairs, tip of finger resting 

 within the palmary margin. Peraeopod 1 rather longer than peraeopod 2. 

 Peraeopods 3 — 5, 2*^ Joint minutely serrate behind, üropod 2 not reaching 

 quite so far as uropod 1. Uropod 3 very long, with fascicles of spines 

 along the margins. Lobes of telson slender, with spines at the tips. Colour 

 dark greenish-slate. L. 7 — 9 mm.

Body rather slender, with no dorsal teeth, but some simple bristles on 

 pleon Segments 4 and 5. Head, lateral corners brojidly rouuded, post- 

 antennal corners to the rear but distinct. Side-plate 1 expanded distally, 

 4*^ quadrate below the emargination. Pleon segment 3, postero-lateral 

 corners acute, but scarcely produced. Eyes small, rounded oval, black. 

 Antenna 1 about -/s as long as body, P* Joint fuUy as long as 2*, 3"^ more 

 than half as long as 2*^, flagellum nearly twice as long as peduncle, 18-jointed, 

 accessory flagellum very small, l-jointed. Anteuua 2 scarcely more than ^/„ 

 as long as antenna 1, ultimate and penultimate joints of peduncle subequal, 

 together longer than flagellum. Gnathopod 1, 6*^ Joint little more than 

 */.^ as long as 5*^\ subquadrate, palm distinctly defined, transverse. Gnatho- 

 pod 2 in 9 larger, 6*^ Joint a little longer than ö*^ and broader, oval, 

 but with palm nearly transverse, defined by a distinct angle and 2 palmar 

 spines, in ö similar, but with 5**^ Joint shorter, and 6*^ considerably larger. 

 Peraeopods 3 — 5 rather strongly built, 2*^ Joint rather broadly oval. Uropod 3, 

 peduncle about ^/g as long as outer ramus, which has apex obliquely truucate, 

 armed with many unequal spines, inner ramus not twice as long as broad. 

 Telson broader than long, not cleft to the base, the dehisceut lobes obtusely 

 rounded, with several apical spines. Colour whitish, pellucid. L. ö 6 mm. 

 9 considerably less.

Pleon Segments 1 — 4 entirely unarmed, segmeut 5 produced into 3 

 dorsal denticles with a bristle in each of the intervals (the figured small 

 7^^ segment is an eiTor). Eyes small, round, black. Antenna 1 almost as 

 long as body, 2^ Joint longer than P*, flagellum of more than 40 joints, 

 accessory flagellum of 4 rather elongatC' joints. Antenna 2 shorter, flagellum 

 much shorter than peduncle, about 20-jointed. Gnathopod 1, 6*^ Joint 

 shorter than 5**^, narrow proximally, distally a little widened, palm short. 

 defined by a projecting rounded lobe, behind which the point of the finger 

 closes down. Gnathopod 2, 6*'^ Joint in ö rather tumid, oval, palm weakly
