Body not carinate or dentate. Pleon segraeuts 5 and 6 not 

 coalesced. Side-plates 1 — 4 of moderate size, 4*^^ emarginate behind, b^^ 

 with hind lobe the deeper. Antenna 1 not longer than autenna 2, with 

 1-jointed accessory flagellum. Upper lip rounded. Mandible normal, but 

 3^ Joint of palp as long as 2*^. Maxilla 1, inner plate with many setae, 

 outer with 11 strong denticulate spines, 2^ Joint of palp with many spine- 

 teeth. Maxilla 2, inner plate fringed on inner margin. Maxillipeds, inner 

 plates rather large, outer not reaching apex of palp's 2^ Joint, fringed on 

 inner margin with spine-teeth. Gnathopods 1 and 2, 5^^ Joint shoi-ter than 

 6*^, especially in ö, 6**^ Joint oblong, much wider in ö than in 9, palm 

 not very oblique, well defined. Peraeopods 1 — 5, 5*^ Joint shorter than 6*^ 

 finger small. Branchial vesicies simple, üropods 1 and 2, outer ramus 

 the shorter; uropod 3, rami long, lanceolate, subequal, reaching back as far

Body rather compressed. Head, rostrum obsolete (Chilton: about ^/^ 

 as long as 1®* Joint of antenna 1), lateral margins inconspicuously bilobed, 

 post - antennal corners not produced. Pleon segment 3, postero-lateral 

 Corners rounded, segments 1 — 3 dorsally microscopically scabrous. p]yes rather 

 large, reuiform, black. Antenna 1, 1^* Joint as long as 2^ and 3*^ cqmbined, 

 flagellum tapering, with 16 — 55 joints, alternatejointswideningat apex, accessory 

 flagellum (Miers: not existing) consisting of 1 Joint shorter than P* of primary, 

 tipped with 2 setae. Antenna 2 scarcely longer (length variable, Haswell), 

 ultimate and penultimate joints of peduncle subequal, flagellum 20 — 56- 

 jointed. Gnathopods 1 and 2, 5*^ Joint in young and g not greatly 

 shorter than the narrowly oblong 6*^, in the ö much shorter, while the 

 6*^ Joint is much wider; both these joints in gnathopod 2 are longer than 

 in gnathopod 1, without being wider; the palm is^short, slightly oblique, 

 well defined by palmar spines. Peraeopods 3 — 5, 2^ Joint oval, widest on 

 the last pair. Uropod 3, rami more than twice as long as peduncle, acute, 

 with spines on each margin. Telson longer than peduncle of uropod 3, 

 about ^/g as broad as long, cleft % of length, tapering, with a spinule in 

 each bidentate apex (Chilton: oblong, cleft about to middle, apices rounded 

 on outer margin). L, reaching 17 mm.
